Science is about generating hypotheses, then determining which are incorrect. Many things we take for granted in science now sounded too fantastic to believe when they were proposed. Quantum physics, plate tectonics, and ulcers caused by h. pylori are three examples that come to mind. On the other hand, you shouldn't blindly believe any new hypothesis just because you like it -- you should demand evidence before you accept a new idea.

Everything is nothing more than an honor system. You trust the operating system to accept only the password you chose when someone tries to log in to your account. You trust the compiler not to secretly install backdoors into software. You trust the hardware manufacturers not to implement secret knocks to allow backdoor access. You trust your browser to handle SSL certificates appropriately. If you don't like it, you can build your own hardware and software from scratch and feel safe in the knowledge that it's secure. That is, if you trust that you didn't make a mistake.

I don't think they have agreed it's the most cost-effective solution. I think the bottom line is that they agree that the effects of a warming of 2 degrees Celsius are so bad that we should try hard to avert it. We don't have the technology to remove enough carbon dioxide from the atmosphere to meet that goal, so the only option is to reduce emissions. Now, if you have a better idea, please speak up!

We're putting 30 billion tons of carbon dioxide into the atmosphere each year. At that rate, every person on Earth would be responsible for creating nearly 5 tons of tree each year to eat up all that carbon dioxide. I don't think there's enough space on land for that, even if everyone could plant trees that fast.

"They" didn't change "it". Global warming means exactly what it sounds like it means: the Earth is getting warmer on average. Climate change means all of the associated changes in the climate that go along with increased temperatures, such as increased drought in areas that are prone to drought. And you're right that global warming doesn't mean that it will get warmer everywhere, because at first some places will become cooler. However, as global warming progresses, it will eventually be hotter on each place on Earth than it was in the early 1900s.
