Short term weather in one place can overpower global warming - for a short time. But long term we're going nowhere but up, until we take serious action.
This graph shows it nicely. Even some whole years are unusually warm (1998), some unusually cold (1999). But the long term trend is undeniable, unless you reject science and data.

Of course some do reject science and data in favor of weird conspiracy theories. Like people who say we didn't go to the Moon. Denying global warming is the same thing. You have to assume thousands of scientists and most all world leaders are involved in a strange conspiracy. Ridiculous.
