Dear Future Generations: Sorry (Prince Ea)
The dire impact of human-caused climate change on ecosystems, species, and public health is already well under way, a landmark study published in the journal Science warns.
The study authors analyzed an array of studies showing how climate change is altering the world around us and concluded that the planet’s warming has interfered with more than 80 percent of biological processes, including genetics, body mass, sex ratios, and productivity.
“Climate change has already impacted almost all aspects of life on Earth,” lead author Brett Scheffers, an assistant professor of wildlife ecology and conservation at the University of Florida, wrote in an email.
These changes have occurred after an average global temperature increase of just 1 degree Celsius since preindustrial times. Experts predict that the planet might see 2- to 3-degree-Celsius warming by the end of the century.
It was the first time scientists had analyzed and described all of these changes in their entirety.
...The authors identified a set of “core ecological processes” (32 in terrestrial and 31 each in marine and freshwater ecosystems) that allow for ecosystem functioning and support services to people.
“Of the 94 processes considered, 82 percent show evidence of impact from climate change,” they wrote.
