Climate crisis.  There will be water shortages in the western United States

Climate crisis. There will be water shortages in the western United States

  • The water access crisis is increasing, especially affecting one of the fastest growing cities in the United States – Kinder explained
  • Everything west of Mississippi has been bad on the water for centuries. But climate change means the current working model is no longer possible, the scientist said
  • According to Kinder, drought and water problems are one of the problems that can worsen over time, such as wildfires or unusually strong heat waves.
  • Both nature and we are able to adapt to higher temperatures. But not when the pace of change is too fast, he warns, Kinder added
  • Many such texts can be found on the main page of Onet.pl.

– Many cities in the west, such as Denver, Phoenix and Los Angeles, were built knowing that there was limited water and that these places were never intended for large numbers of people to live. So this water crisis is going to get worse, especially since these are the fastest growing cities in the United States, Kinder explained.

According to an expert from the University of Fairfax in Virginia, near Washington, on Monday. New International Commission of Experts Report on Climate Change (IPCC) With the exception of Alaska – the U.S. West is pointing out that the effects of climate change will be felt very hard.

“Everything west of Mississippi has been bad on the water for centuries, but climate change means that the current operational model is no longer possible. It applies to everyday life, the environment and agriculture,” Kinder says.

During the heat wave in June, water levels in major reservoirs such as Mead Lake in Arizona dropped to an all-time low of 95%. Territory of the Western States.

According to Kinder, drought and water problems are just one of the many problems that can worsen over time, such as wildfires and unusually strong heat waves.

“This year we’ve seen in the northwest where temperature records have been broken by a few degrees – unheard of – this is just the beginning.” Kinder says we are currently at 1.1 degrees Celsius warmer than in the pre-industrial period and, according to the current path, will reach 1.5 degrees in twenty years.

– Nature and we are both able to adapt to higher temperatures. But not when the pace of change is too fast, he warns.

The east of the country, especially the coast, will experience changes due to rising sea levels. Although the report predicts that its level will rise to about 60-80 cm by the end of the century, it is theoretically sufficient to cause major flooding on the east coast, especially in Florida.

“Here in Virginia, Norfolk, we have the largest ports and the most important naval base. All of this infrastructure was built under conditions that existed decades ago and is not adapting to these changes,” Kinder says.

According to the expert, there are two main conclusions from the IPCC report: it is almost certain that the level of warming will exceed 1.5 degrees by 2050 – which is the limit set by the Paris Agreements and it will be too late to stop the changes in the next 2-3 decades. The world can further reduce the magnitude of the problems associated with long-term change. However, first and foremost action is needed to stop the increase in CO2 levels in the atmosphere and then begin to reduce it.

– We have a large amount of technology for this. The issue is mainly political will and economics, the scientist believes.

He added that Europe and Poland were slightly less prone to climate change and sea level rise than the United States. However, the so-called changes in the Atlantic meridian thermohaline cycle (AMOC), which includes the Gulf Stream, are responsible for Europe’s temperate climate. Recent research by Niklas Boers of the Batstom Institute for Climate Impact Research shows this.

– Boers’ work is certainly confusing and suggests that the collapse of this system could indeed occur and be the result of major changes, including the cooling of Europe. However, there are many more unknowns about this. If this really happens, it will be in the lives of our children or grandchildren – the climate expert estimates.
