Not to mention that China uses high sulfur diesel in all of it's trucks which is as much as 10x as polluting as that used in the US and the EU. This is due to government mandated price controls on the cost of diesel in order to keep the economic engine moving which in turn forces Chinese petroleum companies to purchase low-quality base stocks to refine fuel from. Plus, with the switch in India from a heavily state controlled economy to free markets, that nation is likely to see similar economic growth given it's population size.
Also, there is the question of HOW and WHERE temperatures are being measured. Many official readings are taken at airports which are in cities. Now cities suffer from the urban heat island effect where the air temperature inside a major urban area can be 5-10 degrees hotter than the surrounding countryside. This is due to the excess of concrete and asphalt which radiates heat back into the air during the night thus causing a somewhat misleading higher minimum temperature reading. These readings are then used by global warming alarmists to say the earth is not cooling sufficiently at night when all it is is the location of the weather station that has been affected, not the whole planet.
Now on to hydrogen. The big question with hydrogen is not weather or not the end vehicle is a gross polluter, it will not be. The bigger issue here is about the net effect of the whole hydrogen cycle from breaking the hydrogen from whatever base material you choose to use to transport to the fueling station, etc. The thing is, if you break hydrogen from water to generate it and then have it rejoin free oxygen in the atmosphere, how much energy did it take to break it initially and then what kind of energy did you use? Also, if using a base stock other than water (I.E. Hydrocarbons) what happens to the atmospheric moisture levels with all of this additional water being pumped into it? Will this not also cause significant environmental changes by increasing worldwide cloud cover? So clearly, it is not the solution unless these issues can be addressed.
Now on to Volcanism. Medium sized volcanoes like Mt Pinatubo periodically release huge amounts of CO2 into the atmosphere, sometimes equal to the total amount of mankind's production over the course of the entire industrial revolution over an extremely short period of time. Yet, following these eruptions, there is not a huge rise in global temperatures. Why? Could it not be that natural forces exist that balance the temperatures and negate the effects? Then, could it not be postulated that these same forces could also counteract the man-made production of CO2?
