Newly discovered Mesospheric Polar Clouds possible indicator of Global Warming

The Aeronomy of Ice in the Mesosphere (AIM) mission is the first satellite dedicated to the study of noctilucent clouds. Noctilucent clouds, sometimes called Polar Mesospheric Clouds, were first reported in 1885. Forming at altitudes above 50 miles, they are so faint that they can only be seen from the ground in the reflected light…

Each degree of global warming might ultimately raise global sea levels by more than 2 meters

By PIK: 07/15/2013 – Greenhouse gases emitted today will cause sea level to rise for centuries to come. Each degree of global warming is likely to raise sea level by more than 2 meters in the future, a study now published in the Proceedings of the National Academy of Sciences shows. While thermal expansion of…

A Mechanism for Shallow Methane Hydrate Dissociation

I previously looked at the science and commercial usage of Methane Hydrate, at freshwater influx in the Arctic Circle and asked  Does Freshwater Runoff in the Arctic change Ocean Circulation to Unlock Methane Hydrate in the Deep Ocean? This post covers: Identification of possible mechanism which could eventually release vast quantities of shallow Methane Hydrate…

Climate Change Deniers can’t Spin the Truth!

Howard Brown, August 8 2013: In his book, “The Inquisition of Climate Science,” James Lawrence Powell takes a penetrating look at the subject of “my experts are smarter than yours.”

Powell has a Ph.D. in geochemistry and is a scientific and educational heavyweight. Opposition to climate change has reached a point where deniers cherry-pick fragmentary scientific points and use them to produce flawed or misleading arguments to “refute” the findings of reputable climate scientists.

Powell states, “One could go on rebutting each of the remaining denier arguments — and scientists have. But the pattern is the same: the deniers scavenge the work of legitimate scientists to find any discrepant result and, when they discover one, boast that ‘global warming was never a crisis.’ Scientists find new evidence that removes the discrepancy, or discover that it resulted from an error, which they correct, only to have the deniers go on repeating the discredited claim.”

Two cases in point involve Antarctic sea ice and ice ages. Climate deniers take fragmentary information and spin it misleadingly to claim that it demonstrates the reports of climate research scientists are in error or fraudulent. Fortunately, sea ice and ice ages, as reason to contradict climate science assertions, have been examined as “substitutes” for CO2 and have been disproven.

Regarding Antarctic sea ice, deniers note that sea ice is growing, therefore supposedly refuting the claim that the atmosphere is warming. The deniers omit the fact that sea ice is growing because of colder Antarctic ocean currents. Land ice is melting to the tune of 24 cubic miles per year, as measured by gravity sensing satellites. Try to imagine what a cubic mile looks like.

Relative to ice ages cycles, deniers would have us believe the hypothesis of “cyclical behavior” as the “real” cause of climate change (as opposed to the properties of CO2) and produces simple ups and downs as it always has. Not to worry. After all, don’t winter and summer appear alternatively — cold followed by hot, followed by cold, by hot, by cold, etc.?

NASA: Wildfires, Smog – Particulate Matter Will Only Get Worse (August 2013)

August 10, 2013 – NASA Research is showing due to the increase in the earth’s temperature, we can expect to see more wildfires, and fires in areas that normally don’t see fires. NASA scientists talked to The Weather Channel about the latest research.

NASA: Potential Evaporation in North America Through 2100 (August 2013 in HD)

Published on Aug 9, 2013 by NASA: This animation shows the projected increase in potential evaporation through the year 2100, relative to 1980, based on the combined results of multiple climate models. The maximum increase across North America is about 1 mm/day by 2100. This concept, potential evaporation, is a measure of drying potential or…

NASA: The Future of Fires in Perspective to Future Emissions Scenario’s (August 2013)

Published on Aug 8, 2013 by NASA: With climate change, certain areas of the United States, like the great Plains and Upper Midwest, will be at a greater risk of burning by the end of the 21st-century. Areas like the Mountain West that are prone to burning now will see even more fires than they…

Violence + Global Warming – Temp increase of just 2°C can up inter-group conflicts by 50%

(CBS News) A new study found that climate change may cause people to be more violent. The study draws a link between increased rates of domestic violence, assault and other violent crimes and a warming climate and says that aggression can be associated with higher temperatures. Researchers re-analyzed 60 studies from recent decades that look…
