Global warming caused by greenhouse gases delays natural patterns of glaciation, researchers say
The Earth's current warm period that began about 11,000 years ago should give way to another ice age within about 1,500 years, according to accepted…
Drop in carbon dioxide levels led to polar ice sheet, study finds
The key role of the greenhouse gas in one of the biggest climate events in Earth's history supports carbon dioxide's importance in past climate change and…
Growing Something out of Nothing
Fears of global warming and its impact on our environment have left scientists scrambling to decrease levels of atmospheric carbon we humans produce. Now, Tel…
Model shows polar ice caps can recover from warmer climate-induced melting
In recent years scientists have closely monitored the shrinking area of the Arctic covered by sea ice in warmer summer months, a development that has created…
Climate Change Reducing Ocean’s Carbon Dioxide Uptake
As one of the planet’s largest single carbon absorbers, the ocean takes up roughly one-third of all human carbon emissions, reducing atmospheric carbon dioxide…
Succulent plants waited for cool, dry Earth to make their mark
Brown University biologists and colleagues have determined that cacti exploded onto the global scene then, about the same geologic time as other succulent…
