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]

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]

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]

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?

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]

We hear the analogy endlessly: To fix the already unfolding climate change disaster, we need an “Apollo-like effort”, a “man-on-the-moon commitment”. This is a terrible analogy; it’s not just inaccurate, it’s devastatingly inaccurate, to the point of being counterproductive.[read more]

It's Still the Lock-In

We’ve put ourselves in a very deep and nasty hole with our past emissions. Can we get out? Of course. But anyone who tries to tell you that the situation isn’t urgent, or that it will be cheap or easy to save ourselves is probably a liar of the first order.[read more]

OTEC Climate Influence

OTEC uses the temperature difference between cooler deep and warmer surface ocean waters to run a heat engine and produce electricity. Global warming needs to be put on a permanent hiatus at the same time as the world is looking for more energy. OTEC provides both.[read more]
