Colorado Could Face Droughts Every Six Years Due to Climate Change
A study warns that Colorado could face extreme droughts every six years by 2100 due to climate change. Researchers highlight the urgency of reducing greenhouse gas emissions to combat worsening drought conditions, as seen in the recent drought from 2020 to 2022, which fueled record wildfires and posed significant threats to air quality and water resources.
A recent study indicates that Colorado and the broader western United States may face extreme droughts every six years by the century’s end if global temperatures continue to escalate. Researchers attribute the worsening drought conditions to climate change and stress the urgency for proactive measures to mitigate greenhouse gas emissions. Previously rare severe droughts, like the one from 2020 to 2022, have become significantly more frequent due to rising temperatures, which enhance drought severity and occurrence.
Joel Lisonbee, a scientist with the University of Colorado Boulder, remarked that future droughts in the region are predicted to be longer, more expansive, and increasingly harsh, as highlighted in a report from The Denver Post. The drought from 2020 to 2022 exemplified the dire consequences of climate change in the West, with research indicating that elevated temperatures contributed 61% to the drought’s severity, complemented by a 39% impact from reduced precipitation. These conditions were instrumental in triggering Colorado’s three largest wildfires on record, engulfing over 541,000 acres and leaving lasting environmental destruction, including mudslides that obstructed Interstate 70 and resulted in deadly flash floods.
The severity of wildfires can exacerbate air quality, with the Boulder County Marshall Fire in December 2021 underscoring the year-round threats posed by these fires. The smoke from these incidents contributed to some of the poorest air quality rankings globally observed in the Front Range area. As per a study published in Science Advances, increased atmospheric temperatures yield higher water vapor content, leading to enhanced evaporation and diminished precipitation, creating a feedback loop that worsens drought conditions. Traditional measures like constructing reservoirs are now deemed inadequate.
Rong Fu, a prominent atmospheric sciences professor at UCLA and the lead author of the study, stated, “The only way to prevent this is to stop temperature increases, which means reducing greenhouse gas emissions.” In light of the 2020 drought, severe conditions were noted in every county in Colorado, prompting Governor Jared Polis to declare an emergency in 21 counties on the Western Slope. Experts assert that without decisive intervention, Colorado’s water resources, agricultural sector, and communities will continue to grapple with the challenges posed by these escalating drought scenarios.
The growing concern regarding extreme droughts in Colorado and the western United States is rooted in the broader implications of climate change. Historical records show that severe droughts were once rare, occurring approximately once every 1,000 years. However, the alarming increase in global temperatures attributed to human activity is altering this pattern, leading to more frequent and extreme drought-like conditions that threaten agriculture, water resources, and overall community resilience. Recent drought events, particularly from 2020 to 2022, have demonstrated not only the immediate impacts of climate change but also the long-term consequences if current trends continue.
The study underscores the urgent need for concerted climate action in Colorado and surrounding regions to mitigate the severe impacts of recurring droughts. With predictions suggesting extreme droughts every six years by century’s end, it is imperative that policymakers prioritize greenhouse gas reduction strategies to protect the state’s water supply, agricultural output, and community health. Without swift and sustained actions, the repercussions of climate change will continue to intensify, exacerbating the hardships faced by thousands.
