Methane Impact

Last Friday a paper was released that again showed that methane leaks in North America may be greater than previously estimated. The result was another round of debate as to whether natural gas is a suitable ‘bridge fuel’ to a sustainable future.[read more]

Arctic Autumns On Track To Warm A Staggering 23°F, NOAA Warns

February 15, 2014 by Joseph Romm

Arctic Autumns and Warming

“Climate models show carbon emission mitigation could slow Arctic temperature increases.” That is the NOAA’s glass-is-half-full-of-ice headline for a recent new study that finds we are on track for mind-boggling Arctic warming this century.[read more]

Climatologist: When Souped-Up Ocean Warming Ends, Global Temperatures Look Set To Rise Rapidly

Ocean Temps

The last decade was the hottest on record, and 2010 was the warmest year on record, continuing the long-term trend driven by human emissions. Still, in the past ten years, surface temperatures didn’t appear to warm as fast as many had expected.[read more]

Carbon Conversion is Key to Solving Climate Change Problems

Carbon Conversion

In 1990, President George H.W. Bush signed into law an amendment to the Clean Air Act that mandated emissions reductions of the harmful pollutant sulfur dioxide, SO2, from coal-fired power plants. The government did not instruct industry how to achieve the reductions, only that they were required to.[read more]

Hottest Decades

If we keep listening to the anti-science, pro-pollution crowd and their enablers, then eventually people aren’t going to go through this elaborate charade of wondering whether some large rodent in Pennsylvania can predict the weather — the forecast will always be the same, “bloody hot."[read more]

Canadian Arctic Warming Unprecedented In 120,000 Years

February 1, 2014 by Joseph Romm

Arctic Warming and Weather

Recent warming has been unprecedented in speed, scale, and cause. Last year, we reported on a study that found the rate of warming since 1900 is 50 times greater than the rate of cooling in the previous 5000 years, which threatens to destroy the stable climate that enabled civilization.[read more]

Extreme Weather, the Jet Stream, and Global Warming [VIDEO]

Jet Stream and Extreme Weather

With the eastern half of the United States under a deep freeze and the phrase “polar vortex” making the rounds, we circle back around to the discussion of climate vs. weather and get a grasp on how the jet stream works in this video from The Film Archive.[read more]

Global Warming and Responsibility

The climate crisis of the 21st century has been caused largely by just four men, who between them invented machines responsible for the majority of the greenhouse gas emissions generated since the dawning of the industrial age.[read more]

Good for the Planet

The climate problem is real. The objective needs to be to make more and more salaries and more and more livelihoods dependent upon an accelerate progression up the global warming learning curve. This could be the best way to address the problem.[read more]

NOAA: 2013 Fourth Hottest Year on Record

January 24, 2014 by Tom Schueneman

Global Temps

The latest State of the Climate report released by the National Oceanic and Atmospheric Administration (NOAA) indicates that the globally-averaged temperature for 2013 tied as the fourth warmest year since record-keeping began in 1880.[read more]

Research Affirms Climate Impacts Are Already Here

December 18, 2013 by Dan Huber

This year saw the release of three notable reports related to climate science. They paint a clear picture: Global warming is largely caused by human actions, climate change impacts are already occurring, and some future impacts could be catastrophic to communities, businesses and ecosystems.[read more]

350 Or Bust: Scientists Warn Even 2°C Warming Could Lead To Disaster

Warming Targets

Humanity is choosing to destroy a livable climate, warn 18 of the world’s leading climate experts in a new study. Led by James Hansen, they make the strongest case to date for a target of 350 parts per million (ppm) of CO2 in the air, or about 1°C (1.8°F) total warming.[read more]

Is a Carbon Tax a Sensible Alternative to Subsidies?

December 4, 2013 by Cutter Rolles

Governments around the world stimulate the development of renewables by offering subsidies. But fossil fuels are subsidized too. Given the realities of climate change and increasing global energy demand, a better option could be a carbon tax – which might promote renewables better than any policy.[read more]
