DOI: 10.1126/science.adk3705 An interesting approach to palaeo-temperature modelling – produced by assimilating observational data during the last 485 million years with climate model predictions. This paper introduces a »
Mapped Arctic sea ice extent (SIE) on 09/02/2020 was 14.69 million km2 which is 270,000 km2 or 1.8% less than the 1979-2019 average. This is largest sea ice extent on this day since 2009 and is within 1 standard deviation of the 1979-2019 mean ice extent. »
Over the last 20 years at least there have been near continuous press reports of the near-term disappearance of the Maldives, a series of coral atolls in the Indian Ocean. The chain of 26 atolls stretches from Ihavandhippolhu Atoll in the north to Addu Atoll in the south with an »
January 11, 2020 Mapped Arctic sea ice extent (SIE) on this date was 13.34 million km2 which is 560,000 km2 or 4% less than the 2008-2018 median. This is largest sea ice extent on this day since 2016 The extent of Arctic sea ice varies from summer to winter. The sea »
Of recent times all the reporting on Australia has been little more than dire warnings and catastrophic coverage. There is however some positive news on the horizon. Australia’s climate is determined in large part by three major atmospheric circulatory systems, the Indian Ocean Dipole (IOD) the El Nino – Southern »
The bushfire drama in Australia has subsided for the moment so now is a good time to take stock. As of 7/1/2020, the bushfires have devastated an area in Victoria and New South Wales of 49,600 km2. In eastern Victoria the total burnt area was 12,100 km2 while in New »
January 4, 2020 Mapped Arctic sea ice extent (SIE) on this date was 13.12 million km2 which is 430,000 km2 or 3% less than the 2008-2018 median. This is largest sea ice extent on this day since 2014 and the 12th highest since 2000. We predict maximum SIE of »
January 3, 2020 Mapped Arctic sea ice extent (SIE) on this date was 13.176 million km2 which is 280,000 km2 or 2% less than the 2008-2018 median. This is largest sea ice extent since 2012 and the 12th highest since 2000. Sea ice is steading growing in the Bearing and »
As can be seen in the above graphic, isotopic data derived from ice-cores, deep-sea sediment sediments and other proxies shows dramatic and a characteristic “saw-tooth” signature over the Pleistocene (1.2 million years). For a compilation of the same oxygen isotope and other data over the last 2.7 million years (which »
