Projected annual changes in dryness assessed from change in annual maximum number of consecutive dry days (CDD, days with precipitation <1 mm). Increased dryness is indicated with yellow to red colors; decreased dryness with green to blue. Projected changes are expressed in units of standard deviation of the interannual variability in the three 20-year periods […]
By John Vidal, environment editor, www.guardian.co.uk 1 December 2011 We are right on the equator, and Speke, Moebius, Elena, Savoia, and Moore, the five great glaciers of the the Rwenzori, the Mountains of the Moon, glint in the bright Ugandan sun. Usually lost in the mists that cloak these peaks up to 5,100 metres high, […]
In the long-term, the Reference case projects increased world consumption of marketed energy from all fuel sources through 2035. Fossil fuels are expected to continue supplying much of the energy used worldwide. Although liquid fuels—mostly petroleum based—remain the largest source of energy, the liquids share of world marketed energy consumption falls from 34 percent in […]
By Morgan Kelly15 November 2011 Princeton University – The first climate study to focus on variations in daily weather conditions has found that day-to-day weather has grown increasingly erratic and extreme, with significant fluctuations in sunshine and rainfall affecting more than a third of the planet. Princeton University researchers recently reported in the Journal of […]
By David A Gabel, ENN28 November 2011 As Earth’s climate has warmed, one group of species that has not fared well has been corals, the sedentary marine species which lives symbiotically with algae. Warmer waters cause the algae to become heat-stressed, causing them to die or be expelled by the coral. This causes coral bleaching, […]
Relative composition of the periphytic diatom assemblages along the CO2 gradient, including all genera present over 1% and with all unidentified diatoms grouped as unidentified pennate or naviculoid. Between September 2009 and October 2010, mean surface seawater pH decreased with increasing proximity to CO2 vents (S1 = 8.18, S2 = 8.05, S3 = 7.49, n […]

November 24 (mongabay.com) – Recent arctic sea ice loss is ‘unprecedented’ over the past 1,450 years, concludes a reconstruction of ice records published in the journal Nature. The study, which was led by Christophe Kinnard of Chile’s Centro de Estudios Avanzados en Zonas Aridas, used terrestrial proxies including ice cores, lake sediments, tree ring data, […]
a, Krill density in the SW Atlantic sector (4,948 stations in years with >50 stations). Temporal trends include b, post-1976 krill data from scientific trawls; c, 1926–2003 circumpolar salp data south of the SB. Regressions of log10(mean no. m-2) on year were calculated for cells with ≥3 years of data, weighted by number of stations […]
Hubbert said, “The third curve (on the left) is simply the mathematical curve for exponential growth. No physical quantity can follow this curve for more than a brief period of time. However, a sum of money, being of a nonphysical nature and growing according to the rules of compound interest at a fixed interest rate, […]
