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]

February 1, 2014 by Tom Schueneman

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]


The Four Men Who Caused The Majority Of Global Warming

January 28, 2014 by Robert Wilson

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]

Doing Well by Doing Good by the Planet

January 27, 2014 by Jim Baird

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]

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

December 6, 2013 by Joseph Romm

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]

Are Typhoon Disasters Getting More Common?

November 14, 2013 by Roger Pielke, Jr.

Weather and Evidence

I have recently been engaged in a Twitter debate with Jeff Sachs, of Columbia Earth Institute, about extreme weather events, such as typhoon Haiyan. The lesson here is that if you are going to pick cherries, make sure that the fruit is not a lemon.[read more]

Wind Energy Has Dramatically Cut Global Warming Pollution In The US

October 31, 2013 by Zachary Shahan

As is required by Congress, the Environmental Protection Agency recently released annual greenhouse gas data detailing carbon pollution emissions and trends broken down by industrial sector, greenhouse gas, geographic region, and individual facility.[read more]

We Need to Have an Adult Conversation About Climate Change

October 24, 2013 by Lou Grinzo

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

October 3, 2013 by Lou Grinzo

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]

Arab Summer: Warming-Fueled Drought Helped Spark Syrian Civil War

September 10, 2013 by Joseph Romm

Warming and Syrian Unrest

Warming-worsened drought is causing problems all around the Mediterranean, especially Syria, and it is now increasingly clear that the climate models that had been predicting the countries surrounding the Mediterranean would start to dry out were correct.[read more]

Labor Day 2050: Global Warming And The Coming Collapse Of Labor Productivity

September 3, 2013 by Joseph Romm

Warming and Labor

Here’s a Labor Day review of what we know about the impact that global warming is projected to have on labor productivity: A new NOAA study projects that heat-stress related labor capacity losses will double globally by 2050 with a warming climate.[read more]


OTEC Can Be a Big Global Climate Influence

September 3, 2013 by Jim Baird

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]
