The climate debate in Washington is stuck in a rut. Last week, we saw politicians playing another round of the climate change blame game. This time the topic was tornadoes. But connections between extreme weather and climate change are a scientific question, not a political one. Read More

Tomorrow the Environmental Protection Agency (EPA) will likely miss a legal deadline for finalizing its draft carbon standard for curtailing carbon emissions from new power plants. Power plants are the single largest stationary source of U.S. global warming emissions. Cutting those emissions is critical to slowing the magnitude and pace of climate change. Furthermore, an ambitious standard is achievable because we have abundant cleaner forms of energy. So why the delay? Read More

The Environmental Protection Agency (EPA) is expected to soon finalize carbon standards for new power plants, bolstering the existing market trend away from building new coal-fired power plants. Next up is the carbon standard for existing power plants – a major source of U.S. global warming emissions. Designing this standard with the flexibility to include renewable energy and efficiency as compliance options can help achieve deep emissions reductions at an affordable cost. Read More

As Hurricane Sandy approached Virginia Beach, I watched churning surf form a troublesome backdrop to two skateboarders harnessing the wind to propel themselves rapidly along the boardwalk. Those same winds were piling up water to form a dangerous storm surge and portended a powerful blow that would ultimately cause widespread devastation throughout the region. Since that moment, I have been asked many questions about Hurricane Sandy. Here are answers to the most common ones. Read More
Evidence Check: Which Extreme Weather Events Are More Linked with Climate Change – Heat Waves or Hurricanes?
July 16th, 2012
The heat gripping the United States this month has been relentless. And if that weren’t enough, hurricane season is upon us. How does the scientific evidence stack up over the past decades regarding how these extreme events are changing? And how much influence does human-caused climate change have on these events? We created an infographic to serve as a quick reference of the current state of scientific understanding.
