If climate change gets catastrophic — and the world sees more than 6 degrees Celsius warming of average temperatures — the planet will have left the current geologic period, known as the Quaternary and a distant successor to the Ordovician, and have returned to temperatures last seen in the Paleogene period more than 30 million years ago.

A favourite climate contrarian talking point is that there was a pause or «hiatus» in warming from 1998 until the early part of the current decade.

That CO2 then warmed the globe, melting back the continental ice sheets and ushering in the current climate that enabled humanity to thrive.

Starting from the same kernel of scientific truth as did The Day After Tomorrow — that global warming could disrupt ocean currents in the North Atlantic — a study commissioned by the Pentagon, of all organizations, concluded that the «risk of abrupt climate change... should be elevated beyond a scientific debate to a U.S. national security concern.»

Climate model projections neglecting these changes would continue to overestimate the radiative forcing and global warming in coming decades if these aerosols remain present at current values or increase.

Current models don't suggest that this factor will increase as the climate warms, but the new study shows that it has in recent years.

Extreme weather does not prove the existence of global warming, but climate change is likely to exaggerate it — by messing with ocean currents, providing extra heat to forming tornadoes, bolstering heat waves, lengthening droughts and causing more precipitation and flooding.

«Having said all that,» said Larsen, «the current climate could slow down the advance of Yahtse or it could stop it a lot sooner than it would if we didn't have this warming trend going on right now.»

Unexpectedly, this more detailed approach suggests changes in Antarctic coastal winds due to climate change and their impact on coastal currents could be even more important on melting of the ice shelves than the broader warming of the ocean.

«When we included projected Antarctic wind shifts in a detailed global ocean model, we found water up to 4 °C warmer than current temperatures rose up to meet the base of the Antarctic ice shelves,» said lead author Dr Paul Spence from the ARC Centre of Excellence for Climate System Science (ARCCSS).
