We already know the world’s carbon budget is being exhausted at an alarming pace, but a new scientific assessment reveals just how sobering the picture of the global carbon cycle truly is.
The Global Carbon Project’s (GCP) 2013 report finds that at the precise time emissions reductions are needed most, carbon dioxide (CO2) emissions from burning fossil fuels and producing cement have reached their highest level in human history.
The world of open data welcomed a new platform this summer—WRI’s Climate Analysis Indicators Tool, or CAIT 2.0. The platform offers free online access to global greenhouse gas (GHG) emissions and other climate data, enabling researchers, policymakers, media, and others to download, visualize, and share data for analysis and communications on climate change.
Today we’re pleased to roll out the next iteration of CAIT 2.0, featuring improved functionality and other upgrades. Check out a screencast of how CAIT 2.0 works, or read on to learn about some of the benefits visitors can expect to find.
The UNFCCC negotiations are entering a crucial phase. Negotiators decided nearly two years ago to establish an international climate action agreement “with legal force” by 2015. How this agreement will be structured, though, remains to be seen.
WRI’s new working paper lays out the various options for designing the process for submitting "national offers," countries’ plans to reduce their respective greenhouse gas emissions. It will be critical for negotiators to focus on three key areas: the content of the offers, the timing and process for submitting them, and how they will be reviewed.
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]
Natural gas wells represent a significant source of U.S. greenhouse gas (GHG) emissions, as many of them leak methane, which is more than 20 times more potent than carbon dioxide. But while scientists know that “fugitive methane” is a concern, there’s much uncertainty about the full extent of the problem. A new study from the University of Texas—developed in partnership with the Environmental Defense Fund and nine natural gas production companies (Anadarko, BG Group, Chevron, EnCana, Pioneer, Shell, Southwest, Talisman, ExxonMobil)—sheds some light on this perplexing issue.
International climate action took an encouraging step forward today. President Obama reached agreements with the G-20 and with China to phase down the use of hydrofluorocarbons (HFCs), potent greenhouse gases used in appliances like refrigerators and air conditioners.
As extreme weather events like wildfires, heat waves, downpours, and droughts continue to make headlines in the United States and around the world, many have wondered what their connection is to climate change. A new report sheds some light, firmly drawing correlations between several extreme weather events in 2012 and human-induced warming.
Wading through the vast sea of global greenhouse gas (GHG) emissions data can be a real challenge. To help simplify the process and make such data more accessible, today the World Resources Institute is launching the Climate Analysis Indicators Tool, or CAIT 2.0.
The free, online portal provides data on GHG emissions from 186 countries and all 50 U.S. states, as well as other climate data. CAIT 2.0 allows users to view, sort, visualize, and download data sets for comparative analysis. By providing comprehensive emissions data in an easy-to-use tool, users from government, business, academia, the media, and civil society can more effectively explore, understand, and communicate climate change issues.
Check out a screencast of how CAIT 2.0 works.
A growing number of countries and companies now measure and manage their emissions through greenhouse gas (GHG) inventories. Cities, however, lack a common framework for tracking their own emissions—until now.
Thirty-three cities and communities from around the world started pilot testing the Global Protocol for Community-Scale Greenhouse Gas Emissions Pilot Version 1.0 (GPC Pilot Version 1.0) last month. The GPC represents the first international framework for greenhouse gas accounting for cities. It was launched in May 2012 as a joint initiative among WRI, C40, and ICLEI in collaboration with the World Bank, UN-HABITAT, and UNEP.
