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
and scroll down.

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.
 

1. What is a "New Little Ice Age"?

A "New Little Ice Age" refers to a hypothetical period of cooler temperatures and increased glaciation, similar to the Little Ice Age that occurred between the 14th and 19th centuries. It is a controversial concept that some scientists have proposed as a potential future climate scenario.

2. What evidence supports the idea of a "New Little Ice Age"?

There is currently no scientific evidence to support the idea of a "New Little Ice Age." In fact, most climate models and data suggest that global temperatures will continue to rise in the coming decades due to human-caused greenhouse gas emissions. Any temporary cooling periods, such as volcanic eruptions or changes in solar activity, are not significant enough to cause a widespread cooling trend.

3. What would be the potential impacts of a "New Little Ice Age"?

If a "New Little Ice Age" were to occur, it could have significant impacts on agriculture, water availability, and sea levels. However, the exact extent of these impacts is uncertain and would depend on the severity and duration of the cooling period. It is also important to note that the impacts of climate change are already being felt and will continue to worsen regardless of whether a "New Little Ice Age" occurs or not.

4. Is there any way to prevent a "New Little Ice Age" from happening?

As mentioned earlier, there is currently no evidence to suggest that a "New Little Ice Age" will occur. However, the best way to prevent any potential future cooling trend is to address the root cause of climate change - human-caused greenhouse gas emissions. This can be achieved through individual actions, such as reducing our carbon footprint, and collective efforts, such as implementing policies to reduce emissions.

5. What is the consensus among scientists regarding the possibility of a "New Little Ice Age"?

The majority of scientists do not support the idea of a "New Little Ice Age." The Intergovernmental Panel on Climate Change (IPCC) has stated that it is very unlikely that global temperatures will decrease in the coming decades. Additionally, most scientific studies and data support the idea of continued global warming due to human activities. It is always important to critically evaluate information and seek out reliable, evidence-based sources when considering any scientific concept.
