Hittegolven en klimaataanpak: « Ja, il ben boos over politici » vrtnws.be/p.M9Xa4daGp

Met alweer een hete week, slaat Belgische klimaatwetenschapper Jean-Pascal van Ypersele hartenkreet: "Ja, ik ben woedend" | VRT NWS Nieuws

Jean-Pascal van Ypersele, misschien wel de meest vooraanstaande klimaatwetenschapper van ons land, laakt het volgens hem ontoereikende klimaatbeleid. Dat heeft er mee toe geleid dat er in België deze ...

Seminar on the EU's Arctic strategy and Norway's role @jpvanypersele.bsky.social – the Arctic is not just a victim of the climate crisis, but is an early-warning system for the rest of the planet A simple message: to stop global heating, you have to stop the co2 concentration increasing

Fondé en 1960 aux pieds des Rocheuses, le NCAR, financé par le gouvernement fédéral et géré par un consortium d’universités, est une véritable institution, que ce soit pour les prévisions météo locales ou la modélisation de climat au niveau mondial. www.lefigaro.fr/sciences/aux...

Aux États-Unis, l’Administration Trump veut abattre un «pilier» des sciences du climat

L’administration américaine entend démanteler le Centre national de recherche atmosphérique de Boulder, dans le Colorado, une référence mondiale, au prétexte qu’elle est «alarmiste».

The Trump attack on US National Center for Atmospheric Research @ncar-ucar.bsky.social is an attack on human intelligence. If Trump persists it will soon discover that weather and climate share exactly the same physical laws. Shutting off NCAR would hurt the US economy and security #AttackOnScience

CHAPTER 13 Downsizing the National Oceanic and Atmospheric Administration Valerie J. Karplus and Costa Samaras Carnegie Mellon University The National Oceanic and Atmospheric Administration (NOAA) plays a vital role in the United States' ability to anticipate and respond to short- and long-term threats to security, health, and resilience. NOAA is an agency within the Department of Commerce that tracks and predicts changes in weather, climate, coastal lands, and oceans, enabling actions that prevent damage to life and property. From avoiding deaths due to extreme weather, to averting collisions of objects in space, to informing decisions of farmers and fishers, NOAA offices constantly generate trusted, open information that has profound, tangible benefits for people and businesses. NOAA is facing the potential of losing more than 25% of its current $6 billion budget.' Without NOAA, the US economy will be no match for everyday events, and woefully unprepared for climate change. As one of the world's premier weather and climate change research agencies, NOAA provides data, tools, and information to help advance the scientific understanding of climate change and its impacts.? Essential weather data used widely across both the public and private sectors in the US originates with NOAA.' Helping the public and businesses understand how heat,* drought,' floods," sea level rise,' and other hazards are changing can allow communities to better prepare for climate change and manage impacts. However, risk from climate impacts is a combination of how hazards change, if people and infrastructure are in harm's way of these hazards, and how vulnerable these communities are to damages when extreme weather shows up. NOAA connects these concepts and serves as a critical climate resilience agency, enabling communities to assess climate risks and take action.® NOAA provides on-the-ground resources for communities to build up the local workforce and capacity

Shocking! Evicting this very important climate lab from its New York office is the latest act of war against science by the Trump administration. Ultimately, no economy can flourish while neglecting science. This is barbarian. Full solidarity with all GISS personnel! #WarAgainstScience

NASA’s iconic Goddard Institute for Space Studies—home to Jim Hansen and hundreds more scientists, creator of the GISS model and keeper of the global temperature record—has been evicted from its longstanding NYC office above the “Seinfeld” restaurant. Why? The government told them to move out.

This should be in top media headlines everywhere. Humanity clearly moves in the wrong direction: adding more and more thermal insulation around the planet, which is already too warm! It is urgent to decarbonise our economies and ways of life. #ClimateEmergency

Governments of rich countries need to understand that investing money in climate action today will cost much less over time than waiting for the bill that Nature will send us if we continue to mistreat her. COP30 in BĂ©lem will need to deliver much more.
