Data sets used to monitor the Earth's climate indicate that the surface of the Earth warmed from 1910 to 1940, cooled slightly from 1940 to 1970, and then warmed markedly from 1970 onward. The weak cooling apparent in the middle part of the century has been interpreted in the context of a variety of physical factors, such as atmosphere

Authigenic carbonates within the Reynella Member of the glacial Elatina Formation occur in coastal cliff exposures of the Marinoan type section in South Australia and provide constraints on the magnitude and timing of methane influence during deglaciation.

The humble bucket turns out to be at the bottom of a perplexing anomaly in the climate records for the twentieth century. The time series of land and ocean temperature measurements, begun in 1860, shows a strange cooling of about 0.3

New results show that the response of marine organisms to ocean acidification varies both within and between species.

Grind it down, pour in a sprinkle here and a dash there, and wait for results. That's the recipe for helping the oceans to absorb more of our carbon dioxide emissions: add limestone. It may not only help reduce global warming but could even reinvigorate ailing coral reefs.

Increasing quantities of atmospheric anthropogenic fixed nitrogen entering the open ocean could account for up to about a third of the ocean's external (nonrecycled) nitrogen supply and up to ~3% of the annual new marine biological production, ~0.3 petagram of carbon per year. This input could account for the production of up to ~1.6 teragrams of nitrous oxide (N2O) per year.

A new paper shows that regional and even global temperatures are being temporarily held down by a natural jostling of the climate system, driven in large part by vacillating ocean currents.
