As the ice caps on Baffin Island shrink, the landscape beneath is seeing the light of day for the first time in perhaps 120,000 years. Here’s a look at the stark and humbling beauty.
Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. There is great debate among many people, and sometimes in the news, on whether global warming is real (some call it a hoax). But climate scientists looking at the data and facts agree the planet is warming.While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years.Scientists from the Intergovernmental Panel on Climate carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 °C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events.
Donald Trump's tweets notwithstanding, climate change could lead to a worst-case scenario of extreme snow storms against a backdrop of less snowpack overall.
In the coming decades, more than a quarter-million people may die each year as a result of climate change, according to a new review study.
Ocean temperatures reached their highest point since accurate measurements first began in the 1950s.
Echoes of the Little Ice Age still persist more than a mile down in the Pacific Ocean, even as ocean warming looms.
Greenhouse gases are atmospheric gases that absorb infrared radiation and trap heat in the atmosphere. Increases in emissions of these gases are leading to climate change and global warming.
More than 8.5 million acres of land in the U.S. burned this year. Here's how the raging flames get their start.
Why did megalodon go extinct? New research has answers, and the shark's high body temperature likely played a part.
