Can someone explain why aerosols are decreasing in their graph? A definition of what they consider an aerosol would be a good start, which I didn't see on there. Apparently the term can cover a large number of natural and unnatural compositions of matter: https://en.wikipedia.org/wiki/Aerosol

What makes you think so? There's plenty of ways to indirectly know past temperatures, even if there wasn't a human writing it down.
Not with the accuracy and resolution of the data we have since last century. When you compare the current time series with the reconstructed ones from the past, you're comparing a day by day thermometric reading with the assembled averages of multiple, very noisy and extremely low frequency samples. Very tricky to say from those what might have been the actual speed of change in the past.
What makes me mad about these kinds of data based climate change arguments is that they don't engage with the data in an honest way. The huge problem is 1880 was one of the coldest years in history. That cold period was caused by volcanism, several volcanos erupted causing a cold period that lasted from the 1600s to the late 1800s. This period is known as the little ice age. The worst of this period was in 1816 which…

> The only real question is: What are we going to do about it? Zilch, so long as politicians corrupted by the fossil fuel industry are in power. "It is difficult to get a man to understand something, when his salary depends upon his not understanding it!" -- Upton Sinclair
Now in this environment, all the fossil fuel industry has to do is encourage that section of the electorate to continue to believe things they already believe. The fundamental problem here is (in my own humble opinion) the large number of voters with ideological blinders on, and that's the problem that's ultimately got to be addressed.
I was actually at a political event yesterday where some derp derp conservative was going on about how this stuff is all hoax. Meanwhile, we are in upstate NY, in late February, sitting outside enjoying the 80 degree weather which is warmer than Los Angeles.

It's because global warming politics has nothing to do with temperature. The incentive isn't to cool the planet, but alter the world economic model. Whether or not that's a worthy goal is irrelevant -- using the climate to advance that apparent agenda is fraudulent. Here's more on that theory -- with appropriate links to source material from the UN. https://www.reddit.com/r/climateskeptics/comments/441rl6/un_... This…
Maybe that is the UN's position but I think most people just want energy produced cleanly which helps the environment beyond just global warming which is important for long-term economic health. And it will likely reduce respiratory illness.

But increasing amounts of Aerosols causes Global Cooling, not warming, which is why the graph angles downwards.

The sample size of our records is incredibly small when stacked against the history of the earth and all the records we're missing.
We'd be incredibly unlucky to have missed a temperature change as fast as the one we're measuring now, if it indeed would have been caused by a small sample size of past measurements.
