Crazy talk by NW. Did you actually read the article I posted? I thought not. Slurs are pretty much your stock in trade. |

I just heard about this study last night. I'm sure the deniers have talking points to try to rebut it--but if correct it forecasts a sea level rise of more than a meter by 2100 and a minimum increase of 10 feet already baked in the system from existing CO2 levels. This is certainly supported by accurate measurement of heat stored in the ocean, reported here earlier from Scripps scientists.

OR THIS...
Experts say that solar activity as low as it currently is has not been seen since the mini-ice age that took place between 1645 and 1715 – a period known as the Maunder Munimum where the entire Thames froze over.
A new model has allowed experts to predict solar activity with more accuracy than ever before and it suggests that magnetic activity will fall by 60 per cent between 2030 and 2040.
The model looks at the Sun’s ’11-year heartbeat’ – the period it takes for magnetic activity to fluctuate. This cycle was first discovered some 173 years ago.
However, a mathematician has established a more up-to-date model that can forecast what the solar cycles will look like based upon dynamo effects in two layers of the Sun. |

Golden Dawn, as usual, doesn't give the source for the old denier thread. It can readily be found on many rightish sights, with this up first: https://reportuk.org/2016/10/21/earth-heading-for-another-ice-age-scientists-expect-big-freeze-as-solar-activity-slumps/
Of course we have known about the Maunder Minimum for many decades; it is named for Edward Maunder who reconstructed the European sunspot records. The most significant expression of the phenomenon is the little ice age in Europe, between 1645 and 1720. There are more than one Maunder Minimum cycles--a regular one of 11 years and a much greatrer magnitude one that has a period measured in many decades. Reputable sources--something quite alien to Golden Dawn and the rest of the denier crew--provide details on the nature of the Maunder Minimum, see:
http://www.historicalclimatology.com/blog/what-was-the-maunder-minimum-new-perspectives-on-an-old-question
The article that someone had to have sent Golden Dawn predicts an ice age in 2022. Well, I will live long enough to laugh at him about that claim. Of course the claims of the Maunder Minimum have been discussed in the literature--and debunked. I'll give you just one, then chuckle and go get some exercise:
Quote: | Recent articles in the Danish newspaper Jyllands-Posten (translation available here) and in the Irish Times both ran headlines claiming that another grand solar minimum could potentially trigger an "ice age" or "mini ice age" this century. These articles actually refer to the Little Ice Age (LIA) – a period about 500 to 150 years ago when global surface temperatures were approximately 1°C colder than they are today. This is quite different from an ice age, which are more like 5°C colder than today. The LIA was not actually very cold on a global scale.
So, in order to trigger another LIA, a new grand solar minimum would have to cause about 1°C cooling, plus it would have to offset the continued human-caused global warming of 1 to 5°C by 2100, depending on how our greenhouse gas emissions change over the next century.
In the Jyllands-Posten article, Henrik Svensmark (the main scientist behind the hypothesis that the sun has a significant indirect impact on global climate via galactic cosmic rays) was a bit more measured, suggesting,
"I can imagine that it will become 0.2°C colder. I would be surprised if it became 1–2°C"
So these two articles are suggesting that a grand solar minimum could have a net cooling effect in the ballpark of 1 to 6°C, depending on how human greenhouse gas emissions change over the next century. Is it plausible that a grand solar minimum could make that happen?
The short answer is, 'No.' |

Some people seem to forget that controversy, whether real or manufactured, sells newspapers. |

As does fear, whether real or manufactured.

Americans are more scared of clowns than they are of climate change.
According to a poll conducted by Chapman University, 42 per cent of Americans are afraid of clowns, whereas only 32 per cent are afraid of climate change. |
