Not so fast: Planting trees might cause warming?
November 20, 2014 03:29 PM - Bristol University
Afforestation (planting trees) to mitigate climate change could cause warming rather than cooling globally due to non-carbon effects of land use change, according to new research from the University of Bristol.
Global land use change and its interaction with the climate system is recognised as an important component of the Intergovernmental Panel on Climate Change (IPCC)’s future climate scenarios.
Abrupt rise in greenhouse gases at end of last ice age may be because of permafrost
November 20, 2014 12:30 PM - Alfred Wegener Institute
One of the most abrupt rises in the carbon dioxide concentration in the atmosphere at the end of the last ice age took place about 14,600 years ago. Ice core data show that the CO2 concentration at that time increased by more than 10 ppm (parts per million, unit of measure for the composition of gases) within 200 years. This CO2 increase, i.e. approx. 0.05 ppm per year, was significantly less than the current rise in atmospheric CO2 of 2-3 ppm in the last decade caused by fossil fuels.
EU Court Rules Against UK For Failure to Tackle Air Pollution
November 19, 2014 11:57 AM - Keith Taylor, MEP, The Ecologist
A landmark judgment by the European Court of Justice compels the UK Government to act as soon as possible to reduce air pollution in British cities, writes Keith Taylor - and a good thing too for our health, safety and wellbeing. But it's not just the UK that benefits: every EU country must also comply with the ruling.
Climate history of western US is more complex than previously thought
November 19, 2014 10:54 AM - Southern Methodist University
The climate 150 million years ago of a large swath of the western United States was more complex than previously known, according to new research from Southern Methodist University, Dallas. It’s been held that the climate during the Jurassic was fairly dry in New Mexico, then gradually transitioned to a wetter climate northward to Montana. But based on new evidence, the theory of a gradual transition from a dry climate to a wetter one during the Jurassic doesn’t tell the whole story, says SMU paleontologist Timothy S. Myers, lead author on the study.
Researchers use social media to track air pollution

University of Wisconsin-Madison computer science researchers have developed a method for using social media posts to estimate air pollution levels with significant accuracy.
Study Tracks Southern Beaufort Sea Polar Bear Population Decline
November 17, 2014 12:30 PM - USGS Newsroom
In a new polar bear study published today, scientists from the United States and Canada found that during the first decade of the 21st century, the number of polar bears in the southern Beaufort Sea experienced a sharp decline of approximately 40 percent. The scientists, led by researchers at the U.S. Geological Survey, found that survival of adult bears and cubs was especially low from 2004 to 2006, when most of the decline occurred.
Obama Announces $3 Billion Pledge to U.N. Climate Fund
November 17, 2014 08:00 AM - RP Siegel, Triple Pundit
Right on the heels of his historic climate agreement with China, President Barack Obama announced a pledge of $3 billion to the United Nations’ thus far underfunded Green Climate Fund. The fund was formally established in 2010 at the U.N. Climate Change conference in Cancun. The purpose of the fund was to redistribute resources between the developed world and the developing world in order to assist developing countries in their effort to adapt to and mitigate the impacts of climate change.
Electric vehicles WILL go mass market. Here's why.
November 16, 2014 08:09 AM - BOB SHETH, Electric Forum
Over the last 100 years there have been a number of attempts from electric vehicle enthusiasts to push them into the mass market. Unfortunately the vast majority of these attempts have failed for a variety of reasons, often out of the control of the market itself, but today we stand in a very different place and electric vehicles will eventually go mass-market. We hereby list five reasons why electric vehicles are here to stay in the longer term: –
There have been enormous leaps in electric vehicle technology over the last 10 years which not only offer greater efficiency but also give the driving public greater confidence. This technology continues to advance at breathtaking speed not only in the area of electric vehicles themselves but also battery technology. In many ways the development of new technologies is putting gasoline vehicles in the shadows and grabbing the headlines.
ENERGY STAR's first multifamily properties announced today
November 13, 2014 08:31 AM - ENERGY STAR
Roughly one-third of the U.S. population lives in the country’s 500,000 multifamily buildings, and they spend $22 billion on energy every year. Until this year, apartment and condo managers lacked the tools to measure how much energy they were wasting and compare their performance nationwide. Meanwhile, energy costs for renters have risen by 20 percent over the past decade.
Today, a new era of savings will be ushered in when the U.S EPA announces the first set of multifamily properties to earn the ENERGY STAR certification. The ENERGY STAR first became available to the sector this September, after a three-year partnership with Fannie Mae to develop the scoring system for multifamily properties.
Groundwater affected by Climate Change
November 12, 2014 07:54 AM - Peter Ruegg, ETH Zurich
Global warming stops at nothing – not even the groundwater, as a new study by researchers from ETH Zurich and KIT reveals: the groundwater’s temperature profiles echo those of the atmosphere, albeit damped and delayed.
