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.
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.
The Greenland Ice Sheet is one of the largest ice sheets in the world. But it might not be for much longer, if Earth continues to warm.
The world's richest man, Amazon.com founder Jeff Bezos, is starting an organization devoted to battling climate change — and he's putting in $10 billion of his own money to get it off the ground.
It's the award no one wanted to win: 2019 was the second hottest year on record, government scientists confirmed yesterday (Jan. 15).
The drainage of meltwater lakes may be making Greenland more unstable than scientists previously realized.
Experts once thought that older, more robust sea ice in the Arctic was mostly safe from melting — but that may not be the case.
Italian officials have ordered the evacuation of mountain huts and closed down roads near the Planpincieux Glacier, which is at risk of collapse.
Beneath the Arctic lie billions of barrels of oil. But as the international energy race intensifies, we wonder, how did all that oil get there in the first place?
Following the hottest June ever recorded, July 2019 may have been the single warmest month in history.
The worst day of melting was July 31, when 11 billion tons of melted ice disappeared into the ocean.
A new study shows that the ice at the bottoms of submerged glaciers could be melting 100 times faster than anyone thought.
From the 800s to the 1400s, about a dozen megadroughts struck the American Southwest, and all lasted longer than a decade.
The global climate is changing more now than at any point in the plast 2,000 years. The Little Ice Age and the Medieval Warm Period were nothing like this.
Wildfires burning large swaths of Russia are generating so much smoke, they're visible from space, new images from NASA's Earth Observatory reveal.
