    How Close Are the Planet’s Climate Tipping Points?

    Right now, every moment of every day, we humans are reconfiguring Earth’s climate bit by bit. Hotter summers and wetter storms. Higher seas and fiercer wildfires. The steady, upward turn of the dial on a host of threats to our homes, our societies and the environment around us. We might also be changing the climate […] More

    In Paris, the Olympics Clean Up Their Act

    How do you produce a global sporting event, with millions of people swooping down on one city, in the age of global warming?That is the test for the Paris Olympics this summer.The organizers say they’re putting the games on a climate diet. These Olympics, they say, will generate no more than half the greenhouse gas emissions of recent Olympics. That means tightening the belt on everything that produces planet-warming emissions: electricity, food, buildings, and transportation, including the jet fuel that athletes and fans burn traveling the world to get there.An event that attracts 10,500 athletes and an estimated 15 million spectators is, by definition, going to have an environmental toll. And that has led those who love the games but hate the pollution to suggest that the Olympics should be scattered around the world, in existing facilities, to eliminate the need for so much new construction and air travel. That’s why Paris is being watched so closely.It is making more space for bikes and less for cars. It’s doing away with huge, diesel-powered generators, a fixture of big sporting events. It’s planning guest menus that are less polluting to grow and cook than typical French fare: more plants, less steak au poivre. Solar panels will float, temporarily, on the Seine.But the organizers’ most significant act may be what they are not doing: They aren’t building. At least, not as much.Construction of bike lanes at Boulevard Haussman.Yulia Grigoryants for The New York TimesWe are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Inside the E.P.A. Decision to Narrow Two Big Climate Rules

    Michael Regan, the E.P.A. administrator, said the Biden administration would meet its climate goals despite tweaking regulations on automobiles and power plantsPresident Biden’s climate ambitions are colliding with political and legal realities, forcing his administration to recalibrate two of its main tools to cut the emissions that are heating the planet.This week the Environmental Protection Agency said it would delay a regulation to require gas-burning power plants to cut their carbon dioxide emissions, likely until after the November election. The agency also is expected to slow the pace at which car makers must comply with a separate regulation designed to sharply limit tailpipe emissions.Michael S. Regan, the administrator of the E.P.A., said on Friday that changes to the two major regulations wouldn’t compromise the administration’s ability to meet its target of cutting United States emissions roughly in half by 2030. That goal is designed to keep America in line with a global pledge of averting the worst consequences of a warming planet.“We are well on our way to meeting the president’s goals,” Mr. Regan said in a telephone interview from Texas. “I am very confident that the choices we are making are smart choices that will continue to rein in climate pollution.”But experts said the Biden administration is making significant concessions in the face of industry opposition and unease in the American public about the pace of the transition to electric vehicles and renewable energy, as well as the threat of legal challenges before conservative courts.“There are two key factors: the Supreme Court, and the election,” said Jody Freeman, the director of the Harvard Law School Environmental and Energy Law Program and a former Obama White House official. “There are some adjustments needed for both,” she said. “You’ve got make sure these final rules are legally defensible, and you’ve got to make sure you’ve done enough for the stakeholders that you have support for the rules.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Climate Activists and Steve King Unlikely Allies in Iowa Pipeline Fight

    Liberal environmentalists and conservative landowners, led by the former congressman Steve King, are pressuring Republican candidates to oppose three Midwestern pipelines.Emma Schmidt, a lifelong environmental activist in Rockwell City, Iowa, had long searched for potent allies in her fight against a massive carbon dioxide pipeline planned for her state.But she never expected to find herself at former Representative Steve King’s house, making her case as she stared up at a pistol in the paw of a taxidermied raccoon in his home office.That meeting in June between a liberal Democrat and a conservative Republican who lost his seat in Congress in 2020 after incendiary racist comments was the beginning of a left-right alliance that is trying to push the debate of the pipeline to the forefront of the heated G.O.P. presidential caucuses.