How does the EPA define climate change?

Definition: The recent and ongoing global average increase in temperature near the Earth’s surface. Global Warming Potential. Definition: A measure of the total energy that a gas absorbs over a particular period of time (usually 100 years), compared to carbon dioxide. Greenhouse Effect.

What are the basics of climate change?

Changing temperature and precipitation patterns. Increases in ocean temperatures, sea level, and acidity. Melting of glaciers and sea ice. Changes in the frequency, intensity, and duration of extreme weather events.

Does CCP care about climate change?

Yes, they do. As the government tries to position itself as an international leader in responding to global warming, recent surveys show that the public supports the government’s actions.

What is the greenhouse effect EPA?

Greenhouse gases keep the Earth warm through a process called the greenhouse effect. Play the video to learn more » The Earth gets energy from the sun in the form of sunlight. The Earth’s surface absorbs some of this energy and heats up.

What are the major types of physical evidence for climate change?

The physical and biological changes that confirm climate warming include the rate of retreat in glaciers around the world, the intensification of rainfall events, changes in the timing of the leafing out of plants and the arrival of spring migrant birds, and shifting of the range of some species.

What is the simplest and most revealing indicator of climate change?

Atmospheric concentrations of carbon dioxide Because the level of greenhouse gases in the atmosphere influences how much energy is trapped in the Earth system, atmospheric concentrations provide a useful indicator of climate change.

What are the 3 indicators of climate change?

Temperatures are rising, snow and rainfall patterns are shifting, and more extreme climate events – like heavy rainstorms and record high temperatures – are already happening.
