When we think about global warming at all, the arguments tend to be ideological, theological and economic.

The effects of climate change are real and must be acted on.

We now know that we cannot continue to put ever-increasing amounts of CO2 into the atmosphere. Actions have consequences. In fact, the consequences of past actions are already in the pipeline. Global temperatures are rising. Glaciers are melting. Sea levels are rising. Extreme weather events are multiplying.

Climatologists are all agreed that we'd be lucky to see the end of this century without the world being a totally different place, and being 8 or 9 degrees hotter on average.

The increasing frequency of extreme weather events, droughts and floods is in line with what climate scientists have been predicting for decades - and evidence is mounting that what's happening is more severe than predicted, and will get far worse still if we fail to act.

When the President was asked about global warming at a public appearance yesterday, he responded by talking about America's addiction to oil. You make the connection.

I have not been one who believed in the global warming. But I tell you, they are making a convert out of me as these blistering summers. They have broken heat records in a number of cities already this year and broken all-time records and it is getting hotter and the ice caps are melting and there is a build up of carbon dioxide in the air. We really need to address the burning of fossil fuels.

Is it in our national interest to overheat the planet? That's the question Obama faces in deciding whether to approve Keystone XL, a 2,000-mile-long pipeline that will bring 500,000 barrels of tar-sand oil from Canada to oil refineries on the Gulf of Mexico.

The U.S. has historically been the world's largest contributor to climate change.
