Polar bear on melting ice: Evidence for the relationship between parts per million of CO2 in the atmosphere and hot, summer temperatures, in the aggregate?

... wondering what the evidence is for the relationship between parts per million of CO2 in the atmosphere

and hot, summer temperatures, in the aggregate,

over, say, the last 50 years ...


In other words, if the current ppm is around 390,

and 350 ppm could mean cooler, summer temperatures

(like in the 1970s on Cuttyhunk MA, in the summer?),

how do we get there,

and how can we find the academic papers that show this relationship,

given the complexity of climate science?


("To preserve our planet, scientists tell us we must reduce the amount of CO2 in the atmosphere from its current level of 392 parts per million ("ppm")to below 350 ppm. But 350 is more than a number—it's a symbol of where we need to head as a planet." from http://www.350.org/ ) ...


Here's World University and School's Ocean and Climate Management Plan, wiki subject page, too ...

Here are some resources about this I just found and added to the WUaS OaCMP page above, and water level has been rising about .3 cm per decade for decades:
