There is no longer any credibility in the denial of climate change.  One might just as well deny the reality of gravity.  Frankly, people who accept the findings of science in all aspects of their lives want to deny what scientists are telling us about our culture of death killing the planet.  Some deniers are simply ignorant of what's happening, while others fear having to change their greedy lifestyles, and still others would rather live in denial than face the truth.  Sadly, so long we delay taking serious action to preserve and nurture the world God gave us, the more people will suffer and die.  19 of the 20 so-called 'G-20' nations recently reaffirmed the reality of climate change and their commitment to the Paris Climate Accord.  One nation - the USA - represented the ignorant, greedy, and those in denial, and denied the reality that climate change threatens all life on the planet.
