Yes even in the Detroit area where I live close to the weather is just the same as always ,with lush summers and mind winters , so and when they take the coal out it will just get less rain with less dust from coal .... I believe that the scientist are getting rich of the backs of poor people with climate change fear
Are you certain of this? Is this stated by Berkeley Earth? If that's the case, that would be ridiculous.
Yes, if you scroll down it says one station within 1500 km; there's still some correlation in anamolies over that distance (a warmer than average year in Boston is likely to be a warmer than average year in Chicago — their method relies on correlation over distances).
The error range is huge for the 1700s because obviously the correlation isn't that strong. Still might be enough to estimate Chicago had a cold decade in the early 1800s.
Areas that have seen the most warming are the high latitudes of the Arctic. Twice the rate elsewhere. Is that co2? Ocean cycles? The sun? Or a combination? It seems that the evidence is mounting that carbon dioxide plays a major role in regulating the earth's climate over long periods.
The high latitudes seem to just change faster than the globe overall (in warming or cooling spells); regardless of the cause (sun, CO2, etc). Some of it is changing snow and ice cover = more sun reflected or absorbed. Don't think it's the only reason, northern Europe isn't that snowy and has lots of change. Though perhaps it affects airmasses further downstream.
CO2 levels must of melted the mile thick ice covering Chicago 20,000 years ago
I promised myself not to contribute to this thread with some Ludacris comments. So have fun everyone.
I saw a graph that showed co2 levels actually follow temp rise. Temps for the holcene peaked 7000 years ago but co2 continued to rise after that. Also naturally the earth should be cooling as we have past the peak warmth of this interglacial. It is cooling if we look at the long term for the holcene slowly we have been cooling.
As you can see in this graphic there have been times where co2 rose as Temps plummeted. The graphic below shows that we have gradually been cooling the past few thousand years ever since the climate optimums. Every warming event has been getting weaker and shorter lived.
I'm not denying we are warming now because we clearly are but I just wanted to throw these out here.
This chart below shows winter temperatures in Chicago since 1872. A skim of this chart shows, basically, no trend. I suspect the same can be said of most if not all inhabited areas. The global warming or "climate change" alarmists will show us charts of "world" or "global" temperatures.
Can any show a chart like the one below where temperatures have shown a general pattern of increase based on consistently maintained records?
1. It isn't a chart it's a table.
2. Where is the data from?i.e. Which stations?
3. How does it determine winter temps? Average oh highs? Average of lows? From when to when?
4. What is the variance?

Yes Co2 can be both causal and an effect of climate change. For example the current heating is causing permafrost to melt which is releasing co2 and methane back into the atmosphere. So?
As for your second graph no info on where data is from, which proxies were used, and where the variance went. It's crap.
I saw that graphic also. Still shows a cooling trend for the past few thousand years ever since the climatic optimums. Those climate optimum were the best for the globe. Saudi Arabia and much of the Sahara became greener as more rain fell. Much of Saudi Arabia was a savanna type landscape that got enough rainfall to support rivers and lakes even. I wish we could return to a warmer time period like that. Some people claim that we are currently warming out of a 2.6 million year ice age and this is it. I'm not so sure as we are still fluctuating between milankovitch cycles with the northern hemisphere summer slowly getting shorter.
