When we see records being broken and unprecedented events such as this, the onus is on those who deny any connection to climate change to prove their case. Global warming has fundamentally altered the background conditions that give rise to all weather. In the strictest sense, all weather is now connected to climate change.

Connie Barlow & the Torreya Guardians: Helping Plants Move North in Anthropocene Climate
http://www.youtube.com/watch?v=N_9SCSB5wfM
Climate is warming too fast for large-seeded plant species to migrate north via the animal partners (e.g., squirrels) that have dependably dispersed seeds for millions of years. In July 2008, a group of citizen-naturalists (Torreya Guardians) legally acquired 31 seedlings of the most endangered conifer in the world — Torreya taxifolia (the "Florida Torreya") — and then planted the seedlings beneath wild forest canopy on two private properties in the mountains of North Carolina. In this richly illustrated, 75-minute videoblog, the founder of Torreya Guardians (Connie Barlow) reports in November 2013 on what they have learned thus far — and the frightening implications for how even common plants will soon require human assistance for keeping pace with human-caused climate change.
