I highly recommend signing up for Mary Holland's blog!

One of the comments asked the question can moose move north to regain colder climates.

I looked around for a short time but the information is not very plentiful about the movements of larger animals going north.
They are blocked by highways, developed areas and even the Great Lakes. It also takes them longer to travel when compared to birds, insects and marine animals.

The smaller the animal the faster it moves north. Insects, bacteria and other microbials are probably the fastest moving. Flying birds are also moving north but I didn't see anything about ground birds.

There are lots of reports about marine creatures successfully heading north from warmer waters they are use to but little information about the northern marine creatures moving farther north to get back to a colder environment.

As the land animals that do go north run into animals that already live there, both groups find themselves in competition for the same things.

People are gambling on how little they have to give up. One of the proposed solutions to the declining animal and plant populations is to set aside half the space on the Earth for no development, or undevelopment. All the livestock we grow for our personal consumption does't count towards repopulating the diversity of the planet. If the rule continues that the larger animals are being removed from the Earth at an ever increasing rate for any number of reasons, at some point in time humans will be at the top of the size list. Humans believe they automatically have immunity to this process.
