This will bring more spring floods and intense erosion, followed by extended periods of summer drought. Colorado has warmed: Statewide average annual temperatures are 2 degrees Fahrenheit higher than they were three decades ago. The full brunt of climate change is bearing down on Colorado. Climate models tend to show a shift toward higher mid-winter precipitation across the state. Program, synthesis and assessment products by the U.S. Global Change Research . Colorado Climate Preparedness Project - Final Report. A Report for the Colorado Water Conservation Board. “This report will add value, just as the 2008 report was widely used by the state and other entities to inform their long-term planning processes such as the Colorado Drought Mitigation and Response Plan and the city of Denver’s Climate Adaptation Plan.”. Katherine Delanoy has been waiting for the public to catch up with her on climate change. 2014) is a synthesis of climate science relevant for management and planning for Colorado’s water resources. The sources of information about climate and the impacts of climate change in this publication are: the national climate assessments by the U.S. For first time in 8 years, 100% of Colorado is under drought or abnormally dry conditions Federal designation is consistent with wider transformation of Southwest amid climate change Colorado has warmed substantially in the last 30 years and even more over the last 50 years. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Colorado Climate Preparedness Project Database described in the report : Ray, A., J. Barsugli, and K. Averyt (2008). DENVER (KDVR) -- On Oct. 24 and 25, 1997, a blizzard hit Colorado, dumping snow on the Front Range and Plains. A 2-degree increase would make Denver’s temperatures in 2050 more like Pueblo’s today. Read the full report at http://wwa.colorado.edu/climate/co2014report. “Wildfires and heat waves have become more common, too. The 2014 report is a thorough revision and expansion of the 2008 report of the same name, also produced … Even if the future brings more precipitation, the report notes, skiers, farmers and cities may not benefit because a warmer atmosphere will pull more moisture out of the state’s snowpacks, soils, crops and other plants. The 88-year-old of Eagle, Colorado, said she first started … Climate models indicate that the state’s average annual temperature will continue to increase, by 2.5 to 6.5 degrees F by 2050. NOAA-led study shows Alaska fisheries and communities at risk from ocean acidification, Summer of research to improve hurricane forecasting, High-resolution snow projections developed to inform wolverine conservation, Lawns provide surprising contribution to L.A. Basin’s carbon emissions, The warmest summer on record for the Northern Hemisphere comes to an end, New research finds the Western U.S. is a hot spot for "snow droughts", NOAA names University of Miami to host cooperative institute, http://wwa.colorado.edu/climate/co2014report. In producing “Climate Change in Colorado,” the authors sought to provide information that would be useful to people involved in making long-term decisions about Colorado’s water in the face of climate change. Climate projections suggest those trends—all of which can affect water supply and demand—will continue.”. A 2015 studyon wildfires in the Colorado Front Range Corridor found that the expansion of the wildland-urban Interface — more people living on the edge of forests — and climate change … The newest climate models are split on whether the future will see increasing, decreasing or similar amounts of annual precipitation in Colorado. Climate models are split about Colorado’s future precipitation, showing a range of possible outcomes from a 5 percent decrease in precipitation to an 8 percent increase by mid-century. Climate Change Science Program, assessment reports by the Intergovernmental Panel on Climate Change, and EPA’s Jared Polis released a draft of his plan to stem the tide Wednesday. For more information, please contact: Katy Human,kathleen.human@colorado.edu, 303-735-0196. This news release was provided by the NOAA Cooperative Institute for Research and Environmental, Sciences at the University of Colorado in Boulder. It focuses on observed climate trends, climate modeling, and projections of temperature, precipitation, snowpack, and streamflow. In Colorado, climate change presents a broad range of challenges. The Colorado Water Conservation Board (CWCB) is a division of the Colorado Department of Natural Resources and spearheads the state’s climate change adaptation efforts. Colorado has seen no long-term increase or decrease in total precipitation or heavy rainfall events. Observations show there have already been increasing trends in these