How much is climate change contributing?

The vast majority of scientific experts say the warming climate has greatly worsened the fire threat. Tropical storms Fausto and Genevieve moved farther north in the Pacific than they otherwise would have because of the warmer waters, setting up the rare lightning outbreak in August, Mr. Covington said.

Ridges of high pressure that block moisture in the desert Southwest have grown stronger due to climate change, too, he added. That contributed to temperature spikes including when the mercury shot up to 130 degrees in Death Valley on Aug. 16, one of the highest readings ever measured on Earth.

As a result, the vegetation is uniformly much drier than it has been in more than a century, allowing fires to plow through everything from the Joshua tree forests of Southern California’s Mojave Desert to the redwoods near San Francisco, said Daniel Swain, a climate scientist at the University of California, Los Angeles.

“There is a sustained background warming all the time, causing that extra evaporation from the soil that is making water not available to plants,” Mr. Swain said. “It is shocking, but not completely unexpected.”

California smoke wafts across Tucson, shading the sky and turning the sun orange when it isn't obscured.

User Guidelines

Please be respectful and relevant. Thought-provoking. Or at least funny.

We want comments to advance the discussion and we need your help. Debate, disagree, yell (digitally) or laugh, but do it with respect.

We won't censor your comments if we don't agree with you; we want viewpoints from across the political spectrum. We're dedicated to sparking an open, active discussion. We believe people with differing opinions can spark debate and effect change.

Comments are open to registered users of TucsonSentinel.com.

Keep in mind:

  • A conversation involves sharing and respect. Support your viewpoint with facts, not attacks.
  • Ask questions. Search out answers.
  • Remember that being part of a community requires tolerance for differing views.
  • We can't ensure that all comments are based in truth. The only comments we endorse are those we write ourselves.

TucsonSentinel.com does not allow:

  • Hate speech. Blatantly racist, sexist or homophobic slurs or calls for violence against a particular type of person, etc. will be removed.
  • Obscenity & excessive cursing. Sometimes a well-placed curse word - if you're creative enough to get it past our auto-censor - can express your point in just the right way. But we say '%*$& no' to cursing for cursing's sake. And lose the explicit sexually-descriptive language. It doesn't contribute to the debate and there are plenty of other places on the Internet to find it.
  • Flaming. During a heated discussion, unkind words may be spoken. We can live with a certain amount of rudeness in the name of provocative conversation, but a pattern of personal attacks (name-calling, mocking, or baiting) is not acceptable nor are threatening or harassing comments. Show some respect, please.
  • Explicit political endorsements. As a nonprofit we can't allow electioneering. Analysis and explanation of political issues and candidates are encouraged, but specific calls to vote for or against a measure or politician should be done elsewhere.
  • Spam. Solicitation of products or services isn't allowed; contact us about advertising, we'd love to talk to you. Links to off-topic sites may be deleted.
  • Copyright or IP infringement. Lengthy quotes and violations of 'Fair Use' aren't allowed. Anything you post should be your own work.
  • Overposting. Don't bore people and waste electrons with identical comments on multiple stories or repetitive comments that don't advance a conversation.
  • Trolling, sockpuppetry, and other abusive behavior. Please don't feed the trolls and don't pretend to be someone you're not.
  • Gossip. Don't bring up others who can't defend themselves. We don't give out personal information; you shouldn't either.

Comments that violate these guidelines may be removed. We reserve the right to make up the rules as we go along.

Flagging

Commentors are solely responsible for the opinions they express and the accuracy of the information they provide. Users who violate these standards may lose their privileges on TucsonSentinel.com.

Sentinel editors can't read every comment. Trolls, spammers and other troublemakers can slide under the bridge. We rely on you to help maintain a healthy conversation - more than likely, you're reading these comments before the editors.

What if you see something inappropriate? Use the 'Flag' button to send it to a moderation queue. Help us out and tell us why you're reporting it; please don't report someone just because you disagree with them. Boy who cried wolf and all that. We'll take appropriate action on violations.

We will not edit comments to alter their meaning or censor comments because of political content.

We will not remove comments solely because they are heartless, cruel, coarse, foolish or just plain wrong. Your disapproval can maintain a decent signal to noise ratio. Ultimately, however, self-policing is the best method.

Bottom line, don't be a jerk.
