We should protect those areas which provide longer term refugees, where velocities are low, and where refugees from climate change may arrive

When we talk about velocity of climate change, we mean the speed and direction of movement of temperature. So when temperature increases in a particular spot, anything wanting to stay at the same temperature as before needs to move to a cooler place. In an area where there is a very flat thermal landscape, or where temperatures vary little from place to place, that cooler place could be a long way away. And so velocity of climate change would be high. Where cooler places are right next door, like up a nearby mountain range or on the other side of an oceanographic boundary, life only needs to move a short distance to follow temperatures over the same time period. So, the much flatter thermal landscape in the ocean tends to increase velocities, and therefore offsets the effect of greater warming on land to bring the velocities for the two environments closer together. By a similar process, reduced seasonal changes in the ocean tend to push up estimates for seasonal shifts to values close to those for land."
