Despite calls by the scientific community for the world to dramatically cut greenhouse gas production to address the problem of global warming, worldwide carbon dioxide emissions rose by 2.7 percent over the course of 2018, the largest increase seen in seven years. This news follows a series of call-to-arms warnings released by the United Nations’ Intergovernmental Panel on Climate Change (IPCC) and the U.S. Government’s National Climate Assessment, warning of the urgent need to cut emissions; additionally, a prediction from the National Oceanic and Atmospheric Administration (NOAA) forecasts that El Niño conditions are very likely to form in the Pacific Ocean over the winter — conditions that may push 2019 into being the hottest year on record.

NASA reports that a recent lull in the sun’s activity did not prevent the Earth from absorbing more solar energy than could escape back into space. This means that climate change is mainly caused by human activity–not the sun, as some people would like to think.

This imbalance (more energy coming in than leaving) is what drives global warming, and because it occurred during a period when the sun was emitting comparatively low levels of energy, it means we have to clean up our act and curb greenhouse gases. read more
