Planet Earth is covered in water. Ninety-seven percent is in earth’s oceans. Most of the rest is frozen solid — locked up in sea ice and terrestrial ice sheets, glaciers and permafrost. Earth’s cryosphere plays a huge role in regulating climate. As our planet warms, its cryosphere is slowly melting, triggering positive feedbacks that make earth scientists worry.

Long before the ‘intractable conflict’ between Israeli Jews and Palestinians gets resolved, climate change will have thrown everything up for grabs — literally. It already has.
Earth’ surface is one degree warmer today, on average, than it was at the start of the industrial revolution 200 years ago. One degree doesn’t seem like much. The Paris Agreement would limit global temperature rise to two degrees. Sound like a conservative precautionary measure? Perhaps it isn’t.
A mild mid-March in Canada’s notoriously frigid prairie capital cannot be definitively pinned on global climate change. Still, for anyone willing to listen, read and watch, the writing is on the wall. Earth is warming — and fast.

In the summer of 2014, several hundred people gathered at a fracking “Day of Protest” in Kent County, between Moncton and Miramichi — Elsipogtog First Nations territory.
One of Earth’s tens of millions of species has been mining colossal volumes of organic matter buried for ages, and burning the stuff for fuel — raising the surface temperature of their planet to a level higher than any time in the past.
