Climate Change is the long-term shift in temperatures and weather patterns that result from natural or human causes. Warmer temperatures have a number of impacts that affect people across the globe, from straining agricultural systems and driving wildlife habitat changes to flooding and wildfires that disrupt communities and jeopardize personal safety. These impacts, referred to...

The world’s ocean is a vast reservoir of salt water that covers almost three fourths of Earth’s surface and makes life on the planet possible. It is a vital source of food for many living things and it contributes to the temperature, rainfall, and weather of the continents that surround it. The ocean is a...

The Earth’s climate is changing faster than at any time in history, mostly because of human activities. This change is causing many problems for people, animals and plants. Global warming is caused by the addition of heat-trapping greenhouse gases to the atmosphere. When these gases blanket the Earth, they prevent the sun’s warmth from escaping...

The Ocean is a vast, salt water body that covers three fourths of the Earth’s surface. Oceans are so large and powerful that they influence every other Earth system, including climate and weather. The constant transfer of heat from the equator to the poles drives oceanic and atmospheric circulation—winds, waves, currents, eddies, and more. It’s...

Wildlife is any living thing that lives in nature and is not a domesticated animal or plant. It can include birds, mammals, reptiles, fish, insects, or other invertebrates. Wild animals live in all ecosystems, from deserts to rainforests, and can be found worldwide. Wildlife conservation is a huge global concern, as many animal species are...

Climate Change is a significant and long-term variation in weather conditions — including temperature, precipitation, wind, and oceans — that persists over many decades or more. It’s different from “weather,” which refers to specific local weather events, like rainstorms, drought, heat waves, and tornadoes. Climate change is caused by human activities that increase the amount...

Ocean is a vast body of salt water that covers most of Earth’s surface and contains a rich diversity of living creatures. Oceans are key to our planet’s climate as they absorb and store massive amounts of heat from the Sun, distribute it around the globe and regulate temperature. They are also vital for our...

Wildlife is all living organisms (including animals, plants, fungus and microorganisms) that are naturally occurring in an environment without direct human influence. The term is often used to describe non-domesticated animal species, but it also applies to wild plant and animal communities and habitats. Wildlife includes everything from the giant elephant to the tiny flea...

Climate Change is the long-term average increase in Earth’s temperature caused by human activities. These activities include burning fossil fuels (coal, oil and gas), deforestation, and land-use changes. These activities increase the amount of “heat-trapping” greenhouse gases in the atmosphere, which causes Earth’s surface temperatures to rise. Climate change can also cause sea level to...

The ocean is the enormous body of salt water that covers more than half of our planet. It is the source of most of the world’s oxygen, and it also contains vast stores of energy and minerals. The sea connects the continents and their people, providing important shipping routes for trade and tourism. It is...
