WITH A STATE THAT HAS FAILED TO RECEIVE SIGNIFICANT RAINFALL SINCE 2010, FIRE SEASONS HAVE BEEN GOING FROM BAD TO LOUSY.
Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent.13,14 This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the oceans. 2010; Vostok ice core data/J.R.

A “drought” is an extended period of deficient rainfall relative to the statistical multi-year average for a region. IPCC Fifth Assessment Report, Summary for Policymakers, B.D. GOVERNOR BROWN HAS CALLED ON CALIFORNIANS TO LESSEN WATER USAGE BY 20%. THAT’S WHAT BOB DIEDRICH FARMS HERE IN FRESNO COUNTY. THIS IS THE SAN LUIS RESERVOIR, NEAR FRESNO. NOW, HOW WILL CALIFORNIA ESCAPE ITS CYCLE OF DROUGHT?
“it’s going to make it tough, it’s really hard” Jennifer Morgan on camera The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA.

Travel through Earth's recent climate history and see how increasing carbon dioxide, global temperature and sea ice have changed over time. Arctic sea ice extent both affects and is affected by global climate change. The Drought Center helps people, organizations and institutions build resilience to drought through monitoring and planning, and we are the academic partner and web host of the U.S. Drought Monitor.
Glaciers are retreating almost everywhere around the world — including in the Alps, Himalayas, Andes, Rockies, Alaska and Africa.8. THERE IS ALSO THE NEED TO EXPAND CALIFORNIA’S RESERVOIR SYSTEM - LIKE THE SAN LUIS - FOR MORE BACKUP DURING THE DRY SPELLS.
BECAUSE OF THE DROUGHT, AGRICULTURAL PRODUCTION IN CALIFORNIA IS EXPECTED TO FALL BY 3.5 BILLION DOLLARS, WHICH MEANS 20,0000 FARMERS COULD BE OUT OF THE JOB. BURST OF MUSIC AND CROSS-DISSOLVE TO THE AERIAL DIRT SHOT AND THE TITLE CARD: In five months since the drought emergency was declared, California residents have only cut their water consumption 5 percent compared with recent years

THERE ARE ALSO MUCH-NEEDED INFRASTRUCTURE IMPROVEMENTS. Millions of people, including many children, are going hungry in Africa because of a severe drought there. NCEI ocean heat content, temperature anomalies, salinity anomalies, thermosteric sea level anomalies, halosteric sea level anomalies, and total steric sea level anomalies from 1955 to present calculated from in situ oceanographic subsurface profile data (NCEI Accession 0164586). The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia.1. The U.S. has also witnessed increasing numbers of intense rainfall events.12. VO Dokken, B.C.

Ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent's ice shelf mass loss, a new study by NASA and university researchers has found.
VO Drought is when an area gets less than its normal amount of rain over months or even years.
