 Not Like My Father's

Published: June 10, 2013
How to cope with a climate that is not stationary is a major challenge for agriculture (and engineering). Deep within our planning for the future is the assumption that weather will remain the same – it will be like our father’s and mother’s weather. This is no longer the case.

This little vision I have into the world, that my weather has been beneficent, really has little relevance to whether or not the climate is changing. My little vision is no different than that of all of the people who have looked at the cold U.S. spring of 2013 and stated that as evidence or proof that the Earth was not warming. You have to look at all of the Earth and look at what is happening in the oceans and look at all that is melting.

Wunderground's Climate Change Position
Earth's climate is warming. This time, humans are mostly responsible, and the overwhelming majority of climate scientists agree. Climate change is already causing significant impacts to people and ecosystems, and these impacts will grow much more severe in the coming years. We can choose to take economically sensible steps to lessen the damage of climate change, and the cost of inaction is much higher than the cost of action.