“We’re putting in a whole lot of money into pipelines that are not necessary, that bulldoze their way through some of the richest farmlands in the world, to sequester CO2,” said an incredulous Mr. King on Tuesday.Steve King, a former member of Congress who lost his seat after a series of racist comments, is an unlikely ally for liberal climate activists in Iowa. Joshua Lott/Getty ImagesThe $4.5 billion Summit, $3 billion Navigator and $630 million Wolf Carbon pipelines may not be front and center next month at the first Republican presidential debate. They probably won’t be featured in super PAC advertising or mentioned during Fox News appearances. But the pipelines capture a national debate with local consequences, and they will give candidates a chance to showcase their understanding of Iowa, the first state to weigh in on the Republican nominating fight — if they can navigate the issue.The Summit, Navigator and Wolf pipelines, fueled by federal tax credits embraced by both parties, would draw carbon dioxide from the factories that turn Iowa corn into ethanol. They would snake through 3,300 miles of farmland in Iowa and other Midwestern states, then pump the planet-warming gas into the bedrock beneath Illinois and North Dakota. And they are pitched as a climate protection measure, though some experts and environmentalists say it is only a partial solution at best.Earlier this month, an Iowa woman seemed to stump the front-runner, former President Donald J. Trump, when she asked how he would “help us in Iowa save our farmland from the CO2 pipelines.”Mr. Trump stammered that he was “working on that” and that he “had a plan to totally, uh, it’s such a ridiculous situation,” before reassuring the crowd, “if we win, that’s going to be taken care of.”The moment has been laughed off as a show of Mr. Trump’s ability to bluster his way through anything, but the issue is tricky: Several of the Republican candidates have cast doubt on the established climate science and would seem disinclined to back a project aimed at reducing carbon emissions. But opposing the pipeline also means opposing Iowa’s all-important ethanol industry.The state’s popular Republican governor, Kim Reynolds, has avoided taking a public position. Opponents believe she supports the deal, which is backed by some of her biggest political contributors, including Bruce Rastetter, founder of the Summit Agricultural Group. Ms. Reynolds’s office did not respond to requests for comment.The state’s popular Republican governor, Kim Reynolds, has avoided taking a public position on the pipeline, which is backed by one of her biggest political contributors. Kelsey Kremer/The Des Moines Register, via Associated PressPowerful figures from both parties have signed with the pipeline companies, including Terry Branstad, Ms. Reynolds’s predecessor, and Jess Vilsack, the son of another former Iowa governor and the current Democratic secretary of agriculture, Tom Vilsack. Agriculture giants like John Deere and A.D.M. have invested in the efforts.Presidential candidates have tried to skirt the issue; most campaigns declined to comment, including Mr. Trump’s. But campaign aides said this week that they knew a time for choosing was coming. The first public hearings on the Summit pipeline will begin on Aug. 22 in Fort Dodge, Iowa.Gov. Ron DeSantis of Florida is expecting questions later this week in a swing through the state, according to people familiar with the campaign.The left-right alliance is giving voice to Iowa landowners infuriated by the prospect that their land could be seized by eminent domain for the pipelines. Tim Baughman, who farms 330 acres with his sister in Crawford County, Iowa, brought his anti-pipeline sign to a Vivek Ramaswamy event in Dennison, eliciting a promise from the Republican entrepreneur to oppose the projects.“I’m fighting this to the end,” vowed Dan Wahl, who grows corn, soybeans and alfalfa on 160 acres near Spirit Lake, Iowa, and recently chased Summit surveyors off his land.The left-right alliance is giving voice to Iowa landowners concerned about the prospect that their land could be seized by eminent domain for the pipelines. Walker Pickering for The New York TimesSupporters — including agribusiness conglomerates and oil and gas tycoons — see the projects as a way to persuade liberal states like California it is possible to both continue ethanol production and fight global warming. If it works, so-called carbon capture and sequestration, the practice of removing carbon dioxide from the atmosphere, could be expanded to oil and gas, extending the life of the fossil fuel economy.Dean Ferguson, president of the Canada-based Wolf Carbon Solutions’s American subsidiary, said in a statement that he was hopeful that the pipeline planned from Iowa to Illinois would be built through voluntary easements.