Using climatological salinities (World Ocean Atlas available from NOAA NODC at http://www.nodc.noaa.gov) and NOAA SSTOI, we extended this approach to model fields back through 1988 (Figure 2b), revealing regionally averaged Ωar values declining at a rate of about 3% per decade amid considerable seasonal variability. These values are consistent with in situ measurements obtained at […]
By Michael PerryTue Jan 5, 2010 9:24am EST SYDNEY (Reuters) – Australia experienced its hottest decade on record from 2000 to 2009 due to global warming, the nation’s bureau of meteorology said on Tuesday, as annual summer bushfires again burn drought lands and destroy homes. The average temperature in Australia over the past 10 years […]
This visualization is a time-series of the global distribution and variation of the concentration of mid-tropospheric carbon dioxide observed by the Atmospheric Infrared Sounder (AIRS) on the NASA Aqua spacecraft. For comparison, it is overlain by a graph of the seasonal variation and interannual increase of carbon dioxide observed at the Mauna Loa, Hawaii observatory. […]
In 2010, many nations in the currency bloc will attempt to shore up finances and sustain fitful economic recoveries By TERENCE ROTH After two years of crashing banking systems and economic recession, the euro zone enters 2010 with a full-blown debt crisis. The European Commission warns that public finances in half of the 16 euro-zone […]
By Hana Namrouqa (MENAFN – Jordan Times) With people in over 17 Arab countries living well below the water poverty line of 500 cubic metres annually, Arab decision makers on Monday called for coordinated efforts to address the impact of climate change on the limited resource. Experts said more than 75 per cent of the […]
By Steve Gorman, Wed Dec 23, 2009 8:14pm EST LOS ANGELES (Reuters) – Earth’s various ecosystems, with all their plants and animals, will need to shift about a quarter-mile per year on average to keep pace with global climate change, scientists said in a study released on Wednesday. How well particular species can survive […]
Water-level changes in the High Plains aquifer, predevelopment to 2007 (modified from Gutentag and others, 1984; Lowry and others, 1967; Luckey and others, 1981; and Burbach, 2007). The High Plains aquifer underlies 111.6 million acres (174,000 square miles) in parts of eight States—Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. Water-level declines […]
Due to the current El Niño event, above‐average rainfall was forecast for the areas of East Africa that receive October to December rains. These rains were expected to contribute to a reduction in the high to extreme levels of food insecurity that have affected many parts of the region following several consecutive failed rainy seasons. […]
Much of the U. S. has been warmer in recent years, and that affects which trees are right for planting. The Arbor Day Foundation has recently completed an extensive updating of U.S. Hardiness Zones based upon data from 5,000 National Climatic Data Center cooperative stations across the continental United States. Hardiness Zone Changes Between 1990 […]
Organic carbon (OC) concentrations in the Zuoqiupu ice core for the monsoon (June–September) and nonmonsoon (October–May) seasons, and for the annual mean. Fig. 3 shows the Zuoqiupu data broken down by monsoonal and nonmonsoonal periods. The monsoonal period has lower BC and OC concentrations because of the high precipitation rate, but the source is unambiguously […]
