Scientists who study forests say they've discovered something disturbing about the way prolonged drought affects trees.

It has to do with the way trees drink. They don't do it the way we do — they suck water up from the ground all the way to their leaves, through a bundle of channels in a part of the trunk called the xylem. The bundles are like blood vessels.

When drought dries out the soil, a tree has to suck harder. And that can actually be dangerous, because sucking harder increases the risk of drawing air bubbles into the tree's plumbing.

There's mixed reaction this afternoon to the news that BP has agreed to a deal with federal authorities to pay $4.5 billion in criminal and civil penalties related to the 2010 Gulf Oil spill.

San Antonio Water System customers could be facing a rate increase of nearly 10 percent in 2013. An aging infrastructure is one reason, but another is pressure from the Environmental Protection Agency.

SAWS spokesperson Anne Hayden said each year the EPA targets cities to reduce sewage overflows. San Antonio treats more than 250 million gallons of sewage each day. Hayden said 99.9 percent of that sewage never escapes the system, but the EPA wants even better numbers for compliance with the Clean Water Act.

Update at 11:30 a.m. ET: Oil giant BP has agreed to plead guilty to criminal misconduct related to the 2010 Gulf Oil spill and will pay a record $4 billion in criminal penalties, the company just confirmed. And it will pay $525 million in civil penalties in a resolution with the Securities and Exchanges Commission. BP will make the payments over six years.

A Golden-cheeked Warbler and caves over the Edwards Aquifer recharge zone are the subjects of a lawsuit pending against the City of San Antonio, SAWS, and a local developer. 

Members of The Cibolo Creek Conservation Society say they’ve been trying to get the attention of the City of San Antonio, SAWS, or the developer of the new Century Oaks subdivision off Evans Road, but so far haven’t had any luck. They’re concerned about the density of the housing area nestled along Cibolo Creek, the removal of trees, and the endangered species that call the area home.
