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

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

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'

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]

Beyond Paris, Part 3: Overshooting Dangerous Warming Likely, But For How Long?

June 11, 2014 by Matthew Stepp

Global Warming and Growing Risk

Solving climate change is an extremely difficult—even monumental—challenge to address. Carbon emissions come from burning fossil fuels and are deeply embedded in the global economy. Turning on the lights, driving vehicles, powering industry, and living a prosperous life all emit carbon.[read more]

Applying Brainpower to Address the Global Sustainability Crisis

The world faces an unprecedented global sustainability crisis. It is caused by various factors, including climate change, the stress on the planet's ecosystems by developed economies, and the drive for economic growth in the developing world.[read more]

Is This Why Heat-Trapping Methane Emissions Are On The Rise?

May 6, 2014 by Joseph Romm

Rise of Methane Emissions

A new international study offers a worrisome answer to the question of why global levels of methane — one of the most potent heat-trapping greenhouse gases — have begun rising again in recent years. The study finds that the rise “likely stems from wetland emissions.”[read more]

Tornadoes, Extreme Weather, And Climate Change

Dangerous Weather and Climate Change

The return of tornado season with a vengeance has people asking again about a possible link to climate change. At the same time, tantalizing new preliminary research finds “some evidence to suggest that tornadoes are, in fact, getting stronger.” I talked to the lead scientist behind that research.[read more]

Sustainable Consumption and the Global Environmental Crisis

April 29, 2014 by Steven Cohen

In a series of discussions on Earth Day, I found myself returning to two 1970s reports: 'The Limits to Growth' and 'Mankind at the Turning Point.' While weak on policy design, they did a good job describing the interconnected set of problems that remain at the heart of the world's environmental crisis.[read more]

Global Warming: It Ought to Be Illegal

Global Warming Effects

The recent MIT article, 'How the ocean reins in global warming,' points out how burying atmospheric heat deep in the ocean delays long-term global warming. Can we be anything but criminally negligent for not acting on this readily apparent knowledge?[read more]