three extremes over the past 30 years. Climate change hits home in Colorado with raging wildfires, shrinking water flows and record heat For first time in 8 years, 100% of Colorado is under drought or abnormally dry conditions Warmer temperatures and other changes (dust on snow) mean that snowpack is melting earlier, on average, by one to four weeks compared with 30 years ago. The Climate Change in Colorado report (Lukas et al. A 4-degree increase would make Denver more like Lamar in southeastern Colorado, and a 6-degree shift would push Denver’s temperatures beyond any found in Colorado today, to more like those in Albuquerque, New Mexico, today. Climate change has dramatically decreased natural flow in the Colorado River, jeopardizing the water supply for some 40 million people and millions of … Future warming in the state is likely to lead to more heat waves, wildfires and droughts. “Despite some uncertainties around precipitation, it’s clear that as temperatures rise in Colorado, there will be impacts on our water resources,” said Jeff Lukas, lead author of the new report and a researcher at the Western Water Assessment, a program of the University of Colorado Boulder funded by the National Oceanic and Atmospheric Administration. Climate change The Colorado Department of Public Health and Environment created the Climate Change Unit in December 2019 to lead an ambitious effort to reduce greenhouse gas emissions to protect a livable climate. Climate change has dramatically decreased natural flow in the Colorado River, jeopardizing the water supply for some 40 million people and millions of … Prepared by the Western Water Assessment for the State of Colorado. “This report will help to inform critical products like the Statewide Water Supply Initiative (SWSI) and Colorado’s Water Plan,” said James Eklund, Colorado Water Conservation Board director. In metro Denver, snow totals ranged from 14 to 31 inches. You can read the CIRES release online. This means the warmest summers from our past may become the average summers in our future. Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. This creates a strain for farmers and other users who draw water directly from rivers. In that context, Gov. “Already, snowmelt and runoff are shifting earlier, our soils are becoming drier, and the growing season has lengthened,” Lukas said. Future estimates project temperatures rising an additional 2.5 °F to 5 °F by 2050. Among the findings presented in the new report: The Western Water Assessment (WWA) is part of the Cooperative Institute for Research in Environmental Sciences (CIRES), a joint institute of CU-Boulder and the National Oceanic and Atmospheric Administration (NOAA). Co-authors of the report are: Joseph Barsugli, of CIRES and NOAA’s Earth System Research Laboratory (ESRL); Nolan Doesken, of Colorado State University and Colorado Climate Center; Imtiaz Rangwala, of WWA; and Klaus Wolter, of CIRES and ESRL. Colorado report: climate change projected to reduce water in streams, increase water needs for crops, cities This news release was provided by the NOAA Cooperative Institute for Research and Environmental Sciences at the University of Colorado in Boulder. (American Meteorological Society, 2005) Snow is melting 15-30 days earlier than it was 25 years ago. Rising temperatures will tend to reduce the amount of water in many of Colorado’s streams and rivers, melt mountain snowpack earlier in the spring, and increase the water needed by thirsty crops and cities, according to the new report, “Climate Change in Colorado: A Synthesis to Support Water Resources Management and Adaptation,” which updates and expands upon an initial report released in 2008. You can read the. Hydrology models show a wide range of outcomes for annual streamflow in Colorado’s river basins, but an overall tendency towards lower streamflow by 2050, especially in the southwestern part of the state. Warmer spring temperatures are increasing the speed of early snowmelt in the Rocky Mountains. For more information, please contact: Katy Human. The Colorado report comes on the heels of international and national assessments that discuss likely impacts of climate change in broad regions, and it leverages those assessments to provide state-specific information. The … Because Colorado is located between an area likely to dry further (the U.S. Southwest) and one likely to get wetter (Northern Great Plains), our precipitation future is less certain. The Report. As Colorado’s climate continues to warm, those who manage or use water in the state will likely face significant changes in water supply and demand, according to a new report on state climate change released today by the Western Water Assessment and the Colorado Water Conservation Board.
