What difference does it make. We are still nowhere near the pleasant weather enjoyed in medieval times when they grew grapes in England.

There is also a growing number of small scale producers of grapes and wine in southern Quebec and Nova Scotia. The two largest wine-producing regions in Canada are the Okanagan Valley of British Columbia and the Niagara Peninsula of Ontario.

Whew! Thought the globaL cooling had us for a bit.
Why can't one purchase a good Catawba any more..............:roll:
14,000 years ago Holocene warming Slow warming from the last ice age; large ice melt
10,000 - 8500 BC Younger-Dryas Rapid cooling, prolonged cold period, then Rapid warming
5000 - 3000 BC Climatic optimum Warm conditions; temperatures were perhaps 1 to 2 degrees Celsius warmer than they are today. Great ancient civilizations began and flourished.
3000 - 2000 BC * Cooling trend; drops in sea level and the emergence of many islands.
2000 - 1500 BC * Short warming trend
1500 - 750 BC * Colder temperatures and renewed ice growth, sea level drop of between 2 to 3 meters below present day levels.
750 BC - 150 BC * Slight warming not as warm as the Climatic Optimum.
150 BC - 900 AD * Cooling trend; Nile River (829 AD) and Black Sea (800-801 AD) froze
1100 - 1300 AD Little Climatic Optimum or Medieval Optimum Warm; warmest climate since the Climatic Optimum, Vikings established settlements on Greenland and Iceland.
1300 - 1550 AD * Cool and more extreme weather; abandonment of settlements in the Southwest United States,
1550 to 1850 AD Little Ice Age Coldest temperatures since the beginning of the Holocene. Populations die from crop failure and famine in Europe.

please provide consensus scientific evidence that the "Medieval Warming Period" was global in affect. In any case, what is your point in comparing Medieval times England's grape growing to today's relatively recent warming?
it's clear you don't understand temperature analysis. The ocean component of that graph is sea-surface temperature (SST)... it has nothing to do with ocean heat content and the deeper layers/depth of the ocean. In any case, I've added the trend line in for you below... of course, trending on a relatively short period like 14 years isn't an appropriate analysis period for climate trending:
what's being tracked is warming over that, as you chose, 130 year period. Attribution causal ties for warming is analyzed and assigned by scientists, whether the period is 50 years, 130 years, 800,000 years... or your 4 billion year reference.
Consensus? That dead horse is being flogged again? 99% of the 33% who believe in AGW falls short by 67% to be a consensus.
for anyone taking exception to my use of the word consensus in regards the earlier reference to the Medieval Warming Period (MWP) being global, you could provide scientifically accepted publication that the MWP was global... you could provide citation to confirm the temperatures of the MWP were warmer than today... you could provide what significance you presume to draw when comparing the MWP (local, regional, global... whatever) to today's relatively recent warming?
for those that actually know what the consensus is and how its been properly presented, conveyed and interpreted, it is:

Nobody from Kijiji needs drywall done today or you figured it was a good day to sit on your ***, suck the glass cock while ranting about sh-t you have no clue about thanks to dropping out in grade 9?

That looks like the US, not global.
There's no doubt the US is cooling right now--it's winter.
It's winter.
There's some evidencer that teh MWP was global in effect. It is unlikely that the MWP was as warm as the last few years, but there is a low probability chance that it may have been warmer. Data are scarce, so uncertainties are high.
Winter is coming.
It's going to be up and down for the next couple Ka as the Holocene stabilizes before heading back into the next glaciation.
Ice on the pond this morning. Some of it is still there. When was global warming supposed to start again?
