Aerosols are tiny solid or liquid particles suspended in the air.

For the first time, climate scientists have compiled a continuous, high-fidelity record of variations in Earth’s climate extending 66 million years into the past.

Eating less meat and dairy products in favor of plant-based proteins like those found in grains, legumes and nuts could make a huge difference in how much carbon dioxide reaches the atmosphere, research by Oregon State University shows.

Through a unique research collaboration, researchers at the University of Helsinki have exposed major changes taking place in the insect communities of the Arctic. 

The lake in eastern Africa is known for its intense nighttime thunderstorms, which are influenced by the lake's location, size, and nearby topography.

When a hail storm strikes, the damage can be catastrophic for homes, businesses, agriculture and infrastructure.
