LESS SOLAR RADIATION WILL
NOT OFFSET GLOBAL WARMING

The sun cycles through periods of sunspot inactivity and activity. Each solar cycle lasts around 10 to 12 years. Sunspot activity is greatly enhanced during the several years around each cycle’s peak. The magnetic activity that accompanies the active part of the sunspot cycle can produce changes in the Earth's upper atmosphere via solar wind and extreme ultraviolet (EUV). EUV is highly energetic and is absorbed in the upper atmosphere, which not only heats it but also ionizes it, creating the ionosphere.

Global temperatures tend to be about .4 Fahrenheit warmer during a solar maximum and inversely .4 Fahrenheit cooler during the solar minimum. That is less than ½ of a degree Fahrenheit (¼ degree Centigrade).

It is not enough to counterbalance global warming. The global temperature has risen 1.9 F since the 1880 pre-industrial time frame. Additionally, there is yet another 2 degrees “baked into” the atmosphere due to “committed warming” from the CO2 that is currently being put into the atmosphere.

Category Six has a detailed article explaining the solar cycle…

The Weirdly Quiet Sun May Get Even Quieter (and BTW, Earth Is Still Warming)
Category Six 2-28-19

After the most tepid solar cycle in at least a century, several top forecasters are now predicting an even more lackluster cycle in the 2020s. The sun’s prolonged calmness is fascinating as well as mysterious, but here’s something to keep in mind: even if the sun goes into a multi-decade “grand minimum”, any climate effects are likely to be swamped by human-produced climate change.

Figure 5. Sunspot observations over the past 400 years clearly show the Maunder and Dalton minimums. The Gleissberg cycle is reflected in the Dalton minimum, around 1800, as well as the cluster of quiet solar cycles around 1900 (not labeled). Global temperatures have been increasing since the 1980s even though solar activity, as reflected in sunspot activity, has been on the decrease.

The planet was indeed chilly during the Maunder minimum, with surface temperatures in the Northern Hemisphere about 0.9°F (0.5°C) below their 1961-1990 average. However, the drop in solar input is unlikely to have been the prime cause of the cooling, since the most prolonged cold period of the Little Ice Age (from 1570 to 1750) got under way more than 70 years before the Maunder minimum. Sun-blocking volcanic eruptions are believed to be one of the main drivers of the Little Ice Age.

Indonesia Reduces Deforestation, Norway to Pay Up
World Resource Institute 2-21-19

Indonesia was one of the few tropical nations to reduce its deforestation rates in 2017, and it’s paying off. Norway announced on February 16 that it will provide the first results-based payment to Indonesia as part of a REDD+ agreement the two nations established in 2010.

Adults failed to take climate action. Meet the young activists stepping up
The Guardian 3-4-19

I feel like young people have always played the role of moral clarity and being willing to be idealists about what the world should be like. I see my generation as picking up the baton from young people in the 1960s and in the civil rights movement who engaged in similar efforts. We totally see our struggle as rooted in the past activism of young people.

… “I know that the students want many things to go faster, such as the exit from coal,” Merkel said. “But as head of government, I must point out that we have to take a lot of things into consideration: We have to reconcile jobs and economic health with the goals of climate protection.”

New satellite-based maps of mangrove heights
NASA 2-29-19

Mangroves are among the planet’s best carbon scrubbers, moving far more than their fair share of carbon dioxide from the atmosphere into long-term storage. … Thriving in brackish water that kills other plants, mangroves drop tons of leaves and branches—more than 9 metric tons per hectare (4 tons per acre) per year. The litter decomposes very slowly because the forests flood regularly at high tide. This translates into a lot of carbon taken out of the atmosphere and stored as peat in mangrove soils. … These useful trees are being squeezed between rising seas and coastal development around the world, and scientists are working to assess what that means to the carbon cycle.

Ruined crops, salty soil: How rising seas are poisoning North Carolina’s farmland
Faster Than Expected 3-1-19

Or maybe the problem goes even deeper. Scientists are increasingly concerned that rising sea levels are shifting the “zone of transition” — the underground gradient where fresh groundwater meets salty seawater. This issue may be compounded by the slow sinking of North Carolina’s coastal plain since the end of the last ice age about 12,000 years ago.

Reduced salinity of seawater wreaks havoc on coral chemistry

This is bad news for important ocean ecosystems from kelp forests to coral reefs.

CLIMATE STUDIES

Good article…

Fire below, ice above: volcanoes, glaciers and sea level rise
NASA 3-5-19

The heat welling up from Earth’s interior beneath ice sheets and glaciers has nothing to do with the relatively rapid change in climate over recent decades, driven mainly by human emissions of greenhouse gases that warm the atmosphere. Heat sources from the deep Earth can remain steady for 50, 90 or 100 million years; human-driven climate change is occurring over mere decades and centuries.

Thousands of tiny quakes shake Antarctic ice at night
Science Daily 3-4-19

Scientists placed seismometers on the McMurdo Ice Shelf and recorded hundreds of thousands of tiny 'ice quakes' that appear to be caused by pools of partially melted ice expanding and freezing at night. The phenomenon may be able to help scientists track glacier melting -- and to help explain the breakup of large ice shelves.

Carbon rise could cause cloud tipping point
Climate News Network 2-27-19

If carbon dioxide concentrations in the atmosphere become high enough, the clouds that shade and cool some of the tropical and subtropical oceans could become unstable and disperse. More radiation would slam into the ocean and the coasts, and surface temperatures could soar as high as 8°C above the levels for most of human history.

Global Warnings

Paul Beckwith: "I declare a global climate change emergency to claw back up the rock face to attempt to regain system stability, or face an untenable calamity of biblical proportions."

Kevin Hester: "There is no past analogue for the rapidity of what we are baring witness to. There has been a flood of articles ... 2C is no longer attainable and that we are heading for dangerous climate change"

Guy McPherson: "The recent and near-future rises in temperature are occurring and will occur at least an order of magnitude faster than the worst of all prior Mass Extinctions. Habitat for human animals is disappearing throughout the world, and abrupt climate change has barely begun."
