Fallacies of climate-change skeptics Thank you for helping to give climate change the visibility it deserves ("Climate change an issue again," Monday). However, mentioned in your editorial without comment is one of the many fallacies used by climate-change skeptics. According to Mitt Romney, "there have been many times in the Earth's history when temperatures have been warmer than they are now. " That is true, but completely irrelevant to our current crisis. It is equally true, but irrelevant, that 650 million years ago glaciers covered the Earth from the poles to the tropics.

CAPE CANAVERAL, Fla. - An unmanned space capsule carrying medical samples from the International Space Station splashed down in the Pacific Ocean on Sunday, completing the first official private interstellar shipment under a billion-dollar contract with NASA. The California-based SpaceX company gently guided the Dragon into the water via parachutes at 12:22 p.m., a couple of hundred miles off the Baja California coast. Astronauts aboard the International Space Station used a giant robot arm to release the commercial cargo ship 255 miles up. SpaceX provided updates of the journey home via Twitter, including a video of the Dragon separating from the space station.

THE PRESIDENTIAL debates had no questions about the environment. I did hear about the future of our families, but Earth is shaping up with no future. Drilling for oil was a pretty big discussion in one debate, but only more drilling. Bacteria and virus are thriving, droughts are becoming more severe, temperatures are rising at an alarming rate, yet no candidate wants to discuss these issues. Studying to become an environmental scientist in college, I know my job outlook is good, but for all the wrong reasons.

ROSWELL, N.M. - Extreme athlete Felix Baumgartner landed gracefully on Earth after a 24-mile jump Sunday from the stratosphere in a daring, dramatic feat that officials said made him the first skydiver to fall faster than the speed of sound. Baumgartner came down safely in the eastern New Mexico desert about nine minutes after jumping from his capsule 128,100 feet, roughly 24 miles, above Earth. Brian Utley, a jump observer from the International Federation of Sports Aviation, said figures show Baumgartner reached a maximum speed of 833.9 mph - Mach 1.24, which is faster than the speed of sound.

THE TAMPA BAY RAYS made Felix Hernandez's perfect game look even more impressive by roughing up the visiting Los Angeles Angels during an impressive four-game series sweep. Matt Moore (10-7) shrugged off home runs by Mike Trout and Albert Pujols on Sunday to win his fourth straight decision, and the Rays beat the fading Angels, 8-3. Tampa Bay tagged Zack Greinke (1-2) and outscored the Angels 37-14 in the series - setting a franchise record for runs in a four-game set. "I really believe that's a testament to our players and the way they are able to put things in the trash can immediately afterwards if something bad happens," manager Joe Maddon said.

NASA has dubbed the Mars landing planned for early Monday morning the "seven minutes of terror" because that's how long the craft has to slow from 13,000 miles an hour to zero. The entry starts with a parachute, then rockets, and, finally, a novel "sky crane" with a cable that will lower a rover the size of a car gently onto the planet's surface. Though previous craft have landed on relatively gentle terrain, this is the first aimed at a precise spot close to more hazardous topography.

LOS ANGELES - SpaceX's Dragon space capsule, which last week became the world's first privately built and operated spacecraft to dock with the International Space Station, is scheduled to return to Earth on Thursday morning. The unmanned capsule is set to splash down at 11:44 a.m. Philadelphia time in the Pacific Ocean hundreds of miles west of Southern California. It will be the culmination of a historic mission carried out by the Hawthorne, Calif.-based company, officially known as Space Exploration Technologies Corp.

Don't look to the heavens for signs of apocalyptic prophecies coming true. But over the next month, the skies will offer several interesting sights, including a solar eclipse and a rare view of Venus crossing the sun. Only one sight, though, will be easy to view here. ( Weather-permitting , of course.) That's Saturday night's so-called "super moon," which will rise shortly before 8 p.m. While it's near the horizon will be the ideal time for viewing, says Franklin Institute astronomer Derrick Pitts.

FUNNY THING about the lists of "helpful planet-saving tips" that show up as Earth Day (Sunday) approaches: They rarely include, much less spotlight, the daily action that could have the most impact: cutting down your meat and dairy consumption. The United Nations has repeatedly stated that we must drastically change our eating patterns, given that somewhere from 18 percent (if you credit the U.N.'s Food and Agriculture Organization 2006 estimate) to 51 percent (Worldwatch Institute's estimate, 2009)
