Could be fatal for some

(Newser) – Climate change is really jerking animals around—literally. A new international study has found marine life is moving an average of 4.3 miles towards the poles each year, while land animals are moving about 3,280 feet, as ocean and air temperatures rise, the Guardian reports. "We knew that changes were happening, but we didn't expect them to be so pervasive," says a study leader, per the ABC. "We didn't expect to pick up changes in every single ocean and we certainly didn't expect the changes to be as rapid as we're seeing."

The move could prove fatal for some species that can't withstand the cooler waters where their prey might now be, the Guardian reports. "Some species like barnacles and lots of shellfish are constrained to living on the coast, so in places like Tasmania, if they’re already at the edge of the range there’s nowhere for them to go. You could potentially lose those," says Dr Christopher Brown, a researcher from the study. But even if humans change our climate-changing ways now, the sea creatures may have moved another 87 miles by the time it has any effect. "There’s a long lag time," says Brown. "Even if we reduce emissions now then those effects won’t be seen for 20 years or so.”

The greedy corporations along with executives will go first. There will be 316 cities dissapearing over the water, so those greedy voulters will go first. This makes me feel better, they will die in poison they created.

Food for thought. The arctic just had it's shortest summer in recorded history. The least days spent above freezing. There are variables to everything, and it appears that global warming is somewhat self limiting. Our sky has darkened considerably, which is keeping a certain percentage of sunlight from reaching the surface. One other thing is the steady northward advance of green vegetation, which filters carbon dioxide and creates oxygen. There are many variables when it comes to climate science, many still unforeseen. Add to that, the fact that it's out of our control for the most part, and there's nothing to do except adapt and adjust to any changes we face in the future. No chicken little, the sky is not falling.
