World’s Polluters Escape Detection with Outdated Approach

Sustainability data company Ecometrica called on countries and governments to adopt modern direct methods to measure climate-change emissions, following revelations by the BBC that official figures for emissions of climate-warming gases often are flawed, allowing some countries to underreport the level of pollution. “The time has come to move to direct monitoring of emissions and

First Space-Based View of Human-Made Carbon Dioxide

Scientists produced the first global maps of human emissions of carbon dioxide ever made solely from satellite observations. The maps, based on data from NASA’s Orbiting Carbon Observatory-2 (OCO-2) satellite and generated with a new data-processing technique, agree well with inventories of known carbon dioxide emissions. No satellite before OCO-2 was capable of measuring carbon

NASA Aircraft Measuring Mid-Atlantic Greenhouse Gases

NASA is conducting low-level aircraft flights measuring greenhouse gases over the U.S. mid-Atlantic region for the CARbon Airborne Flux Experiment (CARAFE), which will measure the exchange of greenhouse gases such as carbon dioxide and methane between Earth and the atmosphere. Water vapor, temperature and vertical wind measurements also will be taken. “The direct measurements of

New Laser to Shine Light on Remote Sensing

A revolutionary new type of laser developed by the University of Adelaide is promising major advances in remote sensing of greenhouse gases. Published in the journal Optics Letters, a research team from the University of Adelaide and Macquarie University has shown that the new laser can operate over a large range within the infrared light

Ecologist Advances Understanding of the Role of Greenhouse Gases

A new research paper published in Nature, advances the understanding of how greenhouse gases from forests, grasslands, and agriculture other than carbon dioxide play a role in climate change. The paper, authored by a Montana State University ecologist and nearly two dozen other scientists around the world, takes a closer look at the role of
