New Mechanism for Methane Hydrate Dissociation Discovered

Methane hydrates are ice like structures forming a solid similar to ice. Significant amounts have been located under sediments on the ocean floors of the Earth. Generally, methane hydrates are more stable in fresh water than in salt water. A region allowing the formation for methane hydrates (largely dependent on depth and pressure) is called…

Daniel L. Albritton (NOAA) explains 1988 the Greenhouse Effect

On June 29th, 1988, the House Science, Space and Technology subcommittees held a joint hearing on the threat of global warming. Here the segment of Daniel L. Albritton’s (Director Aeronomy Laboratory NOAA) statement. Current Drought and Global Warming https://www.c-span.org/video/?3246-1/current-drought-global-warming D. L.

NASA’s 2018 Permafrost Special “All Hell Breaks Lose”

This week, #NASAExplorers head back in time…by going underground. In the Arctic, a frozen layer of soil – permafrost – trapped dead plants and animals for thousands of years. As the climate warms, that soil is beginning to thaw, releasing carbon dioxide and methane. Release via https://www.youtube.com/watch?v=y7ZbghndiwQ

The 5 Big Climate Unknowns

Climate unknowns include the rate of sea level rise, ozone loss, how the Gulf Stream will react and what it possibly means, the Earth’s response, and the potential for extra methane release from methane clathrates, stored at continental margins. There are many more climate unknowns, for example elaborated in this article https://thinkprogress.org/what-are-the-unknown-unknowns-of-global-warming-1438d934bdee Climate Change Interview…

In Just 10-15 Years World May Hit 2 Degrees of Warming

Back in 2011, a Cornell University research team first made the groundbreaking discovery that leaking methane from the shale gas fracking boom could make burning fracked gas worse for the climate than coal. https://www.desmogblog.com/2018/04/11/climate-change-two-degree-warming-fracking-natural-gas-rush-ingraffea Why a half-degree temperature rise is a big deal https://climate.nasa.gov/news/2458/why-a-half-degree-temperature-rise-is-a-big-deal Paris 1.5-2°C target far from safe, say world-leading scientists http://www.climatecodered.org/2017/07/paris-15-2c-target-far-from-safe-say.html Transcript…

Thousands of little Volcano like Hills form in Arctic!

Scientist speculated that pingos may erupt and lead to the creation of craters – small lakes, thaw ponds. New satellite observations reveal continuous trend.

Permafrost may release largest Mercury source on Earth

There are 32 million gallons worth of mercury, or the equivalent of 50 Olympic swimming pools, trapped in the permafrost. For context, that’s “twice as much mercury as the rest of all soils, the atmosphere, and oceans combined. And it could be released. https://www.washingtonpost.com/news/energy-environment/wp/2018/02/05/the-arctic-is-full-of-toxic-mercury-and-climate-change-is-going-to-release-it   Ambarchik: Research on permafrost at the Siberian arctic coast https://www.youtube.com/watch?v=ZhGcJnRgzy4…

Natural Gas (Methane) likely make Climate much worse

The evidence is overwhelming that natural gas has no net climate benefit on timescales that matters to humans. A new study found that just the methane emissions leaking from New Mexico’s gas and oil industry are equivalent to the climate impact of approximately 12 coal-fired power plants. https://thinkprogress.org/natural-gas-no-climate-benefit-b9118a087875 Natural Gas has Major Role in Climate…
