Publicity has surrounded claims of a global warming hiatus during the period 1998–2013. The exceptionally warm El Niño year of 1998 was an outlier from the continuing temperature trend, and so subsequent annual temperatures gave the appearance of a hiatus: by January 2006, it appeared to some that global warming had stopped or paused.

In a 2024 survey, 76.3% of responding IPCC lead authors and review editors projected at least 2.5 °C of global warming by 2100; only 5.79% forecast warming of 1.5 °C or less. [ 98 ] January: the World Economic Forum projected that, by 2050, directly and indirectly, climate change will cause 14.5 million deaths and $12.5 trillion in economic ...
The runoff from the land flows into streams and rivers and discharges into the ocean, which completes the global cycle. [5] The water cycle is a key part of Earth's energy cycle through the evaporative cooling at the surface which provides latent heat to the atmosphere, as atmospheric systems play a primary role in moving heat upward.

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. [28]
Ward and Brownlee predict that there will be two variations of the future warming feedback: the "moist greenhouse" in which water vapor dominates the troposphere and starts to accumulate in the stratosphere and the "runaway greenhouse" in which water vapor becomes a dominant component of the atmosphere such that the Earth starts to undergo ...
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.
Earth last year shattered global annual heat records, flirted with the world’s agreed-upon warming threshold and showed more signs of a feverish planet, the European climate agency said Tuesday.
The global ocean is Earth's largest thermal reservoir that functions to regulate the planet's climate; acting as both a sink and a source of energy. [3] The ocean's thermal inertia delays some global warming for decades or centuries. It is accounted for in global climate models, and has been confirmed via measurements of ocean heat content.
