NOAA Report Destroys Global Warming Link To Extreme Weather

Sci­en­tists at the Nation­al Ocean­ic and Atmos­pher­ic Admin­is­tra­tion have demol­ished claims by glob­al warm­ing activists that glob­al warm­ing caused or wors­ened many extreme weath­er events last year.

Accord­ing to NOAA’s new pub­li­ca­tion, Explain­ing Extremes of 2013 from a Cli­mate Per­spec­tive, there is no dis­cernible con­nec­tion between glob­al warm­ing and 2013 extreme weath­er events such as the Cal­i­for­nia drought, Col­orado floods, the UK’s excep­tion­al­ly cold spring, a South Dako­ta bliz­zard, Cen­tral Europe floods, a north­west­ern Europe cyclone, and excep­tion­al snow­fall in Europe’s Pyre­nees Mountains.

The Cal­i­for­nia drought pro­vides a good exam­ple of glob­al warm­ing activists mak­ing false and irre­spon­si­ble claims regard­ing glob­al warm­ing to delib­er­ate­ly mis­lead peo­ple who aren’t famil­iar with sci­en­tif­ic stud­ies and evi­dence. The lib­er­al Cen­ter for Amer­i­can Progress and its media allies such as the Wash­ing­ton Post, San Jose Mer­cury News, Asso­ci­at­ed Press, and oth­ers have all pub­lished sto­ries claim­ing glob­al warm­ing caused or wors­ened the ongo­ing Cal­i­for­nia drought. Sci­en­tists, how­ev­er, say just the oppo­site. “[F]or the Cal­i­for­nia drought, which was inves­ti­gat­ed by three teams from the Unit­ed States, human fac­tors were found not to have influ­enced the lack of rain­fall,” NOAA report­ed in an accom­pa­ny­ing press release.

Adding addi­tion­al empha­sis to the NOAA publication’s find­ings, sci­en­tists report­ed in the peer-reviewed Pro­ceed­ings of the Nation­al Acad­e­my of Sci­ences that nat­ur­al fac­tors such as ocean cur­rent cycles and vary­ing wind pat­terns caused most of the warm­ing along the U.S. West Coast since 1900.

So, sci­en­tists report that most of the warm­ing in Cal­i­for­nia is nat­ur­al, and the evi­dence shows no link between glob­al warm­ing and the Cal­i­for­nia drought. Nev­er­the­less, agen­da-dri­ven activist groups and their media lap­dogs repeat­ed­ly tell the lie that glob­al warm­ing is caus­ing California’s drought. Iron­i­cal­ly – or not – Pres­i­dent Barack Oba­ma and Sec­re­tary of State John Ker­ry fre­quent­ly claim glob­al warm­ing is respon­si­ble for the Cal­i­for­nia drought, all the while claim­ing peo­ple who dis­agree with them are mem­bers of the Flat Earth Soci­ety. Some­body tell that to the fed­er­al government’s own sci­en­tists at NOAA.

Sim­i­lar­ly, glob­al warm­ing alarmists fre­quent­ly claim glob­al warm­ing caus­es extreme cold tem­per­a­tures and extreme snow­storms. Ana­lyz­ing two of these claims, NOAA found no evi­dence link­ing the events to glob­al warm­ing. To the con­trary, NOAA report­ed “Analy­sis of UK cold spring showed the prob­a­bil­i­ty of occur­rence may have fall­en 30-fold due to glob­al warm­ing.” So, glob­al warm­ing not only played no role in the UK’s cold 2013 spring, but glob­al warm­ing made the dis­rup­tive event 30 times less like­ly than would oth­er­wise be the case. Nev­er­the­less, shame­less alarmists such as Nation­al Geo­graph­ic News claimed glob­al warm­ing was respon­si­ble for the extreme­ly cold spring. Despite the NOAA find­ings, Nation­al Geo­graph­ic News has yet to issue a retraction.

The dis­par­i­ty between sci­ence on the one hand and glob­al warm­ing activists and alarmist media cov­er­age on the oth­er hand is par­tic­u­lar­ly strik­ing regard­ing the Col­orado floods of Sep­tem­ber 2013. Glob­al warm­ing activists and their media allies wast­ed absolute­ly no time exploit­ing the vic­tims of the dead­ly floods to make irre­spon­si­ble claims that glob­al warm­ing was to blame. NOAA sci­en­tists, how­ev­er, report glob­al warm­ing played no role and may be mak­ing such trag­ic events less like­ly. Mod­el­ing of past and present Col­orado rain­fall events “found that the prob­a­bil­i­ty of anoth­er extreme 5‑day rain­fall, like the one that caused wide­spread flood­ing in Boul­der, is esti­mat­ed to have decreased because of human-caused cli­mate change,” NOAA reported.

Accord­ing to NOAA, heat waves were nev­er­the­less exac­er­bat­ed by glob­al warm­ing. Of course, any ampli­fi­ca­tion in heat waves is coun­ter­bal­anced by extreme cold events becom­ing 30 times less like­ly. Impor­tant­ly, glob­al warming’s reduc­tion of extreme cold events pro­vides more human health and wel­fare ben­e­fits than any harm caused by an increase in heat waves. Offi­cial gov­ern­ment mor­tal­i­ty sta­tis­tics show peo­ple are much more like­ly to die dur­ing win­ter months and extreme cold events than dur­ing sum­mer months and heat waves.

The next time you hear politi­cians and glob­al warm­ing activists claim glob­al warm­ing is caus­ing or wors­en­ing extreme weath­er events, know that the objec­tive sci­ence shows they are telling self-serv­ing lies.
