Meet the authors of the 'study': Matthew Eckelman (email@example.com) and Mithun Saha of Northeastern University focused their research on how infrastructure in Boston will be affected by the most extreme climate change scenarios. They predict about 60 percent of Boston’s buildings will have some structural deterioration by 2050. Eckelman and Saha published their study results in the journal Urban Climate.
'Over time both carbon dioxide and chloride ions seep into the concrete and corrode the steel bars, called rebar. This corrosion expands the concrete, destabilizing it. Eventually, the damage becomes visible when the facade of a building cracks or chunks of concrete break off.'
CBS News: 'Also interviewed is Marc Morano, a former producer for Rush Limbaugh and staffer for James Inhofe (a major climate change denier in the Senate), who specializes in spin. He proudly tells Kenner about his role in "creating chaos" through on-air debates with actual scientists; and he shows no remorse for the public attacks he launched against NOAA scientist James Hansen, who was among the first to warn of the dangers of CO2 pollution to irreversibly affect the Earth's climate. Morano laughs off having sent or encouraged threats of violence to Hansen, saying he's entertained by reading the threats he receives.'
