(decreased albedo,
increased water vapour etc).
Not exact matches
Recent studies have shown a doubling of stratospheric
water vapour, likely from
increasing atmospheric heights due to global warming, overshooting thunderstorm tops from stronger tropical cyclones and mesoscale convective systems
etc...
The rise of CO2 from 270ppm to now over 400ppm, the extent of equatorial and sub tropical deforestation, the soot deposits on the polar ice caps, the
increase in atmospheric
water vapour due to a corresponding
increase in ocean temps and changes in ocean currents, the extreme ice albedo currently happening in the arctic
etc,
etc are all conspiring in tandem to alter the climate as we know it.
To date, while various effects and feedbacks constrain the certainty placed on recent and projected climate change (EG, albedo change, the response of
water vapour, various future emissions scenarios
etc), it is virtually certain that CO2
increases from human industry have reversed and will continue to reverse the downward trend in global temperatures that should be expected in the current phase of the Milankovitch cycle.
In order of seniority, the seven feedbacks that seem outstanding are:
Water vapour — rising by ~ 7 % per 1.0 C of warming; Albedo loss — due mostly to cryosphere decline; Microbial peat - bog decay — due to rising CO2 affecting ecological dynamics; Desiccation of tropical and temperate soils — due to SAT rise and droughts; Permafrost melt — due to SAT rise plus loss of snow cover, etc; Forest combustion — due to SAT rise, droughts, pest responses, etc; Methyl clathrates [aka methane hydrates] now threatened by rising sea - temperatures, increased water column mixing,
