It was prepared by David Easterling and Tom Karl, National Climatic Data Center, Asheville, N.C. 28801. One of the most vigorously debated topics on Earth is the issue of climate change, and the National Environmental Satellite, Data, and Information Service (NESDIS) data centers are central to answering some of the most pressing global change questions that remain unresolved. Listed below is information based upon common questions addressed to climate scientists (based on IPCC reports and other research) in common, understandable language.

A Scientist, His Work and a Climate Reckoning Jonathan Kingston/Aurora Select, for The New York Times KEEPING WATCH The Mauna Loa Observatory, at an altitude of 11,135 feet above sea level in Hawaii, has been continuously monitoring and collecting data related to climate change since the 1950s. More Photos » They make no noise. But once an hour, they spit out a number, and for decades, it has been rising relentlessly. The first machine of this type was installed on Mauna Loa in the 1950s at the behest of Charles David Keeling, a scientist from San Diego. Yet, five years after Dr. When Dr. By 2005, the year he died, the number had risen to 380 parts per million. The greatest question in climate science is: What will that do to the temperature of the earth? Scientists have long known that carbon dioxide traps heat at the surface of the planet. Fossil fuel emissions, they say, are like a runaway train, hurtling the world’s citizens toward a stone wall — a carbon dioxide level that, over time, will cause profound changes.
