Global warming, the phenomenon of rising average air temperatures near Earth’s surface over the past 100 to 200 years. Although Earth’s climate has been evolving since the dawn of geologic time, human activities since the Industrial Revolution have a g
Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. They write new content and verify and edit content received from contributors. ...
A warmer planet doesn’t just raise temperatures. From wildfires to flooding to coral bleaching, here are some real-world implications.
A primary goal of the PAGES2k project is to understand climate dynamics over the entire Common Era. Records of this duration are most commonly accessible from sedimentary sequences that lack annual resolution; a minimum length of 500 years for these records serves as a coarse initial screen. For...
As regular meteorological observations in most parts of China started only in the 1950s,it is necessary to reconstruct regional temperature series from high-resolution temperature proxies.Recently,scientists from the Institute of Geographic Sciences and Natural Resources Research,Chinese Academy of Sciences...
temperature records have typically focused on specific time horizons (mostly 6000 years ago), and are based nearly entirely on pollen assemblages from terrestrial archives1,2,3,4, or are dominated by sea-surface temperatures5near continental margins. Few global datasets have been compiled based on ...

(Nagai et al.2005). The preconditioning, which involves the magnetic field configuration and the plasma sheet parameters, such as temperature, density, and ion composition, results not only from the solar wind history but also from coupling with the ionosphere. The pressure distribution in the ...
Undoubtedly, people have always been aware of climatic variation at the relatively short timescales of seasons, years, and decades. Biblical scripture and other early documents refer todroughts,floods, periods of severe cold, and other climatic events. Nevertheless, a full appreciation of the nature...
126. For example, decadal-scale trait evolution related to soil accretion in the dominant sedgeSchoenoplectus americanusover the past 100 years has decreased the resilience of North American tidal marshes to SLR by making root growth shallower and lowering sediment accretion125. In contrast to ...
