Increased Extreme Heat and Heat Waves

http://www.climatesignals.org/climate-signals/increased-extreme-heat-and-heat-waves Source:   By Climate Signals For Investigation:   Excerpt: One of the strongest findings of climate science is that global warming amplifies the intensity, duration and frequency of extreme heat events. These events occur on multiple time scales, from a single day or week, to months or entire seasons. The more extreme the heatwave, the more likely the event can be attributed to global warming.  Roughly 75% of extreme heat events globally are attributed to climate change. The signal of climate change is particularly reflected in record-breaking heat waves. ...85% of recent record-hot days globally are attributed to climate change....

More Intense Rains in U.S. Midwest Tied to Farm Mechanization

https://eos.org/articles/more-intense-rains-in-u-s-midwest-tied-to-farm-mechanization Source:   By Bas den Hond, Earth & Space News EoS (AGU) For Investigation:   10.3 Excerpt: “Rain follows the plow,” or so the pioneers who started farms in the drylands of the American West were told. The 19th-century notion that cultivation will always lead to a beneficial change in the climate turned out to be false. But researchers have previously found that climate does respond to what people do on the ground, like when monsoon patterns have been altered by deforestation. Now a new study has investigated the climate effects of a century-long conversion in the United States, from farmers using animals to do almost all of the plowing and other heavy farmwork to using only machines. An increase in heavy rainfall events in the 20th century in the American Midwest appears to be closely tied to that switch from horsepower to mechanized agriculture, according to Taleena Sines of the Int...

Climate Change’s Pulse Is in Central America and the Caribbean

https://eos.org/opinions/climate-changes-pulse-is-in-central-america-and-the-caribbean Source:   By J. E. González, M. Georgescu, M. C. Lemos, N. Hosannah, and D. Niyogi, Earth & Space News (EOS; AGU) For Investigation:   10.3 Excerpt: Nations that border the Gulf of Mexico and Caribbean Sea are ideally placed for tracking the effects of global climate change and testing innovative ways to adapt to future changes. ...The global trend of increasing sea surface temperatures, for example, may work with or against natural modes of climate variability in the region, highlighting the physical system’s complexity and nonlinear nature. Hand in hand with these physical changes are the hazards they pose to people. More than 120 million people live in the area. Despite steady, albeit inequitable, economic growth during recent decades, the region has become increasingly exposed to climate-related pressures that threaten its social and economic well-being. The region’s extensive c...

As Rising Seas Erode Shorelines, Tasmania Shows What Can Be Lost

https://www.nytimes.com/2017/04/26/climate/tasmania-global-warming-shoreline-erosion.html Source:   By Justin Gillis, The New York Times For Investigation:   10.3 Excerpt: ISLE OF THE DEAD, Tasmania — Maybe the hardened convicts who carved the 19th-century gravestones dotting this tiny island were barely literate, or perhaps one of them just had a wicked sense of humor. The schoolmaster Benjamin Horne went to his repose in 1843 with this sentence chiseled above his head: “Sincerely regretted by all who knew him.” ...The very island on which he lies is being chewed away by the sea. The roots of trees that have stood for decades now dangle perilously over a fast-eroding shore. A few miles away, a seaside coal mine once worked by the convicts is under similar assault by the waves. ...In country after country, managers of national parks and other historic sites are realizing that climate change, with its coastal flooding and erosion, rising temperatures and more intense rains...

We Just Breached the 410 PPM Threshold for CO2

https://www.scientificamerican.com/article/we-just-breached-the-410-ppm-threshold-for-co2/ Source:   By Brian Kahn, Scientific American For Investigation:   10.3 Excerpt: The world just passed another round-numbered climate milestone. Scientists predicted it would happen this year and lo and behold, it has. On Tuesday, the Mauna Loa Observatory recorded its first-ever carbon dioxide reading in excess of 410 parts per million (it was 410.28 ppm in case you want the full deal). Carbon dioxide hasn’t reached that height in millions of years. It’s a new atmosphere that humanity will have to contend with, one that’s trapping more heat and causing the climate to change at a quickening rate....
