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.

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.

Methane is four times more sensitive to global warming than previously thought, a new study shows. The result helps to explain the rapid growth in methane in recent years and suggests that, if left unchecked, methane related warming will escalate in the decades to come.

The growth of this greenhouse gas – which over a 20 year timespan is more than 80 times as potent than carbon dioxide – had been slowing since the turn of the millennium but since 2007 has undergone a rapid rise, with measurements from the US National Oceanic and Atmospheric Administration recording it passing 1,900 parts a billion last year, nearly triple pre-industrial levels.

“What has been particularly puzzling has been the fact that methane emissions have been increasing at even greater rates in the last two years, despite the global pandemic, when anthropogenic sources were assumed to be less significant,” said Simon Redfern, an earth scientist at Nanyang Technological University in Singapore.
