Greenhouse gases from cattle, fertilisers, manure and agriculture mean that human activities have turned the land and soil into part of the global warming machine.
The speed at which the climate is changing is outstripping forests’ ability to adapt to drier, hotter conditions across vast swathes of the US and Canada.
Vancouver Agreement on Clean Growth and Climate Change is the most positive signal to date of real change in Canada's approach in dealing with climate change.
Researchers warn that more areas of the world will swelter more often in potentially lethal heatwaves unless greenhouse gas emissions are drastically curtailed.
Damages from extreme events like floods are even more relevant than the mean sea level itself when it comes to the costs of climate impacts for coastal regions.
Researchers predict that the hothouse effect of runaway greenhouse gases would ultimately boil our planet dry and make it incapable of sustaining life.
