Sentences with phrase «surface warming»
"Surface warming" refers to the increase in temperature on the Earth's surface, caused primarily by human activities such as burning fossil fuels, deforestation, and industrial processes. This term describes the gradual heating of the land and ocean surfaces, leading to global climate change and various environmental impacts. Full definition

We could also be seeing the end of the much - discussed slowdown in surface warming since 1998, meaning this is just the start of a period of rapid warming.
To begin, they suggest the climate community replace the term «global warming hiatus» with «global surface warming slowdown» to eliminate confusion.
This CO2 rise alone would have caused approximately 0.1 °C surface warming, which is approximately 20 % of the total observed warming during that period.
It is instead a surface water vapor feedback which adds additional surface warming on top of the usual things we talk about.
They also find that increasing emissions lead to increased surface warming and that this warming will last many centuries.
Maximum warming occurs over the surface during winter while less surface warming is found in summer when heat is being used to melt sea ice.

Yes, the oceans are warming but these trends are 10 % to 20 % of the predicted surface warming trend of about 0.2 C per decade.
However, this trend seems unlikely to continue, and we will probably see accelerated surface warming in the coming decades.
If the best mitigation efforts are made and we get lucky with climate sensitivity and carbon - cycle feedbacks, we might succeed in limiting surface warming to 2 - 3 °C.
Unfortunately, there is limited evidence as to whether and to what extent differential air - sea surface warming occurs in the real climate system.
The suspected triggers for accelerated ice discharge on both continents include surface warming and melt runoff, ocean warming, and circulation changes.
