ATMOS Research is a scientific research and consulting firm focused on modeling and assessment of greenhouse gas emissions and controls, climate change, and the impacts of climate change on human and natural systems
at the regional scale.

We specialize in providing detailed reports, maps, and other graphics that vividly illustrate changes that have already been observed, as well as highlighting the possible future impacts of climate change over the coming century.

Slowing Tropical Deforestation Can Contribute to Reducing Gobal Emissions
Deforestation in tropical countries currently accounts for nearly 20% of global carbon emissions. A new study in Science, co-authored by Katharine Hayhoe, shows that cutting deforestation rates in half by mid-century could achieve12% of total emissions reductions needed to stabilize atmospheric CO2 levels at 450 parts per million, emphasizing the essential contribution tropical countries can make to the global effort to avert dangerous climate change.
Climate Impacts on Snowpack and Ski Season Length in the U.S.
In the future, we expect to see less snow and more rain during the winter season as temperatures warm. These changes are likely to affect the ski industry, with less natural snow, fewer days when snowmaking is possible, and shorter ski seasons. By mid-century, the average ski season could be up to 4 weeks shorter for more southern or lower-elevation resorts in the Rocky Mountains and Sierra Nevadas.
Northeast Climate Impacts Assessment
Climate across the Northeast is already changing, with warming temperatures, earlier springs, and more extreme heat. This detailed analysis shows that these changes are likely to continue throughout the coming century, with reduced winter snow, more frequent summer droughts, and major shifts in the timing of the seasons that would dramatically alter the character of the Northeast.

California Climate Action Report
A comprehensive study of climate change impacts on the state of California was commissioned by the governor following the initial study below. The contributions of ATMOS Research show how climate change will affect human health, wildfire risk, coastal infrastructure and many other aspects of life in California.

The State of the Rockies Report
As temperatures warm, snowpack in the Rockies is projected to shrink, reducing the amount of natural snow available to ski resorts. By the end of the century, southern resorts such as Taos or Telluride could lose over 80% of their natural snow if we continue to rely on fossil fuels for energy. In contrast, reducing our emissions could limit snow loss across much of the Rockies to 50% or below, especially for more northern locations and higher elevations.
Drought in West Texas
During the winter of 2005-2006, the High Plains of Texas experienced more than 100 consecutive days without rain. Together with the unusually warm temperatures, soils dried and wildfires blazed across the state. Although climate change is not likely to result in major changes in rainfall across this region, the warmer temperatures it brings will make these conditions more frequent in the future.
Climate Impacts on California
Temperature increases and related impacts on Sierra snowpack, extreme heat events, and other aspects of California climate related to temperature may be twice as high under a higher emissions scenario as compared with a lower one.
Great Lakes – Ecosystems at Risk
Winter is shortening in the Great Lakes region as temperatures warm and ice-free periods become longer. Future changes will magnify the impacts of human disturbances that are already transforming the landscape and disrupting the natural ecosystems of this region.
Regional Climate Change
Producing high-resolution climate projections to assess potential future impacts on ecosystems, agriculture, water resources, snowpack, coastal and marine systems, urban centers, and human welfare.
Climate Policy
Evaluating greenhouse gas emission reduction policies, targets, and the potential for “dangerous human interference with the climate system.”
Energy Use and Emissions
Analyzing emissions of greenhouse gases, aerosols and air pollutants from energy sources and their impact on climate and air quality.
Human-Climate Interactions
Determining the effects of extreme weather events and changing climate on human health, welfare. and energy use.
Earth Science Education & Outreach
Providing presentations, workshops and educational materials addressing important aspects of climate change for high school and undergraduate students, teachers, and the public.
