The meek shall inherit the Earth, and that may not be a good thing, if the meek are cyanobacteria. It turns out that the ancient microbes lowest on Earth's food chain are sensitive sorts. Familiar strains of these organisms that provide "biological services" essential to complex life are about to lose the competition for a viable niche in a world turned warmer and more carbon-rich, according to two new studies. And the strains poised to dominate in the desert and ocean remain mysterious and largely unstudied.

When I first read the news last spring that Mayor Antonio Villaraigosa had named S. David Freeman as his deputy mayor for environmental and energy programs, I was sure that H. David Nahai's tenure as general manager at the city utility, the Los Angeles Department of Water and Power, would be short. Fast-forward to now: Nahai has resigned, and the mayor has proposed -- and the commission that oversees the DWP has approved -- Freeman, 83, to be the interim chief for six months. Thus the political musical chairs in the DWP's executive suite continue.

In the early days of the global climate summit, Copenhagen was Christmas incarnate -- a place of white lights, rosy cheeks and cobbled streets, where sugared almonds roasted in great metal bowls and a classical sextet played carols in the cold. By the end, the city was Mordor, the soul-crushing provenance of evil in Tolkien's "The Lord of the Rings." Dreary, gray, slushy. Daylight made timid cameos. In the stark Nordic hotel hosting U.S. negotiators, so newly built that some rooms lacked shower heads, the wind rattled the windows.

A meeting of delegates from the nations that emit the most pollutants ended without fixed targets for slashing greenhouse gas emissions, but participants praised what they saw as a new willingness by the U.S. to discuss possible solutions. Delegates from 16 nations, plus the European Union and the United Nations, gathered in Hawaii this week at the invitation of the United States to discuss what should be included in a blueprint for combating climate change. Delegates didn't discuss the details of a European Union proposal for industrialized countries to slash emissions by 25% to 40%, a European Commission official said.

NASA's inspector general concluded that the agency's press office had "marginalized or mischaracterized" studies on global warming between 2004 and 2006. The report cited "inappropriate political interference" by political appointees in the press office. It said top management wasn't to blame, nor were career officials.

A UC San Diego chemistry center has won $20 million from the National Science Foundation to continue pioneering research on the effects of tiny atmospheric particles on climate. The award, announced Monday, follows a much smaller NSF grant that helped establish the Center for Aerosol Impacts on Climate and the Environment at the university three years ago. Distributed over five years, the funding will underwrite research by a multidisciplinary team of scientists from various institutions who are examining the role that microscopic atmospheric particles called aerosols play in precipitation and other aspects of climate.

Regarding "Utility fees sought for climate think tank," Aug. 26: Carbon dioxide constitutes 3.6% of greenhouse gases. Human activity contributes only 3.3% of all carbon dioxide that enters the atmosphere. That's less than 0.12% of the total. The goal of reducing that amount 25% by 2025 is a costly, useless fantasy, and 10 cents a month from everyone's utility bill for a bogus "climate think tank" is a grand example of too much government meddling.

Re "Civilization's last chance," Opinion, May 11 Scientists estimate that the Earth is about 4.5 billion years old. During that time, the Earth has undergone vast, monumental and violent geologic, tectonic, volcanic and climatic changes. The planet has cooled and warmed, ice ages have come and gone, and natural marvels such as the Grand Canyon and Yosemite Valley were left behind. Entire species have been wiped out, and we don't even know why. In contrast, human beings as we know them have existed for about 200,000 years, and they've been industrialized for a few centuries, a mere blink of an eye compared with the age of the Earth.

Re "Nations Adopt Climate Pact Without U.S.," July 24: Global warming treaty? We don't need no stinkin' global warming treaty. This is America. We should be able to continue to pollute more than any other country--it's our right! Give up our SUVs? That would be too much of a hardship; we shouldn't have to make that kind of sacrifice. It's not "in our best interest" to cut our greenhouse emissions to help save the planet. It's not "in our best interest" to take responsibility and do our part.

In a last-minute turn in global climate talks, international negotiators agreed over the weekend to adopt more ambitious plans than expected to trim government subsidies to oil companies worldwide, part of a broader effort to reduce greenhouse-gas emissions. Earlier this week, negotiators were hammering out an agreement among the top 20 industrialized and emerging nations that called for each to take "voluntary" measures to cut production and consumption incentives. But privately under pressure from the Obama administration over the last two days, the group now is preparing to sign an agreement that omits the word "voluntary."
