SUMMARY

The discussion centers on the implications of an 11-year low in sunspot activity, which has prompted concerns among some scientists about a potential return to a cooling period, reminiscent of the Little Ice Age. The Younger Dryas, a significant cold period occurring approximately 12,900 to 11,560 years ago, is referenced as a historical parallel. The possibility of a new sunspot minimum, termed the "Landscheidt minimum," is projected for 2025-2030, echoing past solar minima like the Maunder and Dalton minima. The conversation highlights the need for environmental protection regardless of climate change outcomes, emphasizing the importance of accurate perceptions of climate realities.

PREREQUISITES
  • Understanding of solar cycles and sunspot activity
  • Knowledge of historical climate events, particularly the Younger Dryas
  • Familiarity with climate change terminology and concepts
  • Awareness of environmental issues related to pollution
NEXT STEPS
  • Research the implications of solar activity on climate patterns

The Younger Dryas occurred at a time when orbital forcing should have continued to drive climate to the present warm state. The unexplained phenomenon has been the topic of much intense scientific debate, as well as other millennial scale events.

Now an 11-year low in Sunspot activity has raised fears among a small number of scientists that rather than getting warmer, the Earth could possibly be about to return to another cooling period. The idea is especially intriguing considering that most of the world is in preparation for global warming. Could we be preparing for the wrong scenario?

Your link won't work here, I'm afraid Wolram. So I have to limit my reaction to the apparent quote.

The Younger Dryas ...

It will probably take another generation to understand the Younger Dryas. A period allegedly of intense cold between about 12,900 or 12,670 and 11,560 years ago. Even the starting period is subject to debate. Some researches doubt the "cold" character, but not when challenged officially.

The most unnoticed thing however is the exceptional agited reaction (or cause) of the oceans in this period, disdaining the usual inertial delay of the ocean. That's the thing to investigate.

Now an 11-year low in Sunspot activity has raised fears among a small number of scientists that rather than getting warmer, the Earth could possibly be about to return to another cooling period.

Investigation has been done to the position of the planets in relation of the solar motion around it's barycentre. If that mechanism is indeed related to the sunspot activity then a new sunspot minimum could be expected around 2025-2030 according to late Theodore Landscheid like the Maunder and Dalton minimum a few centuries ago. Then, if this minimum is related to the lower temperatures of the little ice ages, a new minimum could be forecasted.

So if it happens, it will be termed "Landscheidt minimum". However, we still need to see if it has anything to do with climate. Of course the proof is in the pudding. Just wait and see.

That is strange the page will load but is lacking story. click on science in left hand coulomb

Thanks Wolram, btw coulomb is the unit of electrical charge. But it's in the column.

Let's focus on the closing remarks:

Our commitment to stop polluting our water systems with pesticides and other dangerous chemicals should be as great as ever, with or without climate change considerations. Dismal air quality now poses significant health risks, especially in urban areas.

Couldn't agree more. Absolutely to bad that this isn't the last sentence.

Those who equate their global warming skepticism with an “anything goes” attitude regarding the environment are seriously jeopardizing the health of our planet and their own health along with it.

A general misconception. 'don't care' equals not sceptism. She would be very surprized to see how many sceptics actually care a lot. Especially about having the right picture and doing the right thing.

If we prepare for global warming in ways that help protect the environment—we’ll still be a lot better off—even on the off chance that we end up with a mini Ice Age instead

The biggest mistake. If your perception of reality is wrong you are bound to take the wrong decisions, the results of which are going to cost dearly, biofuel crop for instance. Also, people don't like being fooled. As soon as it is clear that no catastrophic warming is going to happen anytime, there will be lot of important people very unamused.

Well the column was generated electronically.

I think i see some of the strings of the consensus fuzz ball unraveling, i not sure if any of them will know if their predictions are correct until a major event happens, but for sure the are right about pollution.
