Dedicated to the balanced discussion of global warming
There has been some talk in the press and on some of the blogs that it is too cold in the last couple years to have a global warming trend. Some even say that the warming trend is reversed and it is now going to get colder. There are a variety of people that discuss that the ice caps are re-freezing after having melted which signals that global warming is reversing. Some talk of a local low record that was set at some airport.
The reality is that much of this talk is about weather and not about climate. It is not possible to measure climate within a couple year span. It takes much longer than that to eliminate the various highs and lows from the trend so most climatologists suggest 5-10 years (or longer) before anything is really called climate.
To make matters worse, even the weather may not be the major influence on the arctic ice – it may be the ocean currents which probably have no relationship to global warming.
So go ahead and curse while you dig out your driveway from that major snowfall. Make sure you take cover from any tornadoes and hurricanes that are coming your way. And be careful how much you water your lawn in the dry period in the summer. Their presence means almost nothing in the global warming discussion although it surely will affect your day in a meaningful way.