“Our approach is to build lasting relationships with landowners, so we can work together for years to come,” he said.In a statement, Summit Carbon Solutions said 75 percent of Iowa landowners along the project route had signed voluntary easements “and more are signing every day.”To opponents, the pipelines are dangerous, taxpayer-subsidized boondoggles that will destroy farmland and do nothing to curb global warming. A carbon dioxide pipeline ruptured in tiny Satartia, Miss., in 2020, sending 40 people to the hospital, forcing the evacuation of more than 300 others and releasing more than 31,000 barrels of carbon dioxide into the atmosphere.“Climate change money should be spent on things that are proven to actually work,” said Jessica Mazour, the conservation program coordinator of the Sierra Club in Iowa, who is helping to unite environmental activists with conservative farmers who doubt climate change is real.The unusual alliance can be strained. Sherri Webb, 73, who owns 40 acres of farmland in Shelby County, Iowa, said she had her doubts about climate change: “I don’t believe it’s as bad as some people are thinking.” If anything, she added, she worries more about taking carbon dioxide out of the atmosphere and away from her crops.But it was the threat of eminent domain that got her involved in the fight against the Summit pipeline. Summit Carbon Solutions says the pipeline on her land would be buried four feet deep, covered with top soil and reseeded. But her climate-friendly, no-till farm has been in her family for 123 years and hasn’t had the soil turned in decades. The pipeline digging, she said, will bring heavy diesel-powered equipment onto her property, and may cause erosion and crop loss for years. .Sherri Webb, who owns 40 acres of farmland in Shelby County, Iowa, says it was worries about losing land to eminent domain that got her involved in the fight against the pipeline. Walker Pickering for The New York TimesMs. Schmidt is fine with climate skepticism. “A key tenet for change,” she said, “is to meet people where they’re at.”Mr. King was first ousted from his committee assignments, then defeated in a primary challenge, after a series of racist comments culminated in an interview with The New York Times in which he asked, “White nationalist, white supremacist, Western civilization — how did that language become offensive?”But Ms. Schmidt said that Mr. King, after 18 years in Congress, remained influential in conservative western Iowa.“I certainly never thought we’d be in a position to have a meeting where you have incredibly liberal socialists teaming with very right-wing QAnon believers,” she continued. “People have to open their minds a little bit, and sometimes they have to shut their mouths.”How Republican presidential candidates respond is, at this point, anyone’s guess. Despite Mr. Trump’s more recent comments, when he was president, his administration said it had no plan to stop the pipelines. In fact, a tax credit created in 2008 to incentivize carbon capture programs like Summit, Navigator and Wolf was expanded by a budget law in 2018 that Mr. Trump signed, and expanded again by a tax bill signed by Mr. Trump in 2020. The credit was expanded yet again by President Biden’s Inflation Reduction Act.Mr. Rastetter has donated around $10,000 to Mr. Trump’s campaigns since 2016, along with the hundreds of thousands he has donated to national and state Republican interests over the past 15 years.Officials at Navigator declined to comment.Critics say Mr. Trump has every reason to oppose the pipeline now. He has called climate change a “hoax” devised by China, so the pipelines are billed as a solution to a problem he does not recognize. Even better, he could use his stated opposition to continue a feud with Ms. Reynolds, whom he has blasted for refusing to endorse him, said Jane Kleeb, a Nebraska Democrat and anti-pipeline activist who has been pressing Mr. Trump to get involved.“There’s no downside for him,” she said.When Mr. Ramaswamy, who has called climate activism a cult, was asked about the issue last month in Davenport, Iowa, he dismissed the pipelines as a solution in search of a problem.But in an interview this week, Mr. Ramaswamy did not blame economic and political interests in Iowa. They are merely responding to incentives set by the federal government, large states like California, and even climate-conscious European nations, he said.“The debate in Iowa is just collateral damage,” he said.Other candidates might have a tougher time threading that needle. The companies backing the pipelines frame them as a salvation for ethanol, which Iowa corn farmers depend on, in a world increasingly hostile to internal combustion engines. One candidate, Gov. Doug Burgum of North Dakota, does not have the luxury of silence. He has already championed the Summit pipeline, which would end in his state, telling The Bismarck Tribune in May that two carbon dioxide pipelines have operated safely in the state for years.“And then now it’s like these are the most dangerous things in the world,” he scoffed.

