1. NOAA reports that high tide flooding is likely to double in 2019 on a 2000 base, with the East Coast seeing particularly frequent floods. The Northeast is projected to see a 140% increase, and the Southeast a 190% increase. Continuing El Nino conditions are a factor, along with sea level rise.  https://www.noaa.gov/media-release/us-ties-record-for-number-of-high-tide-flooding-days-in-2018

2. John Cook, Katharine Hayhoe, and others share about five minutes of keys to effective communication on climate. https://climatecrocks.com/2019/07/23/can-you-spot-science-denial-take-the-quiz/

John Cook of George Mason University is author of the famous “97 Percent of Scientists Agree on Climate Change” study. He’s been studying and explaining the most common techniques…

3. Forty years ago, a group of scientists gathered at the Woods Hole Oceanographic Institute as the “Ad Hoc Group on Carbon Dioxide and the Atmosphere.” In the Charney Report they accurately forecast the likely effects of the buildup of CO2 on the climate, along with the uncertainties. (The greenhouse effect had been known since the early 1800s, and the importance of CO2 since the middle of that century.)  https://phys.org/news/2019-07-charney-years-scientists-accurately-climate.html

This month the world has been celebrating the 50th anniversary of Neil Armstrong setting foot on the Moon. But this week sees another scientific anniversary, perhaps just as important for the future of civilisation.

4. A UN special climate summit in New York on September 23 will be followed by COP 25 in Santiago, Chile. COP 26 convenes in England at the end of 2020. That is likely to be our deadline for action to hold heating to 1.5C, giving us about a 2 in 3 chance of avoiding catastrophic climate disruption. https://www.bbc.com/news/science-environment-48964736

5. Greta Thunberg admonishes the French parliament to attend to the schedule for action implied by the carbon budget. (As a recent news list recorded and the BBC story above reflects, the budget is tighter than the IPCC had supposed.) https://climatecrocks.com/2019/07/24/greta-thunberg-to-french-parliament-perhaps-you-are-not-mature-enough/

“It’s almost like you don’t even know these numbers exist. As if you haven’t even read the latest IPCC report, on which much of the future of our civilisation is depending ...

6. As the earth heats we become ever more likely to experience hurricanes followed by heat waves. With electricity supply usually disrupted and air conditioning unavailable, populations will be especially exposed to health risks after the storms. http://www.anthropocenemagazine.org/2019/07/get-ready-for-the-one-two-punch-of-hurricanes-and-heat-waves/?utm_source=Anthropocene&utm_campaign=460c82b9a8-Anthropocene+science+to+AM&utm_medium=email&utm_term=0_ececcea89a-460c82b9a8-294268545

Most discussion of climate change and extreme weather focuses on how existing weather hazards such as heat waves, floods, and droughts are likely to become more frequent and intense.
