Hi, Marc, if CO2 traps heat and warms the world to harmful effects, then definitely Christians have a call to work for a better path. But does it trap heat? The following video shows it happening; you can see it for yourself.
Already we have increased CO2 in the air by 45% since pre-Industrial times, and carbon isotope analysis confirms it's primarily from burning fossil fuels.
No need to fear, though. There are plenty of clean energy options available. In the long run, they are actually cheaper than burning fossil fuels. Even in the short run they're cheaper, if you consider the health costs of fossil fuels.
