Regional climate signals pose new challenges for climate science
#ClimateScience has correctly predicted many aspects of the #climate system and its response to increased atmospheric #CarbonDioxide concentrations. Recently, discrepancies between the real world and our expectations of regional climate changes have emerged, as have disruptive new computational approaches.
What the authors describe as the dominant paradigm or "standard approach" of climate science has been developed over the last 60 years by applying fundamental laws of #physics to the climate system under the assumption that small-scale processes are determined by statistical averages dependent on large scales (parameterization).
As with the evolution of other scientific fields, discrepancies have emerged in climate science with respect to how regional #ClimateChange is evolving. For example, the eastern Tropical #Pacific has cooled contrary to all model predictions. Neither was the increased frequency of blocking weather conditions over #Greenland in summer anticipated.
In particular, discrepancies are accumulating in the tropics where changes in the large-scale tropical circulation are known to grow out of instabilities that occur at small and intermediate scales. These scale-coupling mechanisms do not operate in the current generation of #ClimateModels.
"The challenge for conceptual work will be to identify which physics missing from the standard approach is most important for regional changes, and how to incorporate it," says Stevens.

"Atmospheric rivers (ARs) are narrow, elongated regions of intense atmospheric moisture transport that are responsible for a large proportion of midlatitude extreme precipitation. [...] ARs will intensify due to warmer air’s ability to hold more moisture."
Final Day at The Final Countdown!
The last #nextGEMS #hackathon is wrapping up, and our participants are excited to present the results of their hard work over the past few days. 
A highlight of the day? Some truly stunning #visualizations from the hackathon’s plotting challenge! Congrats to Matthias Aengenheyster for his winning #ICON data visualization. 
What a journey it has been! Thanks to everyone who made this event successful

#ClimateScience has correctly predicted many aspects of global warming.
However, regional #ClimateChange poses a challenge. Discrepancies between the real world & our expectations have emerged. At the same time, disruptive #technologies have become available. 
Tiffany Shaw (U Chicago) & #MPIM director Bjorn Stevens provide an interpretation for the situation 
suggesting the field is evolving & that embracing discrepancies is a key path forward.

Study: The impacts of climate activism
"There is strong evidence that climate activism shifts public opinion and media coverage in a pro-climate direction, but this varies by context and the tactics employed. There is more moderate evidence that activism can pressure policymakers to communicate more about climate change, encourage voters to vote in a more pro-climate direction, and financially pressure carbon-intensive companies."

Can renewable energy survive climate change?
As #droughts reduce #hydropower and #clouds dim #solar output around the world, experts say #meteorology and #ClimateScience must be at the heart of the #energy transition.
Yet, even as the push for renewables gains momentum – driven by cheaper technology and an urgent need to slash carbon emissions – experts are waving cautionary flags: Because renewable energy sources depend on weather conditions, climate change is increasingly dictating, and jeopardizing, renewable energy production.
UN News · Is climate science the next power source for renewable energy?As solar, wind, and hydropower expand, scientists say integrating climate data and forecasting is key to making renewable systems stronger.

"Accelerating Temperature Rise
The Northern Hemisphere temperature was 12.86°C on March 19, 2025, a record daily high and 1.65°C higher than 1979-2000."
"Very high temperature anomalies are forecast over the Arctic Ocean for November 2025. "

"EPA said it is reconsidering the scientific finding that greenhouse gases are a danger to public health. This comes as research shows average global temperatures in 2024 likely rose above a 1.5 degree Celsius threshold that for years has been a red line for climate change."

"Marine heat waves are often overlooked despite their significant role in shaping our climate future. They are closely linked to global warming, as the oceans absorb over 90% of the excess heat generated by greenhouse gas emissions."
World Meteorological Day – March 23
Celebrated every year on March 23, World Meteorological Day commemorates the founding of the World Meteorological Organization (WMO) in 1950. This day recognizes the crucial role of weather, climate, and water data in protecting lives, guiding decisions, and shaping our sustainable future.
