    U.N. Report on Climate Goals Says Countries Have Made No Progress

    An annual assessment by the world body tracks the gulf between what countries have vowed to do and what they’ve actually achieved.One year after world leaders made a landmark promise to move away from fossil fuels, countries have essentially made no progress in cutting emissions and tackling global warming, according to a United Nations report issued on Thursday.Global greenhouse gas emissions soared to a record 57 gigatons last year and are not on track to decline much, if at all, this decade, the report found. Collectively, nations have been so slow to curtail their use of oil, gas and coal that it now looks unlikely that countries will be able to limit global warming to the levels they agreed to under the 2015 Paris climate agreement.“Another year passed without action means we’re worse off,” said Anne Olhoff, a climate policy expert based in Denmark and a co-author of the assessment, known as the Emissions Gap Report.The report comes a month before diplomats from around the world are scheduled to meet in Baku, Azerbaijan, for annual United Nations climate talks, where countries will discuss how they might step up efforts to address global warming.Lately, those efforts have faced huge obstacles.Even though renewable energy sources like wind and solar are growing rapidly around the world, demand for electricity has been rising even faster, which means countries are still burning more fossil fuels each year. Geopolitical conflicts, from the U.S.-China rivalry to war in places like Ukraine and Gaza, have made international cooperation on climate change harder. And rich countries have failed to keep their financial promises to help poor countries shift away from oil, gas and coal.At last year’s climate talks in Dubai, United Arab Emirates, representatives from nearly every nation approved a pact that called for “transitioning away from fossil fuels” and accelerating climate action this decade. But the agreement was vague on how to do so and on which countries should do what, and so far there has been little follow-through.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Across the World, Diplomats Gird for a Trump Assault on Climate Action

    Some leaders insist that the global clean energy transition will happen with or without the United States.Climate negotiators from Europe, Latin America and some island nations are bracing for the potential return to the world stage of Donald J. Trump, who withdrew the United States from the fight against global warming during his first term.Nations will press forward without the United States if they must, according to climate negotiators who gathered in New York last week during the United Nations General Assembly. But the first Trump presidency was a setback in the climate fight, and a repeat would slow things down at a critical point when scientists say efforts need to speed up.“I don’t want this to happen, of course,” said Laurence Tubiana, who served as France’s climate ambassador during the creation of the 2015 Paris agreement, referring to a potential Trump victory. “But I think there will be a sentiment that we have to double down on the Paris agreement framework. I think everybody’s preparing for that.”The night before Donald J. Trump won the presidency in 2016, an adviser to developing nations in global climate negotiations declared, “No one believes Trump can win, so no real Plan B here!”After he beat Hillary Clinton to win the White House, Mr. Trump kept the world guessing for months about whether the United States would remain a global partner on climate change. Many leaders reserved early judgment, hopeful that people like Mr. Trump’s daughter, Ivanka, would convince him to stay in. They didn’t.Mr. Trump, who has dismissed global warming as a “hoax,” made the United States the first and only country to withdraw from the 2015 Paris agreement that calls on countries to cut the pollution from oil, gas and coal that is dangerously heating the planet. The Trump administration also worked with major oil producers like Saudi Arabia to weaken global pledges around fossil fuels. President Biden rejoined the Paris agreement on his first day in office.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    El cambio climático no es prioritario en la Convención Nacional Republicana

