Direct from the warren, and important enough to be worth raising:
If you have been around the Climatosphere for a while, you will already know how important it is to climate science to have reliable, long-term data sets to work with.
One of the most iconic images, seen many times over, on the 'net, is the one which shows the continuous record of CO2 atmospheric concentration, the Keeling curve:
This data set and the measurements which underlie it, is at threat of being broken for a while due to recent funding changes and delays in securing funds for its continuation. The Scripps Institute has started a public fundraiser to cover the shortfall.
Why should it matter? Because it is difficult enough to achieve public recognition of AGW without making a mess of the important work which lies at the heart of the science, as well as the public outreach. Because we need to know. Because the best science (and climate change projections) comes from the best observations.
If you understand the importance of us having datasets like this, and the importance of consistency and continuity, I follow Eli in suggesting that you may wish to make a small donation. This process has been shown to be effective and the 'cause' in this case is eminently worthy. Give if you can, and promote publically.
