New research focuses on biophysical impacts of climate change
Vegetation plays a key role in the climate change equation, with a recent study showing that vegetation density has substantial climate impacts. According to the research by the European Union’s Joint Research Center, the findings show that vegetation has a warming effect in cold areas and cooling effect in warm areas.
Figuring out the net effect would help develop more integrated and effective climate mitigation and adaptation strategies. The puzzle is complex. Increasing greenhouse gases spur vegetation growth, but the overall effects at the global level are not clear. The new study explores how changes in leaf area (a measure of vegetation density) affect local climate. Continue reading “Increased greening amplifies global warming in boreal zones”→
Ice age ocean current disruptions linked with greenhouse gas changes
Scientists say they’ve discovered another huge climate warning sign in the Arctic. Past increases in CO2 levels in the air drove ocean currents to a tipping point had a big impact on hemispheric weather patterns.
Many of the previously existing pages on climate science, greenhouse gases and global warming impacts are no longer available at the current EPA website.

Continuing its Orwellian policies of trying to create an alternative, fact-free reality, the Trump administration has started to remove climate-related information from the EPA website. As of Friday, April 28, a Google search for EPA climate information leads to a page-update notice, including a statement from a politically appointed spokesperson saying,” “We want to eliminate confusion by removing outdated language first and making room to discuss how we’re protecting the environment and human health by partnering with states and working within the law.” Continue reading “EPA removes web pages with climate change information”→
EPA administrator Scott Pruitt may have to back up his false claims on greenhouse gases and climate change in court. A lawsuit filed April 13 by the watchdog group Public Employees for Environmental Responsibility wants the agency head to show studies backing up his statements that call into question the role of CO2 emissions in global warming. The lawsuit also seeks to determine whether EPA possesses a single study that supports Mr. Pruitt’s stance. Continue reading “EPA chief sued for ‘spouting deceptive climate pseudo-science’”→
Anti-environmental agency head may have violated EPA policies and lied to Congress under oath
By Bob Berwyn
There’s little question that Scott Pruitt is the worst possible person to lead the EPA. He’s been involved in more than a dozen lawsuits against the agency and he’s called for it to be abolished completely, so it’s no surprise that he’s a target for bitter criticism from conservation groups. But his troubles are about to get much bigger than indignant tweets.
The Sierra Club has filed a formal complaint with the Inspector General of the Environmental Protection Agency demonstrating that EPA Administrator Scott Pruitt has violated the Agency’s Scientific Integrity Policy in multiple ways. The filing calls for an investigation into and resolution of Pruitt’s comments on carbon dioxide’s role in fueling the climate crisis.

Last week the UN celebrated the International Day of Forests as a way to acknowledge how important forests are to the world. To cynics, it may seem trite lip service by faceless bureaucrats. But in reality, it’s critical that everyone understands how important forests are for the planet. They cover about a third of the Earth’s land mass and provide livelihoods, medicines, fuel, food and shelter for about 1.6 billion people – including more than 2,000 indigenous cultures. Forests are the most biologically-diverse ecosystems on land, home to more than 80 percent of the terrestrial species of animals, plants and insects. They may also be one of our last, best hopes for slowing climate change. Yet despite all of these priceless ecological, economic, social and health benefits, global deforestation continues at the rate of about 32 million acres per year, equivalent to 10-20 percent of global greenhouse gas emissions contributing to climate change. Check out my article and photo essay for Pacific Standard to learn more about forests, especially for ways you can get involved in helping to protect and restore them.
