Yes. Not only that, but we can’t separate climate change from any single weather event that ever happens, anywhere, no matter what. So just stop saying that we can’t. Here’s a thought experiment to explain why this is true.
Imagine that climate science is like it is today with a few significant exceptions. First, humans never messed with fossil fuel, using only solar energy. If you need to, you can add in that there are only a half billion humans on the planet because birth control was discovered and implemented earlier in human history and everybody has Obamacare. Second, the climate scientists have a thousand, no, make that five thousand, years of instrumental records of the planet’s weather. Third, there has been virtually unlimited access to super computers and the field is advanced 30 years beyond the present. So, climate science is like it is now plus way smarter and more informed with way more information. Also, there has never been any kind of science denialism on my imaginary Earth, so the negative effects of that particular nefarious activity were never felt, never slowed down progress.
One day astronomers, who are also very advanced in knowledge, understanding, and technology, discover a star that is identical to the Sun, and around it orbits a planet that is identical to the earth. Same atmosphere, similar distribution of continents that move around and stuff, same amount of free water and ratio of land to sea, same orbital geometry, etc. There is only one difference between H’Trae, which is what they named this newly discovered planet, and Earth. The Earth has an equilibrium level of 250ppm of CO2 in its atmosphere and H’Trae has an equilibrium level of 500ppm CO2 in its atmosphere.
The astronomers sent a probe to H’Trae which sent back five years of satellite images from the entire surface in a number of energy bands, so there is a pretty good picture of what is happening there. A thousand dropsondes were dropped across the planet at random intervals which gave more direct atmospheric measurements, and then recorded data from the surface for another couple of years, until the H’Traeans found them, one by one, and ate them. So there’s a lot of data.
There emerges a literature, on “The Climate and Weather of H’Trae,” and it is peer reviewed and widely distributed and it matures and becomes part of the Planetary Science body of knowledge.
Then one day somebody comes along, probably on the Internet, the first known Science Denialist, and says “The amount of Carbon Dioxide in the Atmosphere has no relationship to the climate or weather on H’Trae. None. Any given study that looks at climate or weather on H’Trae that does not independently test to see if having 200% of the CO2 on H’Trae as compared to earth is invalid. The role of a doubling of this gas must be demonstrated anew each time it is proposed or assumed.”
What would the Earthlings do that that person? Ignore him, of course, though they might also be amused to see their first Science Concern Troll. If he got really annoying they might send him off to H’Trae so the H’Traeans eat him.
But they would not take seriously the idea that an increase in one of the most important gasses in the atmosphere, which indubitably alters temperature on average across every cubic meter of the atmosphere and every square meter of the surface, which indubitably increases the amount of water vapor in the atmosphere, which seems to indirectly alter the basic nature of major air currents, has nothing to do with the place where the climate rubber meets the temporal road: The weather. It would be an absurd idea.
So why do people keep repeating that as though it made sense?
