DEAR APOCALYPTIC WARMUNISTS:
Here's a simple, rational, fact based lesson in climate science for your education: This good, great, fruitful Earth (that's getting greener from the increase of CO2) is in an INTERGLACIAL EPOCH: a period between two ICE AGES of global warming deglaciation where glaciers and ice sheets normally melt and sea levels rise causing some flooding in coastal areas worldwide. But don't you worry your little, hysterical doomsday heads off. Kevin Costner's Waterworld is not around the bend. No need to build arks to save humanity and animals just yet. Depending on the Sun (not anything man does) it could be centuries before Manhattan becomes a floating city like Venice with eco-friendly gondolas instead of gas guzzling cabs riding down 5th Avenue picking up fares. But by then (if such great flooding there be) millions would have fled inland to safety.
But be warned! In 10,000 years or more monster glaciers will return to Manhattan with a vengeance. Polar bears and penguins will overrun the frozen island as planet Earth (cooled by a drop in solar activity) once again enters the BIG CHILL: a long, dark, cold period of brutal, frigid, bone chilling temperatures causing global crop failures and mass starvation - all the horrors predicted in the 1970s during the ice age scare.
Over a period of thousands of years the ice grew covering New England, New York City and all of North America. Then about 18,000 years ago the massive glaciers began to recede and have been shrinking ever since due mainly to increased solar activity causing natural deglaciation.
So my dear, good, world saving warmunists enjoy the warmer weather, it won't last forever. And when it's gone our freezing, starving, sicker, short-lived descendants will look back on us with envy as a golden age of CLIMATE HEAVEN - praying to God, Gaia or whomever for global warming, melting ice and rising seas again.
DISQUS DEBATE ON MEDIEVAL WARMING
Well, I'm a Ph.D. scientist and although climate science isn't my field I do regularly pursue the scientific journals for general news and I haven't seen any news announcing that MWP has been shown to be a global phenomenon - and I'm pretty sure that I would have seen the news story if it existed because that would be pretty big news.
We'll then Mr. Ph'd you'll have to study the papers I referenced and draw your own conclusions. And while you're at it take a look at this huge scientific compilation of mostly MWP reconstructions (in the hundreds) done all over the world, and put in the form of a Google map. The red balloons are where significant warming was found.
I looked at a couple and see no claims of their disputing the fact that MWP was a local phenomenon. For example, there is nothing in the Farmer, et., al. 2005 abstract which suggests that MWP was global. This map has all the appearance of being the work of someone who scattered data points all over the globe based on the regional area covered by a particular paper but who never actually read the papers nor their abstracts to see if they supported his or her point.
Guess not everyone with Ph'ds are good at connecting simple dots. Connect all the data points (red balloons) and what you get is a global phenomenon - north to south (pole to pole), east to west - of significant warming lasting centuries.
