ABSTRACT — Climate change is expected to cause mass human migration, including immigration across international borders. This study quantitatively examines the linkages among variations in climate, agricultural yields, and people’s migration responses by using an instrumental variables approach. Our method allows us to identify the relationship between crop yields and migration without explicitly controlling for […]
By Wynne Parry, Senior Writer29 July 2010 07:39 am ET One hundred days ago Thursday, the oil rig Deepwater Horizon began spewing oil into the Gulf of Mexico. As profoundly as the leak of millions of barrels of oil is injuring the Gulf ecosystem, it is only one of many threats to the Earth’s oceans […]
Total annual river discharge to the Arctic Ocean from the six largest rivers in the Eurasian Arctic for the observational period 1936–2008 (updated from Peterson et al. 2002) (red line) and from the four large North American pan-Arctic rivers over 1970–2008 (blue line). The least squares linear trend lines are shown as dashed lines. Provisional […]
Scientific evidence that our world is warming is unmistakable has been released today in the 2009 State of the Climate report, issued by US National Oceanic and Atmospheric Administration (NOAA). The report draws on data from 10 key climate indicators that all point to that same finding — the world is warming. The 10 indicators […]
ScienceDaily (July 28, 2010) — A new article published in the 29 July issue of the journal Nature reveals for the first time that microscopic marine algae known as “phytoplankton” have been declining globally over the 20th century. Phytoplankton forms the basis of the marine food chain and sustains diverse assemblages of species ranging from […]
Fingers crossed: it looks like the cap on BP’s Macondo well will hold until the relief well intercepts and permanently plugs it, and no more oil from this blowout will enter the Gulf. So here’s a map showing the cumulative oil slick footprint for the BP / Deepwater Horizon oil spill, created by overlaying all […]
Scientists suspect starvation from changing water temperatures or overfishing after 500 birds found in 10 days Associated Press in São Paulo, www.guardian.co.ukWednesday 21 July 2010 07.41 BST Hundreds of penguins that have apparently starved to death are washing up on the beaches of Brazil, worrying scientists who are investigating what exactly killed them. About 500 […]
A boat made from thousands of plastic bottles has sailed into Sydney Harbour, completing a four-month voyage that began in San Francisco. The boat, called the Plastiki, was built using 12,500 plastic bottles. Its 9,000 mile (15,000 km) voyage aimed to raise awareness of the dangers posed to the environment by plastic waste. Hundreds of […]
By Bonny SchumakerMonday, July 26, 2010 Sea Shepherd Conservation Society’s “aviation wing” has been extremely busy in the Gulf of Mexico for the past couple of months, and especially this past month. In keeping with the strong emphasis being put on collaboration, Sea Shepherd has been working with other NGOs as well as local people […]
Freshwater coastal wetlands are more vulnerable to erosion during hurricanes than habitats with higher levels of salinity, a study suggests. US researchers say freshwater marshes have shallower root systems, leaving them at risk from wave erosion during storm surges. They added that the results could have implications for wetland restoration projects in hurricane-prone areas. The […]
