Adaption is always the smartest policy. It's how evolution works, no? Those that can adapt survive. Those that survive pass on their traits to the future and shape those generations.

A stellar engine is a fairly massive undertaking, even for a type-2 civilization. It would be easier (and cheaper) to simply tow the Earth out a ways and call it good.
On the other hand, if we move the sun, we can pick a cooler neighborhood.

So what do you suggest we do about it?
retreating snow cover exposes barren rock near Cape Folger on the Budd Coast on January 11, 2008 in the Australian Antarctic Territory.
The reports are shocking, but not surprising, said Frida Bengtsson, who is leading a expedition to the Antarctic for the environmental group Greenpeace. “We’ve been in the Antarctic for the last month, documenting the dramatic changes this part of the world is undergoing as our planet warms,” she said in an email. “In the last month, we’ve seen penguin colonies sharply declining under the impacts of climate change in this supposedly pristine environment.”
WMO experts will now investigate whether the warm event recorded by Argentine scientists is a weather phenomenon known as foehn. That is a common event in Alpine regions that often involves high winds at altitude and the rapid warming of air as it heads down slopes or peaks, driven by significant air pressure differences
Migration and Vagrancy:
Adelie Penguins are migratory and after breeding do not return to their colonies until the next spring. Little is know about the non-breeding distribution of this species. There are only a few records of Adelie Penguins during the Antarctic winter. Recent work using satellite telemetry indicates that Adelie Penguins from the Ross Sea leave this area in autumn and migrate about 600 km north of the Antarctic continent. Juveniles are suspected to travel even further north than adults. Vagrant birds have been recorded as far north as South Georgia, Falkland Islands, Kerguelen, Macquarie Island, Tasmania, Heard Island, and the South Island of New Zealand.
Migration and Vagrancy:
Little is known about post-breeding dispersal or migration. Adults stay close to the permanent ice for most of their lives. Juveniles equipped with satellite transmitters, however, migrated as far north as the polar front. Vagrants have turned up on the South Shetland Islands, Tierra del Fuego, the Falklands, South Sandwich Islands, Kerguelen Island, Heard Island, and New Zealand.
Migration and Vagrancy:
Chinstrap Penguins leave their breeding colonies during winter, probably migrating north of the pack-ice and stay at sea until the next spring. Non-breeders have been recorded in Adelie Land, Antarctica and stragglers have reached Australia and Tierra del Fuego.
Migration and Vagrancy:
Gentoo Penguin can be found near their colonies all year round unless ice prevents access, as it can in the southern parts of their range. Nevertheless, vagrants have been found as far north as 43°S on the Argentinean coast as well as in Australia and New Zealand.
Migration and Vagrancy:
Due to the extended breeding cycle some birds can be found in the colony at any time of the year. During winter, adults leave their chicks unattended and may travel extensively before returning. Stragglers have reached the Antarctic Peninsula, Mawson, Gough Island, South Africa, southern Australia (including Tasmania), the North and South Islands of New Zealand, as well as New Zealand’s sub-Antarctic islands.
Migration and Vagrancy:
Macaroni Penguins are migratory and found only exceptionally near land during the non-breeding season. Vagrant dark-faced birds are known from South Africa, Antarctica, Campbell Island, and The Snares. Royal Penguins have been recorded, possibly breeding, on Heard, Kerguelen, Crozet Island, and Marion Island amongst dark-faced Macaroni Penguins and stragglers have been observed as far north as North Island, New Zealand.
Migration and Vagrancy:
The non-breeding pelagic range is poorly known. Moulting birds especially have been found in South Africa, Australia and New Zealand. The western subspecies (nominate form) has been recorded as far as the Snares Islands during moult. Vagrants of the Northern Rockhopper have been recorded on the Chatham Islands.

You do know that they've only been keeping temperature records in Antarctica for about 30 years, right? That's not a very long period of time as far as something like reliable climate records are concerned.
