Higher temperatures mean higher evaporation and thus stronger drought, even if there's same amount of rain.

Higher evaporation means more clouds (somewhere) and more rain (somewhere).

Recent studies show increased snowfall in central Antarctica for instance.

It's entirely possible that global warming has lessened the severity of these droughts. One fallacy of climate alarmists is to never admit that global warming has some positive effects, no matter how few.

If in fact global warming has in effect cancelled the next ice age, that is a giant win!

It is entirely possible, except nowhere it happened in an useful way. Where there is more rain, it tends to fall in bursts, with flooding. Because moister and hotter atmosphere is more unstable, it's basic principle in the meteorology. And the problem is, our agriculture(and not just it) can't cope with that. Proposals to compromise yields to improve land's stability/water retention are met with hostility.

No, instability in climate is caused by many factors but chief among them would be high and low pressure systems colliding with each other. Moister and warmer atmosphere is not difficult to cope with. Produce grows extremely well in the tropics and not so well in Siberia.

No. Sorry. The minor 0.5C warming we've seen pales in comparison to the changes in temperature on even a daily basis not to mention changes in temperature throughout the atmosphere. Rain still very much occurs in the tropics. So much in fact that rainforests form there.

Rain patterns are controlled by ocean and atmospheric currents.

1) The warming is more than 0.5 degrees C.

2) The warming is global, and in addition to changes in temperature on a daily basis.

The GISS temp data has been manipulated [1]. We don't have global temperature data for the land and the sea going back to 1880. The satellite weather era began in the late 70s. Even for land based records, outside of the first world they are very sparse prior to the 1950s. The temperatures had dropped so much by the 1970s that there was an actual ice age scare. They even hired Leonard Nimoy to pitch it. [2] The GISS data set shows this as a blip and it's a sad joke.

Sorry but you are simply wrong. Tony Heller (your first video) has been debunked so many times it's a wonder he still makes videos. If you want to say GISS data is manipulated, please come up with solid evidence from peer reviewed sources. Their methods have been thoroughly peer reviewed, something that cannot be said of Tony Heller.

Why did they hire Leonard Nimoy, not an actual climate scientist? The doomsday ice age scare of the 70s has been exaggerated to the point of breaking. The vast majority of scientific papers in those times showed global warming is the issue. There was some cooling starting in the 40s, mainly due to aerosol pollution of the atmosphere. This issue was tackled. Now we're left with CO2 and other greenhouse gases.

As for the temperature records, please look up how temperature proxies (tree rings, ice cores...) can be used to reconstruct global temperature. It's not like we know the temperature from 2000 years ago because the Romans had a notebook and measurement stations spanning the globe.
