This report projects that climate change will quadruple US outdoor workers’ exposure to hazardous heat conditions by mid-century, jeopardizing their health and placing up to $55.4 billion of their earnings at risk annually without rapid action to reduce global warming emissions.

Flooding during high tides is now common in some places and is projected to grow to the point that sections of coastal cities may flood so often they would become unusable in the near future, according to a report the Union of Concerned Scientists (UCS) released, “Encroaching Tides: How Sea Level Rise and Tidal Flooding Threaten U.S.

This report explains how climate change and development in wildfire-prone areas are driving up the risks and costs of wildfires; points out why current policies and practices may be worsening the situation; highlights the many different impacts and costs of wildfires; and provides recommendations for what we can do to limit these costs.

This report shows how a substantial number of developing countries, home to most of the world’s tropical forests, have reduced deforestation and thus their emissions of the global warming pollution that threatens the world with dangerous climate change.

Deforestation and forest degradation have been occurring for thousands of years. Both deforestation, which completely removes the forest canopy, and degradation, which maintains the canopy but causes losses of carbon, are important sources of global warming pollution, as well as threats to biodiversity and to the livelihoods of forest peoples.

Industrial farming operations apply massive amounts of nitrogen fertilizer to crops

Genetic engineering has been promoted as an important means for dramatically improving the yields of staple food crops, but there is little evidence to support such a claim. In Failure to Yield, the Union of Concerned Scientists provides the most comprehensive evaluation to date of more than two decades of U.S. genetic engineering research and commercialization aimed at increasing crop yield.
