Climate change will force today’s kids to pay for costly carbon removal technologies, study says
The longer humans continue to pour carbon dioxide into the atmosphere, the closer we draw to leaving the next generation with an unmanageable climate problem, scientists say. A new study, just out Tuesday in the journal Earth System Dynamics, suggests that merely reducing greenhouse gas emissions may no longer be enough — and that special technology, aimed at removing carbon dioxide from the atmosphere, may also be necessary to keep the Earth’s climate within safe limits for future generations.
The research was largely inspired by a landmark climate change lawsuit brought by 21 children against the federal government, which is scheduled to go to trial in February 2018, and will be used as scientific support in the case. In fact, its lead author, Columbia University climatologist and former NASA scientist James Hansen, is a plaintiff on the case, along with his now 18-year-old granddaughter.
The new paper argues that the Paris Agreement’s target of keeping global temperatures within 1.5 to 2 degrees Celsius (2.7 to 3.6 degrees Fahrenheit) of their preindustrial levels isn’t strong enough. During a previous warm period in the Earth’s history, known as the Eemian, or the last interglacial period, the planet experienced similar levels of warming, the authors note — and the resulting consequences included the disintegration of ice sheets and six to nine meters of sea level rise.
