You saw the corrected data. It shows a dramatic rise. Let’s take another look…
Showing a graph for over the past 130 years does not disprove my point.
But the section of the graph, showing a sharp rise in temperatures over the last ten years does. Notice the red line, the average temperature, is sharply up. Notice also that the period from 2000 to 2005 had five of the six top record average temperatures.
The trend in the last ten years has been downward. Even NASA’s findings agreed on that.
Read the graph again. They lied to you about that. The data says it’s getting warmer rapidly. BTW, the current denier position is that it’s getting warmer, but the sun is to blame.
**Following the latest projections by the UN’s Intergovernmental Panel on Climate Change (IPCC), new research shows that models in the report underestimate some changes that are already under way. Sea ice is melting and sea level is rising faster than models had predicted, and one brake on warming, the uptake of CO2 by oceans, appears not to be working as well as scientists had thought.
Results published in Geophysical Research Letters in May show that ice-free summers could be even more likely this century than estimated in February’s IPCC report. Julienne Stroeve of the National Snow and Ice Data Center led a group that analyzed nearly 60 years of sea ice records from satellites, ships, and airplanes, concluding that ice has disappeared at an average rate of 7.8% per decade since 1953, compared with 2.5% per decade in computer simulations.
See the graph. Note that the difference between “corrupt” and corrected data is indistinguishable at normal resolution.
When sea ice melts, it adds nothing to the sea level rise…
Ice caps aren’t sea ice; they are on land, and yes, when they melt, the sea rises. Another thing they lied to you about.
And Anarctica isn’t yet a major cause of sea level change, since most of the melt there (unlike Greenland) is on ice shelves that are essentially floating. In fact, because of more humidity caused by melt, one expects more snow to fall in the interior and somewhat offset the melting from glaciers. Up until very recently, that has been the case…
In all, snowfall and ice loss in East Antarctica have about equaled out over the past 10 years, leaving that part of the continent unchanged in terms of total ice. But in West Antarctica, the ice loss has increased by 59 percent over the past decade to about 132 billion metric tons a year, while the yearly loss along the peninsula has increased by 140 percent to 60 billion metric tons. Because the ice being lost is generally near the bottom of glaciers, the glacier moves faster into the water and thins further, as a result. Rignot said there has been evidence of ice loss going back as far as 40 years.
Let’s take a look at that data he got…
The first plot shows the 5yr average temperature for the lower 48:- red line is for stations with CRN=1 and CRN=2 (CRN12, the good stations).- green line is for stations with CRN=5 (CRN5, the bad stations).- blue line was downloaded from GISS on Sept 14, 2007 (GISS).
The agreement between the results is very good for all sets.
Surprise. They lied to you yet again.
How un-biased of you…
Data is always better than opinion. At any rate, your guy’s own numbers confirm the warming trend. I’d be open his reasoning that the close agreement between data sets isn’t evidence for warming. Tell us about it.
Let’s take a look…
After Antarctica, Greenland’s ice cap contains the second largest mass of frozen freshwater in the world. This new research indicates enough ice loss to cause a measurable rise in sea levels. Quantified conservatively, the study indicates a net loss of roughly 51 cubic kilometers of ice per year from the entirety of the Greenland ice sheet.
Glaciers in Alaska and neighboring Canada, with a combined area of approximately 90,000 square kilometers (roughly 35,000 square miles), and accounting for about 13 percent of mountain glaciers on Earth, have thinned substantially. Over the last 40 years, thinning has been on the order of 50 to 100 meters (several hundred feet) at lower elevations of glacier occurrence, and about 18 meters (60 feet) at higher elevations.
West Antarctic Glaciers Melting At 20 Times Former Rate, Rock Analysis Shows
If the glaciers are melting at such a high rate as is claimed, how come the sea levels are not rising at unprecedented rates?
Oh wait, they lied right.
Take a look at the graph. Hard to argue with that kind of fit.
Why is it that anyone who disagrees with you has been lied to, yet guys like Hansen are so perfect?
Neither is true. You’re just frustrated and lashing out.
(Swiftboating stuff about Hansen)
Sorry. No bunny trails.