    La plataforma del partido no hace ninguna mención del cambio climático, en cambio, fomenta una mayor producción de petróleo, gas y carbón, que aumentan las temperaturas globales.[Estamos en WhatsApp. Empieza a seguirnos ahora]Este verano, Estados Unidos está experimentando niveles históricos de un calor intenso a causa del cambio climático. Las altas temperaturas han provocado decenas de muertes en el oeste del país, mientras millones de personas sudan debido a los avisos de calor extremo y casi tres cuartas partes de los estadounidenses dicen que el gobierno debe priorizar el calentamiento global.Sin embargo, aunque en el horario estelar del lunes por la noche la energía fue el tema con el que el Partido Republicano inauguró su convención nacional en Milwaukee, el partido no tiene ningún plan para abordar el cambio climático.A pesar de que algunos republicanos ya no niegan el abrumador consenso científico según el cual el planeta se está calentando a causa de la actividad humana, los líderes del partido no lo consideran como un problema que se deba enfrentar.“No sé si hay una estrategia republicana para enfrentar el cambio climático a nivel de organización”, comentó Thomas J. Pyle, presidente de la American Energy Alliance, un grupo de investigación conservador enfocado en la energía. “No creo que el presidente Trump considere imperativo reducir los gases de efecto invernadero por medio del gobierno”.Cuando el expresidente Donald Trump menciona el cambio climático, lo hace en tono de burla.“¿Se imaginan? Este tipo dice que el calentamiento global es la mayor amenaza para nuestro país”, dijo Trump, para referirse al presidente Joe Biden en un mitin en Chesapeake, Virginia, el mes pasado que fue el junio más caluroso que se haya registrado en todo el mundo. “El calentamiento global está bien. De hecho, he oído que hoy va a hacer mucho calor. Está bien”.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

    Rishi Sunak Promises to Honor Britain’s Climate Commitments at COP28 Summit

    Prime Minister Rishi Sunak of Britain rejected claims on Friday that he had lowered his country’s net-zero ambitions and pledged to meet targets in a more pragmatic way.At a news conference, Mr. Sunak, who was spending just a few hours at the COP28 climate summit in Dubai, committed 1.6 billion pounds, or about $2 billion, for international climate finance projects, including for renewable energy and forests, fulfilling a promise to spend a total of £11.6 billion over five years.Mr. Sunak said that Britain was “leading by example” but then added swiftly that excessive costs from the transition to net zero should not be borne by ordinary Britons.“We won’t tackle climate change unless we take people with us,” he said. “Climate politics is close to breaking point.”“The British people care about the environment,” added Mr. Sunak, who has been trailing in opinion polls ahead of an election that is likely to take place next year. “They know that the costs of inaction are intolerable, but they also know that we have choices about how we act. So, yes, we will meet our targets but we will do it in a more pragmatic way which doesn’t burden working people.”Mr. Sunak has recently stressed his determination to limit costs to Britons, whose living standards are being squeezed by inflation as their economy stagnates.That emphasis on Friday from the British prime minister was in striking contrast to the more idealistic tone of King Charles III, a lifelong supporter of environmental causes, who told leaders earlier at the same meeting that “hope of the world” rested on the decisions they took.Britain has been regarded as one of the global leaders in combating climate change, but this year Mr. Sunak signaled a shift in policy when he said he would delay a ban on the sale of gas and diesel cars by five years, and lower targets for replacing gas boilers.That followed a surprise victory in July in a parliamentary election in northwestern London, where his Conservative Party campaigned against moves by the city’s Labour mayor to expand an air-quality initiative that raised fees for drivers of older, more polluting vehicles.On Friday, Mr. Sunak emphasized pragmatism in climate policy even as he insisted that Britain had “done more than others up until now” and would continue to do so.When asked about the brevity of his visit and why he would spend more time in his plane than on the ground in Dubai, Mr. Sunak responded: “I wouldn’t measure our impact here by hours spent. I would measure it by the actual things we are doing.” More

