Kudos to Pope Francis for his recent statement on climate change. Some people who deny mankind’s influence on our changing climate use the fact that a few scientists fudged data in order to obtain grants. But there is no denying the fact that the 10 hottest years on record (since 1880) have occurred since 1999, with 2014 being the hottest.

Most Republicans are willing to spend whatever it takes to protect our people from foreign attacks. Yet they balk at expenditures to protect our way of life from the harm we have been doing to our planet. Why is this? I believe it is due to the money that they get from the big fossil-fuel energy companies.

The pope does not have to worry about campaign contributions and is not subject to this lobbying. He has come to the reasoned conclusion that we need to act to preserve the Earth.

People who deny mankind’s effect on climate change are irresponsible and, given the pope’s views, immoral.
