Fishermen discuss warming waters in this lovely short film

When you are tired of talking to climate deniers, it can be a relief to hear from a fisherman instead.

“The waters are changing,” says Michigan fisherman Ed John in this short, moody video that follows a Native couple fishing the Great Lakes. “We’ve got algae, we’ve got invasive species, we got all of these pollutants we don’t know about going into the water.”

New Release: Second Nature Sustainability Sit-Downs Video #8

Sustainability Sit-Downs #8 is out. This week’s video features Richard Cook, President Emeritus of Allegheny College and Second Nature Board Chair, discussing trans-disciplinary sustainability education and our effects as humans on the environment. Sustainability Sit-Downs is a new Second Nature video series consisting of 12 short interviews with sustainability leaders in higher education and partner organizations. A new video will be released every Wednesday.

8 Big Ideas: Cool Roofs Through Time and Space

The Global Cool Cities Alliance posted a video of Dr. Ronnen Levinson of Lawrence Berkeley National Lab explaining how the reflectivity of cool roofing materials changes over time, with the accumulation of dust, soot, and other contaminants.

Institute for Tribal Environmental Professionals releases video highlighting climate change impacts on tribes in the Pacific Northwest and Alaska

The Institute for Tribal Environmental Professionals (ITEP) recently produced a video, “Adapting to Change,” that highlights climate change impacts on tribes and their resources in the Pacific Northwest and Alaska, as well as their adaptation efforts. The video also includes information from ITEP’s Climate Change Adaptation training.

This Spring, Look for the Safer Choice Label

Read the full post at EPA Connect.

Today, we’re unveiling a new Safer Choice label, which will make it easier to find household cleaners and other home products that are safer, more environmentally friendly—and still get the job done. If you missed the video where I shared the new label, check it out here:

The name says it all: Safer Choice products are safer for you, your kids, your pets and the environment. Our scientists employ a stringent set of human health and environmental safety standards when reviewing products for the Safer Choice program, so a product with the label is backed by EPA science. Consumers know it’s a credible stamp they can trust.

New Tool Maps Buildings’ Energy Efficiency

Read the full story from Voice of America.

Architects, engineers and building managers will soon be able to quickly collect data about building interiors that once took weeks to measure and process. A backpack-mounted device, developed by a group of scientists at the University of California, Berkeley, will require just one pass through the building to create not only a 3D model but gather other valuable information related to the building’s energy efficiency.

Study unearths impacts of our growing carbon emissions — and it’s not pretty

Scientists have directly confirmed what they have long assumed to be true: Increasing amounts of greenhouse gases in the atmosphere, such as carbon dioxide, are trapping heat from escaping back into space and are thereby causing global warming.

The observations of what is known as radiative forcing were made over the course of 11 years between 2000 and 2010 from two locations in North America, in Oklahoma and the North Slope of Alaska. Highly specialized instruments in both locations were used to measure thermal infrared energy fluctuations and analyze the source of such changes.

The study, published Wednesday in the advance online edition of the journal Nature, explores the Earth’s energy account balance. It found that over time, the planet is running a surplus of energy at the surface, causing global air and ocean temperatures to increase with a wide variety of mostly negative impacts.

These graphs show carbon dioxide’s increasing greenhouse effect at two locations on the Earth’s surface. The first graph shows C02 radiative forcing measurements obtained at a research facility in Oklahoma. As the atmospheric concentration of C02 (blue) increased from 2000 to the end of 2010, so did surface radiative forcing due to C02 (orange), and both quantities have upward trends. This means the Earth absorbed more energy from solar radiation than it emitted as heat back to space. The seasonal fluctuations are caused by plant-based photosynthetic activity. The second graph shows similar upward trends at a research facility on the North Slope of Alaska. (Credit: Berkeley Lab)
