Global Warming in the First Half of the 21st Century

A reader sent us a surviving Wikipedia entry on global warming.

We have also received a number of submissions about global warming in the first half of the 21st century, but these have tended to be primarily polemical critiques of the cabal of energy companies and USNA governmental officials who for years denied the role of human activity in global warming.

Readers are invited to submit additional potential Holopedia and/or surviving Wikipedia entries on global warming in the second half of the 20th century and the first half of the 21st century. We are looking for an article that will focus exclusively on:
(1) the data that established the reality of global warming
(2) the role of human activity and natural cycles in the rapid increase of global warming in the 20th and 21st centuries
(3) the effects of global warming on climate, dramatic weather events, rising sea levels and island inundations, and other unnatural disasters during this period. We would also welcome a separate, although, balanced analysis of how government authorities, especially in the USNA, responded to the threat of global warming during the first three decades of the 21st century.
