CO2 levels on the rise - reach 400 ppm for April in Northern Hemisphere

CO2 Levels Reach and Maintain 400 PPM – A Dubious Milestone in Human History

The World Meteorological Organization reports that, for the first time in human history, atmospheric concentrations of carbon dioxide (CO2) eclipsed 400 parts-per-million (ppm) in the northern hemisphere for the entire month of April.CO2 concentration vary with the seasons, generally reaching their highest level early in the northern hemisphere’s spring before seasonal intake of CO2 from vegetation. The first recording of 400 ppm…

AWEA meet amid soaring growth in wind installation and continued uncertainty regarding leadership in Congress

U.S. Wind Industry Gathers Amid Record-Setting Construction, Market Uncertainty

More wind power capacity is under construction today than at any time in industry history, the AWEA highlights in its Q1 2014 market report, but the outlook is being dimmed by ongoing uncertainty over US energy policy. Upon completion, they’ll generate enough clean, renewable electricity to power the equivalent of approximately 4 million average U.S. homes.

The Port of Los Angeles receives a grant in the EPA's new program for sustainable ports

New Sustainable Ports Program To Reduce Carbon Emissions and Environmental Pollution

Ports are vital to world trade and the US economy. With the new Sustainable Ports initiative, the EPA and stakeholders aim to improve ports’ environmental performance. Hosting the first “Advancing Sustainable Ports Summit” in Washington D.C., the EPA awarded six U.S. ports $4.2 mm in Diesel Emissions Reduction Act grants.

Will the US adapt a national cap and trade program?

EarthTalk: Why No Cap and Trade in the U.S.?

EarthTalk® is a weekly environmental column made available to our readers from the editors of E/The Environmental Magazine Dear EarthTalk: If “cap and trade” has worked so well in Europe for reducing greenhouse gas emissions there, why haven’t we tried something similar here in the U.S.?       – Sandra M., Bern, NC “Cap-and-trade,” whereby big polluters must pay…

2013’s Weather: Yet More Good Reasons To Curtail Greenhouse Gas Emissions

The sixth warmest year on record, 2013’s weather was wild, woolly, and very costly for people, economies, and ecosystems around the world, providing additional evidence of the inter-linkages between anthropogenic greenhouse gas emissions, a warming world and the increasing frequency and intensity of extreme weather events.

CSIRO measuring atmospheric carbon

Video Friday: Monitoring Atmospheric Carbon

Dr. Paul Fraser of the Australian Commonwealth Scientific and Industrial Research Organisation (CSIRO) explains how he and his team monitor atmospheric CO2 concentrations globally. Beginning in 1974, CSIRO was one of the first non-American organization to measure CO2 in the atmosphere. Dr. Fraser explains how scientists isolate isotopes in carbon to determine its source, whether from the natural biosphere or…
