![]() The report also finds that climate change is already impacting agriculture, forestry, fisheries, and aquaculture, including in North America. Of particular concern, she adds, is that this relatively small amount of warming has been enough to begin melting permafrost, drying out peatlands, and damaging forests through insect pest outbreaks and wildfires. ![]() According to Camille Parmesan of the University of Plymouth’s Marine Institute, who was co-author of the report’s 35-page “Summary for Policymakers,” “one of the most striking conclusions of our report is that we’re seeing adverse impacts that are much more widespread and much more negative than expected” at that level of temperature increase. ![]() To date, greenhouse gas emissions have resulted in a mean global temperature increase just shy of 1.1 degrees Celsius (about 2 degrees Fahrenheit). Many climate change impacts are worse than thought The report, Climate Change 2022: Impacts, Adaptation and Vulnerability, was published on Monday after approval from 195 governments. And while measures to limit the impact of climate change do exist, the only truly meaningful step is to reduce greenhouse gas emissions as soon as possible.Īccording to Kelly Levin of the Bezos Earth Fund, a foundation that funds efforts to combat climate change, the report “shows clearly how much we need to change course, because delayed action risks triggering impacts that are so catastrophic that our world slowly becomes unrecognizable.” The poor, the very young and very old, ethnic minorities, and Indigenous peoples are at most risk. If warming is not halted soon, and it continues, as many as half the species living on land could become extinct, malnutrition in parts of the world will likely become widespread, and extreme weather events will become increasingly common. The new report found that droughts and heat waves are killing off trees and corals sea level rise is forcing people in vulnerable areas to leave their homes and extreme conditions may be increasing the likelihood of violent conflict. Climate change is causing greater impacts than expected at lower temperatures than anticipated, disrupting natural systems and affecting the lives of billions of people around the world, according to the latest report from the United Nations’ Intergovernmental Panel on Climate Change (IPCC).
