The climate is continually changing. If it didn’t something would be very wrong. Some of the national parks exist in great measure due to past changes in climate on a vast scale.
Take for example the following from Wikipedia:
Mesa Verde National Park is a U.S. National Park and UNESCO World Heritage Site located in Montezuma County, Colorado, United States. It is the largest archaeological preserve in the United States.[3] The park was created in 1906 by President Theodore Roosevelt to protect some of the best-preserved cliff dwellings in the world, or as he said, “preserve the works of man”. It is the only cultural National Park set aside by the National Park System.[4] It occupies 81.4 square miles (211 km2) near the Four Corners and features numerous ruins of homes and villages built by the Ancient Pueblo peoples, sometimes called the Anasazi. There are over 4000 archaeological sites and over 600 cliff dwellings of the Pueblo people at the site.
The Anasazi inhabited Mesa Verde between 600 to 1300, though there is evidence they left before the start of the 15th century. They were mainly subsistence farmers, growing crops on nearby mesas. Their primary crop was corn, the major part of their diet. Men were also hunters, which further increased their food supply. The women of the Anasazi are famous for their elegant basket weaving. Anasazi pottery is as famous as their baskets; their artifacts are highly prized. The Anasazi kept no written records.
By the year 750 the people were building mesa-top villages made of adobe. In the late 1190s they began to build the cliff dwellings for which Mesa Verde is famous.
...
By 1300 AD prolonged drought had caused the fragile adaptation to collapse and the Mesa Verde area was abandoned. The surviving Mesa Verde people retreated to the south and east.

As with everything liberal, he who controls the meaning of words or even why we are having the conversation in the first place, controls the outcome of the debate. This has never been more true than in the case of Global Warming, er, now called Climate Change.
I am waiting for some climate scientist to publish a paper on what the optimum climate is for our biosphere. The first question that would naturally flow would be where is our current trend in relation to this finding.
That nobody seems interested in this vital comparison indicates that there climate is being studied for other purposes. Since all the urgent demands that flow from today’s climate science all converge on policy solutions that involve statism, bigger government, higher taxes, less personal liberty, the bigger picture tells me all that I need to know about “climate science”.
I am also curious about how deep the ice got during the last of several periods of glaciation of the northern hemisphere, but that is a question for another time.
A mile of ice over the Obama's residence sounds about right. Alas that missed by about 20k years.