    Your Tuesday Briefing: The U.S. Midterms Loom

    Plus a warning at COP27 and Kherson in distress.Since 1934, nearly every president has lost seats in his first midterm election.Nic Antaya for The New York TimesA U.S. midterms overviewAmericans will finish voting in midterm elections today, which could change the balance of power in state and federal legislative bodies, influence foreign policy and foreshadow the 2024 presidential race.Many races are teetering on a knife’s edge, but Democrats are bracing for losses even in traditionally blue areas. Republican control of the House, Senate or both could embolden the far-right and lawmakers in Washington who traffic in conspiracy theories and falsehoods. Here are four potential election outcomes.Democrats have depicted Republicans as extreme, while Republicans have portrayed Democrats as out of touch on inflation and immigration. Crime is a key issue: Many Americans think there’s a surge in violence, which could benefit Republicans, even though experts disagree on the data.It could also further politicize the U.S. approach to Iran and the war in Ukraine and allow Republicans to slow the torrent of aid to Kyiv. That could benefit Moscow: Russian trolls have stepped up efforts to spread misinformation before the midterms, which researchers say is an attempt to influence the outcome.2024: Donald Trump — who may announce a run soon — and Gov. Ron DeSantis, the top stars of the Republican Party, held competing rallies in Florida. And President Biden, who hoped to heal America’s divides, faces a polarized nation.Cost: These midterms have shattered all spending records for federal and state elections in a nonpresidential year, surpassing $16.7 billion.Many countries and companies have made only halting progress toward previous climate goals.Mohammed Salem/ReutersLosing “the fight of our lives”António Guterres, the U.N. secretary general, gave a stark warning in his opening remarks at yesterday’s COP27 session. “We are in the fight of our lives, and we are losing,” he said. “We are on a highway to climate hell with our foot on the accelerator.”“Loss and damage” — code words for the question of which countries will pay for the effects of climate change — is a key agenda item. Guterres issued an impassioned plea to help Pakistan and other vulnerable countries.The State of the WarKherson Braces for Battle: Civilians and Kremlin-appointed occupation officials have fled the city in southern Ukraine, but Russian troops appear to be digging in for an intense fight. Here’s why control of Kherson matters so much to both sides.Infrastructure Attacks: As they struggle to maintain an electricity grid heavily damaged by Russian missiles, officials in Kyiv say they have begun planning for a once unthinkable possibility: a complete blackout that would force the evacuation of the Ukrainian capital.On the Diplomatic Front: The Group of 7 nations announced that they would work together to rebuild critical infrastructure in Ukraine that has been destroyed by Russia’s military and to defend such sites from further attacks.Refugees: The war has sent the numbers of Ukrainians seeking shelter in Europe soaring, pushing asylum seekers from other conflicts to the end of the line.For the first time, “funding arrangements” for loss and damage were included on the formal agenda of the climate talks, overcoming longstanding objections from the U.S. and the E.U. Costs: On Sunday, the World Meteorological Organization said that the planet had most likely witnessed its warmest eight years on record. And famous glaciers are disappearing.Tactics: Activists want a “fossil fuel nonproliferation treaty.” The U.N. also called for an extension of early warning systems, which could save millions from climate disasters.

An exiled Ukrainian official said that repairs are impossible without specialists and equipment. Volodymyr Zelensky, Ukraine’s president, said that Russia was planning more mass strikes on energy infrastructure.Kherson City is the only regional capital to be captured by Russia, and a battle for its control has loomed for months. Its loss would be a major blow to Moscow, and Ukraine says it has no evidence that Russian forces will abandon the region.Ukraine: The military has reclaimed over 100 towns and villages in the region since it began a counteroffensive in August.Russia: Kremlin-appointed authorities ordered the “evacuation” of all civilians there last month, and occupation officials have reduced their presence. Since then, Russian personnel have shuttered essential services and looted the city, according to residents and Ukrainian officials.Other updates:Russia’s Parliament is poised to pass laws that intensify an L.G.B.T.Q. crackdown.Polls across Europe show a slight dip in popular support for Ukraine, but backing remains strong.THE LATEST NEWSAround the WorldHoward Schultz, the interim chief executive of Starbucks, said that the company was “highly concerned and humbled by the environment.”Valerie Plesch for The New York TimesChief executives seem to think a recession is nigh: Of the 409 S&P 500 companies that have held analyst calls this quarter, the word has come up 165 times.Italy’s hard-right government is taking a harder stand against migrants: Authorities are refusing to let men leave a ship that arrived from Libya.Other Big StoriesMeta is said to be planning the biggest layoffs in its history this week.Jimmy Kimmel will host the Oscars in March.A man in Philadelphia ate 40 chickens in 40 days.

