Partnerships to Protect Fragile Mountain Ecosystems

Aaron Piña and Jill Baron, , UCS

If you are a cow, Colorado is an ideal place to be. Colorado’s climate is sunny and dry, and these characteristics have helped make the state fourth in the nation for numbers of cattle in feedlots. Weld County, just east of the Colorado Front Range mountains, is the fifth most livestock-rich county in the United States—beef and dairy, swine, sheep, chickens—and produces as much waste as 24.5 million people.

Hurricane Matthew: What’s Next for Recovery and Rebuilding?

, lead economist and climate policy manager

Hurricane Matthew carved a path of devastation through Haiti, the Bahamas, and large swaths of the Southeastern US, including North Carolina, South Carolina, Georgia and Florida. The loss of life and destruction of property is tragic. Slowly, unevenly, places that were hard-hit will be turning to recovery and rebuilding efforts. What can we do to better prepare and protect people and make our rebuilding efforts more resilient going forward?

Washington Moves to Reduce Carbon: A First Step but More Work Remains

, Western states senior climate analyst

Eastern Washington was ablaze with wildfires this August as Governor Inslee declared a state of emergency for twenty counties. And the 2015 fire season was the state’s worst on record. Many factors can increase wildfire risk, and the state of Washington and external experts acknowledge that hotter, drier conditions due to climate change is one of them. It’s against this burnt landscape that the Department of Ecology (or Ecology) released its final Clean Air Rule last month to cap and reduce Washington’s carbon pollution. Read more >

How Should Oil Companies Adapt to a Carbon Constrained World?

, senior scientist, Clean Vehicles

Last week my colleagues released a report on the failure of major fossil fuel companies to make a clean break from disinformation on climate science and policy, or to plan adequately for a world free of carbon pollution as laid out in the international climate agreement reached in Paris in 2015.  Today I want to focus on oil companies, and consider how they should change the way they extract oil and use it to produce gasoline, diesel, and other fuels and products.

Making Agriculture “Climate-Smart” in Latin America and the Caribbean

Sharon Gourdji, , UCS

I recently returned to the United States from Cali, Colombia where I worked for the International Center for Tropical Agriculture (or CIAT, its Spanish-language abbreviation) for a couple years. CIAT is part of a global network of 15 agricultural research centers in the CGIAR (Consultative Group on International Agricultural Research), which have traditionally focused on crop breeding to raise yields of staple crops around the world.  Read more >
