The 'Global Calculator': A New Interactive Climate Change Scenario Tool

April 4, 2015 by Roman Kilisek

Climate Change Prediction Tools

A new tool named the “Global Calculator” is designed to interactively raise awareness of climate change impacts. A lack of action on behalf of the international community to implement global mitigation and adaptation strategies is expected to increase the severity of these climate change impacts.[read more]

Springing Eternal: Seven Reasons for Hope on Climate Change

March 26, 2015 by Peter Dykstra

Hope on Climate Change

Let’s look at what’s been happening in climate change action lately, because after years of bitter disappointment, things look different now. Because after years and years of cynicism, I see elements of a sea change in urgency and attitude on climate.[read more]

Energy Quote of the Day: 'Failure to Invest in Climate Solutions ... is Fiscally Unwise'

February 14, 2015 by Edward Dodge

Climate Solution Investment

President Obama’s proposed budget for 2016 invests heavily in his agenda to combat climate change. The proposal would increase the budget of the EPA with an emphasis on enactment of the Clean Power Plan to slash greenhouse gases from existing power plants.[read more]

New Study: Breaches of 'Planetary Boundaries' Jeopardize Environmental Sustainability

January 30, 2015 by Roman Kilisek

Earth Sustainability Limits

Four of nine ‘planetary boundaries’ have now been breached as a result of human activity and not natural variability, says a new research paper published in the journal Science entitled “Planetary boundaries: Guiding human development on a changing planet”.[read more]

The Lowest Cost Renewable Energy Comes With a 2000 Percent Environmental Dividend

January 29, 2015 by Jim Baird

NASA and NOAA have proclaimed that 2014 was the warmest year ever recorded. It was the year also in which scientists identified heat movement into the ocean depths as the reason an atmospheric warming hiatus has existed for the previous 15 years.[read more]

'Hottest Year' Story Obscures Bigger News: Ocean Warming Now Off The Charts

January 27, 2015 by Joseph Romm

Temperature Records and Ocean Heat

The big climate news last week was NOAA and NASA announcing that 2014 was the hottest year on record, breaking the highs of 2005 and 2010. But the bigger story actually got buried: Global warming has continued unabated over the past few years.[read more]

Climate and Global Energy: The Answer Lies After 2050, Probably Not Before

January 15, 2015 by David Hone

Future Energy Planning and Climate Solutions

The global energy system works on timescales of decades rather than years. When considering the changes required in managing the climate issue, the short-to-medium-term takes us to 2050 and the long term is 2100! As such, drawing long term conclusions based on a 2050 outlook raises validity issues.[read more]

'Climate Geoengineering': As Contingency Plan Perhaps the Sharpest Tool in the World's Climate Tool Box

January 14, 2015 by Roman Kilisek

Climate Geoengineering Possibilities

The debate about geoengineering technology is slowly creeping into the mainstream media, as both analysts and commentators seem to increasingly doubt the international community’s ability to agree on a comprehensive and effective international agreement at UNFCCC COP 21 in Paris.[read more]

What We Learned About Climate Change In 2014, In 6 Charts

December 21, 2014 by Joseph Romm

Climate Change in Charts

This year saw a lot of big climate reports, including three by the United Nations Intergovernmental Panel on Climate Change (IPCC). And, as always, we had many important publications from the work of individual scientists. And that means great charts![read more]

Global Impacts with Irreversible Changes [INFOGRAPHIC]

December 9, 2014 by Roman Kilisek

Warming and Changes

Severe weather events wreak havoc around the globe and thus tend to dominate international newspaper headlines. No continent has been spared with the strongest storms swirling both in the Pacific and Atlantic basins, in addition to extreme droughts and massive floods geographically well diversified.[read more]

The Planet Just Had Its Hottest October On Record

November 21, 2014 by Joseph Romm

October Temperature Records

The Japan Meteorological Agency (JMA) reports that last month was the hottest October in more than 120 years of record-keeping. This follows the hottest September, August, June, and March-May in JMA’s records. Projections by NOAA make clear 2014 is increasingly likely to be hottest year on record.[read more]

Why Care About Global Warming?

November 11, 2014 by Henry Auer

It seems that new reports appear with increasing frequency emphasizing the worsening of global warming due to increased accumulation of manmade greenhouse gases in the atmosphere. They show that extreme weather appears to be more severe and frequent than in the past, and will continue to worsen.[read more]

Examining Nuclear Energy as Climate Option, Part I

November 11, 2014 by Suzanne Waldman

The IPCC’s latest report claims that “Climate change is set to inflict severe, widespread, and irreversible impacts” on people and the natural world unless carbon emissions are cut sharply and rapidly. Yet the globe is adding 2% more CO2 emissions to the atmosphere every year. We're going backwards.[read more]

IPCC Scientists Emphasize Immorality Of Inaction By Focusing On 'Irreversible Impacts'

November 6, 2014 by Joseph Romm

The Risk of Climate Inaction


What is the biggest change in the new climate report from the IPCC by the world’s top scientists and governments, compared to the report that was released back in 2007? It can probably be summed up in one very foreboding word: “Irreversible.”[read more]

Climate Change-Related Risks and Costs Exist Today

August 25, 2014 by Roman Kilisek

Climate Change Risk and Cost

The risk categories with climate change need to be distinguished: first, risks based on historical data tend to occur with some degree of frequency and therefore can be expected and accounted for. Second, risks that are utterly unexpected and exhibit sudden changes with negative impacts.[read more]
