🌊 Global Coral Bleaching Crisis
The world is experiencing the most severe coral bleaching event on record, with over 80% of reefs across 82 countries affected due to unprecedented ocean heat levels. Even previously resilient areas like Raja Ampat and the Gulf of Eilat have succumbed. Scientists are urging immediate action to curb fossil fuel use and accelerate clean energy adoption.
🔥 Wildfire Warnings in UK National Parks
UK national parks have issued urgent warnings about a "catastrophic" risk of wildfires over the Easter period due to unusually dry and warm spring weather. Despite some recent rain, park rangers from areas such as the South Downs, North York Moors, and the Highlands report extremely dry conditions caused by one of the driest Marches in decades and above-average April temperatures.
🦋 U.S. Butterfly Populations in Decline
A new study finds that U.S. butterflies are disappearing at drastic rates, with one in five gone since 2000. The popular, fluttering insects have declined by 22% in the last 20 years, highlighting significant biodiversity loss.

Tragédie u evropských břehů: Tanker plný chemikálií v plamenech, desítky obětí
Dnes ráno došlo u pobřeží východní Anglie k obrovské katastrofě. Tanker převážející nebezpečné chemikálie se srazil s kontejnerovou lodí, což způsobilo mohutný požár. Na místě jsou desítky mrtvých a mnoho zraněných.
Záchranáři se okamžitě vydali na místo nehody. Letadla, vrtulníky a záchranné lodě se snaží dostat situaci pod kontrolu. Oheň se ale stále šíří a toxické látky unikají do moře.
Hrozba pro životní prostředí
Chemikálie na palubě tankeru představují vážné riziko pro mořský ekosystém. Odborníci varují, že dopady mohou být srovnatelné s haváriemi z minulosti, kdy podobné úniky zdevastovaly celé oblasti. Pobřežní hlídky sledují situaci a snaží se zabránit nejhoršímu.
Co bylo příčinou?
Zatím není jasné, co přesně vedlo k nehodě. Může jít o navigační chybu, špatnou viditelnost nebo technické selhání. Vyšetřovatelé analyzují záznamy z lodí, aby zjistili, co se stalo.
Co bude dál?
Evropské úřady už zahájily krizová opatření. Británie vyhlásila v oblasti stav nouze a připravuje se na možné ekologické dopady. Situace je stále kritická a vývoj ukáže, jak rozsáhlé budou následky této tragédie.
