(CNN) -- Global warming has propelled Earth's climate from one of its coldest decades since the last ice age to one of its hottest -- in just one century. A heat spike like this has never happened before, at least not in the last 11,300 years, said climatologist Shaun Marcott, who worked on a new study on global temperatures going back that far. "If any period in time had a sustained temperature change similar to what we have today, we would have certainly seen that in our record," he said. It is a good indicator of just how fast man-made climate change has progressed. A century is a very short period of time for such a spike.
If not for man-made influences, the Earth would be in a very cold phase right now and getting even colder, according the joint study by Oregon State University and Harvard University. Marcott was the lead author of the report on its results. To boot, the range of temperatures from cold to hot produced since the industrial revolution began are about the same as the 11,000 years before it, said Candace Major from the National Science Foundation, "but this change has happened a lot more quickly." Far from natural warming Variations in how the Earth is tilted and its orbit around the sun make for a pattern of planetary warming phases followed by cooling phases across the millennia. The team's research shows the Earth's overall temperature curve dipping down over about the past 4,000 years, but the downward plod comes to an abrupt halt in modern times. "If you were to predict -- based on where we are relative to the position of the sun and how we are tilted -- you would predict that we would be still cooling, but we're not," Marcott said. Instead, the planet is warming up. It hasn't been quite this warm in thousands of years. And it's getting hotter. By 2100, the Earth will be warmer than ever before, Marcott said. If emissions continue as currently predicted until then, global temperatures will rise "well above anything we've ever seen in the last 11,000 years." That could be a rise of 2 to 11.5 degrees Fahrenheit, according to the NSF. http://www.cnn.com/2013/03/08/world/world-climate-change/
So let's break this down - the bottom line is that the earth is in a natural global cooling cycle (like I have been saying for years). Cold is a more predominant threat to mankind than warming. Increased cold will lead to millions of deaths across the globe. Keeping this in mind, if man is having an impact which keeps the planet warm then this effort should be heartily applauded and embraced. Surely global warming is preventing a catastrophic event from being inflicted on man by impending cold. Obviously their prediction that the earth will increase in temperature by 2 to 11.5 degrees by Year 2100 is completely incorrect. The earth has not risen in temperature for the past 17 years. Unfortunately this breaks the claim that man has any impact on global temperature - so sadly man will not be able to prevent the upcoming natural disaster due to global cooling.
The solar sunspot cycle is currently repeating an event that coincided with a little ice age (not that it matters, but how many people here know the sun's mag field flipped a few weeks back? No big deal...it's a regular occurrence...and some say ours may be on the verge...both may influence weather, and thereby climate). Some are arguing that the AGW is bigger than solar and orbit. Maybe. I side on the cooling argument, though I'll be the first to agree man may be contributing to warming...he sure is regarding pollution. I know this much. Where I live in Fl, it's almost noon and it's in the mid 20's. I have a sheet of ice on my driveway that won't be melting until tomorrow. I've lived here for 30 years (with a 2 year exception), and I have never seen so many nights in one season where we've had lows in the teens and twenties. Deeper, colder winters are to be expected in cooling cycles or little ice ages, and they don't take centuries to occur. I have only seen one day (back in the mid 80's) when the high didn't break freezing here, tho I understand there was a similar situation during a 2 year period when I was overseas in either 89 or 90. I remember hearing about significant snow and cold during that time for this part of the south.
You are fucking lying again! WTF is wrong with you?! THE EARTH HAS NOT STOPPED WARMING OR EVEN SLOWED DOWN....YOU ARE SEVERELY FUCKING RETARDED.
For decades we measured warming by taking the world wide average land temp. FC... you crack pot liar. There has been now statistically discernable warming 17 years. If you are unwilling to accept that fact... you should put on a straight jacket. The fact the ocean may still be warming... is what explains why co2 is going up. The change in ocean temps lead the change in CO2.
