Researchers experiment with new building supports to prepare the Arctic for rapid shifts in permafrost and ground stability.
Canada
The Future Hangs in the (Carbon) Balance
A new study suggests that Canada’s boreal forests could absorb more carbon than they release as climate change progresses.
What Caused the Ongoing Flooding on Lake Ontario?
The floodwaters have also affected residents downstream along the Saint Lawrence River. Although politicians quickly blamed regulations, scientists say it was a perfect storm of natural factors.
Ancient Impact May Have Triggered Long-Term Volcanic Eruptions
Scientists revisit Canada’s Sudbury crater in light of new evidence from other planets that suggests an alternative postimpact history.
Ancient Methane Seeps Tell Tale of Sudden Warming
Newly discovered rock mounds left by ancient methane seeps give scientists clues that methane on ancient ocean floor was released by ancient global warming.
Can Meteorite Impacts Disturb a Planet's Magnetic Field?
Such disturbances probably do not occur on our own planet, but evidence for them might still exist elsewhere in the solar system.
Salty Secret Might Aid Carbon Impact of Restored Wetlands
Research on a surprising way rainfall affected the salinity of a boreal peatland might help restorers of such wetlands wrecked by tar sands mining maximize carbon absorption of reclaimed marshes.

Climate Woes Real, Say Most in U.S., Canada, but Differ on Cause
Two new surveys find that although large majorities of Americans and Canadians think that global warming is happening, relatively few of them think humans are causing it.
Small Rivers Could Have Big Impact on Arctic Ocean
The Mackenzie River carries the bulk of freshwater flow from North America's tundra to the North Atlantic. But what about the effects of smaller rivers from Canada's Arctic islands?
