When I look around, the biggest way in which we are failing to care for those in need is through ignoring climate change and acting like it doesn't exist. As a Christian, I believe that is something the church needs to know.

It's easier to deny the reality of the problem altogether than acknowledge that it is real.

One of the biggest issues with renewables right now is the fact that if the wind isn't blowing, if the sun isn't shining, we don't have energy. Many people are working on storage technology so when the wind isn't blowing, we can use the energy stored in our giant batteries, essentially. But what happens if we don't have enough stored energy?

Where I live, if I put solar panels on my roof I'm not allowed to sell that energy back to the grid. I can't change that restriction myself. I need our local decision-makers to fix that.

It's a common perception that science and religion are mutually exclusive. But there are many scientists who would consider themselves to be spiritual people. Not only that, but in the case of climate change - a scientific issue with strong moral implications and difficult decisions to be made - it's essential to connect the science to our values. And for many of us, our values come from our faith.

A person of faith who shares conservative values and who says very clearly that climate change is real - and here's why we have to care about it - I think that we "unicorns" do pose a threat to people who want to muddy the waters and keep others in the dark.

I think it's interesting that the United States and Australia are two of the most individualistic nations in the entire world in terms of national personality.
