The green, orange and yellow lines indicate how surface temperatures will likely respond if leading carbon emitters begin to reduce reliance on fossil fuels. Without immediate curbs, temperatures are set to follow the red track, and increase between 3.2 and 5.4 degrees Celsius by 2100. The green line shows how we can minimize warming if ...
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
Last year was the warmest year on record, and the first with a global average temperature of more than 1.5 degrees Celsius above the pre-industrial levels. At current rates of warming, 2 degrees ...
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
In January 2011, eleven papers and three introductory articles resulting from the conference were published as a special issue of Philosophical Transactions of the Royal Society, Four degrees and beyond: the potential for a global temperature increase of four degrees and its implications. [5] [6] Many of the papers are free downloads. The ...
Earth has experienced 12 consecutive months of warming at or above 1.5 degrees Celsius — a threshold for avoiding the worst effects of climate change.
As a result the UN Framework Convention on Climate Change predicts a likely increase between 2.1 and 2.9 °C in temperature by 2100, exceeding the 2 °C climate target. [9] Some scientists suggest that the development of decarbonization technologies may offer a way to reverse the accumulation of CO 2 in the atmosphere.
The Doomsday Clock is seen at 89 seconds to midnight, the closest the clock has ever been to midnight in its 78-year history. / Credit: SAUL LOEB/AFP via Getty Images
