Annual emissions of carbon from changes in land use (Note P = 1015).20 Virtually all of the carbon released to the atmosphere from land use changes now comes from the tropics. Tropical deforestation, including logging and the permanent and temporary conversion of forests to croplands and pastures, releases about 1-2 PgC/yr. This is 15-35% of […]
By PATRICK REYNOLDS, www.IrishCentral.com Staff WriterPublished Friday, November 27, 2009, 9:23 PMUpdated Friday, November 27, 2009, 10:44 PM Ireland’s massive flooding has almost certainly been the result of climate change, says Nobel Prize-winner and Ireland’s leading climatologist, Prof. John Sweeney. “We have reaped what we have sown,” he said. Devastating floods have swept large parts […]
This graph shows the uptake history over the industrial era (ad 1765 to ad 2008) computed from the time-varying inventory. (The corresponding space- and time-varying change in surface disequilibrium of CO2 driving this uptake is also estimated by our inversion method.) There has been a sharp increase in ocean uptake since the 1950s in response […]
By Staff WritersGeneva (AFP) Nov 23, 2009 Greenhouse gas emissions have kept increasing, reaching a record level since the pre-industrial era, the UN climate agency warned Monday, just weeks before a crucial climate change summit. “Levels of most greenhouse gases continue to increase,” said the World Meteorological Organisation in a statement. “In 2008, global concentrations […]
Thermokarst lakes appear on thawing permafrost soil in northeast Siberia in August 2007. For thousands of years, layers of animal and plant waste have been sealed inside the frozen permafrost. Now climate change is thawing the permafrost and lifting this prehistoric ooze from suspended animation. Russian scientists believe that this organic matter will significantly accelerate […]
Greenhouse gas emissions from vehicles, power stations and industries far to the south are putting shellfish in the Arctic Ocean at risk, an international team reports in the Nov. 20 edition of the journal Science. Acidification may put “some species at risk,” the researchers said, saying this could have a major impact on the entire […]
By James Murray, BusinessGreen, Monday 23 November 2009 at 14:24:00 The world is dangerously close to climatic “tipping points” that could result in catastrophic environmental, social and economic consequences, according to a major new study commissioned by the WWF and global insurance giant Allianz. The report from the UK’s Tyndall Centre warns that, unless carbon […]
MOSCOW (AFP) — Thawing permafrost caused by global warming is costing Russian energy firms billions of dollars annually in damage control and shrinking Russia’s territory, Greenpeace warned in a new study Friday. According to the report by the environmental watchdog, up to 55 billion roubles (1.9 billion dollars) a year is spent on repairs to […]
Fish reared in water acidified by CO2 may become “fatally attracted” to the smell of their predators, say scientists. A team studying the effects of acidification – caused by dissolved CO2 – on ocean reefs found that it leaves fish unable to “smell danger”. Young clownfish that were reared in the acidified water became attracted […]
This graph shows the evolution of the various sources and sinks of anthropogenic CO2 between ad 1765 and ad 2005. Our results indicate that the terrestrial biosphere was a source of Cant until the 1940s, roughly in line with previous model-based estimates3, 18, after which it turned into a sink of anthropogenic CO2. Taken over […]