    German Election: Who Is the Green Party's Annalena Baerbock?

    Annalena Baerbock, the 40-year-old candidate for the Green Party, is likely to have a say in Germany’s next government, no matter who wins this month’s election.BOCHUM, Germany — The woman who wants to replace Chancellor Angela Merkel strode onto the stage in sneakers and a leather jacket, behind her the steel skeleton of a disused coal mining tower, before her a sea of expectant faces. The warm-up act, a guy with an Elvis quiff draped in a rainbow flag, sang “Imagine.”Annalena Baerbock, the Green Party candidate for chancellor, is asking Germans to do just that. To imagine a country powered entirely by renewable energy. To imagine a relatively unknown and untested 40-year-old as their next chancellor. To imagine her party, which has never before run Germany, leading the government after next month’s election.“This election is not just about what happens in the next four years, it’s about our future,” Ms. Baerbock told the crowd, taking her case to a traditional coal region that closed its last mine three years ago.“We need change to preserve what we love and cherish,” she said in this not necessarily hostile, but skeptical, territory. “Change requires courage, and change is on the ballot on Sept. 26.”Just how much change Germans really want after 16 years of Ms. Merkel remains to be seen. The chancellor made herself indispensable by navigating innumerable crises — financial, migrant, populist and pandemic — and solidifying Germany’s leadership on the continent. Other candidates are competing to see who can be most like her.Ms. Baerbock, by contrast, aims to shake up the status quo. She is challenging Germans to deal with the crises that Ms. Merkel has left largely unattended: decarbonizing the powerful automobile sector; weaning the country off coal; rethinking trade relationships with strategic competitors like China and Russia.It is not always an easy sell. In an unusually close race, there is still an outside chance that the Greens will catch up with Germany’s two incumbent parties. But even if they do not, there is almost no combination of parties imaginable in the next coalition government that does not include them. That makes Ms. Baerbock, her ideas and her party of central importance to Germany’s future. But Germans are still getting to know her.“This election is not just about what happens in the next four years, it’s about our future,” Ms. Baerbock said during her election tour.Laetitia Vancon for The New York TimesA crowd gathered to listen to Ms. Baerbock in Duisburg, in western Germany.Laetitia Vancon for The New York TimesA competitive trampolinist in her youth who became a lawmaker at 32 and has two young daughters, Ms. Baerbock bolted onto Germany’s national political scene only three years ago when she was elected one of the Greens’ two leaders. “Annalena Who?” one newspaper asked at the time.After being nominated in April as the Greens’ first-ever chancellor candidate, Ms. Baerbock briefly surged past her rivals in Germany’s long-dominant parties: Armin Laschet, the leader of the Christian Democrats, and Olaf Scholz of the center-left Social Democrats, who now leads the race.But she fell behind after stumbling repeatedly. Rivals accused Ms. Baerbock of plagiarism after revelations that she had failed to attribute certain passages in a recently published book. Imprecise labeling of some of her memberships led to headlines about her padding her résumé.More recently, she and her party failed to seize on the deadly floods that killed more than 180 people in western Germany to energize her campaign, even as the catastrophe catapulted climate change — the Greens’ flagship issue — to the top of the political agenda.Hoping to reset her campaign, Ms. Baerbock, traveling in a bright green double-decker bus covered in solar panels, is taking her pitch to German voters in 45 cities and towns across the country.Ms. Baerbock in the campaign bus with her social media and logistics team.Laetitia Vancon for The New York TimesIt was no coincidence that her first stop was the industrial heartland of Germany, in the western state of North-Rhine Westphalia, which was badly hit by floods this summer and is run by Mr. Laschet, who has been criticized for mismanaging the disaster.“Climate change isn’t something that’s happening far away in other countries, climate change is with us here and now,” Ms. Baerbock told a crowd of a few hundred students, workers and young parents with their children in Bochum.“Rich people will always be able to buy their way out, but most people can’t,” she said. “That’s why climate change and social justice are two sides of the same coin for me.”Leaving the stage with her microphone, Ms. Baerbock then mingled with the audience and took questions on any range of topics — managing schools during the pandemic, cybersecurity — and apologized for her early missteps.