Hydrogen: The Savior of the Shipping Industry
Huge container ships relying on fossil fuels transport all kinds of goods across the ocean, creating a huge climate change impact. But there's a better way to power this transport using, of all things, water.

Cement: A Really Hard Problem
Concrete sucks CO2 out of the atmosphere, but making it initially produces a lot of carbon dioxide as a byproduct. Fortunately, by rethinking the chemistry of cement altogether, we can actually use carbon dioxide to create our concrete...

We've Disrupted the All-Important ‘Ocean Conveyor Belt’
Warming ocean water is weakening a major current system called the Atlantic Meridional Overturning Circulation (AMOC), which helps regulate global weather. Melting ice in Greenland and freshwater from rivers are making the ocean less...

How More Water Vapor is Causing Extreme Weather
As the planet warms, there's more water vapor in the air, which makes storms stronger and causes heavier rain and snow. This extra heat and humidity can also make it dangerous to live in some places, especially at night when bodies can’t...

Category 6 Hurricanes?: How Extreme Jet Streams Are Wreaking Havoc
The Arctic is warming quickly, and this is changing the jet stream—a strong wind high in the sky that affects weather. The jet stream is becoming slower and more wavy, which causes extreme weather to last longer, like very cold winters...

Arctic Warming: A Very Bad Positive Feedback Loop
The oceans are very important in climate change because they take in almost 90% of the heat trapped by greenhouse gases and a lot of carbon dioxide. This makes the oceans warmer and more acidic, which has led to record-low sea ice,...
