last five years are the hottest on record, understanding sea level rise in the Eemian, aridification strikes the Colorado River and PG&E, Trump gets a Twitter lecture from teenagers

The New York Times reports on NASA’s announcement this week that 2018 was the 4th hottest year on record. Similar findings were released independently by NOAA and Berkeley Earth, all noting that the 18 warmest years on record have occurred in the past 19 years, and the five hottest years have been the last five. The clear message; global warming is not a future problem… it is here now. An op-ed in the Sacramento Bee encourages Governor Newsom to recognize climate change as a public health emergency.

Those seeking to downplay the problems associated with climate change have often cited greenhouse studies that conclude plants grow faster with more CO2 in the atmosphere, suggesting that plant growth will help mitigate the impact of carbon dioxide emissions. Of course, a greenhouse does not reflect actual conditions in the environment, and a new analysis summarized by the New York Times concludes that as the world warms plants (and soil) will absorb less carbon dioxide. This is mainly due to the impact of higher temperatures and drier conditions…

oceans warming and ice melting faster than previously thought, septic tanks failing in south Florida as seas rise, the future of the Colorado River, more Americans accept human role in climate change

InsideClimate News reports on a new synthesis of several studies (including the corrected version of one I reported on previously) concluding that the ocean is actually heating up faster than previously thought. A more detailed description of the study is available on Carbon Brief in a special article prepared by the study’s authors. This is unfortunately a big deal, as warmer ocean waters are a key driver of extreme storm events, sea level rise and are a major contributor to changing our climate over the long term. Warming oceans also put stress on marine ecosystems (the New York Times notes this is particularly important for coral reefs, which provide food for millions of people – 20% of all corals have died in the last three years). The key reason that the study concludes oceans are warming faster is improving estimates of ocean temperatures during the 20th century. These temperatures were lower than previously estimated, which leads to the conclusion that the oceans are warming faster in response to the intensified greenhouse effect. In addition, because these new estimates of past temperatures agree well with the output of climate models, these projections of future ocean heating can be considered more reliable…