“Yes, we’ve made mistakes, and I’m annoyed at myself,” she said. “But I know where I want to go.”Germany’s two traditional mainstream parties have seen their support shrink in recent years, while the Green Party has more than doubled its own.Laetitia Vancon for The New York TimesIf there is one thing that sets Ms. Baerbock apart from her rivals, it is this relative openness and youthful confidence combined with a bold vision. She is the next generation of a Green Party that has come a long way since its founding as a radical “anti-party party” four decades ago.In those early days, opposition, not governing, was the aim.For Ms. Baerbock, “governing is radical.”Her party’s evolution from a fringe protest movement to a serious contender to power in many ways reflects her own biography.Born in 1980, she is as old as her party. When she was a toddler, her parents took her to anti-NATO protests. By the time she joined the Greens as a student in 2005, the party had completed its first stint in government as the junior partner of the Social Democrats. By now, many voters have come to see the Greens as a party that has matured while remaining true to its principles. It is pro-environment, pro-Europe and unapologetically pro-immigration. Ms. Baerbock joined the Greens as a student in 2005.Laetitia Vancon for The New York TimesMs. Baerbock proposes spending 50 billion euros, about $59 billion, in green investments each year for a decade to bankroll Germany’s transformation to a carbon-neutral economy — and paying for it by scrapping the country’s strict balanced budget rule.She would raise taxes on top earners and put tariffs on imports that are not carbon neutral. She envisions solar panels on every rooftop, a world-class electric car industry, a higher minimum wage and climate subsidies for those with low incomes. She wants to team up with the United States to get tough on China and Russia.She is also committed to Germany’s growing diversity — the only candidate who has spoken of the country’s moral responsibility to take in some Afghan refugees, beyond those who helped Western troops. Ms. Baerbock’s ambitions to break taboos at home and abroad — and her rise as a serious challenger of the status quo — is catching voters’ attention as the election nears.It has also made her a target of online disinformation campaigns from the far right and others. A fake nude picture of her has circulated with the caption, “I needed the money.” Fake quotes have her saying she wants to ban all pets to minimize carbon emissions.Ms. Baerbock’s enemies in the mainstream conservative media have not held back either, exploiting every stumble she has made.Many of those who heard her speak in Bochum recently said they were impressed by her confident delivery (she spoke without notes) and willingness to engage with voters in front of rolling cameras.A supporter surprised Ms. Baerbock by offering her a heart-shaped balloon in Hildesheim, in northern Germany.Laetitia Vancon for The New York Times“She focused on issues and not emotions,” said Katharina Münch, a retired teacher. “She seems really solid.” Others were concerned about her young age and lack of experience.“What has she done to run for chancellor?” said Frank Neuer, 29, a sales clerk who had stopped by on his way to work. “I mean, it’s like me running for chancellor.”Political observers say the attacks against Ms. Baerbock have been disproportionate and revealing of a deeper phenomenon. Despite having a female chancellor for almost two decades, women still face tougher scrutiny and sometimes outright sexism in German politics.“My candidacy polarizes in a way that wasn’t imaginable for many women of my age,” Ms. Baerbock said, sitting in a bright wood-paneled cabin on the top level of her campaign bus between stops.“In some ways, what I’ve experienced is similar to what happened in the U.S. when Hillary Clinton ran,” she added. “I stand for renewal, the others stand for the status quo, and of course, those who have an interest in the status quo see my candidacy as a declaration of war.”Bochum was among the stops on Ms. Baerbock’s campaign swing.Laetitia Vancon for The New York TimesWhen Ms. Merkel first ran for office in 2005, at 51, she was routinely described as Chancellor Helmut Kohl’s “girl” and received not just endless commentary on her haircut, but relentless questions about her competence and readiness for office. Even allies in her own party dismissed her as an interim leader at the time.Ms. Baerbock’s answer to such challenges is not to hide her youth or motherhood, but rather to lean into them.“It’s up to me as a mother, up to us as a society, up to us adults to be prepared for the questions of our children: Did you act?” she said. “Did we do everything to secure the climate and with it the freedom of our children?”Ms. Baerbock talking with a group of young women at the end of a campaign day in Duisburg.Laetitia Vancon for The New York TimesChristopher F.

