Gases in Earth's atmosphere trap the energy from the sun near Earth's surface. This is called the “greenhouse effect” because the gases act like a greenhouse by keeping Earth warm.
About 75% of greenhouse gases released as a result of human activities in the past 20 years are from burning fossil fuels.
Climate change refers to general changes in climate patterns, which includes temperature, precipitation, winds, and many other things.
2005 was the warmest year ever recorded, closely followed by 1998 and 2007. Twelve of the 13 warmest years on record were between 1995 and 2007.
Climate is average weather. It’s what all the weather adds up to over time, to give averages for temperature, rainfall, snow and frost.
The difference in climate between a warm period and the middle of an ice age is between 4°C and 6°C.
125,000 years ago (during the last warm period between ice ages) temperatures were around 1.5°C higher than they are now.
The world has already warmed 0.74°C over the past 100 years.
The oceans keep New Zealand cooler than the rest of the world. Since 1950 New Zealand has warmed by 0.4°C.
Global warming is the increase of Earth's average surface temperature due to greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.
There are many different opinions on Global warming.
With the start of industry in the 1700s, humans began emitting more fossil fuels from coal, oil, and gas to run our cars, trucks, and factories.
The Natural Resources Defense Council proposed the Clean Air Act to cut power plant emissions by 26 percent in the next 7 years.
In the last century, sea levels rose roughly 7 inches after not having changed noticeably in the previous 2,000 years.
Consequences of global warming include drought, severe hurricanes, massive fires, and melting of the polar caps.
According to the U.S. Global Change Research Program, the temperature in the U.S. has increased by 2 degrees the last 50 years and precipitation by 5 percent.
