Paleoclimatologyor the study of changes in climate throughout Earth's historyuses evidence found in tree rings, ocean sediment, coral reefs, and layers of sedimentary rocks to determine that current warming is occurring roughly 10 times faster than the post-ice age warming. Easterling, K.E. Climate change is an issue I care passionately about and have dedicated a significant portion of my life to addressing. Read about global initiatives aimed at speeding up the pace of climate action. Precipitation A lthough framing climate change as our biggest problem is not relevant when we look at problems, it IS relevant when we try to find solutions. Changes to Earth's climate driven by increased human emissions of heat-trapping greenhouse gases are already having widespread effects on the environment: glaciers and ice sheets are shrinking, river and lake ice is breaking up earlier, plant and animal geographic ranges are shifting, and plants and trees are blooming sooner. Some communities are projected to possibly end up at or below sea level by 2100 and will face decisions around managed retreat and climate adaptation.

A third of tropical deforestation is concentrated in Brazil, home to the Amazon rainforest, where, deforestation has surged to a 12-year high. You can explore more at the Global Climate Dashboard. Sea levels are rising due to thermal expansion, in addition to melting ice sheets and glaciers, putting coastal areas at greater risk of erosion and storm surge. Globally, a bit more than a quarter of electricity comes from wind, solar and other renewable sources which, as opposed to fossil fuels, emit little to no greenhouse gases or pollutants into the air. /*padding: 35px 35px; Global Change Research Program, Washington, DC, pp. right: 20px; Liberal media outlets have long been infatuated with doomsday predictions about climate change, with journalists blaming a wide variety of sociopolitical issues, like hate speech and terrorism for . } Maycock, and B.C. https://t.co/Pgn8Xucvxz, This was the most anomalous regional extreme heat event to occur anywhere on Earth since temperature records began. 7. } Preliminary insured damage estimates are $3-$5 billion, and total economic damages will be much higher. , 63% of people dont know the difference between the use by and best before dates.
