With a scale from 20 to 80 F, it's not so easy to see the 1.5 degree increase. How about if we take the same data, average each year, and plot: Oh, look, there's been a 1.5 degree increase in the yearly average! And all we did to clarify the increase was to change the plotting parameters a little bit.
@hippyjoe1955 says [quote]The chart I posted is way too short to draw any conclusions but here you want to shorten that even more.[/quote] Ah, so you want data covering a longer time? How about seven ice ages, spanning 800,000 years?
The climate data comes from bubbles in glacial ice, and is corroborated by data from sea floor sediments. CO2 & methane & temp data Here's [i]where[/i] the various data sets were collected: The most salient thing about the 800,000 years of climate data is the rate of change during those previous 7 ice ages compared to the current rate of change this century. Let's zoom in on the most recent ten centuries:
Wow, that CO2 is really out of this world, isn't it??
@ElwoodBlues You still have no idea what a reasonable timeline is do you. This morning I woke up and it was 15 C. By noon it was 22 C. Global warming? Too funny. Science and you are complete strangers.
@ElwoodBlues 1) is there global warming? We don't know. We don't have accurate enough data. 2) If there is global warming what is causing it? We don't know what drives temperature other than sun output and orbital distance. CO2 is NOT a driver given that it was much more common before the ice ages than it is now. 3) What is the ideal temperature? We don't know. We know that warmth is better for life than cold. After that your etch a sketch science just looks stupid.
@hippyjoe1955 "You still have no idea what a reasonable timeline is do you. This morning I woke up and it was 15 C. By noon it was 22 C. Global warming? Too funny. Science and you are complete strangers. " omfg - Statistics and you shall never cross paths, less alone look in the dame direction. You look down at your feet and see they're firmly planted in the ground so that's enough for to say everything is a'ight.
@Phoenix If the earth is billions of years old and the CO2 levels were at 6000 ppm a few million years ago why are we worried about CO2 levels of less than 400 PPM? Did life cease, the oceans evaporate and the earth burn up when CO2 was 6000 PPM?
@Phoenix Son the past history KNOWN is that the CO2 levels were 6000 PPM. now they are less than 400 PPM. Try to think for once in your life. CO2 is CO2 regardless of what generates it. 1 carbon atom and 2 oxygen atoms make CO2. It is plant food.
@Phoenix What do you think all the limestone is made of? [b]CO2[/b] The CO2 levels in the cretaceous period was about 6000 ppm. It is now around 400 ppm. What happened to all the CO2? The corals etc turned it into limestone. If you don't know that then there is no hope for you and your silly theories.
@hippyjoe1955 Kinda funny to see a guy who so recently assured me the Earth is only 6000 years old now casually refer to a period 140 million years ago. What happened to the 7 day creation, dude?? [quote]Finding stalactites and stalagmites in caves and thinking that that is a measure of how old the cave is is silly if you don't know what the cave looked like when it started. Assuming that the cave was 'caused' by erosion or whatever is also nonsense if you accept the FACT that God created the cave. The plants and animals etc were full grown when they were created.[/quote]
Back to the cretaceous period. Were were sea levels in the cretaceous period? They were high enough to drown all of our sea level cities! Your whole argument here is a giant straw man fallacy where you pretend your opponents are saying high CO2 will kill life. That's just false.
High C02 will flood our cities. That's the disaster we're trying to forestall. And I've explained this to you many times, but you just keep on launching your same old straw man fallacy. [b]SAD!!![/b]
