As leaders set new climate goals, Biden vows support
PARIS — U. S. Presidentelect Joe Biden pledged Saturday to rejoin the Paris climate accord on the first day of his presidency, as world leaders staged a virtual gathering to celebrate the fifth anniversary of the international pact aimed at curbing global warming.
Heads of state and government from over 70 countries took part in the event — hosted by Britain, France, Italy, Chile and the United Nations — to announce greater efforts in cutting the greenhouse gas emissions that fuel global warming.
The outgoing administration of President Trump, who pulled Washington out of the Paris accord, wasn’t represented at the online gathering. But in a written statement sent shortly before it began, Biden made clear the U. S. was waiting on the sidelines to join again and noted that Washington was key to negotiating the 2015 agreement, which has since been ratified by almost all countries around the world.
“The United States will rejoin the Paris Agreement on day one of my presidency,” he said. “I’ll immediately start working with my counterparts around the world to do all that we possibly can, including by convening the leaders of major economies for a climate summit within my first 100 days in office.”
Biden reiterated his campaign pledge that his administration will set a target of cutting U. S. emissions to net zero “no later than 2050.”
Experts say commitments put forward by the international community in the past five years have already improved the longterm outlook on climate change, making the worstcase scenarios less likely by the end of the century. But wildfires in the Amazon, Australia and America, floods in Bangladesh and East Africa, and record temperatures in the Arctic have highlighted the impact an increase of 1.2 degrees Celsius ( 2.2 Fahrenheit) since preindustrial times is already having on the planet.
“If we don’t change course, we may be headed for a catastrophic temperature rise of more than 3 degrees ( Celsius) this century,” U. N. SecretaryGeneral Antonio Guterres said, urging world leaders to declare a “climate emergency.”
The Paris agreement aims to cap global warming at well under 2 C ( 3.6 F), ideally no more than 1.5 C ( 2.7 F), by the end of the century. Meeting the temperature target will require a phasingout of fossil fuels and better protection for the world’s carbonsoaking forests, wetlands and oceans.
The U. N. chief called the announced U. S. return to the Paris accord “a very important signal.”
“We look forward for a very active U. S. leadership in climate action from now on,” Guterres said. “The United States is the largest economy in the world, it’s absolutely essential for our goals to be reached.”
An agreement Friday by European Union members to beef up the continent’s 2030 targets from 40% to at least 55% compared with 1990 levels was broadly welcomed, though activists said it could have aimed even higher.
China, the world’s biggest emitter, also surprised the world in September by announcing a net zero target of 2060, with emissions peaking by 2030.
The 189 countries that are party to the Paris agreement are required to submit their updated targets to the United Nations by the end of the year. This would normally have occurred at the annual U. N. climate summit, but the event was postponed for a year because of the pandemic. The gathering is now scheduled for Glasgow, Scotland, in November 2021.
