Human-made global heating caused two in every three heat deaths in Europe during this year’s scorching summer, an early analysis of mortality in 854 big cities has found.Epidemiologists and climate scientists attributed 16,500 out of 24,400 heat deaths from June to August to the extra hot weather brought on by greenhouse gases.
The rapid analysis, which relies on established methods but has not yet been submitted for peer review, found climate breakdown made the cities 2.2C hotter on average, greatly increasing the death toll from dangerously warm weather“The causal chain from fossil fuel burning to rising heat and increased mortality is undeniable,” said Friederike Otto, a climate scientist at Imperial College London and a co-author of the report. “If we had not continued to burn fossil fuels over the last decades, most of the estimated 24,400 people in Europe wouldn’t have died this summer.”

Wildfire smoke is responsible for tens of thousands of deaths each year and will do more harm to U.S. residents by midcentury than any other threat driven by climate change, including extreme heat.That’s the conclusion of a new research paper that provides some of the most extensive modeling of the growing health toll of wildfire smoke on public health in the U.S.
The study, which was published in the journal Nature on Thursday, found that each year, on average, wildfire smoke is causing more than 41,400 excess deaths, or more than would be normally expected without smoke given the demographics of the U.S. That figure is more than twice what was previously recognized in other studies.By midcentury, the study’s authors expect that number to grow by an additional 26,500 to 30,000 deaths as human-caused climate change worsens and the risk of wildfires igniting increases. |

When Climate Week kicks off on Sunday in New York City, it will mark the event’s biggest year yet – with organizers reporting a record number of companies participating and more events than ever to attend.
Almost no one had expected this response in a year that has seen the event’s host country – and the world’s wealthiest – set to a climate-denying agenda of boosting fossil fuels, rolling back pollution regulation and defunding U.S. science and climate action.Organizers of Climate Week even wondered, “Would people show up?” said Climate Group Chief Executive Officer Helen Clarkson.
“Actually, there's huge enthusiasm for it," Clarkson said.
Held alongside the U.N. General Assembly since 2009, this year’s Climate Week showcases more than 1,000 events – including presentations, panel discussions and swanky cocktail parties – hosted by environmental nonprofits, companies and philanthropists hoping to generate deals and discussion around protecting the planet.
