Oh ho ho. But it might be worth distinguishing between (1) "temperatures over the last few years have been decreasing" and (2) "the longer-term trend, of which those last few years are a sample, is downwards", because #2 would mean that global warming isn't a problem after all and #1 wouldn't. And I'm afraid the recent history of people with a very decided political agenda declining to distinguish between #1 and #2 even when the short-term trend in question consists of one slightly colder-than-average winter takes some of the fun out of your ironic wit, for me.