    Germany Floods: Climate Change Moves to Center of Campaign as Toll Mounts

    With more than 160 dead across the region, the receding waters revealed extensive damage as well as deep political divides around how far and fast Germans should go to stem carbon use.BERLIN — With the death toll surpassing 160 and rescue efforts intensifying, the once-in-a-millennium floods that ravaged Germany and much of Western Europe this week had by Saturday thrust the issue of climate change to the center of Germany’s politics and its campaign for pivotal elections this fall that will replace Chancellor Angela Merkel after 16 years in power.The receding floodwaters revealed not only extensive damage — homes wiped away, businesses lost, electricity and sewer systems knocked out and hundreds of vehicles destroyed — but also bitter political divides on climate policy in a week when the European Union rolled out the globe’s most ambitious proposals to cut carbon emissions in the next decade.Though German authorities said it was still too early to place a figure on the damage, its sheer scale shifted the debate from calls not to politicize the catastrophe to the realization that the policies behind it must now play a central role in deciding who will take over leadership after the election on Sept. 26.“The Weather is Political,” Germany’s ARD public television said in its lead editorial on the Friday evening news.“For a long time, chatting about the weather was synonymous with triviality. That’s over now,” it said. “The weather is highly political; there is hardly any nonpolitical weather anymore, especially not during an election campaign.”Residents were clearing mud and unusable furniture from houses on Saturday in Bad Neuenahr, Germany.Thomas Frey/dpa, via Getty ImagesThe death toll in Germany climbed to at least 143 on Saturday, while the toll across the border in Belgium stood at 24, the authorities there said.On Saturday, rescue workers were still sifting through ruin across the region. The German news media was filled with images of homes still submerged in muddy brown water up to the second floor and of bridges reduced to crumbled heaps of stone or tangled metal pylons.Tales of tragedy emerged, as well, perhaps none more poignant than in Sinzig, where neighbors recalled hearing the screams from disabled residents trapped in the waters that gushed into the lower floors of the residential home where a lone night watchman was powerless to save them. The event vividly raised tough questions about whether the authorities had been prepared and why flood warnings were not acted on more aggressively by local officials.More than 90 of those who died in Germany had lived in towns and villages in the valley of the Ahr River in the western state of Rhineland-Palatinate, the police said. Local authorities set up a hotline for citizens in the hard-hit area needing support, whether material or psychological, and issued a call for equipment to help provide basic infrastructure and even clean drinking water.The village of Sinzig, Germany, on Friday.Adam Berry/Getty ImagesMs. Merkel, who turned 67 on Saturday and has said she will leave politics after the election, was expected to visit the district on Sunday to survey the scope of the destruction, her office said. She spoke with the governor of Rhineland-Palatinate by video link on Friday, hours after touching down in Berlin from her trip to Washington.While in the United States, the chancellor and President Biden signed a pact that included a commitment to “taking urgent action to address the climate crisis,” which is to include stronger collaboration “on the policies and energy technologies needed to accelerate the global net-zero transition.”The European Union’s ambitious blueprint, announced Wednesday, is part of plans to make the 27-country bloc carbon-neutral by 2050, and will arguably affect no European country more than Germany, the continent’s largest economy and its industrial powerhouse.Coming a day later, the extensive flooding, which affected Belgium, Switzerland and the Netherlands, in addition to Germany, immediately drew parallels between the calamity and the effects of climate change from environmental activists and wide range of politicians.Chancellor Angela Merkel of Germany and President Biden this week at the White House.Doug Mills/The New York TimesArmin Laschet, 60, the conservative governor of North Rhine-Westphalia, who is looking to succeed Ms. Merkel, has lauded his regional government for passing legislation on climate change, but critics point to the open-pit soft coal mines in the state that are still threatening local villages and his repeated emphasis on the importance of Germany remaining an industrial powerhouse.When pressed on Thursday during an interview on WDR local public television over whether the floods would be a catalyst for him to take a stance toward climate change, Mr. Laschet snapped at the moderator.