Guardian coverage of essay on potential of future "hothouse" climate is generally accurate, but misstates some details

“The article reasonably summarizes a new study published in PNAS, which describes the potential of tipping elements to enhance climate warming and the potential for the Earth to transition into a hot-house climate state. The article is careful to point out uncertainties and thus avoids being sensational. However, there are many small errors scattered throughout the article.”

Washington Post accurately covers permafrost study, albeit under a somewhat sensational headline

The article accurately described a study indicating that more of the carbon released from thawing permafrost will be released as methane and provided context on its overall implications by quoting comments from two other researchers. The article’s headline, however, may mislead readers through the use of the sensational phrase “the Arctic’s carbon bomb”, which calls to mind a catastrophic, explosive release of greenhouse gas.

Daily Wire article misunderstands study on carbon budget (along with Fox News, The Telegraph, The Daily Mail, Breitbart…)

“The article selectively quotes from interviews and scientific papers to create the false perception that climate models significantly overestimate the rate of warming. The article also falsely implies that the cited paper is about the so called “hiatus” while the paper is actually about the carbon budget for the 1.5 ºC target.”
