Satellites are used to detect and even photograph changes tied to climate, like this collapse in 2002 of the Larsen B ice shelf on Antarctica. Federal government scientists have warned the Bush administration that a move to cut back on satellite observations will jeopardize climate studies.

The Bush administration is drastically scaling back efforts to measure global warming from space, just as the president tries to convince the world the U.S. is ready to take the lead in reducing greenhouse gases.

A confidential report to the White House, obtained by The Associated Press, warns that U.S. scientists will soon lose much of their ability to monitor warming from space using a costly and problem-plagued satellite initiative begun more than a decade ago.

Because of technology glitches and a near-doubling in the original $6.5 billion cost, the Defense Department has decided to downsize and launch four satellites paired into two orbits, instead of six satellites and three orbits.

The satellites were intended to gather weather and climate data, replacing existing satellites as they come to the end of their useful lifetimes beginning in the next couple of years.

The reduced system of four satellites will now focus on weather forecasting. Most of the climate instruments needed to collect more precise data over long periods are being eliminated.

Instead, the Pentagon and two partners — the National Oceanic and Atmospheric Administration and NASA — will rely on European satellites for most of the climate data.

'Serious jeopardy'
“Unfortunately, the recent loss of climate sensors ... places the overall climate program in serious jeopardy,” NOAA and NASA scientists told the White House in the Dec. 11 report obtained by the AP.

They said they will face major gaps in data that can be collected only from satellites about ice caps and sheets, surface levels of seas and lakes, sizes of glaciers, surface radiation, water vapor, snow cover and atmospheric carbon dioxide.

Rick Piltz, director of Climate Science Watch, a watchdog program of the Washington-based Government Accountability Project, called the situation a crisis.

“We’re going to start being blinded in our ability to observe the planet,” said Piltz, whose group provided the AP with the previously undisclosed report. “It’s criminal negligence, and the leaders in the climate science community are ringing the alarm bells on this crisis.”

Bush has repeatedly cited his administration’s record on researching global warming as a response to criticism of his opposition to forced reductions in the greenhouse gases blamed for it. The administration has been spending about $5 billion a year on global warming: $2 billion on climate research and $3 billion on technologies for combating it.

Last week, the president proposed the idea of the 15 largest emitters of greenhouse gases — the U.S. is the largest, followed closely by China — meeting to set goals for fixing the problem while leaving it up to each nation just how to do it.

The problem will be a major topic at this week’s summit of world leaders in Europe.

Bush requested $331 million for work on the scaled-back satellite system next year in his fiscal 2008 budget proposal. Congress has yet to act on it.

Others state same concerns
In early May, the American Association for the Advancement of Science issued a statement complaining that federal government funds for climate science via satellites had declined in recent years.

"The network of satellites upon which the United States and the world have relied for indispensable observations of Earth from space is in jeopardy," the board said. "Declines will result in major gaps in the continuity and quality of the data gathered about the Earth from space."

The National Research Council came to the same conclusion in an earlier analysis, which found U.S. global observations of the environment are "at great risk," and that the next generation of Earth-observing satellites will be "generally less capable" than the current ones.

NASA and NOAA agreed in April to restore sensors that will enable the satellites to map ozone. NOAA Administrator Conrad Lautenbacher said that would give scientists a better idea of the content and distribution of atmospheric gases.

But seven other separate climate sensors are still being eliminated or substantially downgraded by lower-quality equipment to save money, according to the report to the White House. Most of the satellites, which were scheduled to launch starting next year, have been delayed to between 2013 and 2026.

White House science adviser Jack Marburger, for whom the report was intended, acknowledged that climate scientists had been depending greatly on the planned satellites.

'Very concerned'
“We’re obviously very concerned about this,” he told the AP. “It got in trouble and we couldn’t fit all those instruments on it ... leaving us with a number of problems and questions: How do we maintain our momentum in this very important area of science?”

NASA spokeswoman Tabatha Thompson told the AP a final version of the “impacts” report was delivered to Marburger on Jan. 8. It was not made public because it is “a pre-decisional document within the administration,” she said.

NASA and NOAA also are looking for guidance from the National Research Council, which is holding a workshop on the satellites this month. Chet Koblinsky, director of NOAA’s climate program office, told the council the satellites “represented the cornerstone of the nation’s future space-based climate research program,” according to PowerPoint slides obtained by AP.

The delays were caused in part because of problems with an infrared sensor that officials either didn’t monitor closely enough or didn’t bring to the attention of their managers, the Commerce Department’s inspector general reported last year. That report also said a contractor on the project was receiving excessive fees.

The National Polar-orbiting Operational Environmental Satellite System, or NPOESS, was first announced in 1994. It was an effort to combine weather-forecasting satellites operated by the Defense Department and NOAA and add climate data-gathering instruments.

The plans also involved the European Organization for the Exploitation of Meteorological Satellites and the National Space Development Agency of Japan.

By 2005, however, the Government Accountability Office, an investigative arm of Congress, found the costs for the U.S. satellites could run to $9.7 billion and were almost a year and a half behind schedule. The Pentagon last year pegged the cost at $11.5 billion and found that it was further behind schedule.

Jerry Mahlman, a former scientist at NOAA who is now at the National Center for Atmospheric Research, said he and other colleagues warned of problems as far back as 1995.

He compared the preparations for the satellites to a “planned train wreck.”
