My Mum and Dad are on holiday in the NE of the USA. They have had days now of smoke filled skies and have struggled to do anything outside. They say it is like standing next to a bonfire, almost apocalyptic. They're considering leaving early as are worried it is damaging to their health.
I just looked into it a bit more and have done some google earthing of North America. There are millions of square miles of forests in Canada. As the climate warms and dries, a lot of this will burn. It looks like these fires and smoke will lead to months of smoke every summer for large parts of North America. America (Trump et al.) are blaming Canada for not 'managing their fires' but the reality is, this is impossible to do at scale. And America has their own issues with over 40,000 forest fires so far this year.
It's all so very depressing to think about. We've really stuffed the world up haven't we? I really fear for the future.
