2. Islandic Eruption Risk.  Icelandic officials warned of an imminent volcanic eruption following tens of thousands of earthquakes since late October, including over 2,000 yesterday. Thousands of people have been evacuated from the coastal town of Grindavík on the country’s southwest Reykjanes peninsula, where many of the earthquakes have occurred.

Impact on global climate with every eruption.

The most significant climate impacts from volcanic injections into the stratosphere come from the conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. The aerosols increase the reflection of radiation from the Sun back into space, cooling the Earth’s lower atmosphere or troposphere. Volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming.t want to expect .

5.  Your Eyesight. Humans are born with with two types of photoreceptors in their eyes: rods and cones.  In the day time  we utilize cones – the structures that allows us to see color.  With the onset of night, however, we shift  to a mix of cones and rods.  In very low light, we rely entirely on rods, which is why in the darkness, everything appears black and white.

As you age, you begin to loses rod receptors before you lose cone receptors. So while your vision during the day may appear just fine, your night vision becomes less accurate. Source: Dr. Cynthia Owsley, Chair of Opthhalmology, University of Alabama, Birmingham

6. Historic Claims Put A Few California Farming Families First In Line For Colorado River Water  Posted Nov 11, 2023, 8:58 am Janet Wilson & Nat Lash  The Desert Sun 

Western agriculture, a major part of the region’s economy and a key contributor to the country’s food supply, consumes more  Colorado River water than any other user.

All that land in the blazing-hot southeastern corner of California came with a huge bonanza: water from the Colorado River. In 2022, the present-day Elmores consumed an estimated 22.5 billion gallons, according to a Desert Sun and ProPublica analysis of satellite data combined with business and agricultural records. That’s almost as much as the entire city of Scottsdale, Arizona, is allotted.

That puts the Elmores in exclusive company. They are one of 20 extended families who receive fully one-seventh of the river’s flow through its lower half — a whopping 1,186,200 acre-feet, or about 386.5 billion gallons, the analysis showed.

The Colorado River system, which supplies 35 million people in seven U.S. states and Mexico, nearly collapsed last year. Even after a wet winter, it is dwindling due to overuse and climate change. But no matter how low its reservoirs sink, the historic claims of these families and all of Imperial County place them first in line — ahead of every state and major city — for whatever water remains.

How a handful of families and a rural irrigation district came to control so much of the West’s most valuable river is a story of geography and good timing, intermarrying and shrewd strategy, and a rich but sometimes ugly past when racist laws and wartime policies excluded farmers of color. Together, they winnowed the greatest access to these 20 clans, who today use more of the river than all of Wyoming, New Mexico or Nevada. A vast, laser-leveled green quilt of crops covers this naturally bone-dry valley, all of it grown with Colorado River water.

The water is held “in trust” by the Imperial Irrigation District and two smaller agencies, meaning they are legally required to deliver the water to any county landowner for use on their property.

But many farmers here see the river water as virtually their private property, though nearly all acknowledge it can’t be sold apart from their land.

7. Funding Opportunity: WaterSMART Aquatic Ecosystem Restoration Program.

This grant is for Local governments, Tribal entities, and other partner organizations to study,  design, and construct restoration projects that will enhance the health of fisheries, wildlife, and aquatic habitat. Grant funds range from $500,000 to $2 million.

Completed applications for the Aquatic Ecosystem Restoration Program are due Thursday, January 24th, 2024. To find out more visit BOR’s website: Aquatic Ecosystem Restoration Program | Bureau of Reclamation (usbr.gov).  

8.  EPA Wetland Program Development Grants (WPDGs). The goals of EPA’s wetland program include increasing the quantity and quality of wetlands in the U.S. by conserving and restoring wetland acreage and improving wetland conditions. In addition to developing and/or refining wetland protection and management programs, EPA seeks to build wetlands programs to incorporate climate change and environmental justice considerations. The goal of this grant program is to develop the capacity of state, tribal, or local governments to increase the quantity and quality of wetlands in the US by conserving and restoring wetland acreage and improving wetland conditions.

All applications must be submitted prior to November 20, 2023 at 8:59 PM PT. Grant awardees will receive funding by March 22, 2024. For more information on the WPDGs, visit the EPA website.
