fresh water or ocean acidification first. >> reporter: folks you trust every night with the five-day forecast. a recent study found that only 1 of 33 forecasters sur vied believe climate change is caused mostly by human activities. 1 of 4 agreed that global warming is a scam. to find out why, we turn to one of the most prominent of the doubters. >> what are we worried about now? >> you,a meteorological explanation of what happened. >> yes. i believe there may be some linkage to global warming. i think it's cyclical in nature.

separating weather with climate. >> reporter: heidi is a climatologist who used to work at the weather channel. how to she worked for a nonprofit. she says bastardi is right about one thing. the instruments are far more accurate. is this the thind that joe is saying, hey, let's watch this for 30 years and see what happens? >> yeah. >> reporter: can we afford the wait 30 years? >> if you ask a climate scientist, they will say no. this is a forecast that we can ultimately change. the standard five-day forecast is take an umbrella. with climate change, we say if we continue to do the things we're doing, this is the future we'll inherit. >> reporter: yet, a large section of the public clearly remains skeptical. >> attention al gore.

it's global warming up a over the east coast. check it out. the icecaps are melting. the polar bears are dying. >> reporter: a recent study found that 56% of americans don't trust public figures like al gore and sarah palin on climate change as much as they do the local weather forecaster. >> the forecast will show -- >> reporter: and the climate change scientists are scientists. they admit they have not always been effective spokes people. >> i plead guilty. >> reporter: penn state's michael mann had his mails hacked last year. usually this is a smear cape pain. >> i think every inkry said the statements are being taken out of context and used to misrepresent what scientists are

saying. i believe it is a smear campaign. there's no serious debate within the scientific community about human-caused climate change. i see my job as a scientist to make sure that the public discourse is informed. >> reporter: that may be one reason that doubting meteorologist have had such a huge opening to convince the public otherwise. >> i'm a ditch-digging meteorologist. >> reporter: the stakes are much higher than whether to bring an umbrella. >> about that there is no dispute. when we come back, blood diamonds are not just a hollywood creation. see how questions about them
