This is because ocean warming increases near-surface stratification, subsurface layer is still in equilibrium with the colder climate. This causes the surface amplification to be stronger than older models predicted. [33] An instrument carried by the SAC-D satellite Aquarius, launched in June 2011, measured global sea surface salinity. [34] [35]
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 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]
The world temporarily surpassed the 2C warming line, going beyond the upper warming limit of the global Paris Agreement. As we hit these milestones, we have also learned that a warming planet does ...
Some groundwater finds openings in the land surface and emerges as freshwater springs. In river valleys and floodplains, there is often continuous water exchange between surface water and ground water in the hyporheic zone. Over time, the water returns to the ocean, to continue the water cycle. The ocean plays a key role in the water cycle.
The first chapter describes the expected effects of climate change with one degree Celsius (1 °C) increase in average global temperature since pre-industrial times.. The second chapter describes the effects of two degrees average temperature and so forth until Chapter 6 which shows the expected effects of an increase of six Celsius degrees (6 °C) average global temperature.
Water condenses on the surface, leading to carbon dioxide dissolving and chemically binding to minerals. This reduced the greenhouse effect, lowering the temperature and causing more water to condense. The result was lower temperatures, with water being frozen as subsurface permafrost, leaving only a thin atmosphere.
The book describes strategies for achieving net zero greenhouse gas emissions by 2050, and emphasizes that many efforts to reduce emissions are actually counter-productive. For example, one can reduce CO 2 emissions in 2030 by replacing a coal-fired electrical power plant with a new natural gas power plant (since coal combustion emits twice as ...
