If the human population continues to grow, more pressure will be put on carbon dioxide emissions — leaving future generations vulnerable to the effects of climate change.
China is rapidly expanding its solar power supply, hoping to meet 10 percent of the nation’s electricity needs with solar energy by 2030. But there’s a problem: Severe air pollution is blocking light from the sun, significantly reducing China’s output of solar energy, particularly in the northern and eastern parts of the country.
In the mid-1990s, 1,000 truckloads of orange peels and orange pulp were purposefully unloaded onto a barren pasture in a Costa Rican national park. Today, that area is covered in lush, vine-laden forest.
Unmitigated climate change will make the United States poorer and more unequal, according to a study published June 29 in the journal Science. The poorest third of counties could sustain economic damage costing as much as 20 percent of their income if warming proceeds unabated.
Scientists and policymakers use measurements like global warming potential to compare how varying greenhouse gases, like carbon dioxide and methane, contribute to climate change.
Severe air pollution has plagued China's industrial regions in recent decades, a situation that has received worldwide attention thanks to photos of Beijing and other smog-blanketed Chinese cities.

Issues related to the environment and climate change will demand the new president's attention soon after he or she takes office Jan. 20 and throughout the next four years.
Beijing and surrounding areas of China often suffer from choking smog. The Chinese government has made commitments to improve air quality and has achieved notable results in reducing emissions from the power and transportation sectors.
