Greenhouse Gases Make High Temps Hotter in China

To be fair, note that China has the largest population of any country.
1 China 1,339,190,000
2 India 1,184,639,000
3 United States of America 309,975,000

And the last time I checked, the U.S. still has the largest carbon footprint per person.

China, the world's largest producer of carbon dioxide, is directly feeling the man-made heat of global warming, scientists conclude in the first study to link the burning of fossil fuels to one country's rise in its daily temperature spikes.

China emits more of the greenhouse gas than the next two biggest carbon polluters — the U.S. and India — combined. And its emissions keep soaring by about 10 percent per year.

While other studies have linked averaged-out temperature increases in China and other countries to greenhouse gases, this research is the first to link the warmer daily hottest and coldest readings, or spikes.

Those spikes, which often occur in late afternoon and the early morning, are what scientists say most affect people's health, plants and animals. People don't notice changes in averages, but they feel it when the daily high is hotter or when it doesn't cool off at night to let them recover from a sweltering day.

The study by Chinese and Canadian researchers found that just because of greenhouse gases, daytime highs rose 0.9 degree Celsius (1.7 degrees Fahrenheit) in the 46 years up to 2007. At night it was even worse: Because of greenhouse gases, the daily lows went up about 1.7 degrees Celsius (3 degrees Fahrenheit).
