It's the long-term trends that are important; there are random year-on-year fluctuations. However, as the page I linked to states, the long-term trends, as measured by numerous different types of data, are all towards an increase in global temperatures which is unprecidented over the last few thosand years, and the current levels of CO2 in the atmosphere far exceed the natural variability over the last half million years or so.
With respect, you may believe that the data don't support the conclusions, but the majority of experts in the field disagree with you.
To reiterate, every other industrialised nation in the world considers this to be a vitally important issue. It's far too important to play "political football" with.
