"We are now faced with the fact that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history there is such a thing as being too late… We may cry out desperately for time to pause in her passage, but time is deaf to every plea and rushes on. Over the bleached bones and jumbled residue of numerous civilizations are written the pathetic words: 'Too late.'"

- New paper, developing methods for climate change velocity algorithms for conservation and management, accepted for publication in Global Change Biology.
- I will be attending and presenting at the IUFRO 2014 World Congrees in Salt Lake City, Oct. 5-11, 2014.
- The AdaptWest data repository now contains a variety of climate and other derived landscape data, including some velocity of climate change metrics, related to the research I am doing at UofA.
I currently study the effects of climate change on forest ecosystems: past, present, and future. Over the last two million years, the evolution of North American tree species, subspecies, and genetic varieties has taken place in a constantly changing landscape often dominated by extensive ice sheets and restricted temperate climate environments. I employ species distribution models (ecological niche models) to reconstruct past and project future tree species distributions throughout western North America, using patterns of past species distribution and migrations to inform conservation and management expectations under climate change scenarios. I also look at how variable velocities of climate change (movement of similar climatic environments across the landscape) may affect forest ecosystems and genetic populations. More detail here.
