"Lead radiation shields forced on workers at the stricken Fukushima No. 1 nuclear power plant to cover their dosimeters masked radiation readings by about 30 percent."
"RANJIT NAGAR, India -- When the United Nations wanted to help slow climate change, it established what seemed a sensible system. Greenhouse gases were rated based on their power to warm the atmosphere. The more dangerous the gas, the more that manufacturers in developing nations would be compensated as they reduced their emissions. But where the United Nations envisioned environmental reform, some manufacturers of gases used in air-conditioning and refrigeration saw a lucrative business opportunity."
"DA NANG, Vietnam -- In the tropical climate of central Vietnam, weeds and shrubs seem to grow everywhere -- except here."
"In the Soviet playbook for all-out war with the United States, the wasting of U.S. cities by nuclear bombs was to be followed by something equally horrifying: waves of plagues to kill any survivors.

"It is too early to proclaim the 'ice sheet's future doom'" caused by climate change, lead author Kurt Kjaer of the University of Copenhagen wrote in a statement of the findings in Friday's edition of the journal Science."
As ethnobotanists meet in New York City, they offer reminders that obscure and endangered species should be preserved because they sometimes form the basis of miracle drugs.
"The earth is performing an enormous disposal service for the human race. About half of the carbon we are dumping into the atmosphere does not stay there and is instead taken up by the oceans and land. Were this not the case, scientists say, the earth would probably be warming far more rapidly. One of the biggest questions in climate science is: How long will that disposal service last?"
