Bjorn Lomborg, a noted critic of global warming research and author of "The Skeptical Environmentalist," has altered his position, recently noting that global warming is "undoubtedly one of the chief concerns facing the world today" and "a challenge humanity must confront". In his newest book, to be released new month, Lomborg details the need to invest in policies that address global warming, which he argues could solve the problem by the end of this century. Lomborg argued that as much as half of the needed funds can be generated by taxes on carbon emissions.
