By Alex Kirby Humanity has now entered a new climate reality era, with carbon dioxide concentrations expected to remain above the level of 400 parts per million throughout 2016 and for many generations to come, the World Meteorological Organization (WMO) said. The WMO—the United Nations system’s leading agency on weather, climate and water—said the globally […]

By Sophie Yeo How do you reduce CO2 emissions? The Global CO2 Initiative is pushing a unique approach: turn them into useful products, then sell them. Based in San Francisco, the company has the ambitious aim to capture 10 percent of global CO2 emissions through carbon capture and usage. While this method is still in […]

Many hail the Paris agreement—set to cross the threshold this week to come into effect—as a panacea for global climate change. Yet tragically, this perspective neglects to take into account the scientific reality of our climate system, which tells a much different story. Our latest research, Young People’s Burden: Requirement of Negative CO2 Emissions, appeared […]

Life evolved to live within limits. It’s a delicate balance. Humans need oxygen, but too much can kill us. Plants need nitrogen, but excess nitrogen harms them and pollutes rivers, lakes and oceans. Ecosystems are complex. Our health and survival depend on intricate interactions that ensure we get the right amounts of clean air, water, […]

Carbon dioxide concentration in the atmosphere stayed above 400 parts per million (ppm) during September—a time when CO2 levels typically hit the yearly low—raising fears that the planet has reached a point of no return.
