It's now described as "extremely likely" that we humans are warming the planet, according to scientists who make up the Intergovernmental Panel on Climate Change. And that's a big and sobering statement coming from what Penn State University's Michael Mann describes as hundreds of "conservative scientists." Mann was previously on the IPCC. The panel is in Stockholm to roll out their fifth big assessment report.
One way to reduce a city’s environmental impact is to cut the number of cars on the roads. Like many cities, Pittsburgh is encouraging people to ride bicycles instead of driving. Cyclists don’t burn fossil fuels, and they don’t produce air pollution. But as more people two-wheel the daily commute, safety has become a serious issue.
In a far-reaching study of fracking in several states, researchers at the University of Texas found greenhouse gas pollution during fracking to be lower than previous EPA estimates. The study re-sets a debate over the relative climate benefits for using natural gas over coal, and provides the largest-to-date amount of field-level data from active drilling sites.
Climate change isn’t something people may want to discuss around the water cooler. So asking people to make changes to curb greenhouse gases can be tough. A new program in Pittsburgh is trying to improve the climate conversation and what people might do about the problem, neighborhood by neighborhood.
It's been a busy week in Marcellus shale development news. Headlines included new data on whether fracking is making people in western Pennsylvania sick, reports about supressed science on fracking, and news about a state official moonlighting as a leasing agent.
Looking for a great book to enjoy during this second half of "those lazy, hazy crazy days of summer"? Douglas Fischer, editor of the Daily Climate website and board member of the Society of Environmental Journalists, suggests some of his favorites about how people and wildlife will fare as the climate changes.
After much anticipation and speculation, President Obama announced his administration's climate plan. A central piece of the plan, and the most controversial element, includes new lower limits for carbon emissions from power plants.
Michael Levi, the David M. Rubenstein senior fellow for energy and the environment at the Council on Foreign Relations, recently released a new book titled The Power Surge, which provides significant insight into his thoughts on energy and climate.
The world’s climate odometer just crossed one of those big, round numbers. For the first time in human history, the atmospheric concentrations have reached 400 parts per million.
Scientists are using a new tool to measure the impact of climate change on wildlife in Pennsylvania. They found that rare, native Northeastern bulrush is highly vulnerable to climate change. It's also an indicator of how other species will fare as temperatures rise.
