Historic CO2 Emissions Require Immediate Cuts

Historic CO2 Emissions Require Immediate Cuts

Two scientists urge the world to start reducing greenhouse emissions right now. There’s no time to be lost, they argue in Nature Climate Change. Future global temperatures depend on how much carbon dioxide has accumulated in the atmosphere, so as emissions increase, so does the rate of warming. The reasoning by Myles Allen, of the University of Ox… Read More

Sea Level Experts Concerned About ‘High-End’ Scenarios

Sea Level Experts Concerned About ‘High-End’ Scenarios

This type of study peels back the curtain on sea level specialists, allowing the public to see their views and giving policy makers the chance to assess various risk management approaches, the study said. The study’s projections overlap, but are generally higher than, the most recent report from the U.N. Intergovernmental Panel on Climate Change (… Read More

Warsaw Talks Ignore IPCC ‘Carbon Budget’ Approach

Warsaw Talks Ignore IPCC ‘Carbon Budget’ Approach

The idea of a finite “carbon budget” — a key part of the U.N. Intergovernmental Panel on Climate Change’s (IPCC) recent assessment of climate change — have been ignored at the ongoing climate talks in Warsaw, which end on Friday, in favor of what some scientists say are piecemeal emissions cuts that are less likely to solve the problem.… Read More

Drought, and not widespread snowstorms, may be the biggest story this winter, according to the official U.S. winter outlook, issued by the National Oceanic and Atmospheric Administration (NOAA) on Thursday. The outlooks shows that the winter of 2013-14 is likely to feature an expansion and intensification of drought conditions across the Southwest … Read More

Scientists, U.N. Official Warn of ‘Unabated’ Coal Use

Scientists, U.N. Official Warn of ‘Unabated’ Coal Use

The scientists’ statement called the Communique “misleading” and said that coal use needs to decline, and any new coal-fired power plants must use carbon capture and storage technologies, also known as CCS, in order for the world to have a realistic chance of meeting the goal of limiting global warming to 3.6°F (2°C) or less, when compared to prein… Read More

Staggered Turbines Harness the Most Wind Power

Staggered Turbines Harness the Most Wind Power

U.S. scientists have worked out how to get 33 percent more power from an offshore wind farm – stagger the turbines rather than line them up in neat, orderly rows. Cristina Archer of the University of Delaware and colleagues report in Geophysical Research Letters that they started with a real, working offshore wind farm – Lillgrund in Sweden – and … Read More

Insurance Shortfall Hits Poorest and Most Vulnerable

Insurance Shortfall Hits Poorest and Most Vulnerable

The Philippines is located at the center of one of the world’s most severe storm regions. Scientists say that climate change is increasing the frequency and ferocity of such events. Yet despite the growing risk to their homes and livelihoods, most of the 96 million Filipinos have no insurance cover. According to insurance brokers in the Philippine… Read More

2013 On Track to be Seventh Warmest Year Since 1850

2013 On Track to be Seventh Warmest Year Since 1850

The WMO report, which was released in Warsaw, Poland, where diplomats are meeting to forge a path forward toward a new global climate treaty in 2015, found that temperatures in 2013 are about the same as the average annual temperature during 2001-2010, which was the warmest decade on record.… Read More
