Some 'improved cookstoves' may emit more pollution than traditional mud cookstoves
The first real-world, head-to-head comparison of "improved cookstoves" (ICs) and traditional mud stoves has found that some ICs may at times emit more of the worrisome "black carbon," or soot, particles that ...

Urban 'heat island' effect is a small part of global warming; white roofs don't reduce it
Cities release more heat to the atmosphere than the rural vegetated areas around them, but how much influence these urban "heat islands" have on global warming has been a matter of debate. Now a study by Stanford researchers ...
