It is a thought I just thought of with all the wonderful attention that climate change has been getting recently. The thought goes as follows: The world has ever increasing entropy as the whole universe has so. With humans adding to this effect even if green house gases curbed due to this fundamental principle energy is always added to the system. So you take the concept of space elevators and use highly thermally conductive carbon structures and heatsink earth with space, I wonder, what effects this would have and at what scales this would have any effect. P. S. If the earth does heat up wouldn't that mean larger creatures would roam the earth kind cool.
