The deep web, [1] invisible web, [2] or hidden web [3] are parts of the World Wide Web whose contents are not indexed by standard web search-engine programs. [4] This is in contrast to the " surface web ", which is accessible to anyone using the Internet. [ 5 ]
The term dark web first emerged in 2009; however, it is unknown when the actual dark web first emerged. [11] Many internet users only use the surface web, data that can be accessed by a typical web browser.

Current climate plans still put the world on track for around 2.6C to 2.8C of warming by 2100, according to the UN. This could drop to 1.9C if all net zero pledges were achieved, but this would ...
The World Wide Web is one of the most popular distributed services on the Internet, and the surface web is composed of the web pages and databases that are indexed by traditional search engines. "Clearnet" can be seen as the opposite of the term " darknet ", which typically describes the services built on Tor or other anonymity networks, the ...
The technology behind the World Wide Web, the Hypertext Transfer Protocol (HTTP), does not actually make any distinction between "deep" links and any other links—all links are functionally equal. This is intentional; one of the design purposes of the Web is to allow authors to link to any published document on another site.
Reconstructions of global temperature of the past 2000 years, using composite of different proxy methods. In the study of past climates ("paleoclimatology"), climate proxies are preserved physical characteristics of the past that stand in for direct meteorological measurements [1] and enable scientists to reconstruct the climatic conditions over a longer fraction of the Earth's history.
The difference between climate and weather is usefully summarized by the popular phrase "Climate is what you expect, weather is what you get." [ 16 ] Over historical time spans, there are a number of nearly constant variables that determine climate, including latitude , altitude, proportion of land to water, and proximity to oceans and mountains.
