Climate Scientists Spell Out Stark Danger And Immorality Of Inaction In New Leaked Report

August 29, 2014 by Joseph Romm

Climate Science Report

The message from climate scientists about our ongoing failure to cut carbon pollution: The catastrophic changes in climate that we are voluntarily choosing to impose on our children and grandchildren — and countless generations after them — cannot plausibly be undone for hundreds of years or more.[read more]

10 Reasons Why 2°C Will Be Tough to Achieve

August 13, 2014 by David Hone

A recent story in The Guardian expressed some optimism that “humans will rise to the challenge of climate change”. Ten reasons were given to be hopeful, but not one of them mentioned the climate basics such as a carbon price or carbon capture and storage.[read more]

Why We Need CCS, Part 4: Carbon Negative Solutions

June 30, 2014 by Schalk Cloete

CCS and Carbon Negative Solutions

If climate science proves to be correct and the 450 ppm scenario is confirmed as a global priority in the medium-term future, we will probably require a very large scale deployment of CO2 negative technologies from the middle of this century. According to the IPCC, CCS will play a very important role in this regard.[read more]

2C in our Rear-View Mirror, Geoengineering Dead Ahead

April 25, 2014 by Lou Grinzo

The idea that 2C of warming is a sufficient way to specify a guideline is naive. Just as important is the rate of change, as quick change will ripple through the environment and cause much more ecological disruption than would slow change resulting in the same absolute temperature level.[read more]

Two Degrees Temperature Target is a Fantasy

February 27, 2014 by Rebecca Lutzy

I have been hearing for years from very knowledgeable professors that we, as a global community, are not going to be able to hold warming to the European Union goal of just two degrees of increase. The best models and best possible politics still do not really allow for it.[read more]

Predictions of a Coming Carbon Asset Bubble Overstated

December 16, 2013 by Amy Myers Jaffe
1

The thinking behind the carbon bubble analysis is that up to two thirds of fossil fuel reserves will not be monetized if the world is to remain below the 2 degrees increase in the global temperature that scientists say is the limit before the planet suffers devastating and irreversible damage.[read more]

Early Reductions in Carbon Dioxide Emissions Remain Imperative

December 9, 2013 by Adam Whitmore

Carbon Dioxide Reduction

Many studies have looked at the rates of emissions reduction necessary to meet certain targets, most commonly looking at limiting temperature rise to 2°C. Some recently published analysis takes a complementary perspective.[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]

New Unabated Coal is Not Compatible with Keeping Global Warming Below 2°C

November 19, 2013 by Mark Jaccard

I have written frequently to explain how dramatic expansion of unconventional oil like bitumen in Canada is found by all leading international analysts to be inconsistent with the two degree limit our political leaders promise to strive for. The same is true for any expansion of coal-fired power plants.[read more]

What to Make of COP 19?

November 18, 2013 by David Hone

COP 19 and Usefulness

Despite the wealth of optimistic publications and climate-speak here in Warsaw, the 2°C pathway remains out of reach. Perhaps the two page spread in the front of the COP publication was inserted as a sobering but much needed reminder of how the energy system is actually developing.[read more]

Record Greenhouse Gases: Is 2 Degrees Still Possible?

Greenhouse Gases and Target Temps

The latest Greenhouse Gas Bulletin released last week by the World Meteorological Organization (WMO) revealed that global atmospheric greenhouse gases hit a new record high, rising 2.2 parts-per-million (ppm) from 2011 levels to an average 393.1 ppm in 2012.[read more]

CO2 Emissions Budget Framing Is A Recipe For Delaying Concrete Action

CO2 Budget

The Washington establishment and the media have been mesmerized into inaction by a short-term budget crisis — funding the continued operation of the government. But it is the continued operation of a livable climate that should have their full attention.[read more]

Has the Wall Street Journal Embraced Climate Action And 2°C Warming Target?

September 17, 2013 by Joseph Romm

Warming Target and Climate Action

Could it be that the Wall Street Journal has finally embraced serious climate action? Have they actually endorsed the warming target of 2°C (3.6°F), long embraced by scientists and global leaders who want to avert the worst impacts of climate change?[read more]

Global Temperature Change: Targeting Two Degrees

August 5, 2013 by David Hone

There is now something of a religious fervor around the goal of 2°C, to the extent that it is almost impossible to discuss other trajectories or outcomes. The only contrast that seems possible with 2°C is something that nobody wants, the “do nothing” scenario of 4°C.[read more]
