This whole climate thing is getting really hard to keep up with ?

There is no possible way to turn Jupiter or Saturn into a star. They do not have the mass or density required.
like the mini ice age that they predicted in the 70s and/or 80s for the early 2000s that never came?

Is a Mini Ice Age on the Way? Scientists Warn Sun Will "Go to Sleep" in 2030, Could Cause Temperatures to Plummet
(Montage of images of solar activity between August 1991 and September 2001 taken by the Yohkoh Soft X-ray Telescope)
Sources:
A new study claims to have cracked predicting solar cycles - and says that between 2030 and 2040 solar cycles will cancel each other out.
This, they say, will lead to a phenomenon known as the 'Maunder minimum' - which has previously been known as a mini ice age when it hit between 1646 and 1715, even causing London's River Thames to freeze over.
The new model of the Sun's solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun's 11-year heartbeat.
Predictions from the model suggest that solar activity will fall by 60 percent during the 2030s to conditions last seen during the 'mini ice age' that began in 1645, according to the results presented by Prof Valentina Zharkova at the National Astronomy Meeting in Llandudno.

It's going to get a might bit chilly around these parts here in another 15 years. Anyone think "global warming" will prevent the next "Maunder minimum"?
Seems that as of right now, the sun is in a state of high activity, which will cause some high temperatures until this current sun cycle ends around 2020.
I guess we'll soon see how truly accurate (97% accuracy they say) these new models actually are.

Even if you were to somehow manipulate the gravity of Jupiter or Saturn, they don't have the amount of material needed to sustain fusion. It would burn out in no time.
In Europe, examples of very cold winters are 1683-4, 1694-5, and the winter of 1708–9.[13] In such years, River Thames frost fairs were held. However the Thames ceased to freeze in the 19th century largely because the removal
of the "Old" (medieval) London Bridge in 1825 dramatically increased the river's flow into the Pool of London. The original 800–900 feet (240–270 m) bridge stood upon 19 irregularly spaced arches that were set into the river bed on large starlings.
It acted as a weir holding back the slack upstream waters from the tidal brackish, salt water downstream. The construction of Thames Embankment (began 1862) further increased the river's hydrological flow by narrowing the width of waterway through the centre of capital.
"Note that the term "Little Ice Age" applied to the Maunder minimum is something of a misnomer as it implies a period of unremitting cold (and on a global scale), which is not the case. For example, the coldest winter in the Central England Temperature record is
1683-4, but the winter just 2 years later (both in the middle of the Maunder minimum) was the fifth warmest in the whole 350-year CET record. Furthermore, summers during the Maunder minimum were not significantly different to those seen in subsequent years.
The drop in global average temperatures in paleoclimate reconstructions at the start of the Little Ice Age was between about 1560 and 1600, whereas the Maunder minimum began almost 50 years later."

People don't realize that climates change. Antarctica was once green. Now it's not.

Interesting reading. But I don't think the sun will 'go to sleep' . The RAS nor the report from the meeting it quotes says 'little ice age'. It does say it will have the properties of a Maunder Minimum.

If our star is going to cool down there is reason enough to use our failsafe and find a way to light up one of our gas giants.. We beter start working the problem now...

I agree nothing is certain and we certainly shouldn't fear death because thats inescapable but by same token people buy house insurance, fire insurance etc to protect themselves from hardships. If FEMA is spending billions each year on dehydrated foods then perhaps we should consider doing the same, as a type of insurance. We cannot presume FEMA supplies are for the general public, they might be reserves to keep the government and armed services fed.

scientist warn, we cannot predict the future.
2030 you say? luckily the singularity will be happening right around that time to save us maybe.
also I like how antarctica is derailing this thread, cant tell if troll or fail
