What’s happening in California is actually largely a natural process. California has regular droughts, and has had them since before people were living there. They’ve been exacerbated by humans, by first draining most of the marshland that used to make up California, and more recently by farming, but the drought isn’t caused by either.
As well, the problem with solar panels in the Sahara is again, distribution. The countries that occupy the Sahara don’t use up that much energy, nor even the ones bordering them, though in the future Nigeria, Egypt, and some others will have increasing energy consumption. As well, they aren’t that well developed, and all the places that use tons of energy are too far to transport it with our given technology. Europe is the closest, and even southern Europe is just too far away for our cables and batteries.
Solar is being employed successfully in countries like Spain and Germany, though, as well as increasingly in other countries. The point of the Sahara, is, again, distribution. We have the resources, just not any effective way to move them. Yet.
To combat your pessimism, in addition to Spain and Germany, India is looking to greatly increase their solar usage, and many other states are looking to more green energy, and it’s only recently that it’s become good enough to sustain current energy uses, and just as it has reached that goal, green energies now see more investment globally than fossil fuels.
There have always been floods, droughts, and heat waves, and there always be, and while we are worsening them to some degree through climate change, there will be regions that actually **benefit** from climate change (Canada and the Nordics are prime examples, as they are unlikely to experince any great deal of extra flooding, but will see huge new swaths of arable and otherwise usable land that was once frozen).
Humanity is unlikely to go extinct within the next hundred years, at least not from anything foreseeable. Climate change, antibiotic resistance diseases, and other things are threats and can harm us as a whole, but there is little chance of complete extinction.
