Models indicate trade winds will continue to abate in the future as the climate warms, Karnauskas said.

But results from a Canadian government climate modeling study published last month suggest that «it is unlikely that warming can be limited to the 2 ˚C target,» the scientists who wrote the study say.

But the models also suggest that the scheme could go too far: Adding excess sulfur could increase ice in Antarctica, «overcompensating» for warming, says Rasch, which could affect ecosystems and the global ocean - atmosphere system in a myriad of ways that scientists haven't studied.

«Climate sceptics like to criticize climate models for getting things wrong, and we are the first to admit they are not perfect, but what we are finding is that the mistakes are being made by those models which predict less warming, not those that predict more,» said Prof. Sherwood.

«As Earth continues to warm, it may be approaching a critical climate threshold beyond which rapid and potentially permanent — at least on a human time - scale — changes not anticipated by climate models tuned to modern conditions may occur,» the report says.

Climate change models predict that the Arctic sea ice will continue to shrink in a warming world (as much as 40 % of the ice is expected to be gone by midcentury), and the resulting changes — including later formation of ice in the autumn, rain falling on the snow, and decreasing snow depths — will make it increasingly difficult for the seals to construct their snow caves, NOAA says.
