[[Thomas Knutson]] na Robert E. Tuleya wa [[NOAA]] walisema mnamo mwaka wa 2004 kuwa ongezeko la joto uliowezeshwa na [[gesi za nyumba za kijani kibichi]] huenda zikasababisha ongezeko la matukio ya dhoruba za jamii ya 5 ambazo husababisha uharibifu mwingi.<ref>{{cite journal|author = Knutson, Thomas R. and Robert E.

Alipata kuwa idadi ya harikeni za Kiatlantiki na dhoruba za Kitropiki zingepungua kufuatia ongezeko la joto litakalosababishwa na gesi za nyumba za kijani kibichi katika siku za usoni. <ref name="Knutson2008">{{cite journal |last=Knutson |first=Thomas |authorlink= |coauthors=''et al.'' |year=2008 |month= |title=Simulated reduction in Atlantic hurricane frequency under twenty-first-century warming conditions |journal=[[Nature Geoscience]] |volume=1 |issue=6 |pages=359–364 |doi=10.1038/ngeo202 |url= |accessdate= |quote= }}</ref> Vecchi na Soden wanapata kuwa makadirio ya [[upepo wa kukata]], ambayo yanapoongezeka yanapunguza [[saikloni za kitropiki]], pia kunabadilisha mifano iliyotabiriwa ya ongezeko la joto. Kuna makadirio ya ongezeko la idadi ya [[upepo wa kukata]] katika Atlantiki ya Kitropiki na Pasifiki ya Mashariki inayohusishwa na kupungua kwa kipimo cha [[Mzunguko wa Walker]], na pia kupungua kwa kukata kwa upepo katika eneo la magharibi na kati la Pasifiki.<ref>{{cite web |url=http://www.gfdl.noaa.gov/~gav/ipcc_shears.html |title=IPCC Projections and Hurricanes |publisher=Geophysical Fluids Dynamic Laboratory|accessdate=2007-12-06|author=Brian Soden and Gabriel Vecchi}}</ref>
Hatari kubwa zaidi ya hali kali ya hewa haimaanishi hatari kubwa iliyo wazi ya hali ya hewa ambayo haifanani na ile ya wastani.<ref>{{cite web |url=http://www.climateprediction.net/science/pubs/ccs_allen.pdf |author=Myles Allen | authorlink=Myles Allen |publisher=climateprediction.net |accessdate=2007-11-30 |title=The Spectre of Liability|format=PDF}}</ref> Hata hivyo, ushahidi ni wazi kuwa hali kali ya hewa na mvua ya wastani pia vinaongezeka. Kuongezeka kwa idadi ya joto kunatarajiwa kuzalisha mawimbi makali zaidi juu ya ardhi na idadi kubwa zaidi ya dhoruba kali sana.<ref>{{cite journal|last = Del Genio | first = Tony | coauthors = ''et al.''|title=Will moist convection be stronger in a warmer climate?|journal = Geophysical Research Letters | volume = 34 | doi = 10.1029/2007GL030525|year=2007|pages=L16703}}</ref>
