A 2011 study projected that the frequency and magnitude of both maximum and minimum temperatures would increase significantly as a result of global warming. [13] According to the Fifth National Climate Assessment published in 2023, coastal states including California, Florida, Louisiana, and Texas are experiencing "more significant storms and extreme swings in precipitation".
The National Weather Service office of the NOAA defines drought as "a deficiency of moisture that results in adverse impacts on people, animals, or vegetation over a sizeable area". [17] Drought is a complex phenomenon − relating to the absence of water − which is difficult to monitor and define. [18]
California is the most populous state and largest agricultural producer in the United States, and as such, drought in California can have a severe economic as well as environmental impact. The historical and ongoing droughts in California are caused by lack of rainfall (or snowfall), higher average temperatures , and drier air masses in the ...
As nearly 40% of the country is currently in drought, scientists are looking to the largest rodent in North America for help: the beaver.Researchers in California and Utah found that dams made by ...
Progression of the drought from December 2013 to July 2014. The 2011–2017 California drought persisted from December 2011 to March 2017 [1] and consisted of the driest period in California's recorded history, late 2011 through 2014. [2] The drought wiped out 102 million trees from 2011 to 2016, 62 million of those during 2016 alone. [3]
According to the NOAA Drought Task Force report of 2014, the drought is not part of a long-term change in precipitation and was a symptom of the natural variability, although the record-high temperature that accompanied the recent drought may have been amplified due to human-induced global warming.

The 2012–2013 North American drought, an expansion of the 2010–2013 Southern United States drought, originated in the midst of a record-breaking heat wave.Low snowfall amounts in winter, coupled with the intense summer heat from La Niña, caused drought-like conditions to migrate northward from the southern United States, wreaking havoc on crops and water supply.

A drought refuge is a site that provides permanent fresh water or moist conditions for plants and animals, acting as a refuge habitat when surrounding areas are affected by drought and allowing ecosystems and core species populations to survive until the drought breaks.
