Rush Limbaugh doesn't think we exist. In other words that evangelical scientists cannot subscribe to the evidence of global warming.
Specifically, during a recent segment on his radio show Limbaugh stated, "If you believe in God, then intellectually you cannot believe in manmade global warming."
Talk radio personalities often make hyperbolic statements. It is what their listeners expect and want to hear. But in this instance, Rush's uninformed rhetoric is demeaning to Christians who care deeply about what humans are doing to God's Creation and ignorant of the consequences that future generations will face if we don't respond quickly to the challenge of climate change.
We are both atmospheric scientists who study climate change, having earned advanced degrees in our respective fields and having devoted our lives to increasing knowledge through scientific research. We know climate change is real, that most of it is human-caused, and that it is a threat to future generations that must be addressed by the global community. We are also evangelical Christians who believe that God created the world in which we live.
From the very beginning of the Bible, the goodness of God's Creation and God's love for people is front and center. In Genesis, humans are tasked with stewardship of the earth and its creatures. The Psalms praise the beauty of the earth. The gospels exhort us to love our neighbors as ourselves. The epistles emphasize the importance of caring for those in need. It is hard to read through Scripture and not be convinced that caring for people and for the environment in which we live is part of our vocation as humans. It is something we are called to do in order to live faithfully in the world.
These convictions led us to join with 200 evangelical scientists in urging Congress to take action on climate change. Earlier in July, we sent congressional leaders a letter stating, "All of God's Creation - humans and our environment - is groaning under the weight of our uncontrolled use of fossil fuels, bringing on a warming planet, melting ice, and rising seas. The negative consequences and burdens of a changing climate will fall disproportionately on those whom Jesus called 'the least of these': the poor, vulnerable, and oppressed."
For us, global warming is not a matter of belief - it is about applying our understanding of science to the climate of this planet. The author of Hebrews tells us, "faith is … the evidence of things not seen." We believe in God through faith. Science, on the other hand, is the evidence of our eyes. We can measure the extent to which natural levels of heat-trapping gases in our atmosphere regulate and maintain our climate. We can track how excess heat-trapping gases, beyond what would naturally occur, are being added to the atmosphere every day by human activities. We can calculate how this artificially warms the Earth's surface, increasing risks of extreme heat, rain, and drought. We can see how these impacts often fall disproportionately on those with the least resources to adapt, the very people we are told to care for by our faith.
While our expertise allows us to understand the complexity of a changing climate and its causes, it is our faith that compels us to speak out and motivates us to push forward despite the opposition from voices like Rush Limbaugh and gridlock in Washington.
We were appalled at the ignorance behind Rush Limbaugh's statement but we weren't surprised. One of us had previously been dismissed by him as a "climate babe."