    Your Monday Briefing: COP27 Begins

    Plus India could be key to peace in Ukraine and a child’s death in China sparks new outrage over the zero Covid policy.Only a few people risked outdoor exercise in New Delhi on Thursday.Rajat Gupta/EPA, via ShutterstockCOP27 beginsThe 27th annual U.N. climate talks, known as COP27, began yesterday. At the top of the agenda for developing countries is financing for loss and damage: Who will pay for the costs of a warming world?For them, loss and damage is a matter of justice. They face irreversible destruction and want rich nations — which have emitted half of all heat-trapping gases since 1850 — to compensate them.Wealthy nations blanch at accepting blame. The U.S. and the E.U. fear that such compensation could become an unlimited liability. Last year, wealthy nations vowed to provide $40 billion per year by 2025 to help poorer countries with adaptation, but a U.N. report estimates that this amount is less than one-fifth of what developing nations need.In fact, one frequently cited study estimated that developing countries could suffer between $290 billion to $580 billion in annual climate damages by 2030, even after efforts to adapt. Those costs could rise to $1.7 trillion by 2050.Context: Egypt, the host, and Pakistan, which leads the group of 77 developing nations and is trying to recover from devastating floods, got the issue on the formal agenda for the first time.India: Hundreds of millions of people in the north are suffering from some of the worst air pollution in years. Last week, toxic air prompted school closures and traffic restrictions in New Delhi and beyond.Africa: Gabon, known as Africa’s Eden, is one of the continent’s major oil producers. But it recognizes that fossil fuels won’t last forever. So officials have turned to the rainforest for revenue, while also taking strict measures to preserve it.Russia: World leaders friendly with Vladimir Putin, Russia’s president, have bought Russia’s coal, oil and gas, helping to finance his war and stalling climate progress.S. Jaishankar, India’s foreign minister, is traveling to Russia this week for meetings with Russian officials.Kevin Dietsch/Getty ImagesCould India end Russia’s war?India is trying to take a more muscular role in geopolitics. The country has maintained good relations with both Russia and the West and played a critical role in resolving the grain blockade and in asking Russia to stop shelling Ukraine’s Zaporizhzhia nuclear plant, two major crises.The State of the WarGrain Deal: Russia rejoined an agreement allowing the shipment of Ukrainian grain through the Black Sea, one of the few areas of cooperation amid the war, easing uncertainty over the fate of a deal seen as crucial to preventing famine in other parts of the world.On the Diplomatic Front: The Group of 7 nations announced that they would work together to rebuild critical infrastructure in Ukraine that has been destroyed by Russia’s military and to defend such sites from further attacks.Turning the Tables: With powerful Western weapons and deadly homemade drones, Ukraine now has an artillery advantage in the south, where a battle for the city of Kherson appears to be imminent. The work of reconnaissance teams penetrating enemy lines has also proven key in breaking Russia’s hold in the territory.Refugees: The war has sent the numbers of Ukrainians seeking shelter in Europe soaring, pushing asylum seekers from other conflicts to the end of the line.Now, diplomats and foreign policy experts are wondering if India could use its unique leverage to broker peace. The country’s foreign minister is traveling to Moscow for meetings with Russian officials on economic and political issues this week. But Ukrainians and Russians don’t yet want to talk.And escalating tensions are testing India’s tightrope act. The country continues to buy Russian oil, angering Ukraine and the West, and has refused to support U.N. resolutions condemning Russia. However, at a September summit, Narendra Modi, India’s prime minister, told Vladimir Putin that “today’s era is not of war.”What’s next: Peacemaking could bring India closer to a long-sought prize — a permanent seat on the U.N.

The case has renewed public scrutiny of the country’s “zero Covid” policy.When the boy’s father got through to the emergency hotline after four tries, the dispatcher told him that because he lived in a “high-risk” area, he could seek only online medical counseling. He was reprimanded by officials for not wearing a mask when he sought help.Carrying his son, he tore down some of the fencing that had been put up around his neighborhood and hailed a cab. Nearly two hours after first calling for help, he got his son to a hospital — less than a 10-minute drive from their home.

