<span style="font-size:12.0pt">1. NOAA has released the first major update since 2017 to its sea level projections. The regional variations are significant, with the US East Coast, for example, due for much greater rise in the near term than is the West Coast.
If emissions were frozen at current levels (not that they will or could be), the study projects an average of only one foot of additional rise in the last half of the century—the “baked-in rise” that most news stories focus on as if it were a sum projection
rather than an illustration of the benefits of quick climate action. <span style="mso-spacerun:yes">

<span style="font-size:12.0pt">2. The new projections are significantly lower than those of 2017, in part because we now believe that the Antarctic glaciers may be more stable than we did in 2017. The lower projections give our coastal areas in general more
time to plan and prepare. Florida, however, has seen a rise at the previously projected intermediate high level and is still due for an alarming challenge, as the Miami Herald details. (The upper East Coast is in for even more severe rises.)

support Big Ag, gas and oil, plastic water, and others like them would go far to fund their remedies. A proposal to move toward that will be submitted at the COP15 on biodiversity this year.

<span style="font-size:12.0pt">5. The lithium-sulfur battery has been under examination</span>
<span style="font-size:12.0pt">for over a decade but has not lasted long enough to be commercially viable. Now a new application with a rare form of sulfur promises not only to carry three times the charge of a conventional Li-ion battery but to last longer.
Because it avoids using such problematic materials as cobalt, manganese, and nickel, it is also more eco-friendly and surely cheaper. As it carries more charge per unit of weight, it should be possible to greatly lighten autos, giving them correspondingly
increased range. Like 600+ miles. May it be so. <a href="https://cleantechnica.com/2022/02/17/lithium-sulfur-batteries-commercial-viability-improves-with-breakthrough-in-cathode-chemistry/">
