Sweltering temperatures in June capped off a year of record-breaking temperatures across the United States. Whether the trend is an anomaly or the new normal is something scientists are still trying to figure out.
A new study out of Texas Tech University found that all corners of the world aren't in fact equal in terms of how climate change will alter the risk for wildfires. In fact, while the United States will see -- and is seeing -- an increase in wildfires, other parts of the world are in line to see their wildfires decrease.
The carbon dioxide we release is absorbed by the Earth's oceans. But it doesn't just benignly vanish. It's eventually released into the water, making the water more acidic. That's feeding algae blooms and killing some animals. In the Puget Sound, the situation is even worse.
In the last 20 years, the moose population in the northern Midwest has declined. Researchers believe this may be due to climate change and warmer temperatures as well as an increase in the number of predators to moose.
The average annual temperature has risen more in Mongolia than any other place on earth almost, about 4 degrees. The rain patterns have changed. In fact, some 60 to 70 percent of the country is at risk of desertification. If that happens, the country's nomadic herders will have to give up their herds and their traditional way of life.
Scientists who study climate change and ocean environments have made several recent discoveries. Their findings have challenged the conventional wisdom that climate change could eliminate coral reefs. What they've found is that they probably won't disappear, but they will see major changes.
Across the country, an early 2012 heat wave broke into the record books in a big way. According to government data, some 25 states east of the Rocky Mountains had their hottest months ever.
Across the world, scientists are trying to determine where seasons are shifting. Spring arriving earlier, winter arriving later — it's happening in many countries. Now, the question is, what will be the consequences of that change.
Eleven African countries are working to build a green wall of trees on the southern border of the Sahara. Their goal is to fight desertification in the Sahel region.
On Svalbard, in Norway, the farthest north inhabited place on Earth, scientists are at the center of research on climate change. It's also become a magnet for politicians, stars and even royalty who are looking to stake a claim as environmentalists.