    Biden Aims to Bolster U.S. Alliances in Europe, but Challenges Loom

    The good will President Biden brings on his first trip abroad papers over lingering doubts about U.S. reliability and the cost that Europe will be expected to pay.WASHINGTON — It should not be that hard to be an American leader visiting Europe for the first time after President Donald J. Trump.But President Biden will face his own challenges when he departs on Wednesday, especially as the United States confronts a disruptive Russia and a rising China while trying to reassemble and rally the shaken Western alliance as it emerges from the coronavirus pandemic.Mr. Biden, who will arrive for a series of summit meetings buoyed by a successful vaccination program and a rebounding economy, will spend the next week making the case that America is back and ready to lead the West anew in what he calls an existential collision between democracies and autocracies.On the agenda are meetings in Britain with leaders of the Group of 7 nations, followed by visits to NATO and the European Union. On Mr. Biden’s final day, in Geneva, he will hold his first meeting as president with President Vladimir V. Putin of Russia.Mr. Biden’s overarching task is to deliver the diplomatic serenity that eluded such gatherings during four years in which Mr. Trump scorched longstanding relationships with close allies, threatened to pull out of NATO and embraced Mr. Putin and other autocrats, admiring their strength.But the good will Mr. Biden brings simply by not being Mr. Trump papers over lingering doubts about his durability, American reliability and the cost that Europe will be expected to pay. At 78, is Mr. Biden the last gasp of an old-style, internationalist foreign policy? Will Europe bear the cost of what increasingly looks like a new Cold War with Russia? Is it being asked to sign up for a China containment policy? And will Mr. Biden deliver on climate?Those questions will loom as he deals with disagreements over trade, new restrictions on investing in and buying from China and his ever-evolving stance on a natural gas pipeline that will route directly from Russia to Europe, bypassing Ukraine.Throughout, Mr. Biden will face European leaders who are wary of the United States in a way they have not been since 1945 and are wondering where it is headed.“They have seen the state of the Republican Party,” said Barry Pavel, the director of the Scowcroft Center for Strategy and Security at The Atlantic Council. “They’ve seen Jan. 6. They know you could have another president in 2024.”White House officials say that stable American diplomacy is back for good, but of course they cannot offer any guarantees after January 2025. European officials are following the raging political arguments in the United States, and they note that Mr. Trump’s grip on his party is hardly weakening.Days before Mr. Biden’s departure, Republicans in Congress rejected the creation of a bipartisan commission to examine the Capitol riot. Republican lawmakers embrace Mr. Trump’s false claims that the 2020 election was stolen. Democrats are faltering in their efforts to pass sweeping legislation to counter Republican attacks on voting rights at the state level.Through it all, Mr. Trump keeps hinting at a political comeback in four years. “There’s an anxiety about American politics,” said Ian Lesser, a vice president at the German Marshall Fund of the United States. “Simply, what is going to happen in the midterm elections? Whether Trumpism will prove more durable than Mr. Trump. What is coming next in American politics?”If the future of the United States is the long-term concern, how to manage a disruptive Russia is the immediate agenda. No part of the trip will be more charged than a daylong meeting with Mr. Putin.Mr. Biden called for the meeting — the first since Mr. Trump embraced Mr. Putin’s denials of election interference at a summit in Helsinki, Finland, three years ago — despite warnings from human rights activists that doing so would strengthen and embolden the Russian leader. Jake Sullivan, Mr. Biden’s national security adviser, has noted that American presidents met with their Soviet counterparts throughout the Cold War, and their Russian successors afterward. But on Monday, he said Mr. Biden would warn Mr. Putin directly that without a change in behavior, “there will be responses.”Yet veterans of the struggle between Washington and Moscow say disruption is Mr. Putin’s true superpower.President Donald J. Trump embraced the denials of President Vladimir V. Putin of Russia in Helsinki, Finland, in 2018.Doug Mills/The New York Times“Putin doesn’t necessarily want a more stable or predictable relationship,” said Alexander Vershbow, who was an ambassador to Russia under President George W. Bush. “The best case one can hope for is that the two leaders will argue about a lot of things but continue the dialogue.”White House officials say the president has no intention of trying to reset the relationship with Russia. Having called Mr. Putin a “killer” this year, Mr. Biden is cleareyed about his adversary, they said: