Hi,i want to ask a question.is there any chance that the global warming can conjure gigantism and global radiation of reptiles just like million years ago?or is the global warming trigger the opposite effect,since i recall a species of lizard(a spiny iguana or chuckwalla if i remember correctly) suffer a local exctinction because of the rising remperature.so,are there any chance human can live alongside giant reptiles?tganks

Well in the short term rapid climate change is likely to kill a lot of species if they cannot adapt well to the changing conditions. However, long term yes, if the temperature remains both stable and high, it is the right conditions for large reptiles to evolve (especially things like snakes) though of course what else is happening to the environment through human action could easily stop it happening.
