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.
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.
