Bad climate news is everywhere. Africa is being hit particularly hard by climate change and extreme weather, impacting lives and livelihoods. We are living in a world that is warming at the fastest rate since records began. Yet, governments have been slow to act.

Le chemin vers la reconnaissance d’un Etat palestinien est encore long et il reste de nombreux obstacles mais quelle est l’alternative ?

Stel je voor dat we zouden nadenken over een zomer die ons dichter bij huis kan brengen, in plaats van verder weg, schrijft MO*columnist Jan Mertens. 'Het weg willen, van hier naar daar, versnelt alleen maar het proces dat ervoor zorgt dat er minder hier en daar overblijft.'

In een zomerreeks met vier bijzondere denkers mocht De Denker der Nederlanden natuurlijk niet ontbreken. Restaurant Samenloop dekte de tafel, en David Van Reybrouck vulde de borden, de glazen en de uren met zijn driegangenmenu van wereld en aarde, de mens en al het levende, macht en tegenkracht.

La recrudescence des feux dans l’ouest du pays, leur intensité et leur temporalité sont directement liées au dérèglement climatique.

Just three decades ago, Kabul’s population was less than 2 million, but the toppling of the Taliban in 2001 led to an influx of migrants, lured by the promise of increased security and economic possibility. As its population grew, so did the demand for water. Kabul relies almost entirely on groundwater, replenished by snow and glacier melt from the nearby Hindu Kush mountains. But years of mismanagement and over-extraction have caused those levels to drop by up to 30 meters over the last decade, according to Mercy Corps.

in January, a group of present and former Republican state officials gathered at a posh resort in Sea Island, Georgia, together with conservative leaders, for a two-day lesson in how to dismantle corporate America’s most ambitious response to climate change. At the Cloister, with its golf courses, tennis courts, and beaches, ESG was denounced as a sinister force undermining free markets and democracy.

For decades, the surface of the polar Southern Ocean (south of 50°S) has been freshening—an expected response to a warming climate. This freshening enhanced upper-ocean stratification, reducing the upward transport of subsurface heat and possibly contributing to sea ice expansion. It also limited the formation of open-ocean polynyas. Using satellite observations, we reveal a marked increase in surface salinity across the circumpolar Southern Ocean since 2015. This shift has weakened upper-ocean stratification, coinciding with a dramatic decline in Antarctic sea ice coverage. Additionally, rising salinity facilitated the reemergence of the Maud Rise polynya in the Weddell Sea, a phenomenon last observed in the mid-1970s.

Terug van weggeweest? Het publieke debat over klimaat, smelten van de hitte, experten op praatprogramma’s. Klimaatangst bij veel jonge mensen ebt echter niet periodiek weg, maar kruipt net in de kleren en sluimert al jaren. Maar we moeten beseffen dat net die angst een breekbare luxe is in een wereld vol onzekerheid.

Heatwaves can lead to considerable impacts on societal and natural systems. Accurate simulation of their response to warming is important for adaptation to potential climate futures. Here, we quantify changes of extreme temperatures worldwide over recent decades. We find an emergence of hotspots where the hottest temperatures are warming significantly faster than more moderate temperatures. In these regions, trends are largely underestimated in climate model simulations. Globally aggregated, we find that models struggle with both ends of the trend distribution, with positive trends being underestimated most, while moderate trends are well reproduced. Our findings highlight the need to better understand and model extreme heat and to rapidly mitigate greenhouse gas emissions to avoid further harm.
