Without climate change, the drought was probably finished already in 2005. [29] 42% of its severity is due to temperature rise as a result of climate change. 88% of the area was drought-stricken. The flow of the Colorado river supplying water to 7 states had "shrank to the lowest two-year average in more than a century of record keeping."
Source states: "This graph shows cumulative changes in sea level for the world’s oceans since 1880, based on a combination of long-term tide gauge measurements and recent satellite measurements. This figure shows average absolute sea level change, which refers to the height of the ocean surface, regardless of whether nearby land is rising or ...
On average, San Diego sees 21 days with some precipitation while the rest of the country sees about 110. The national average for mostly sunny days is 213 while San Diego's is 267. San Diego's annual snowfall is 0 inches per year while the nation usually sees an average of 24.2 inches (610 mm) per year.
According to 2007 estimates by the Intergovernmental Panel on Climate Change (IPCC), "global average sea level will rise between 0.6 and 2 feet (0.18 to 0.59 meters) in the next century. [88] Along the U.S. Mid-Atlantic and Gulf Coasts, however, the sea level rose 5 to 6 in (130 to 150 mm) in the last century, which is more than the global average.
Historical sea level reconstruction and projections up to 2100 published in 2017 by the U.S. Global Change Research Program [193] Global sea level is rising as a consequence of thermal expansion and the melting of glaciers and ice sheets. Sea level rise has increased over time, reaching 4.8 cm per decade between 2014 and 2023. [194]
Tucson has a hot desert climate (Köppen BWh), with two major seasons, a hot summer and mild winter. Tucson averages 10.61 inches (269.5 mm) of precipitation per year, concentrated during the Pacific storms of winter and the North American Monsoon of summer. Fall and spring tend to be sunny and dry.

The change in the total mass of ice on land, called the mass balance, is important because it causes changes in global sea level. High-precision gravimetry from satellites in low-noise flight has determined that in 2006, the Greenland and Antarctic ice sheets experienced a combined mass loss of 475 ± 158 Gt/yr, equivalent to 1.3 ± 0.4 mm/yr ...
The Climate Clock was launched in 2015 to provide a measuring stick against which viewers can track climate change mitigation progress. The date shown when humanity reaches 1.5°C will move closer as emissions rise, and further away as emissions decrease. An alternative view projects the time remaining to 2.0°C of warming. [1] [2] The clock is ...
