I think the reason you don’t hear about global warming anymore is the same reason you haven’t heard much about it for the past 20 years. The media are bought and paid for by the fossil fuel industries, with Exxon and Koch being the most ruthless in their funding of climate change denialism.
I’ve been following the science like a hawk for over 20 years, reading the science in top science journals, and even wrote my thesis – Environmental Victimology – partly on it. What I know is this, the science on anthropogenic climate change (AKA global warming, the greenhouse effect) has become stronger and more robust with evidence from many different sources converging, and the message has gotten more and more dire. We are on the brink of pushing the earth systems into what JPII called “the abyss,” except he naively thought in his statement,
The Ecological Conversion, that we understand this and are stopping short of it. But apparently we are not, since the climate change denialism is growing stronger, as the science on climate change – that it is real and dangerous – is increasing.
As for the supposed cooling – wrong. It’s been warming over the past 60 years, even the past 10 years, when we SHOULD have been cooling. What that means is once the solar minimum cycle is over (with lower irradiance from the sun), then it will really heat up a lot faster as we go into a solar maximum on top of anthropogenic global warming from the greenhouse effect. This does not bode well for life on earth, including human life.
As for me and my house, we will serve the Lord and reduce our greenhouse gases and other harms. I would hope that at least some Catholics would also do whatever they can to reduce their greenhouse gases thru energy/resource efficiency/conservation and going on alternative energy when feasable and affordable. For one thing, it can be done in ways that save money without lowering living standards down to at least a 50% or more reduction. So over the past 21 years we have become richer & are laughing all the way to the bank. Just think if everyone had heeded JPII’s admonition 21 years ago to mitigate global warming (and other serious environmental problems), our economy would have been in much better shape today. However, instead of seeking first the kingdom of God and its righteousness, Americans got into speculating on real estate (used to be called home buying) they could not afford and other greedy endeavors.
So much for living in a “Christian” (and “religious”) country.
The difference between conservatives and liberals is that they will be spending their eternity in much hotter place than a globally warmed world for different reasons.

Let us pray for their souls.
