What is the Greenhouse Effect and How Does it Work?

What is the Greenhouse Effect and How Does it Work?

PART OF OUR EDUCATIONAL SERIES 

The greenhouse effect is a naturally occurring process in the earth’s atmosphere that warms the planet. In the absence of a greenhouse effect, the average temperature at the earth’s surface would be approximately 60oF colder.

Won’t Some Warming Benefit Countries that Have a Lot of Cold Weather?

PART OF OUR EDUCATIONAL SERIES 

Some people argue that cold countries are likely to be climate change “winners.” For example, warmer temperatures in Russia could reduce heating fuel consumption, lengthen the agricultural growing season, and open up transportation routes and access to mineral and energy deposits in the Arctic.
