Federal officials see more smoke and other negative effects on the northwest horizon as a result of climate change. Drought 2015, with high temperatures and water problems, can be a vision for our climate, according to a new report.
The effects of climate change – among them, increased fires, outbreaks of diseases and droughts – take a toll on the northwest, and what will threaten and transform our way of living from salmon streams to ski slopes, according to a new federal climate assessment released Friday.
The 1000 Plus Pages Report, produced by the US Global Change Research Program, is the most comprehensive evaluation so far of the impact of climate change on the nation’s economy, human health, agriculture and the environment. Thirteen federal authorities contributed to the report, which would be published by the Congress.
The federal report’s strong, direct and largely negative forecasts contradict President Donald Trump’s skeptical view of climate science. But federal officials, such as US Oceanic and Atmospheric Management Researcher David Easterling, left some room for ambiguity if climate change was real and who caused it.
Temperature data, said Easterling, gave “clear and convincing evidence that the global average temperature is much higher and growing faster than modern civilization has experienced and that this warming trend can only be explained by human activities …”
Raising of sea level and extreme events as heavy rainfall continues to increase, he said. Soon, if emissions are not significantly reduced, ecosystems will be transformed and the species will be eradicated. By the end of the century, the report says that climate change could reduce the country’s economic output by as much as about 1
The heating temperature is expected to transform the Pacific Northwest as the winter fall increases overall, but with larger variations from year to year, according to a chapter in the federal report as detailed expected effects on the northwest. This means that we can expect more droughts and more extreme rain events.
The northwestern temperatures have risen almost two degrees since 1900, according to the assessment. The idea that climate change effects are in the distant and distant future is wrong, “said Heidi Roop, researcher at the University of Washington’s Climate Impacts Group, which was involved in writing a chapter in the report. “We observe temperature hikes in our region and around the world, now,” she said.
The report predicts that the warming will shake Pacific Northwest’s regional identity into its cultural core.
If the emissions remain uncontrolled, salmon is expected to lose about 22 percent of its habitat since a century because water is watering, reports the report. Revenue from skiing and other snow-based recreation could decrease by more than 70 percent annually.
Northwestern crops already see negative effects, according to the report. Higher weather temperatures cause trees to bloom earlier, creating pollination problems. Summer heat tension can tan apples and berries, causing damage during harvest and transport, according to the report.
More water reservoir storage will be needed to handle changed rainfall patterns (more rain, less snow) and increased irrigation requirements for northwest crops, says the report. Long term temperature changes and heavy heat can force wine production of vine growing. Ocean acidification and harmful algae blooms “can lead to extensive closures of fisheries throughout the region’s coastal fisheries,” the report says.
Nature’s drama will also rise as landslides, fires and floods increase in frequency and intensity. And our infrastructure, designed for the past climate, is not ready, says the report. Saltwater may enter the coastal water supply. More fires can cause more energy, transport and water quality problems.
Pests, firefighting and extreme warmth have now grown, according to the report.
Still Northwest recently saw several cases of Lyme disease, correlating with higher temperatures and change of field habitats, the report says. West Nile falls have risen along with temperatures. In Oregon, E. coli and salmonella infections climbed under high heat. Night heat waves, dangerous here because people are not acclimatized or adapted to hot weather, have increased in the last century.
Earlier this year the firewater Seattle hit an unhealthy dew of liquid particles.
“Not a single person in Washington state did not breathe bad air if you were in August this year,” said Roop. “We breathed firefighting smoke from California, Siberia and British Columbia. This global issue occurs in our farm and touch of life.”
Air quality is likely to worsen, the report says, because the seasons are getting longer due to dry forest conditions.
Also, with greenhouse gas emissions improvements, “Airborne Particle Levels from Fires Spread to Increase 160% in the Mid Century”, according to the report. Respiratory injuries can also follow this development.
Natural disasters and other climate stressors can also increase the risk of mental health problems, according to the report, and notes that Northwest states provide relatively little access to mental health care compared with other states.
We may have already seen a glimpse of our future. In 2015 the temperature was about 3.4 degrees above normal and the winter’s record low snowfall in most places. Agricultural losses exceeded $ 633 million in Washington due to drought, according to the assessment. Some northwestern ski areas never opened. Harmful algae bloomed and high toxins closed salmon, seafood and crab fish along the coast. Wildfires caused Seattle City Light to turn off power transmission lines originating in the northern cascades. Hot water temperatures caused widened salmon depths in several streams.
It was a difficult year, and one that “may be common in the future,” says the report.
