Telemetry says there has been no significant snowfall at any site for at least 10 days!
Ullr, have pity upon us!

I'm not sure you where even a sperm in '58!

I seem to remember the '57-'58 season as being a really warm one as well...
Okay, so I looked it up...

I'm thinking it was before '57-'58: 
For much of Earth's history, the world has been ice-free (even at the poles) but these iceless periods have been interrupted by several major glaciation periods (called glacial epochs) and we are in one now. Each glacial epoch consists of multiple advances and retreats of ice fields. These ice fields tend to wax and wane in approximate 100,000, 41,000, and 21,000 year cycles. Each advance of ice is popularly known in the press as an "ice age" but it is important to note that these multiple events are just variations of the same glacial epoch. The retreat of ice during a glacial epoch is called an inter-glacial period and this is our PRESENT DAY CLIMATE system..
The current Plio-Pleistocene Glacial Epoch had it's beginning about 3.2 million years ago and is probably linked to the tectonic construction of the Isthmus of Panama which prevented the circulation of Atlantic and Pacific waters and ultimately triggered a slow sequence of events that eventually led to cooling of the atmosphere and the formation of new ice fields by about 2.5 million years ago.
So far we have had around 15 to 20 individual major advances and subsequent retreats of the ice field in our current glacial epoch. The last major advance of glacial ice peaked about 18,000 years ago and since that time the ice has generally been retreating (albeit with some short term interruptions).
It is worth remembering that our warm present day inter-glacial climate is the exception, not the rule during a glacial epoch. For as much as 90% of the last 2 million years the ice fields on earth have been more extensive than they are today.
On the other hand, our the current glacial epoch and ice on earth and for the most part is also an abnormality. Our present-day Arctic Ocean is about 10-15°C cooler than it was at the time of the dinosaurs for almost all of the time from about 2 to at least 200 million years ago (Ma) the surface temperature exceeded that of today.

So the consequence of Global Warming is the Dinosaurs walk the earth again and compete for turns with the rest of us?

So if I understand you correctly, the dinosaurs probably could not perform turns all year? What if they lived in Colorado?
I wonder what Ullr thinks of this post.
