Global Warming Trends
Global Warming as defined by Wikipedia is “the increase in the average temperature of the Earth’s near-surface air and oceans since the mid-twentieth century. Below is a list of various climate changes and trends related to global warming that have been reported from a variety of sources.
According to the Intergovernmental Panel on Climate Change (IPCC), the average global air temperature near the Earth’s surface increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the hundred years ending in 2005.
Climate model projections from the IPCC predict the average global surface temperature to rise 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century.
Global temperatures on both land and sea have increased by 0.75 °C (1.35 °F) relative to the period 1860–1900 according to the Instrumental Temperature Record.
Since 1979, land temperatures have increased about twice as fast as ocean temperatures (0.25 °C per decade against 0.13 °C per decade).
NASA’s Goddard Institute for Space Studies claims that 2005 was the warmest year since reliable and widespread instrumental measurements became available in the late 1800s.
Portions of North America and Europe may actually cool over the next decade according to the Leibniz Institute of Marine Sciences.
Since 1988, CO2 levels in the world’s skies have increased by 9.8 percent, according to the U.S. National Oceanic and Atmospheric Administration.
A 2005 MIT study found that the destructive potential of tropical storms has doubled over the past 30 years
The number of Category 4 and 5 hurricanes has doubled since the 1970’s
Some experts say the flow of ice from glaciers in Greenland has more than doubled over the past decade.

I appreciate your website, but Wikipedia should never be cited for anything, even a definition. Go to the source.

Do you have sources for this claim? According to the National Hurricane Center, you are wrong!
This looks like nothing more than another AGW propaganda site to me.

The source is a study by researchers at the Georgia Institute of Technology and the National Center for Atmospheric
Research. However, everyone has a study to support their point of view. Thanks for the question. This site is meant to stimulate conversation and tries to be objective as possible.

The reason for the Wikipedia links is that it is generally a good starting point. Normally, sources are cited in the articles themselves along with links. But I do agree that primary sources are the best and most reliable. Again though, it’s there to serve as a good starting point.
