Biden’s presidency could help reduce global heating by about 0.1C if plans fulfilled, say experts
The election of Joe Biden as president of the US could reduce global heating by about 0.1C, bringing the goals of the Paris agreement “within striking distance”, if his plans are fulfilled, according to a detailed analysis.
Biden’s policy of a target to reach net zero carbon emissions by 2050, and plans for a $1.7tn investment in a green recovery from the Covid crisis, would reduce US emissions in the next 30 years by about 75 gigatonnes of carbon dioxide or its equivalents. Calculations by the Climate Action Tracker show that this reduction would be enough to avoid a temperature rise of about 0.1C by 2100.
The 2015 Paris climate agreement is the first truly global deal to tackle climate change. It commits governments to limit temperature rises to no more than 2C (3.6F) – which scientists say is the threshold of safety, beyond which the effects of global warming are likely to become catastrophic and irreversible – and to pursue efforts to limit the temperature increase to 1.5C. It has been signed by 197 countries. The US is on course to become the only country outside the agreement if it follows through on Donald Trump’s vow to leave.
