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.

Humans are filling the world with trash, but not all of our waste is visible to the human eye.

While plastic litter on the beach is easy to spot, microplastics and ‘forever chemicals’ have leached far and wide without our barely noticing.Both forms of pollution are now so ubiquitous in the environment, they are falling with the rain. But while the potential threat of microplastics is a regular point of discussion, some researchers argue the spread of other persistent synthetic compounds is comparatively overlooked.

A team of scientists in Europe are now worried we have crossed a critical line. They argue the presence of forever chemicals in our hydrosphere at values that exceed key guidelines means we have entered an unsafe operating space from which there is practically no return.

The warning comes on the heels of another cautionary paper, which argues the world has breached the safe planetary limit for synthetic chemicals.

Germany saw the addition of 615 MW of new PV capacity in June, according to the latest figures from the Federal Network Agency – the Bundesnetzagentur.

This compares to 548 MW in May this year and 428.5 MW in June 2021. The newly installed solar power generation capacity for the first six months of this year was 3.8 GW. In the same period a year earlier, 2.75 GW of solar capacity was added.

Of the monthly new additions, 364.5 MW was represented by PV installations with a capacity lower than 300 kW, built under the country’s feed-in tariff scheme, while the remaining capacity comes from PV systems selected in auctions for PV systems exceeding 750 kW in size.

The Bhalswa landfill, on the outskirts of Delhi, is an apocalyptic place. A gray mountain of dense, decaying trash rises seventeen stories, stretching over some fifty acres. Broken glass and plastic containers stand in for grass and stones, and plastic bags dangle from spindly trees that grow in the filth. Fifteen miles from the seat of the Indian government, cows rummage for fruit peels and pigs wallow in stagnant water. Thousands of people who live in slums near the mountain’s base work as waste pickers, collecting, sorting, and selling the garbage created by around half of Delhi’s residents.

This March was the hottest on record in India. The same was true for April. On the afternoon of April 26th, Bhalswa caught fire. Dark, toxic fumes spewed into the air, and people living nearby struggled to breathe. By the time firefighters arrived, flames had engulfed much of the landfill. In the past, similar fires had been extinguished within hours or days, but Bhalswa burned for weeks. “The weather poses a big challenge for us,” Atul Garg, the chief of the Delhi Fire Service, said, nine days after the fire began. “Firefighters find it difficult to wear masks and protective gear because of the heat.” A nearby school, blanketed by hazardous smoke, was forced to close. In the end, it took two weeks to extinguish the blaze. The charred bodies of cows and dogs were found in the debris.

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.
