Richard Alley: The Big Picture on Energy and Climate (2017)

His presentation (3/22/2017), titled “The big picture on energy and climate,” discusses the dynamics of how money, jobs, national security, ethics and the environment influence perceptions and decisions about energy. The presentation was sponsored by several Lycoming College organizations including: Clean Water Institute, Center for Energy and the Future, Outdoor Leadership and Education program, and…

Climate Expert Mike Mann: Understanding Dire Climate Predictions

This 2016 lecture featuring Michael E Mann http://www.meteo.psu.edu/holocene/public_html/Mann/index.php begins with a review of the now-solid evidence for a human influence on the climate of recent decades. Such evidence includes instrumental measurements available for the past two centuries, paleoclimate observations spanning more than a millennium, and comparisons of the predictions from computer models with observed patterns…

Watch Bubbling Alaska Lakes Catch on Fire #Methane

Seeping methane is driving a global warming feedback loop. Some Arctic lakes are starting to look like witches’ cauldrons. The above video shows an increasingly common site in northern latitudes. As global warming heats these areas up, the frozen ground is melting. And when permafrost turns from solid ground to looser mud, it releases gases…

Ice sheet deglaciation and methane emissions, with the scope on Greenland’s melt season

On June 9 2016, Nuuk, the capital of Greenland, reached the warmest temperature ever recorded for the month of June anywhere on the island, 24 degrees Celsius (75 degrees Fahrenheit). An article from NSDIC, published June 22 elaborated on the broader situation: Surface melting on Greenland’s Ice Sheet proceeded at a brisk pace, with three…

NASA: Coolants Contribute to Ozone Depletion and are strong Greenhouse Gases

According to a new NASA study, a class of widely used chemical coolants known as hydrofluorocarbons (HFC), found in refrigerators and in home and automobile air conditioners, contributes to ozone depletion by a small but measurable amount, countering a decades-old assumption. A class of widely used chemical coolants known as hydrofluorocarbons (HFC) contributes to ozone…

On the Influence of Carbonic Acid in the Air Upon the Temperature of the Ground

In 1896, Svante Arrhenius published below study on the greenhouse effect, the required carbon dioxide gas concentrations for change, and temperature variations deriving from mean, and processes in the climate system which draw down CO2, and the effects of CO2 on the climate on geological times, and elaborated on possible timescales of climate change. Arrhenius estimated based on the CO2 levels at…

The Discovery of Abiotic Methane – A New Methane Hydrate Source (News Roundup)

A reservoir of abiotic methane has been discovered in the Arctic Ocean. This means that there is more of the greenhouse gas trapped under the seabed than previously thought.
