ok.
quick experiment
take some water..boil it...watch the steam come off of it
now, imagine what happens when that steam gets cold...massive snowfall, bitter cold.
during a warming earth, water gets warmer...making more precipitation...aka, steam..go into the atmosphere.
then the earth gets cooler during winter and suddenly, you have a massive snowfall...yes...your right, the climate seems to be destablizing..it goes crazy.
this has and is the outlaying of a warming planet...the weather gets crazy..the summers get a little hotter each year...they last a little longer, then the winters go from blizzards to springtime, back to blizzards, etc.
people should stop thinking like day to day weathermen and start thinking like meteorologists when it comes to the global warming/climate destablization science.

Don't shut up OP. You're on target. Global warming is the precursor to transition to an ice-age or ice-age like event.
I'll put up some links to back this up at some point.
Interstadials. Sudden warm and moist phases occurred at various times during the timespan of the last glacial phase, often taking Greenland and Europe from a full-glacial climate to conditions about as warm as at present. For the time period between 115,000 and 14,000 years ago, 24 of these short lived warm events have so far been recognized from the Greenland ice core data (where they are called 'Dansgaard-Oeschger events'), although many lesser warming events also occurred (Dansgaard et al. 1993). From the speed of the climate changes recorded in the Greenland ice cap (Dansgaard et al. 1989), and by observation of the speed of change in sedimentation conditions on land, it is widely believed that the complete 'jump' in climate occurred over only a few decades. The interstadials lasted for varying spans of time, usually a few centuries to about 2,000 years, before an equally rapid cooling returned conditions to their previous state. Recent study of high-resolution deep sea cores (Bond et al. 1997) suggests that for at least the last 30,000 years, interstadials tended to occur at the warmer points of a background north Atlantic (and global?) temperature cycle which had a periodicity of around 1500 years. Not every warm peak was marked by an interstadial, but when each interstadial did occur it tended to begin at around the peak of this background temperature cycle. The same pattern seems to have dominated the occurrence of Heinrich events (below), which tended to begin at the coldest point of the temperature cycle, and the same basic 1500-year climate cycle has apparently continued into the very different world of the Holocene (below).

In the past, the slowing of the Gulf Stream has been intimately linked with dramatic regional cooling. Just 10,000 years ago, during a climatic cold snap known as the Younger Dryas, the current was severely weakened, causing northern European temperatures to fall by as much as 10 degrees. Ten thousand years before that, at the height of the last ice age, when most of the UK was reduced to a frozen wasteland, the Gulf Stream had just two-thirds of the strength it has now.
The bitter winter afflicting much of the Northern Hemisphere is only the start of a global trend towards cooler weather that is likely to last for 20 or 30 years, say some of the world’s most eminent climate scientists.
Their predictions – based on an analysis of natural cycles in water temperatures in the Pacific and Atlantic oceans – challenge some of the global warming orthodoxy’s most deeply cherished beliefs, such as the claim that the North Pole will be free of ice in summer by 2013. According to the US National Snow and Ice Data Centre in Colorado, Arctic summer sea ice has increased by 409,000 square miles, or 26 per cent, since 2007 – and even the most committed global warming activists do not dispute this.
Not in all my life have i ever seen such cold weather here in Worcester UK.... Not a big deal? It is when all youve ever known is temperatures around 3-6c in the winter for all your life. Something isnt right
We want to compare the sun's brightness now to its brightness during previous minima and ask ourselves, is the sun getting brighter or dimmer?"
Lately, the answer seems to be dimmer. Measurements by a variety of spacecraft indicate a 12-year lessening of the sun's "irradiance" by about 0.02% at visible wavelengths and 6% at EUV wavelengths.... science.nasa.gov...

Lesson from the past: present insolation minimum holds potential for glacial inception
Because the intensities of the 397 ka BP and present insolation minima are very similar, we conclude that under natural boundary conditions the present insolation minimum holds the potential to terminate the Holocene interglacial. Our findings support the Ruddiman hypothesis [Ruddiman, W., 2003. The Anthropogenic Greenhouse Era began thousands of years ago. Climate Change 61, 261–293], which proposes that early anthropogenic greenhouse gas emission prevented the inception of a glacial that would otherwise already have started....
Temperature and precipitation history of the Arctic
Solar energy reached a summer maximum (9% higher than at present) ca 11 ka ago and has been decreasing since then, primarily in response to the precession of the equinoxes. The extra energy elevated early Holocene summer temperatures throughout the Arctic 1-3° C above 20th century averages, enough to completely melt many small glaciers throughout the Arctic,..."
Abrupt Climate Change: Should We Be Worried? - Woods Hole Oceanographic Institution
Most of the studies and debates on potential climate change, along with its ecological and economic impacts, have focused on the ongoing buildup of industrial greenhouse gases in the atmosphere and a gradual increase in global temperatures. This line of thinking, however, fails to consider another potentially disruptive climate scenario. It ignores recent and rapidly advancing evidence that Earth’s climate repeatedly has shifted abruptly and dramatically in the past, and is capable of doing so in the future.
Fossil evidence clearly demonstrates that Earth vs climate can shift gears within a decade.... <
But the concept remains little known and scarcely appreciated in the wider community of scientists, economists, policy makers, and world political and business leaders. Thus, world leaders may be planning for climate scenarios of global warming that are opposite to what might actually occur...
“At the most extreme stage of the last glaciation, most of Canada and much of the northern USA were covered by an ice sheet thousands of metres in thickness. Colder and often drier than present conditions predominated across most of the USA.
The eastern deciduous and conifer forests were replaced by more open conifer woodlands with cooler-climate species of pines and a large component of spruce. The open spruce woodland and parkland extended somewhat further west than present, into what is now the prairie zone.
As a result of aridity and lowering of sea level (which lowered inland water tables), much of Florida was covered by drifting sand dunes. Notably moister than present conditions occurred across much of the south-west, with open conifer woodlands and scrub common in areas that are now semi-desert.