He regards Mr. Putin more as a hardened mafia boss, ordering hits with the country’s supply of nerve agents, than a national leader.But Mr. Biden is determined to put guardrails on the relationship, seeing out some measure of cooperation, starting with the future of their nuclear arsenals.But there is a dawning awareness in Europe that while Mr. Putin cherishes his growing arsenal, Russia’s nuclear ability is a strategic remnant of an era of superpower conflict. In what Mr. Putin recently called a new Cold War with the United States, the weapons of choice are cyberweapons, ransomware wielded by gangs operating from Russian territory and the ability to shake neighbors like Ukraine by massing troops on the border.Mr. Biden will embrace NATO and Article V of its charter, the section that commits every member of the alliance to consider an armed attack on one as an armed attack on all. But it is less clear what constitutes an armed attack in the modern age: a cyberstrike like the SolarWinds hacking that infiltrated corporate and government networks? The movement of intermediate-range missiles and Russian troops to the border of Ukraine, which is not a NATO member?Mr. Biden’s associates say the key is for him to make clear that he has seen Mr. Putin’s bravado before and that it does not faze him.“Joe Biden is not Donald Trump,” said Thomas E. Donilon, who was a national security adviser to President Barack Obama and whose wife and brother are key aides to Mr. Biden. “You’re not going to have this inexplicable reluctance of a U.S. president to criticize a Russian president who is leading a country that is actively hostile to the United States in so many areas. You won’t have that.”When Mr. Biden defines the current struggle as “a battle between the utility of democracies in the 21st century and autocracies,” though, he appears to be worrying more about China’s appeal as a trading partner and source of technology than Russia’s disruptions. And while Europeans largely do not see China as the kind of rising technological, ideological and military threat that Washington does, it is an argument Mr. Biden is beginning to win.The British are deploying the largest fleet of its Navy warships to the Pacific since the Falklands War, nearly 40 years ago. The idea is to re-establish at least a visiting presence in a region that once was part of its empire, with stops in Singapore, Malaysia, Australia and New Zealand. But at the same time, Prime Minister Boris Johnson has signed on to the effort by Washington — begun by Mr. Trump and accelerated by Mr. Biden — to assure that Huawei, the Chinese telecommunications company, does not win new contracts to install 5G cellular networks in Britain.Some in Europe are following suit, but Mr. Biden’s aides said they felt blindsided last year when the European Union announced an investment agreement with China days before Mr. Biden’s inauguration. It was a reflection of fears that if the continent got sucked into the U.S.-China rivalry, European companies would bear the brunt, starting with the luxury auto industry in Germany.The future of the agreement is unclear, but Mr. Biden is going the other way: Last week he signed an executive order banning Americans from investing in Chinese companies that are linked to the country’s military or ones that sell surveillance technology used to repress dissent or religious minorities, both inside and outside China. But to be effective, the allies would have to join; so far, few have expressed enthusiasm for the effort.Mr. Biden may be able to win over skeptics with his embrace of the goal of combating climate change, even though he will run into questions about whether he is doing enough.Four years ago, at Mr. Trump’s first G7 meeting, six world leaders reaffirmed their commitment to the Paris climate accord while the United States declared it was “not in a position to join the consensus.”Protesters outside the White House in 2017 as Mr. Trump announced his decision to withdraw from the Paris climate accord.Stephen Crowley/The New York TimesMr. Biden is reversing that stance, pledging to cut U.S. emissions 50 percent to 52 percent below 2005 levels by the end of the decade and writing in an op-ed in The Washington Post before the summit that with the United States back at the table, countries “have an opportunity to deliver ambitious progress.”But world leaders said they remained wary of the United States’ willingness to enact serious legislation to tackle its emissions and deliver on financial promises to poorer countries.“They have shown the right approach, not necessarily to the level of magnitude that they could,” said Graça Machel, the former education and culture minister of Mozambique.Key to reaching ambitious climate goals is China, which emits more than the United States, Europe and Japan combined. Peter Betts, the former lead climate negotiator for Britain and the European Union, said the test for Mr. Biden was whether he could lead the G7 countries in a successful pressure campaign.China, he said, “does care what the developing world thinks.”Lisa Friedman More
