The date shown when humanity reaches 1.5°C will move closer as emissions rise, and further away as emissions decrease. An alternative view projects the time remaining to 2.0°C of warming. [1] [2] The clock is updated every year to reflect the latest global CO 2 emissions trend and rate of climate warming. [1]
In 2016, the global average temperature was already 1.1°C above pre-industrial levels. [15] According to the review of the scientific literature conducted by the Intergovernmental Panel on Climate Change (IPCC), carbon dioxide is the most important anthropogenic greenhouse gas by warming contribution.

Global map of greenhouse gas (GHG) emissions, including agriculture and land use change, measured in carbon dioxide-equivalents over a 100-year timescale. [1] Annual GHG emissions by region, including agriculture and land use change, measured in carbon dioxide-equivalents over a 100-year timescale [2] Per capita annual GHG emissions, including agriculture and land use change, measured in ...
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
These numbers show that awareness of global warming was increasing in the United States. [306] A Gallup poll showed that 62% of Americans believe that the effects of global warming were happening in 2017. [307] In 2019, Gallup poll found that one-third of Americans blame unusual winter temperatures on climate change. [308]

A map tool draws direct lines between an area's projected climate in 60 years and the places that are experiencing that climate today. Will global warming turn L.A. into San Bernardino? Map models ...
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [29] [30] [31] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes.
