Despite a half century of climate change that has significantly affected temperature and precipitation patterns and has already had widespread ecological and hydrological impacts, and despite a near certainty that the United States will experience at least as much climate change in the coming decades, just as a result of the current atmospheric concentrations of greenhouse gases, those organizations in the public and private sectors that are most at risk, that are making long - term investments and commitments, and that have the planning, forecasting and institutional capacity to adapt, have not yet done so.

But from an email conversation with Francis, Vavrus, and several other atmospheric scientists this week, it became clear that there may be more questions than answers at this point, given the large amount of natural variability that affects winter weather patterns, and the very short observational record of how the atmosphere responded to extreme losses of sea ice (only five winters of records since 2007).
