I mentioned this last week and its approach (via National Geographic):
An instrument near the summit of Mauna Loa in Hawaii has recorded a long-awaited climate milestone: the amount of carbon dioxide in the atmosphere there has exceeded 400 parts per million (ppm) for the first time in 55 years of measurement — and probably more than 3 million years of Earth history.

And this is just the beginning, folks (Grist): â€œIf you start turning the Titanic long before you hit the iceberg, you can go clear without even spilling a drink of a passenger on deck,â€ said Richard B. Alley, a climate scientist at the Pennsylvania State University. â€œIf you wait until youâ€™re really close, spilling a lot of drinks is the best you can hope for.â€
Of all the breaking news stories, this one is really not braking.
