Guardian article on Arctic methane emissions claiming “a new climate feedback loop may have been triggered” lacks important context
“This article’s claim that methane deposits in the Arctic Ocean are starting to be released, awakening a “sleeping giant”, cannot be supported by the limited observational data. Besides, even if these newly found seeps are increasing, they are located too deep in the ocean to have a significant impact on the concentration of methane in the atmosphere.”
“The article correctly links estimates of current carbon dioxide emissions from land use and land cover change with fairly conservative estimates for potential carbon sequestration embedded in “natural climate solutions” as part of the climate mitigation strategy to avoid 1.5°C warming.
Land-use and land-cover change is responsible for roughly 10-15% of total global carbon dioxide emissions. Forest management, reforestation, and afforestation where appropriate, is part of the climate mitigation portfolio assessed by Integrated Assessment Models used in the IPCC process.”
“The Breitbart article provides a poorly reasoned and misleading view of how climate change has contributed to recent fires in California and the rest of the western USA. The most informative part of the article is the link that it provides to a piece by Southern California Public Radio, which, unlike the Breitbart article, provides an informative and unbiased look at factors contributing to these recent fires.”
Global Warming and fire suppression practices boost wildfires in the US West, as correctly reported in The Atlantic
“The article provides an excellent summary of how rising air temperatures are leading to drier conditions and more fire activity among forests in parts of the western United States. The article is strengthened by including multiple interviews with scientists who have produced seminal studies of fire-climate interactions in this region.”
“The article is accurate in its descriptions of the physical and ecological processes that are behind permafrost changes. It also does a good job of getting across the nature of the work of actual scientists working in the field, what they are doing and why they are doing it.”
