Known as “extreme event attribution”, the field has gained momentum, not only in the science world, but also in the media and public imagination. These studies have the power to link the seemingly abstract concept of climate change with personal and tangible experiences of the weather.

Scientists have published more than 400 peer-reviewed studies looking at weather extremes around the world, from wildfires in the US and heatwaves in India and Pakistan to typhoons in Asia and record-breaking rainfall in the UK. The result is mounting evidence that human activity is raising the risk of some types of extreme weather, especially those linked to heat.

Climate-change-denying politicians love to attack the IPCC as alarmist. It pleases the fossil fuel barons who fund them. But if anything, the IPCC has likely underestimated the role climate change is playing in the increase in persistent weather extremes we’ve seen in recent summers.
One of us has collaborated on research investigating how the asymmetric pattern of the warming of Earth’s surface (wherein the polar regions have warmed more than the middle latitudes) alters the behavior of the summer jet stream. Specifically, it favors a tendency for high-amplitude meanders of the jet stream that remain locked in place, leading to highly persistent deep high and low-pressure centers associated, alternately, with extreme heat, drought, wildfire or extreme flooding.

As the high pressure system headed towards the east brought temperatures close to 40°C on Tuesday and Wednesday also to the Low Countries and Germany. On Wednesday (20/07) many cities of Germany reached 40°C with Hamburg reaching 40.1°C, but locally the temperature was even higher. The temperature is 10-12°C higher than normal making this extreme heat really unusual.

For the second month in a row, temperatures in India and Pakistan are abnormally high because of a string of strong and prolonged heat waves — and now another surge is building.

Temperatures have already soared to dangerously high levels. They topped 110 degrees in the Indian capital of Delhi on Thursday and Friday, where pavement melted amid the heat, while several cities broke April records.

The heat has also set ablaze a massive 17 story landfill in New Delhi

The Russian invasion of Ukraine has caused catastrophic loss of life, widespread displacement, and a growing global food crisis.
The conflict has also extensively harmed Ukraine’s natural environment, highlighting the many ways in which war devastates biodiversity and contributes to the climate crisis.
Advocates and organizers within Ukraine have documented hundreds of environmental crimes that together, they argue, warrant the charge of ecocide by international courts. These crimes include attacks on industrial facilities that contaminate groundwater supplies and airways and the deliberate bombing of wildlife refuges and other important ecosystems.
