The Great Northern Forests of Canada, Russia and Scandinavia are doomed to destruction due to the most severe expected temperature increases from global warming anywhere on Earth which will turn them to savannah within decades with severe consequences for all life on Earth.

*An extensive review of studies published in the journal Science found that the boreal forest can't migrate north fast enough to outpace the impacts of a changing climate.*

"This forest will convert to a type of savannah."

'feedback loops created by permafrost melt and wildfire destruction represent just a few of the worrisome effects of climate change in the boreal. Boreal forest ecosystems are particularly at risk to the rising temperatures of climate change'.

'Worrisome'!https://t.co/zZNKrRnqoZ

'Boreal forests aren’t just important for the climate. They are also home to over 20,000 species and of these more than 300 species listed in the IUCN Red List.. from woodland caribou in North America, and Blakiston’s fish owl in Russia, to Siberian

'When you add up both the absorption and emission, Canada's forests haven't been a net carbon sink since 2001. Due largely to forest fires and insect infestations, the trees have actually added to..greenhouse gas emissions for each of the past 15

Warming

* Ecosystems severely damaged at +1C
* Abrupt extinction events from +1.25C
* Planet's liveability at risk by +1.5C
* Global crop failure fears +1.75C
* Impacts we can't adapt to +2C
* Hothouse Earth zone? +2.25C
* Survival is hard before +2.5C

+2.5C likely by 2050-2075

Ocean extinctions:

'The first completely global bleaching event was in 1998. That was a wake-up call for people here in Australia, because that was the first time ever that the Great Barrier Reef had bleached.'

99% of tropical corals will be doomed at

Many already endangered species are now at risk of suddenly becoming extinct as extreme events

'going past 1.5C is dicing with the planet's liveability. And the 1.5C temperature "guard rail" could be exceeded in just 12 years, in 2030.'

Or even in the

'Even if warming was limited to 1.5 K, all major producing countries would still face notable warming-induced yield reduction.'

1.5C looks like it could deliver major crises. Risks to crops appear set to grow immensely from
