GAINESVILLE, Fla. — Global climate change has already impacted every aspect of life on Earth, from genes to entire ecosystems, according to a new study by the University of Florida Institute of Food and Agricultural Sciences and in cooperation with a broad international partner group, published in the prestigious journal Science.
“We now have evidence that, with only a ~1 degree Celsius of warming globally, major impacts are already being felt in natural systems,” said study lead author Brett Scheffers, an assistant professor in the UF/IFAS department of wildlife, ecology and conservation. “Genes are changing, species’ physiology and physical features such as body size are changing, species are shifting their ranges and we see clear signs of entire ecosystems under stress, all in response to changes in climate on land and in the ocean.”
During this research, Scheffers, a conservation ecologist, collaborated with a team of researchers from 10 countries, spread across the globe. They discovered that more than 80 percent of ecological processes that form the foundation for healthy marine, freshwater and terrestrial ecosystems already show signs of responses to climate change.
“Some people didn’t expect this level of change for decades,” said co-author James Watson, of the University of Queensland in Australia. “The impacts of climate change are being felt with no ecosystem on Earth being spared.“
