Study also finds high humidity means people in hundreds of cities are enduring their worst ever heat stress

Scientists have linked extreme weather events like excessive heat, flooding and wildfires to big emitter states’ failure to take urgent climate action despite the dangers posed to the rights of those living there and around the world. Governments worldwide are breaking electoral promises, defying court decisions over their lack of climate action, and ignoring warnings that have been voiced by international bodies for years.

Photosynthesis does not always result in wood growth, a key factor in carbon dioxide sequestration

Modi denied climate change for years. Now, as heat deaths mount, his government offers branding instead of protection.

A climate monster is growing right now in the Pacific Ocean, perhaps the most fearsome El Niño since before scientists even began modeling them. They now know the pattern quite well: A marine heat-wave in the Pacific Ocean scrambles global weather and produces in some places more intense droughts and in others more intense rainfall and flooding; disruptions to hurricane patterns and monsoon seasons, which can cause widespread crop failures; and much more punishing heat.

In a Swiss forest lab, scientists tracked how beech and oak leaves cool themselves and pinpointed the moment heat and drought push them past their limits.

Analysis of six extreme heatwaves found when temperature and humidity were accounted for, all were potentially deadly for older people

Using a field experiment, we measured the heat tolerance of insects across many different groups. This is important because most previous studies either combine inconsistent datasets or focus on a single species. Our goal was to understand how entire insect communities respond to heat. We looked at a large variety of insects, such as flies, bees, beetles, butterflies and grasshoppers, to name just a few. We found that many are likely to face dangerous levels of heat stress. This was true even under conservative assumptions, including the possibility that species move into cooler habitats.

​"Extreme heatwaves like the one impacting the Western US this month are one of the catastrophic disasters these companies predicted their conduct would bring about," said Public Citizen.
