Global warming is accelerating

A new study shows with 98% certainty that the rate of global warming is increasing. The 1.5 °C warming threshold could be reached in the coming years, in violation of the Paris Agreement. To prevent global warming of 3 °C, the use of fossil fuels must be phased out immediately. The research by Grant Foster … Read more

The tiger mosquito is on the rise

Chikungunya is an infectious disease that causes, among other things, severe and prolonged joint inflammation. For a long time, we considered chikungunya, malaria, dengue and Zika to be (sub)tropical diseases that posed little threat to Western Europe. But is that still true? Recent research sheds light on whether climate change is bringing these diseases our … Read more

The State of our Climate

At the end of January, De Staat van ons Klimaat (The State of Our Climate), the KNMI’s annual report on the year 2025, was published. The report confirms the continuing trend of warming that began during the Industrial Revolution in the early 19th century. The consequences are serious: extreme weather, drought and flooding, and increased … Read more

Europe’s groundwater is declining – but blaming climate change alone doesn’t do justice to the complexity of the problem

Satellite data show clear declines in water storage across large parts of southern and central Europe over the past two decades, while wetter trends dominate further north. These findings are worrying, policy-relevant and deserving of attention. Jan Verkade But when reporting on such results, precision matters. The recent Guardian … Read more

Climate myth: Winter cold

Trump posted on his ‘Truth Social’ account: “Rarely seen anything like it before. Could the Environmental Insurrectionists please explain – WHATEVER HAPPENED TO GLOBAL WARMING???” He was promptly served … Read more

Past the tipping point for coral reefs

Coral reefs act as climate sensors: since the first bleaching was observed in the 1980s, they have consistently shown the impact of warming and acidification. Overfishing, nutrient pollution and disease have pushed these fragile ecosystems to a critical tipping point, if they have not already passed it. The question is whether recovery is still possible. … Read more

Effective climate communication is all about the source, emotion, and perspective for action.

“Good” climate communication is often thought to consist of accurate facts: whether climate change exists (yes) and whether humans play a major role in it (absolutely). The counterpart is climate misinformation: the deliberate dissemination of incorrect information and misleading ideas about causes, solutions and those responsible. The assumption is that the former leads to more … Read more

Efforts to restore the oceans are gaining momentum

Two years ago, the United Nations General Assembly concluded a historic treaty, the High Seas Treaty, an agreement to protect and preserve the biodiversity of the ‘high seas’ for future sustainable use. The term ‘high seas’ refers to oceans and seas outside territorial waters. If the treaty is properly implemented, it will play a key … Read more
