Recent evidence suggests that some organisms are already undergoing phenotypic changes as a result of climate change. Researchers Nicholas M. Caruso et al. compared historical and contemporary size measurements for 15 salamander species in genus Plethodon  from 102 populations, discovering that six of the species have shrunk significantly in body...

Research has already shown that there is a relationship between today’s temperature and one’s belief in climate change and global warming. Lisa Zaval, Elke Weber, and Eric Johnson from Columbia University, along with Elizabeth Keenan from the University of California in San Diego, performed five studies to determine how this...
