Record-Breaking Heat in Alaska Wreaks Havoc on Communities and Ecosystems

Alaska in March is supposed to be cold. Along the north and west coasts, the ocean should be frozen farther than the eye can see. In the state’s interior, rivers should be locked in ice so thick that they double as roads for snowmobiles and trucks. And where I live, near Anchorage in south-central Alaska, the snowpack should be deep enough to support skiing for weeks to come. But this year, a record-breaking heatwave upended norms and had us basking in comfortable—but often unsettling—warmth.

What happens if Earth gets 2°C warmer?

If the world gets warmer by two degrees Celsius, we’re screwed. To prevent that, the United Nations signed the Paris Agreement, an international treaty designed to keep the average global temperature “well below 2°C above pre-industrial levels”…A.K.A. what the Earth was like before factories started spewing greenhouse gases into the air.

HEAT WAVES WILL KEEP ON GROUNDING PLANES

Last month, Phoenix enduring a blistering heat wave, with temperatures so high that airport officials had to cancel dozens of flights. The reason was two-fold. First off, some jet engines risk catching on fire in extreme heat. And when air gets hot, it expands and becomes less dense—so an airplane’s wings can’t generate enough lift to get off the ground. Planes either need to speed up during take-off or use a longer runway.

Six pieces of evidence that prove climate change is real

Climate change is often treated as a political issue, but it shouldn’t be.

The facts are these: The climate of our planet is changing at a pace unlike anything seen in the natural fluctuations traced across geological records, and scientists have overwhelmingly traced this global warming trend to human activity.

CEMENT MIGHT NOT BE AS BAD FOR THE PLANET AS WE THOUGHT

City sidewalks and brick buildings look a little greener today, thanks to new research showing that cement can soak up CO2. That’s not the only good news to come out this week. A team of German scientists engineered photosynthesis to be faster and more efficient. And a team of Americans buried 1,000 tons of carbon pollution underground.
