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…

A large portion of the glacial mass in Antarctic, previously thought to be relatively stable, is now understood to be destablizing. This is new research just out in Science. The abstract is pretty clear: Growing evidence has demonstrated the importance of ice shelf buttressing on the inland grounded ice, especially if it is resting on…

The risk of hot and cold weather

A new paper is just out in The Lancet that examines the mortality risk of high and low ambient temperatures. The basic idea is that if it is either to hot or too cold, mortality may increase, possibly with the weather being a factor to augment the effects of other health problems, or as a…
