Meteorologists should not be put in jail for denying climate change. Although climate change is real, according to an overwhelming number of scientists, and the harm is well-known, jail is too stiff a penalty. The meteorologist may be incompetent, which is not a crime. If the denial was not genuine, the damage to his or her reputation is be sufficient punishment.
Weathermen and women should not be jailed for denying climate change. They should be punished within their field with things such as being discredited or removed from groups or associations. But people also need to take some responsibility for being informed individuals and not simply look to a single source, as obvious as that source may be, for their information. So while it is in poor taste for weather people to deny climate change, this should not institutionalize the sentiment.
The scientific community is far from settled on the issue of climate change. Those who believe in it say that everyone believes in it. Those who don't, say that there is a diverse range of opinions. If people don't like what meteorologists have to say, they should change the people's minds, rather than trying to silence dissent.
No, weathermen and women should not be jailed for denying climate change. They are the front line deliverers of weather-related news, to be sure, but they do no have the resources necessary to enact change on the contributing factors to climate change. Given that climate change is still such a debated topic, putting anyone in jail for denying that it exists will only serve to make more enemies to the cause. Weathermen and women should be very aware of the trends of the global climate including the arctic ice, but that does not give them the resources necessary to propose the policy and governmental changes necessary to slow down the rate of global warming. That responsibility lies with politicians and lobbyists.
