The Earth’s climate is changing and we are experiencing more and more extreme events.

Temperatures are increasing, rain and snowfall patterns are shifting.

Many of these changes can be linked to the rising levels of carbon dioxide and other greenhouse gases.

At its core, climate change simply indicates "any significant change in the measures of climate lasting for an extended period of time" (EPA, pre-2017). Global climate change is often spoken of in tandem with global warming, which refers to the recent warming trends in the average temperature of the Earth.

The Greenhouse Effect

Much like the glass of a greenhouse, the Earth's atmosphere keeps heat contained to a level that allows life to flourish. The atmosphere consists of water vapor, nitrogen, oxygen, and trace gases, which include carbon dioxide, methane, and nitrous oxide. The general warming of the planet is being caused by an increase in these trace gases, often called 'greenhouse gases', which then trap increasing amounts of heat. Less of the infrared heat that is emitted by the Earth is able to pass through the atmosphere when these gases are increased, and instead reflect back, warming the Earth's surface more than usual.

Greenhouse Effect

Greenhouse gases are emitted during the burning of fossil fuels (like coal, oil and natural gas). The Environmental Protection Agency has an interactive map showing the  facilities that emit a large amount of greenhouse gases.

Consequences

The changing climate is interfering with natural cycles, causing extreme weather events, rising sea levels1 as glaciers and ice caps melt, and threatening many species with extinction as their environment changes and the oceans become increasingly acidic.
