So if the actual temperature was close to «Scenario C» (which it was), this shows that all the CO2 that has been emitted since 2000 plus half of what was emitted between 1990 and 2000 have had no impact on global temperature at all.

Even under optimistic assumptions about global carbon abatement, the Earth is expected to warm by 4oC or more by the end of the century, making it hotter than it has been for 15 million years, and crossing several tipping points along the way that will make it impossible to stabilise the global temperature at any level.

The only «tipping point» we need be concerned with is the level of global temperature at which warming switches to cooling and vice versa.

Targets for limiting global warming thus, at minimum, should aim to avoid leaving global temperature at Eemian or higher levels for centuries.

changes to atmospheric CO2 concentration FOLLOW changes to global temperature at all — yes, all — time scales, and a cause can not follow its effect,

No, it translates to climate models can not accurately represent natural climate variability, which is why they can't project future global temperature at even the 2 % confidence level: «we find that the continued warming stagnation of fifteen years, 1998 - 2012, is no longer consistent with model projections even at the 2 % confidence level» — vonStorch (2013)

Thus, the concept of an emissions budget is very useful to get the message across that the amount of CO2 that we can still emit in total (not per year) is limited if we want to stabilise global temperature at a given level, so any delay in reducing emissions can be detrimental — especially if we cross tipping points in the climate system, e.g trigger the complete loss of the Greenland Ice Sheet.

So you might expect those same environmentalists to be rather excited by a project that claims to be able to stabilise global temperatures at the push of a button, and keep them stable while the world makes the transition to energy sources of the future.

Geologist Dr. Don J. Easterbrook, Emeritus Professor at Western Washington University, who has authored eight books and 150 journal publications, predicts that temperatures should cool between 2065 until 2100, and that global temperatures at the end of the century should be less than 1 degree cooler than at present.

At normal concentrations, it, along with other greenhouse gases, helps maintain global temperatures at...

Much of their seminal research has been exposed as academic fraud, based on cute little games like ignoring large periods of history that don't conform to their man - made climate change models, fudging temperature measurements, and changing the methodology for recording and estimating global temperatures at during different historical periods.

Yes, such processes involve redistribution of heat, but heat redistributed from or to ocean depths to the surface would affect global temperatures at these time scales, whereas (as you imply) geographical redistribution at the surface would not (or at least much less).

If nothing is done to reverse the current situation, we could miss our chance to limit the concentration of greenhouse gases in the atmosphere to approximately 450 parts per million of CO2 — a level that would cap rising global temperatures at 2ºC.

Molden said that based on recent research, limiting average global temperatures at a 2 degree Celsius rise from pre-industrial levels — as envisaged by the historic Paris accord of 2015 — in the world means 3 to 4 degrees of warming in the mountains, while limiting average global temperature rise to 1.5 degree Celsius would mean a 3 degree Celsius rise in high - altitude areas.

Most scientists and climatologists agree that weird weather is at least in part the result of global warming — a steady increase in the average temperature of the surface of the Earth thought to be caused by increased concentrations of greenhouse gasses produced by human activity.

Climate scientists tell us that to keep the rise of global temperature above the pre-industrial level at below 1.5 degrees Celsius (2.7 degrees Fahrenheit) in order to avoid runaway global warming, the world must cut greenhouse gas emissions by 15 percent per year starting in 2020.
