This Chart Shows Just How Much Humans Are Driving Global Warming
But a quick look at the science leaves little doubt that the rising temperatures we've been observing for decades now are our own fault.This chart, published by the Intergovernmental Panel on Climate Change, shows two different models of climate change's effects in different parts of the world between 1910 and 2010.
The graphs each present two models: The purple stripes are the climate changes we'd expect from including only natural events, like solar variations, in the model. The pink stripes show the changes in a model that includes human actions, like burning fossil fuels.The black lines show the effects we've actually observed in real life. You can see the real-life effects match up with the pink bars, which are the models that include human-actions.
fourth and final installment in its Fifth Assessment on Climate Change, a compilation and analysis of the best and most recent climate science, conducted by thousands of researchers around the world. Charts like these show how our Earth has already changed and why we need to accept that humans are the cause - but the document also contains a wealth of projections for the future, including rising temperatures and sea levels, and provides firm recommendations on what humans need to do to prevent the most catastrophic effects from happening.
Slashing carbon emissions and switching to renewable energy sources are just a few of the many actions world leaders must take, according to the IPCC - but the first step is acknowledging that climate change is real, it's happening now, and it's happening because of us.
