By Jeremy Hance, www.mongabay.comJanuary 24, 2010 From 2003-2006, Java lost approximately 2,500 hectares a year (10,000 hectares of forest in total) according to the Forestry Ministry. Despite the rate of loss being far lower in Java than other Indonesian islands (such as Borneo, Sumatra, and Sulawesi), Java is particularly threatened because there is so little […]
A sweeping 15-year study of pH levels in the Pacific Ocean confirmed that upper reaches of the sea are becoming increasingly more acidic. By Sandi Doughton, Seattle Times science reporter The most extensive survey of pH levels in the Pacific Ocean confirms what spot measurements have suggested: From Hawaii to Alaska, the upper reaches of […]
By GAYATHRI VAIDYANATHAN of ClimateWirePublished: January 15, 2010 Tree death rates could increase globally because of rising temperatures and prolonged droughts linked to climate change, according to multiple studies. The reasons for tree mortality in a warmer, drier world have been narrowed down to three main scenarios — greater prevalence of insects and diseases in […]
Iron-poor oceans may cause populations of phytoplankton — a critical base of the marine food chain — to decline. By Jessica Marshall | Thu Jan 14, 2010 09:55 AM ET Rising acid levels in the world’s oceans appear to be robbing the tiny animals that form the bedrock of the marine food web of a […]
The treeless ecosystem of mosses, lichens, and berry plants is giving way to shrub land and boreal forest. As scientists study the transformation, they are discovering that major warming-related events, including fires and the collapse of slopes due to melting permafrost, are leading to the loss of tundra in the Arctic. By Bill Sherwonit During […]
Last year, B.C.’s forests were praised in the climate-change fight. But the pine beetle has forced the province to rethink its forest policy By Justine Hunter Victoria — From Saturday’s Globe and Mail Published on Friday, Jan. 08, 2010 7:54PM EST Last updated on Saturday, Jan. 09, 2010 4:31PM EST In a single season, an […]
(University of Colorado at Boulder) Contrary to conventional belief, as the climate warms and growing seasons lengthen subalpine forests are likely to soak up less carbon dioxide, according to a new University of Colorado at Boulder study. As a result, more of the greenhouse gas will be left to concentrate in the atmosphere. “Our […]
An extended time series of the regional mean aragonite saturation state for the Greater Caribbean Region derived using the NOAA extended reconstructed SST (ER SST V3b; red curve) with the Experimental Ocean Acidification Product Suite v0.3 values derived from satellite SST overlaid (blue curve). The global mean (green curve) is estimated from the representative SST […]
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 […]
