BLITZER: Hillary Clinton is talking to tough to a key U.S. ally. Lisa Sylvester is monitoring that. Some of the other top stories in THE SITUATION ROOM right now. Lisa, what's going on?</s>SYLVESTER: Hi, Wolf. Well, in Pakistan, Secretary of State Hillary Clinton is urging officials to deny safe havens to terrorists. The U.S. believes terrorists within Pakistan have been launching attacks in Afghanistan. And the U.S. has also accused Pakistan's top spy agency of helping the terrorists. Clinton met with Pakistan's president and foreign minister. She also held a town hall with members of the public. And global warming is real at least according to a new independent study. Researchers examined 1.6 billion weather reports from nearly 40,000 weather stations. They found reliable evidence of a rise in average world land temperatures of nearly two degrees Fahrenheit since the 1950s. The study also disputes several claims made by climate skeptics. Criminal gang membership is up by as much as 40 percent in the United States in the past three years. A new FBI report estimates there are 1.4 million gang members. This includes more than 33,000 gangs. The largest numbers of gang members are in southern California, Arizona and Chicago. Officials point out that this huge spike could be due in part to better reporting by law enforcement. And Texas prisoners are going to be losing their lunch. In an effort to save money, prisons have cut back to two meals on weekends, just brunch and dinner. The state is trying to save nearly $3 million. Officials are insisting the nutritional value is the same as what prisoners would get in three meals, but could it say Texas should release low level offenders instead of cutting out lunch so no lunch on the weekends anymore in Texas -- Wolf.</s>BLITZER: Lisa, thank you.
