25.07.2022 - Unraveling the interconnections between air pollutants and climate change
In June 1991, Mount Pinatubo in the Philippines erupted for nine hours, ejecting volcanic ash, water vapor, and at least 15 to 20 million tons of noxious sulfur dioxide gas into the stratosphere. Within two hours, the gas transformed into tiny sulfate mists or aerosols that formed bright clouds. Those clouds spread across the entire Earth and persisted for a year, effectively reducing global temperatures by 0.4 to 0.5 degrees Celsius between 1992 and 1993. Once these cooling aerosols fell out of the stratosphere two years later, global temperatures rose again.

22.07.2022 - Battered by climate change, Latin America must brace for worse: report
Floods, heat waves and the longest drought in 1,000 years: Latin America is grappling with devastating climate change impacts that will only get worse, a World Meteorological Organization report warned Friday.

21.07.2022 - Big Oil V the World review – how can these climate crisis deniers sleep at night?
Al Gore described it as “in many ways the most serious crime of the post-world war two era, whose consequences are almost unimaginable”. Can you guess which one the former vice-president meant? Genocide in the former Yugoslavia? Genocide in Rwanda? The attack on the twin towers? The oxymoronic “war on terror” that produced – rather than eliminated – terrorism? The nuclear arms race? The invasion of Ukraine? The crimes of Stalin, Mao, or Pol Pot? Or other ones I haven’t the space to cite?

21.07.2022 - Climate change and land-use changes increase likelihood of flood events
The German government estimates the total losses resulting from the disastrous floods in July 2021 at 32 billion euros. In two studies, one of which is currently available in Natural Hazards and Earth System Sciences, researchers at Karlsruhe Institute of Technology (KIT) have investigated how precipitation, evaporation processes, water flow, and runoff led to this flooding. To improve future preparedness for such extreme events, they advise that risk assessments take greater account of the landscape and river courses, how they change, and how sediments are transported. In addition, projections show an increase in the spatial extent and frequency of such extreme events, as well as higher amounts of precipitation.

20.07.2022 - UK weather turmoil spurs calls to adapt to climate change
Britain's record-breaking heatwave has spurred calls for the government to speed up efforts to adapt to a changing climate, especially after wildfires created the busiest day for London firefighters since bombs rained down on the city during World War II.

19.07.2022 - Glacial microclimates mimic climate change
A cool pocket climate around the snout of a glacier could help researchers predict how forests will respond to fast climate change, according to the authors of a new 120-year case study of a rapidly advancing and retreating glacier in Alaska.
