We have witnessed a series of utmost weather events together with best temperatures, deadly wildfires, killer floods, and chronic drought within the last summer.

Last Nov a one,600-page quadrennial report Fourth National Climate Assessment discharged by President Trump’s own administration depicted constant gloomy scenario together with wildfires, floods, frequent droughts, and extreme weather inflicting rise in water level, decline in crop yields, increase in disease-carrying insects and reducing U.S. gross domestic product by a tenth by the top of the century.
