Donald Trump denies the existence of climate change. But science and data refute him. A new report from the Office of Government Accountability finds that the United States government spent more than $ 350 billion on its responses to extreme changes in temperatures such as floods or fires.
Climate change: human causes
Climate change is called, according to the United Nations Framework Convention on Climate Change (UNFCCC), a climate change applied directly or indirectly to human activity that alters the composition of the world's atmosphere and adds to variability. natural climate observed over comparable periods of time.
Observations of the climate system are based on direct measurements and remote sensing from satellites and other platforms. Observations of temperature and other variables on a world scale began to be made in the instrumental era, in the mid-19th century, and since 1950 there have been more complete and diverse sets of observations.
According to the IPCC's Fifth Report, the warming of the climate system is unequivocal, and since the 1950s, many of the changes have been unprecedented for decades.
Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history. This is evident from increasing concentrations of greenhouse gases in the atmosphere, positive radioactive forcing, observed warming, and climate understanding.
The United States government has spent more than $ 350 billion on disaster assistance programsand in losses due to floods and crop insurance, not counting the ravages of the three major hurricanes and forest fires of the year. Many of these disasters caused by climate change.
The data were provided by areport published this Tuesday by the Government Accountability Office (GAO) This office asks President Trump to use the information provided to develop appropriate federal responses, as well as identify the potential risks that climate change poses to the stability of the country.
The report forecasts that these costs will increase in the future and could reach $ 35 billion a year by 2050 and losses of $ 150 billion by 2099.
The country will be affected to a greater or lesser extent depending on the area. The southeastern region of the country is the one that is in greater danger of disaster due to coastal constructions subject to rising sea levels, flooding due to storm surges, etc.
The north central and Great Plains will be more susceptible to low crop yields.
The west will have greater droughts, fires and deadly heat waves.
By leveraging that information, the federal government could take the initial step of setting general priorities at the government level to address such risks.
The study, completed after two years of interviews with experts and analysis of dozens of documents, is the latest reminder of the serious economic consequences for the United States.
