New National Climate Assessment Shows America on Course for Unprecedented Warming | WRI Insights

New National Climate Assessment Shows America on Course for Unprecedented Warming | WRI Insights | The Glory of the Garden | Scoop.it

A new federal report reveals alarming statistics on climate change. According to the 3rd National Climate Assessment, released in draft form today from the U.S. Global Change Research Program, the world could warm by more than 12°F by the end of the century if action isn’t taken to reduce greenhouse gas emissions.

 

“The evidence is clear and mounting,” said WRI’s president, Andrew Steer, in response to the report. “The United States sits at the center of the climate crisis. Record heat is devastating crops, rivers are drying up, and storms are bearing down on our cities. Climate change is taking its toll on people and their economies, and will only become more intense without a strong and rapid response here in the United States and around the globe. It’s not too late to take action, but given lags in policy and geophysical processes, the window is closing.”

Fertilizer use responsible for increase in nitrous oxide in atmosphere

"The new study, reported in the April issue of the journal Nature Geoscience, uses nitrogen isotope data to identify the unmistakable fingerprint of fertilizer use in archived air samples from Antarctica and Tasmania. Our study is the first to show empirically from the data at hand alone that the nitrogen isotope ratio in the atmosphere and how it has changed over time is a fingerprint of fertilizer use," said study leader Kristie Boering, a UC Berkeley professor of chemistry and of earth and planetary science."
