Global Warming

Category archives for Global Warming

NOAA has released the data for average global surface temperature for the month of May. The number is 0.87 degrees C (1.57 degrees F) above the 20th century average for their data set. This is the highest value seen for the month of May since 1880, which is the earliest year in the database. The…

This is a press release from the Center for Inquiry: Skeptics Dare Heartland Institute to Take Up $25,000 Climate Challenge A leading science advocacy group is throwing down the gauntlet to the Heartland Institute, a group that claims that global warming stopped in 1998, with a stark, simple challenge: If the 30-year average global land…

How Warm Was May?

Human released greenhouse gas pollution continues to warm the surface of the planet. May was thought to be likely a very very warm month but it turns out to be merely very warm (only one “very”) according to data released this morning. Shockingly, May turned out to be, in the NASA GISS data set, less…

The Problem with terminology There is some confusion about the way we talk about global warming. Most of this confusion arises during the communication of science to the public or to policy makers. Part of this confusion rests within the science itself; There is no meaningful confusion about the nature of global warming or how…

There is no such thing as a “pause” or “hiatus” in global warming. There is, however, variation as the earth’s surface temperature steadily rises as the result of the human release of greenhouse gas pollution. Every now and then that variation results in a period of several years when the rise in global temperature is…

Joe and Mary built a house. They built it on an old flood plain of a small river, though there’d not been a flood in years. This was a 500-year flood plain. Not a very floody flood plain at all. The local zoning code required that for a new house at their location the bottom…

Bad Climate Science Debunked

Recently, a paper published in a Chinese journal of science by Monckton, Soon and Legates attracted a small amount of attention by claiming that climate science models “run hot” and therefore overrepresent the level of global warming caused by human greenhouse gas pollution. The way they approached the problem of climate change was odd. The…

The Earth is warming because of what humans have been doing to the atmosphere. Global Warming has a lot of effects many of which we’ve discussed here, but the most obvious one is, well, it gets warmer. At present, India is experiencing record breaking heat and people are dying. It is very difficult to say…

Arctic Sea Ice Decline in 2015

The surface ice in the Arctic has been melting to historic low levels every year for the last several years. The graph above shows the first ten years in the National Snow & Ice Data Center records, meant to indicate what Arctic Sea Ice “normally” does as it melts off during the northern warm months.…

Human released greenhouse gas pollution changes the climatic system through a variety of mechanisms. Trade winds and jet streams change their patterns of movement, and the distribution of moisture in the air changes, with precipitation either lacking more than usual or being more abundant than usual. The patterns of movement of major air masses and…
