and reported the impacts of climate change around the world. we ve seen deforestation on a vast scale contribute to carbon emissions. and you no longer have to travel to the deserts to see the impact of global temperature rise. the effects of climate change are playing out everywhere. we ve been here 20 years, we ve got a beautiful home, and just look at it. but while its impact can be painfully dramatic, the process that brings countries together to tackle the issue can be painfully slow. there have been moments of triumph, though, in this long negotiation. at the cop in 2015 in paris, 196 countries signed a global treaty agreeing to limit global warming to well below two celsius and to aim for 1.5. that s the threshold scientists agree beyond which the most dangerous impacts of global warming play out. so now it comes down to here in glasgow. to keep that 1.5 celsius target alive, emissions need to halve within the next decade, and to reach net zero,
