Exacerbation of drought in the west arouses fears of the upcoming wildfire season
Duplicate from a drought monitor in the United States. Chart: Sarawise It’s only in early April, but parts of the west are already at dry levels in mid-July — and scientists warn that the upcoming fire season may be devastating. Importance: This summer has been a year since the historic wildfire broke out on the west coast. Another tough fire season outlook raises concerns about water supply and questions about how to prepare the region for climate change devastation.

Free subscription details: Against the backdrop of a long-term artificial drought, the current drought is projected to spread and become even more severe in many parts of the west, from Colorado to Montana and from the southwest to California and Arizona. Forty percent of the west falls from “extreme” droughts to “exceptional” droughts. This is the two most serious categories. With the arrival of the warmer season, widespread precipitation prospects are declining rapidly, and scientists are warning about the recurring deadly wildfire season of 2020. In an email, Columbia University’s climate researcher Ben Cooke said, “The situation could improve significantly as we move into warmer months when water demand from ecosystems and people is likely to actually increase. Is almost nonexistent. ” For example, California has two consecutive winters, drier than average, and temperatures consistently above average. In the Colorado River basin, the fire season can be even more severe as the snowfall has already melted rapidly earlier than the start of the normal melting season. Context: “Forefront of wildfires: I’m very worried about what will happen this year, especially from midsummer to autumn,” UCLA climate scientist Daniel Swain said in an email. “I fully anticipate another very severe fire season across the west in 2021.” Of further concern is the west, mainly due to the effects of anthropogenic climate change. The autumn rainy season arrives later in the year, which increases the number of days with extreme fire hazards, Swain said. More than 4.2 million acres burned in California in 2020, but there are still many forests that did not burn recently or burned a few years ago and regrown. Park Williams, a geographer at the University of California, Los Angeles, loads dice for a large wildfire. ” Threats in so-called “fuel limit” locations where flammables tend to be low Note: California has repeatedly ignited wildfires from electrical equipment by initiating rolling blackouts during high periods. Adapted to the case Bloomberg reports that the state is adding large numbers of batteries for energy storage as part of its extensive climate planning. These may mitigate some of the effects of planned power outages. Droughts in California can affect agricultural producers, who are the largest users of water resources in the state. They were able to see reduced water allocations to save more water for species protection in rivers and drinking water supplies. How it works: Climate change is intensifying droughts, heat waves, and wildfires as soil dries faster and weather patterns change as temperatures rise. According to a survey by Cook and several colleagues, the period since 2000 is the second driest in 22 years. For the past 1200 years, across the western multi-state region. According to Williams, soil moisture in March was at its lowest level throughout the west for at least 120 years. The study found that the ongoing drought was the first human-led “mega-drought” on record, not the last. Dig deeper: A very, very, very dry future in the western United States Like this article?
