Sunday’s CSExtra finds an environmental theme in weekend reporting and commentary on space. As temperatures soar in many parts of the U.S., and while Russia and Pakistan face weather extremes, many are wondering if there is a link to global warming. Also, checking out the night sky.
1. From the New York Times: Recent weather extremes, including a heat wave in Russia and flooding in Pakistan, may have ties to global warming, say some scientists, including one quoted from NASA. A similar version of this story from the AP as published in the Los Angeles Times, USA Today and Washington Post appeared in Friday’s CSExtra.

A. From the Houston Chronicle: In an editorial, based in part on the concerns of NASA climatologist James Hansen, the Chronicle warns that global warming is placing the planet in peril. The editorial cites long term trends, rather than recent weather extremes as an underlying cause. But the floods, heat and wildfires certainly grab our attention.

B. From Florida Today: Columnist John Kelly notes the values of satellite remote sensing — using satellites from NASA and other agencies to monitor changes on the Earth caused by weather, changing climate as well as threats posed by terrorists. As dramatic proof of its value, Kelly offers recent photos of a giant iceberg caught on satellite imagery breaking away from the Petermann glacier in Greenland. The iceberg could pose a threat to ships at sea, off shore drilling activities.