“I am a governor, not an activist,” he said. “Just because we have had a day like this does not mean we change our politics.”But in 2011, Ms. Merkel did just that.After seeing the nuclear power plant at Fukushima, Japan, melt down after a tsunami hit, the chancellor backtracked on her government’s decision to extend the country’s dependence on nuclear power until 2033. The disaster led her to reset the target shutdown date to 2022, while increasing the amount of energy powered by renewable sources.Floods have a history of influencing political campaigns in Germany. In 2002, pictures of Chancellor Gerhard Schröder wading in rubber boots through streets awash in the muddy waters of the swollen Elbe, while his conservative rival remained on vacation, are credited with helping him win the election that year.Armin Laschet, right, the conservative governor of North Rhine-Westphalia, with President Frank-Walter Steinmeier of Germany, second right, visiting the Erftstadt fire department on Saturday.Pool photo by Marius BeckerPerhaps wary of that lesson, Annalena Baerbock, 40, who is the Greens party candidate for chancellor and Mr. Laschet’s strongest rival, cut short her vacation to visit stricken areas in Rhineland-Palatinate on Friday.She called for immediate assistance for those affected, but also issued an appeal to better protect “residential areas and infrastructure” from extreme weather events, which she linked to the changing climate.“Climate protection is now: In all areas of climate protection, we need to step up our game and take effective climate protection measures with an immediate climate protection program,” Ms. Baerbock said.Whether the flooding will be enough to lift support for the Greens remains to be seen. After enjoying an initial surge of excitement surrounding the announcement of Ms. Baerbock’s campaign — she is the only woman running to replace the country’s first female chancellor — support for the Greens has now dipped to around 20 percent in polls.That puts the party in second place behind Mr. Laschet’s conservatives, who have been climbing to around 30 percent support, the latest surveys show.“In the next two months, there will always be extreme weather events somewhere in the world,” said Thorsten Faas, a political scientist at the Free University in Berlin. “The focus is set after the catastrophe in Rhineland-Palatinate and North Rhine-Westphalia. The topic will determine the election campaign.”Olaf Scholz, 63, Ms. Merkel’s finance minister who is running for the chance to replace her and return his Social Democratic Party to the chancellery, also headed on Friday to flooded regions in Rhineland-Palatinate, where he pledged swift help from the government and linked the disaster to climate change.Workers clearing debris from the streets on Saturday after flooding caused major damage in the village of Schuld.Christof Stache/Agence France-Presse — Getty Images“I am firmly convinced that our task is stopping human-made climate change,” Mr. Scholz told ZDF public television. He praised his party’s role in passing some of Germany’s first climate laws when the Social Democrats governed with the Greens from 1998 to 2005, but called for a stronger effort to move toward a carbon-neutral economy.“What we still have to do now is get all those who have resisted right up to the end that we raise the expansion targets for renewable energies in such a way that it also works out with a CO2-neutral industry to give up this resistance,” he said.While the focus at the moment is on the role that environmental issues will play in the election campaign, questions are also being raised over whether the chancellor, who was a champion for combating climate change going back to 1995, when she presided over the United Nations’ first Climate Conference in Berlin, actually pushed her own country hard enough.Once she came into power, it proved harder to persuade her country’s powerful industrial and automobile lobbies — key supporters of her conservative party — to do their part.The result was legislation that Germany’s highest court ruled in April was not aggressive enough in its attempts to bring down emissions. It ordered the government to strengthen the law to ensure that future generations would be protected.“In recent years, we have not implemented many things in Germany that would have been necessary,” said Malu Dryer, the governor of Rhineland-Palatinate state, said in an interview with the Funke media consortium.She urged German consumers to support climate-neutral products and the country to “show more speed,” adding that climate change is no longer an abstraction. “We are experiencing it firsthand and painfully,” Ms. Dryer said.The city of Bad Münstereifel, Germany, on Friday.Ina Fassbender/Agence France-Presse — Getty ImagesMelissa Eddy More
