Two billion people, one-quarter of the world’s population, will be living outside the safe human climate niche within seven years
On June 12, Bill Blair, federal minister of Emergency Preparedness, said Canada is in the midst of its worst wildfire season in the past 20 years — and it was only mid-June.
In particular, Environment and Climate Change Canada added, the forest fires are “driven mainly by higher temperatures and seasonal dryness associated with a warming climate.”There is growing evidence that climate change is happening more rapidly and its impacts will be more severe than anticipated. This month, his team released a grim report on climate change titled “Global Warming in the Pipeline.”
Specifically, Hansen’s team states: “Under the current geopolitical approach to GHG [greenhouse gas] emissions, global warming will likely pierce the 1.5 degree C ceiling in the 2020s and 2 degrees C before 2050. Impacts on people and nature will accelerate as global warming pumps up hydrologic extremes.”
They conclude that climate change has already put more than 600 million people, or nine per cent of the world’s population, outside the safe human climate niche. They then look at what is likely to happen with our current policies, which lead to around 2.7 degrees C global warming.
