President Obama announced the first-ever National Climate Plan for the United States in June 2013. Under the plan, the U.S. Environmental Protection Agency (EPA) will set carbon pollution standards for power plants. In September 2013, EPA introduced emissions standards for new power plants and...
WRI analysis shows that Pennsylvania has many opportunities to reduce carbon pollution from its power sector. Pennsylvania actually is in a good position to meet moderately ambitious future emissions standards for existing power plants in the near term by using existing
While leaders in Washington, D.C. grapple with a potential national economic crisis, in Florida, mayors and citizens are taking action—on climate change and sea-level rise, that is. Florida Atlantic University (FAU) will host its second annual Sea Level Rise Summit this week, bringing together national and international experts to discuss the impacts of sea-level rise and storm surge on local and national economies.
Communities across the world continue to experience weather-induced food shortages due to drought, floods, devastating wildfires, and other climate change impacts. This week, the Board of the Green Climate Fund (GCF)is meeting to discuss how the GCF will receive and disburse money through various financial inputs and instruments.
An old Wall Street adage says “the market hates uncertainty.” Well, businesses received an unambiguous message last week with the latest Intergovernmental Panel on Climate Change report.
It’s not every day that several former Heads of State, the leader of the global trade union movement, an organizer of urban slum dwellers, a business leader, and a number of other leaders and advocates all come together on the same page.
But last week it happened. And even more strikingly, it was their common concern about climate change that brought them together.
A diverse group of global leaders launched the Declaration on Climate Justice to highlight the impacts of climate change on world’s most vulnerable people and the urgent need to build a “just transition” to low-carbon and climate-resilient societies. The Declaration outlines the priority actions needed to achieve a climate-just society in the near- and long-terms. (See our backgrounder for more information on the issues raised in the Declaration.)
Yesterday, the Obama Administration released the sixth U.S. Climate Action Report (CAR6) for public review, to be submitted to the United Nations Framework Convention on Climate Change (UNFCCC) in January 2014. The report, which all developed countries are required to complete, outlines U.S. historical and future greenhouse gas (GHG) emissions, actions the country is taking to address climate change, and its vulnerability to climate change impacts. This report follows the President’s recently announced Climate Action Plan, which, as the CAR6 report shows, could enable the United States to meet its international commitment of reducing emissions 17 percent below 2005 levels by 2020—if it acts ambitiously, that is.
However, as the report acknowledges, U.S. government agencies will need to propose new rules and take other steps to implement the Climate Action Plan. CAR6 factors in this uncertainty and shows that implementation of the Climate Action Plan will result in reductions in the range of 14 to 20 percent below 2005 levels by 2020 (not taking into account land use). As WRI found in our report, Can The U.S. Get There From Here?, the Obama Administration can achieve a 17 percent emissions-reduction target only by taking ambitious “go-getter” action.
Now is a good time to reflect on what the United States has done over the past four years and what still needs to happen across the major emissions sources in order meet the national emissions-reduction goal and curb the effects of climate change.
Earlier today, the Intergovernmental Panel on Climate Change (IPCC) released the Summary for Policymakers of Working Group I’s (WGI) portion of the 5th assessment report (AR5) on climate change. The report, focused on the physical science of our climate system, confirms the overwhelming scientific consensus that the world is warming and human activities are responsible. Without immediate action to curb...
EDITOR'S NOTE 11/18/13: After this blog post was published, the IPCC updated its Summary for Policymakers. The figures in this blog post have been updated to reflect new information.
The Intergovernmental Panel on Climate Change’s (IPCC) Fifth Assessment Report (AR5) has delivered an overwhelming consensus that climate change impacts are accelerating, fueled by human-caused emissions. We may have just about 30 years left until the world’s carbon budget is spent if we want a likely chance of limiting warming to 2 degrees C. Breaching this limit would put the world at increased risk of forest fires, coral bleaching, higher sea level rise, and other dangerous impacts.
When Will Our Carbon Budget Run Out?
The international community has adopted a goal for global warming not to rise above 2°C compared to pre-industrial temperatures. Scientists have devoted considerable effort to understanding what magnitude of emissions reductions are necessary to limit warming to this level, as the world faces increasingly dangerous climate change impacts with every degree of warming (see Box 1).
IPCC AR5 summarizes the scientific literature and estimates that cumulative carbon dioxide emissions related to human activities need to be limited to 1 trillion tonnes C (1000 PgC) since the beginning of the industrial revolution if we are to have a likely chance of limiting warming to 2°C. This is “our carbon budget” – the same concept as a checking account. When we’ve spent it all, there’s no more money (and the planet’s overdraft fees will be much more significant than a bank’s small charges for bounced checks).[^1]
