You further presume that it is essential to «mitigate» climate change which by default castigates as «denier» all who accept your anthropogenic majority global warming, yet who find the economics of «mitigation» incredibly bad and the concept morally reprehensible.

According to UN Environment, existing commitments by nations fall well short of what is needed to meet warming targets and emissions will not fall quickly until the world undertakes much more ambitious mitigation actions.

One thing that stopped me in my tracks was an image - the photo of smog in China - and I invite you to visit www.thegreatwarming.com to see what we've been able to accomplish by combining solid science from IPCC, NOAA, NCAR, ICC and more with visually arresting global stories about warming and mitigation efforts.

Since warming is not occuring at the predicted rate, any changes that do occur can be adapted to by humans more cost effectively and with lower risk than through CO2 mitigation activities.

Their purpose is to assist in the mitigation of global warming by compensating or «offsetting» an emissions - producing activity by investing into offsets that improve efficiency, conserve energy and biodiversity, and change in behaviour.

Using these data supplied by IPCC, we can now back - calculate the amount of warming we could theoretically avert with other mitigation actions, again using the IPCC climate sensitivity of 3.2 °C.

Then, at the minimum 5 % market inter-temporal discount rate, the cost of trying to abate this decade's predicted warming of 0.15 Cº by typical CO2 - mitigation schemes as cost - ineffective as Australia's carbon tax would be 48 times greater than the cost of later adaptation.

I've spent my whole professional life working on climate change and would prefer it if we could deal with global warming by mitigation alone.

Rice cultivation regions show reduced warming as they are concentrated where monsoon rainfall is projected to intensify, although projections are influenced by Asian aerosol loading in climate mitigation scenarios.

The link between adverse impacts such as more wildfires, ecosystem changes, extreme weather events etc. and their mitigation by reducing greenhouse gas emissions hinges on detecting unusual events for at least the past century and then actually attributing them to human caused warming.

The instabilities in the climate system and the movement from global warming to global heating kicks in above 350 ppm, so that as the ppm increase, mitigation opportunities are lost and catastrophic harms on an even grander grand scale (as noted by Mike) will continue to occur to human and other life forms.

Mitigation plans proposed by governments would slow down the rate of carbon emissions but continuing emissions as well as feedbacks from ice melt, warming oceans, methane release and fires would continue to push temperatures upwards.

Summary of how they got to this finding: They use CMIP models which, if not outright flawed, have not proved their validity in estimated temperature levels in the 2030 to 2070 timeframe, are used as the basis for extrapolations that assert the creation of more and more 3 - sigma «extreme events» of hot weather; this is despite the statistical contradiction and weak support for predicting significant increases in outlier events based on mean increases; then, based on statistical correlations between mortality and extreme heat events (ie heat waves), temperature warming trends are conjured into an enlargement of the risks from heat events; risks increase significantly only by ignoring obvious adjustments and mitigations any reasonable community or person would make to adapt to warmer weather.
