⚠️ This summer, 16,500 heat-related deaths in Europe were linked to climate change, as reported by the latest study from Imperial College London.
🇪🇺 EU, time to step up climate efforts and adopt a science-based 2040 target!

Before altering the air, microbes oxygenated large swaths of the sea Hundreds of millions of years before oxygen surged in the atmosphere 2.4 billion years ago, swaths of oxygen winked in and out of existence in the ocean.
