During the past decades, the idea of acting to counteract the damage done to the ecosystem by humankind's activities has moved along at least two planning stages.
Fossil fuel companies that want a free pass to keep pumping oil and gas are making wildly unrealistic promises about 'capturing' their emissions at sites of pollution, or removing them from the atmosphere at later date. But the science says drastic emission cuts are needed now if we are to stay within 1.5ºC warming. Thus ‘net zero’ policies are in reality 'not zero', and effectively guarantee that we’ll overshoot 1.5ºC, triggering catastrophic climate impacts which we have no reason to believe can be reversed by speculative and unproven ‘carbon removal’ technologies.
More than half the world’s rivers stop flowing for at least one day per year, according to the first detailed global map of river flow. More rivers than that are expected to run dry if climate change and water management issues aren’t addressed.
