U.S. emissions at 1992 level, according to IEA report
Carbon dioxide emissions from the world’s biggest economies — the U.S. and China — dropped in 2016 and didn’t grow in Europe, showing that economic growth can occur without an increase in heat-trapping pollution, according to the latest emissions report from the International Energy Agency.
Climate models may need revision based on new findings
Terrestrial plant growth may not be responding to increased atmospheric CO2 in the way many scientists expected, a new study by the Institute on the Environment says.
Many climate models projected plant growth would increase, thereby offsetting at least part of human CO2 emissions. But the new research, based in large part on satellite data, concluded that current model estimates of plants’ ability to offset growing greenhouse gas emissions may be unrealistically optimistic.
Coral reef erosion is likely to outpace reef building this century

FRISCO — The legacy of historical fossil fuel emissions on ocean acidification will be felt for centuries, an international team of scientists concluded in a new report, warning that the world needs to prepare for major losses of ecosystem services.
If carbon dioxide emissions continue on their current trajectory, the acidity of the world’s oceans may increase by around 170 percent by the end of the century, the report found. People who rely on the ocean’s ecosystem services — often in developing countries — are especially vulnerable.
