Pacific hurricanes to strengthen as Earth warms
Global warming is heating up the oceans. That is causing waters to warm. As a result, Pacific storms — called typhoons — will become more destructive.

A whale of a journey
The 5,200-kilometer (3,200 mile) journey of Isabela provides a window into the migration patterns of blue whales.

Gulf oil spill: Still poisoning dolphins to crickets
Once the 2010 Deepwater Horizon spill ended, oil continued to harm animals in the Gulf of Mexico. Five years later, it still may not be over, biologists worry.

Scientists Say: Eutrophication
When a body of water is filled with nutrients, algae and plants may take advantage. And their presence isn’t always a good thing.

Glaciers on ice — for now
A rise in emissions of carbon dioxide, a greenhouse gas, isn’t just warming Earth. It also could be delaying the onset of the next global cool-down.

Too hot? Some peaks offer climate migrants lots of land
As mountain climates warm, species may actually gain ground as they migrate up to cooler sites, a new study finds.

Asteroids boiled young Earth’s oceans
At least two asteroids hit Earth 3.3 billion years ago. This superheated the atmosphere, boiled the oceans and shaped how early life evolved.

This is no cold fish!
The opah is the fish closest to the whole-body warm-bloodedness typical of mammals and birds. This trait may give the species an edge in the ocean’s cold depths.

Keeping roofs cooler to cut energy costs
Cool it! A cheap paint-on coating for roofing shingles could help reduce a home’s heating bills and might even trim urban ozone levels, a teen shows.

Pesticides offer bees a risky allure
Honeybees and bumblebees sometimes cannot taste or avoid pesticides called neonicotinoids. And that may expose some of these important pollinators to harm.

Carbon dioxide levels rise fast and high
The buildup of carbon dioxide in the atmosphere is rising faster than at any time since dinosaurs roamed the Earth. The burning of fossil fuels is largely to blame.

Scientists ‘see’ thunder for first time
Scientists have captured the first image of thunder. The map shows the relative strengths of the sound waves emanating from the loud clap.
