Ocean Fertilization 'Fix' For Global Warming Discredited By New Research

Research performed at Stanford and Oregon State Universities suggests that ocean fertilization may not be an effective method of reducing carbon dioxide in the atmosphere, a major contributor to global warming. Ocean fertilization, the process of adding iron or other nutrients to the ocean to cause large algal blooms, has been proposed as a possible solution to global warming because the growing algae absorb carbon dioxide as they grow. >> Read the Full Article

It is too early to sell carbon offsets: scientists

Prof Watson said: "While we do envision the possibility of iron fertilisation as an effective form of carbon offsetting, we believe larger scale experiments are needed to assess the efficiency of this method and to address possible side effects. "There remain many unknowns and potential negative impacts." >> Read the Full Article

South Africa gets nanotech underway

South African scientists are using nanotechnology to develop new healthcare tools, advanced materials and energy technologies. Research is underway at South Africa's first two Nanotechnology Innovation Centres based at Mintek — the country's national mineral research organisation >> Read the Full Article

Severe weight loss caused by chewing gum

In this week’s BMJ, doctors warn of excess sorbitol intake, a widely used sweetener in “sugar-free” products such as chewing gum and sweets. Sorbitol has laxative properties and is poorly absorbed by the small intestine. >> Read the Full Article

Energy Saving Program in Seattle Puts Consumer in Control

Today, the New York Times reports on such a pilot experiment involving 112 homes in the Seattle area. The project by the Pacific Northwest National Laboratory of the Energy Department, showed that ‘if households have digital tools to set temperature and price preferences, the peak loads on utility grids could be trimmed by up to 15 percent a year. Over a 20-year period, this could save $70 billion on spending for power plants and infrastructure, and avoid the need to build the equivalent of 30 large coal-fired plants.’ >> Read the Full Article

World warming despite cool Pacific and Baghdad snow

OSLO (Reuters) - Climate change is still nudging up temperatures in the long term even though the warmest year was back in 1998 and 2008 has begun with unusual weather such as a cool Pacific and Baghdad's first snow in memory, experts said. "Global warming has not stopped," said Amir Delju, senior scientific coordinator of the World Meteorological Organization's (WMO) climate program. >> Read the Full Article

Campaign puts bid to solve climate change ahead

After just two early contests in the 2008 U.S. presidential campaign, some environmental groups are already declaring a winner: the issue of climate change. "Four candidates, two states, one winner," was how the League of Conservation Voters put it after Tuesday's New Hampshire primary victories for Democrat Hillary Clinton and Republican John McCain and Iowa caucus wins for Republican Mike Huckabee and Democrat Barack Obama. >> Read the Full Article

California agency presses EPA on ship exhaust

LOS ANGELES (Reuters) - A Los Angeles-area air quality agency on Thursday petitioned the Environmental Protection Agency to immediately set tougher standards on global-warming pollutants for ocean vessels calling on U.S. ports.

Wal-Mart faces hurdles in green electronics

A campaign to reduce packaging has been a success for Wal-Mart Stores "green" campaign, but a move toward environmentally friendly electronics is proving that changing the mechanics of a TV is much more complex than changing the mechanics of a cereal box. Manufacturers that sell goods in Wal-Mart's stores have responded quickly to the company's request to cut packaging waste, slashing the size of cereal boxes or bulking up toilet paper rolls to eliminate the need for extra cardboard centers. >> Read the Full Article

Glaciers grew even when alligators lived in Arctic

Giant glaciers formed about 90 million years ago when alligators thrived in the Arctic, overturning the belief that all ice melts in a "super greenhouse" climate, researchers said on Thursday. The study, based on organic molecules in ocean sediments and chemicals in ancient fossil shells, indicated there were ice sheets in Antarctica during parts of the Turonian period, one of the warmest times in history when dinosaurs roamed the planet. >> Read the Full Article
