Indonesian Corals Shed Light on Climate System

A new coral salinity record shows that the location of the most significant hydroclimatic feature in the Southern Hemisphere, the South Pacific Convergence Zone, influences a major Pacific Ocean current.

Shifting Monsoon Altered Early Cultures in China, Study Says

The annual summer monsoon that drops rain onto East Asia has shifted dramatically, at times moving northward by as much as 400 km and doubling rainfall in that northern reach. The monsoon’s changes over the past 10,000 years likely altered the course of early human cultures in China, say the authors of a new study.

Scientists Say They Now Know Why Antarctic Meltwater Stays Below Ocean Surface

Up to now, it has been a mystery why much of the fresh water resulting from the melting of Antarctic ice shelves ends up in the depths instead of floating above saltier, denser ocean waters. Scientists working along one major ice shelf believe they have found the answer.

Ideology and Environmental Protection

With the phrase “climate change” disappearing from U.S. federal government websites and increased talk of regulatory overreach, it is obvious that protecting the environment will continue to be a fault line in American political ideology. However, though ideology will shape the nature and speed of response, the environmental problem is real and cannot be ignored.
