The total annual area occupied by overwintering monarch butterflies from 1994 through 2011 has declined significantly, with the all-time smallest area reported during the 2009–10 overwintering season. The dashed line shows the 17-year average (7.24 ha). Both linear (upper) and exponential (lower) regression lines are included. Abstract: During the 2009–2010 overwintering season and following a 15-year […]
Urban air pollution is set to become the top environmental cause of mortality worldwide by 2050, ahead of dirty water and lack of sanitation. The number of premature deaths from exposure to particulate air pollutants leading to respiratory failure could double from current levels to 3.6 million every year globally, with most occurring in China […]
HeadsUp!

By Charlie Smith 19 March 2012 A Japanese citizen watchdog has reported that cesium-137 levels rose more than five times in Fukushima over a 24-hour period between March 15 and 16. The online Fukushima Diary pointed out that there were no megabecquerels per square kilometre of cesium-137 detected between March 8 and March 11. But […]
グレイは放射線が物質に当たった時のエネルギー量を表し、大気中の放射線量１グレイは１シーベルトに換算できます。 【参考】健康安全研究センターで平常時に観測されていた測定値：１時間あたり0.028～0.079マイクロシーベルト（平均値は概ね、0.035マイクロシーベルト／時）で推移＜上記の緑色の帯の範囲＞。 Machine translation: Grey represents the amount of energy when radiation hits the material, you can convert the atmospheric radiation 1 gray dose of 1 sievert. [Wikipedia: The gray (symbol: Gy) is the SI derived unit of absorbed radiation dose of ionizing radiation (for example, X-rays), and is defined as the absorption of one […]
We use a Lagrangian particles dispersal method to track where free floating material (fish larvae, algae, phytoplankton, zooplankton…) present in the sea water near the damaged Fukushima Daiichi nuclear power station plant could have gone since the earthquake on March 11th. THIS IS NOT A REPRESENTATION OF THE RADIOACTIVE PLUME CONCENTRATION. Since we do not […]
SYDNEY, 14 March 2012 (AFP) – Australia’s climate is warming at an alarming rate and is set to become drier despite recent record floods, scientists said Wednesday in a report that warns of increased drought and fiercer storms. The country has seen annual average daily temperatures rise by 0.9 degrees Celsius since 1911, with each […]
Paris (AFP) 7 March 2012 – Water management needs urgent reform if the world is to head off serious deterioration in the quality and quantity of water available. At the release of the OECD’s Meeting the Water Reform Challenge, OECD Secretary-General, Angel Gurría warned that ,“Without major policy changes, we risk high costs to economic […]
Areas that will experience more than a 5% reduction in length of growing period (LGP). LGP is defined by the average number of growing days per year, in which a growing day is one in which the average air temperature is greater than 6°C and the ratio of actual to potential evapo-transpiration exceeds 0.35 (Jones […]
28 February 2012 (Brookings) – As 2012 begins, a growing number of Americans believe global warming is occurring. This is one of the key findings from the latest National Survey of American Public Opinion on Climate Change (NSAPOCC). Other highlights include: More Americans than ever are pointing to experiences with warmer temperatures as the main […]
