Global CH4 Atmospheric Methane Average 1811ppb(METOP-2)

Continuing the global CH4 methane average jump, on August 13, 2013 am, 0-12 hr, we hit a new high average of 1811 ppb. A comment at Arctic Sea Ice Forum notes: “Assumed methane emissions for the RCP scenarios; which clearly shows that we are now exceeding the methane emissions assumed for RCP 8.5; which is…

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…

Arctic Death Spiral – Evolution to July 2013

Published on YouTube Aug 12, 2013: This is a visualization of the Arctic Death Spiral showing the evolution of the volume of sea-ice over time from 1979 to July 2013. Pitch of the notes are proportional to the average sea-ice volume for each month. Spectral filters are derived from the average sea-ice volume for each…

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…

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. http://www.nasa.gov/mission_pages/fires/main/index.html

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…

Increased Methane emissions from summer Monsoon

Eastern Afghanistan and neighbouring Pakistan have been hit by torrential rain, causing floods which have killed at least 80 people. The region has suffered devastating floods during the monsoon period for the past three years. High methane in North Africa, Middle East and South Asia. The upper tropospheric methane continues to build.  The MODIS image…

AGU: Human – induced climate change requires urgent action

Humanity is the major influence on the global climate change observed over the past 50 years. Rapid societal responses can significantly lessen negative outcomes. “Human activities are changing Earth’s climate. At the global level, atmospheric concentrations of carbon dioxide and other heat-trapping greenhouse gases have increased sharply since the Industrial Revolution. Fossil fuel burning dominates…

Methane in the Arctic Circle

Methane In conditions without oxygen, such as at the bottom of a lake orthe sea, decomposition turns organic matter into methane, rather than carbon dioxide. Large increases in methane emissions would be a grave concern, because methane is 25 times moreeffective at warming the planet than carbon dioxide (over a 100 year time scale). Lakes,…
