Describe climate change and its effects
OER Text Material
This subsection starts with Climate Change. It is noted that climate change is the term used to refer to long-term shifts in temperatures due to human activity and, in particular, the release of greenhouse gases into the environment. After defining pollution as what happens when contaminants are introduced into an environment (water, air, land), different types pollutions like water, soil, garbage, air, toxic and radioactive waste pollutions, are explained.

This video is about global warming. It is noted that rising temperature of only one degree can mean the difference between ice and water. Many pictures of melting ice are shown to prove that global warming is real. Climate change takes many surprising ways. Breaking/melting glaciers in parts of Greenland is making the vegetation dry.
This lecture notes that climate change is a defining challenge for the 21st century. It examines the scientific evidence for climate change describing how simulations of the Earths weather and climate are constructed and how these can be used to make assessments of what our climate and weather might be like in the coming decades. It is argued that climate change is one of the defining challenges of the twenty-first century, and how we respond will determine our future prosperity, health and well-being and the sustainability of the Earth’s natural environment.
This article is about the impact of global warming on species. Global warming is likely to be the greatest cause of species extinctions this century. The Intergovernmental Panel on Climate Change says a 1.5°C average rise may put 20-30% of species at risk of extinction. If the planet warms by more than 2°C, most ecosystems will struggle.
This piece by NASA provides evidence that climate change is happening, discusses the causes, the effects, and finally, solutions to climate change.
