Nissan Motor Co plans to launch production of electric vehicles and their batteries in the United States to tap low-interest loans for green vehicles, the Nikkei business daily said. The overall investment is estimated at 50 billion yen ($516.4 million) and may rise to 100 billion yen, it said.

Mars Lake Held as Much Water as Lake Champlain

Nestled in a valley near the Martian equator, scientists have discovered the striking remnants of an ancient lake. Though dry and frigid now, the traces it left behind hint at a water body younger than any other on the planet, and its sediments are a prime target for finding fossilized alien life.

Deutsche Bank has erected a seven-story sign in the heart of New York City that ticks off the tons of carbon dioxide being emitted into the atmosphere — a public relations move designed to raise awareness of global warming.

Rising ocean temperatures near worst-case predictions

The ocean is warming about 50 per cent faster than reported two years ago, according to an update of the latest climate science. A report compiling research presented at a science congress in Copenhagen in March says recent observations are near the worst-case predictions of the 2007 report by the United Nations' Intergovernmental Panel on Climate Change.

NASA Launches Moon Probes to Look for Water

NASA has successfully blasted two probes into space on a landmark lunar exploration mission to scout water sources and landing sites in anticipation of sending mankind back to the moon in 2020. The launch marked "America's first step in a lasting return to the moon," a NASA official said moments after a rocket carrying the probes launched at 5:32 pm (2132 GMT), one day after the US space agency scrubbed the shuttle Endeavour launch for the second time in a week because of a nagging hydrogen fuel leak.

NOAA Forecast Predicts Large "Dead Zone" for Gulf of Mexico this Summer
June 18, 2009 04:19 PM - Editor, ENN

A team of NOAA-supported scientists from the Louisiana Universities Marine Consortium, Louisiana State University, and the University of Michigan is forecasting that the “dead zone” off the coast of Louisiana and Texas in the Gulf of Mexico this summer could be one of the largest on record. The dead zone is an area in the Gulf of Mexico where seasonal oxygen levels drop too low to support most life in bottom and near-bottom waters.

Senate Panel Approves Energy Bill
June 18, 2009 06:26 AM - JOHN M. BRODER, New York Times

A Senate committee on Wednesday approved an energy bill that would open large tracts of the Gulf of Mexico to oil and gas drilling and provide federal loan guarantees for a gas pipeline project in Alaska. The measure, which cleared the Senate Energy and Natural Resources Committee on a 15-to-8 vote, would also require utilities to produce up to 15 percent of electricity from renewable sources like wind and solar power by 2021. That standard is somewhat weaker than one in a House energy and climate change bill that is headed for a floor vote as early as next week.

Scientists Debate Shading Earth As Climate Fix

Engineering our climate to stop global warming may seem like science fiction, but at a recent National Academy of Sciences meeting, scientists discussed some potential geoengineering experiments in earnest.

Global Climate Change Impacts in the United States
June 16, 2009 06:29 PM - Editor, ENN

The US Federal government released a major report today. The report summarizes the science and the impacts of climate change on the United States, now and in the future. It focuses on climate change impacts in different regions of the U.S. and on various aspects of society and the economy such as energy, water, agriculture, and health. The report is the work of 12 federal agencies including the EPA, DOD,COMMERCE, NASA, and others.It’s written in plain language, with the goal of better informing public and private decision making at all levels.

Sediment yields climate record for past half-million years

Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years. The record, trapped within the top 20 meters (65.6 feet) of a 400-meter (1,312-foot) sediment core drilled in 2005 in the North Atlantic Ocean by the Integrated Ocean Drilling Program, gives new information about the four glacial cycles that occurred during that period. New research was presented June 15th at the Chapman Conference on Abrupt Climate Change at Ohio State University's Byrd Polar Research Center. The meeting is jointly sponsored by the American Geophysical Union and the National Science Foundation. Harunur Rashid, a post-doctoral fellow at the Byrd Center, explained that experts have been trying to capture a longer climate record for this part of the ocean for nearly a half-century. "We've now generated a climate record from this core that has a very high temporal resolution, one that is decipherable at increments of 100 to 300 years," he said.
