Climate Change refers to a range of changes in the Earth’s climate from local to global scales that have a broad range of impacts on human society and natural ecosystems. These impacts include heat waves, drought, famine, extreme weather events and flooding. The climate is driven by energy from the Sun, aerosols (tiny particles in...

The Ocean covers 70% of the Earth’s surface and is home to countless fish, marine mammals, plants, and birds. It also stores energy (heat) and absorbs carbon dioxide from the atmosphere as it warms up due to climate change. The ocean is an essential part of our planet’s ecosystems and provides many valuable services to...

Wildlife, the animals and plants that live in nature, provides a balance and stability to the natural systems of our planet. It also helps to connect people to their environment and teaches us about the importance of sustaining our planet. Our World Many people depend on wildlife for their food and recreation. Some wildlife species...

Climate Change is a global phenomenon that is having an impact on everything that we value — from food and water to energy, transportation and wildlife. It also affects our health. The planet’s climate is influenced by the energy balance between the sun, the Earth’s surface, and the atmosphere. This balance changes over time as...

Oceans are large bodies of salt water that cover an estimated 70% of Earth’s surface. They are a vital part of our planet’s ecosystem, providing food, minerals, oil, and natural gas. They also help to keep our climate stable by absorbing heat from the Sun and storing energy that can’t be absorbed by the Earth’s...

Wildlife is the term used to describe all of the different animals, birds, fish, fungi, and other organisms that exist in the natural environment without human influence. This includes deserts, forests, rainforests, grasslands and other ecosystems throughout the world. Increasing demand for wildlife and the resulting exploitation of their resources, such as timber, leather goods,...

Climate Change The Earth’s climate is a complex system that depends on the balance of energy from the sun (the source of most of our sunlight) absorbed by the planet and re-emitted as heat. It also depends on the amount of water vapor in the atmosphere and the extent of polar ice sheets. Any disturbance...

The ocean is one of Earth’s largest and most important natural resources. It regulates rainfall and drought, holds 97% of the planet’s water and absorbs carbon dioxide from the atmosphere. It is home to a huge diversity of life and is essential for human health, including food, jobs and recreation. The sea provides a vital...

Wildlife is a term that includes a wide variety of animals, plants and fungi. They can be found in almost all ecosystems, including deserts, woodlands, wetlands, grasslands, and other areas that are usually considered to be wild. A large number of species of animals are threatened with extinction due to habitat loss, climate change and...

Until the early 20th century, natural factors caused atmospheric carbon dioxide concentrations to vary within a range of about 180 to 300 parts per million by volume (ppmv). Since that time, human activities have increased carbon dioxide emission and have risen the Earth’s CO2 concentration to an unprecedented level. Greenhouse gases cause climate change by...
