I think it would be a good thing for there to be a calm, rational discussion on Earth's climate and what we can do about cleaning up our home, like cleaning up the Great Pacific Garbage Patches. Hat tip to Real Climate Science for the charts and links to the data.
That being said, we can't have that calm, rational discussion because the climate-change scientists are a) always in a panic about the Earth "cooling off to an ice cube" or "igniting into a ball of fire" and b) can't stop altering their data to advance an agenda. You see, I am old enough to remember when climate science first became a thing. Back in the 70's, these climate change scientists were screaming about global cooling and wanted Nixon to cover the polar caps with coal dust to absorb more heat and stave off the coming ice age. Then Al Gore came along in the 90's and started talking about global warming. Just imagine how bad it would have been if Nixon had done what he was asked.
When you are kept in a panic mode by telling you THIS DISASTER IS HAPPENING NOW and WE HAVE TO TRUST THE EXPERTS AND DO WHAT THEY SAY, you tend not to look too closely to the data because you're no scientist and all those numbers mean nothing to you. This means you have to trust the experts, and by extension their credibility and integrity must be pretty much unimpeachable. Which, if you read the rest of my piece, you will find the scientists are sorely lacking in this department.
Now, the terms global warming and global cooling have been replaced with global climate change because that way it can mean whatever anyone wants, sometimes both warming and cooling at the same time. And once again, I call into question the integrity of these scientists because they have altered their data.
This graph illustrates the altering:
In a science where tenths of a degree are big things, this data has been adjusted downwards up to 1.5 degrees before 2000 and adjusted upwards up to a degree since then until now. Because we are talking about a government bureaucracy here, a certain number of weather stations do not report their data. When that happens, the home office has to put an "E" (for Estimated) next to the temperature they think it was, based on their computer models. Between 1970 and 2000, the failure to reports was between 10 and 20%. Since 2000, those estimates have skyrocketed to almost 50%. I'm no scientist, but I wash almost everything but my laundry through a spreadsheet. If 50% of my data was guesstimates, my analysis would be worth exactly Jack Shit.
In the end, a swing of temperatures of that drastic would indicate something. That being said, the actual data does not show that and how accurate can you be about your claims when half of your data is guesses?
