BERKELEY, Calif. — Studying the environment would be simple if it weren’t for one thing: Even an isolated ecosystem is unbelievably complicated. Factors to study include water systems, plant life cycles, carbon dioxide fluctuations, resource use by humans, and far more — and each can be studied at the scale of a plant or of the planet, and measured in an instant or over decades.

*Precipitation-controlling aerosols over the Amazon rainforest originate from the forest ecosystem*

A team of environmental engineers, who might better be called “archeologists of the air,” have, for the first time, isolated aerosol particles in near pristine pre-industrial conditions.

Potomac River: Ten-fold Increase in Native Submerged Vegetation Reflects Improved Water Quality

The Potomac River in Washington, D.C. is showing multiple benefits from restoration efforts, newly published research suggests. Reduced nutrients and improved water clarity have increased the abundance and diversity of submerged aquatic vegetation (SAV) in the Potomac, according to direct measurements taken during the 18-year field study.

Ocean’s Color Affects Hurricane Paths

WASHINGTON — A change in the color of ocean waters could have a drastic effect on the prevalence of hurricanes, new research indicates. In a simulation of such a change in one region of the North Pacific, the study finds that hurricane formation decreases by 70 percent. That would be a big drop for a region that accounts for more than half the world’s reported hurricane-force winds.

A new study shows the Arctic climate system may be more sensitive to greenhouse warming than previously thought, and that current levels of Earth’s atmospheric carbon dioxide may be high enough to bring about significant, irreversible shifts in Arctic ecosystems.

Shrinking Arctic sea ice

By ShamsJune 14, 2008EnvironmentArctic sea ice, ecosystem, frozen-soil, permafrost

In 2007 Arctic sea ice shrank to 30% below the average line, which could be the reason of more than 2°C rise of autumn temperature than usual over the land. As the rapid loss of ice severely affects the inland temperature, it will possibly thaw the permafrost (the frozen soil).

Hello to ‘Anthropocene’ or still in Holocene!!

‘Anthropocene’ is probably the first human induced geological time unit in Earth’s history.

Human induced!! …….because it’s all about climate changes and its consequence on the ecosystem. Anthropocene (Greek word ‘Anthropo’ means
