To fight climate change, countries need to support research, recruit science experts, and help companies develop clean technology through partnerships and government programs. Citizens also play an important role by staying involved in...

Making things like cement, steel, and chemicals uses a lot of energy and is one of the hardest parts of the economy to clean up. A big problem is that about half the energy is wasted as heat, but better factory design and using things...

Burning coal and natural gas to make electricity causes the most pollution globally, but policies like feed-in tariffs and renewable energy standards help encourage the switch to wind and solar. Texas has been successful in growing clean...

One of the best ways to cut pollution from transportation is to make cities easier to walk or bike in and to improve public transit, like Bus Rapid Transit (BRT), which is cheaper than building subways and still very effective. Cities...

Scientists know that greenhouse gases from human activities are warming the Earth and causing major changes in the environment. Dr. Jennifer Francis explains that for thousands of years, Earth’s temperature was mostly stable due to...

California’s cap-and-trade program is seen as the most successful way to put a price on carbon in the world. It uses a market system where companies buy and sell permits to pollute, but there's a minimum price to keep costs from dropping...

Satellite images show how fast the Earth is changing due to things like melting glaciers, wildfires, dams, and growing cities. These changes can affect people’s lives, such as forcing them to move or losing access to water and land....

Mexico's vast capital — Ciudad de México, among the largest cities in the Americas — is under threat from a severe water crisis and vulnerable to disasters like earthquakes. Learn how this city developed and the successes and struggles...

Dhaka, the capital of Bangladesh, is the fastest-growing city in the world, fueled by flooding, poverty, and people seeking jobs. It faces huge challenges like overcrowding, unsafe water, weak government services, and rising threats from...

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...

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...

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...

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,...
