The world is hurtling towards an era when global concentrations of carbon dioxide never again dip below the 400 parts per million (ppm) milestone, as two important measuring stations sit on the point of no return.

The news comes as one important atmospheric measuring station at Cape Grim in Australia is poised on the verge of 400ppm for the first time. Sitting in a region with stable CO2 concentrations, once that happens, it will never get a reading below 400ppm.

The boreal region stretches across the Northern Hemisphere through Alaska, Canada, Scandinavia and Russia. Boreal forests are increasingly affected by fire and climate change.

Scientists say the near-destruction of Fort McMurray last week by a wildfire is the latest indication that the vital boreal forest is at risk from climate change.

Scientists have been warning for decades that climate change is a threat to the immense tracts of forest that ring the Northern Hemisphere, with rising temperatures, drying trees and earlier melting of snow contributing to a growing number of wildfires.

The near-destruction of a Canadian city last week by a fire that sent almost 90,000 people fleeing for their lives is grim proof that the threat to these vast stands of spruce and other resinous trees, collectively known as the boreal forest, is real. And scientists say a large-scale loss of the forest could have profound consequences for efforts to limit the damage from climate change.

At COP 21 in Paris, Parties to the UNFCCC reached a historic agreement to combat climate change and to accelerate and intensify the actions and investments needed for a sustainable low carbon future.

A new report released by the White House warns that climate change is an imminent and growing threat to public health, and that extreme heat will kill around 27,000 US residents per year by 2100.

A science advisor to the Obama administration by the name of John Holdren commented on the report at a recent press conference, noting that extreme heat waves will make outdoor work periodically “impossible:”

“People who work outdoors will be unable to control their body temperature and will die. This is a really, really big deal.”
