TEXTO:
A climate of agreement
In the not-too-distant past, the tobacco industry
funded scientists who raised the shadow of a doubt that
the shadows on people’s lungs were cancers caused by
smoking. There were other causes, they said. And many
[5] people who wanted to believe them did so, kept smoking,
and died. Today those who don’t want to believe that
climate change is caused by human activities keep
saying there’s no consensus among scientists. Well,
that’s just not true. It’s been proven again and again that
[10] a great majority of scientists have concluded there is a
casual connection between human activity and global
warming. Now the journal Environmental Research
Letters has published a careful new study of thousands
of peer-reviewed papers showing that when scientists
[15] take a position on the issue, a full 97 percent blame
human causes. This is important because press reports
that cite doubters representing “the other side of the
question,” without saying how minuscule the proportion,
have convinced the public there’s an even split. There
[20] are many issues on which scientists really do disagree,
like the specific link, or lack of it, between global warming
and killer tornados. But about the general cause of the
warming itself, there’s barely any dissent at all.
