You’ve already seen the news. February was a record month for global heat. It followed the hottest January on record. Which followed the hottest year (2015) on record. Which follow the previous hottest year (2014) on record. Etc. Etc. Etc.
So, maybe we think: A bunch of scientists are sifting through data from all over the world, and we’re supposed to be alarmed at a few more degrees of heat? Seriously, what does this mean to us? Well, let’s see if we can distill this down to a few key points.
First, these records are not flukes or outliers. Global data has been kept for 137 years. Of all the Februaries over that time, this one ranked #1, unseating last February, the former hot-weather champion.
Worse, it wasn’t just the hottest February. It was the hottest month ever, compared to 20th century averages. And the prior record had just been set only two months earlier, in December.
Worse yet, it continued a ten-month string of record-hot months. Yes, February was the hottest of all 137 Februaries. But January was also #1 for all Januaries. And they were preceded by #1 records in December, November, October, September – and all the way back to May 2015. Something like that has never happened before. Doubters will tell us “The climate always changes!” Not like this. Not always in one direction. Not in lockstep. We’re seeing something frighteningly new.
Second, did you notice the amount of warming? For all land and ocean surfaces, the earth was 1.21oC (or 2.18oF) above the 20th century averages. You may recall that the nations of the world just agreed in Paris on efforts to limit global warming this century to no more than 2.0oC, and to make every effort to keep it below 1.5oC, to spare our fellow humans from the Philippines, Bangladesh and island nations from being inundated by rising seas. Well, already, we’ve experienced a month within a whisker of breaking that 1.5oC threshold.
Worse, if we look at land surfaces alone (where most of us live) the average global temperature was 2.31°C above the 20th century average. Two-point-three degrees. That’s territory we’re not supposed to see in our lifetimes, or even our children’s. But it just happened.
Third, the heat was just about everywhere. Record heat took hold across much of South America and southern Africa, southern and eastern Europe, around the Urals of Russia, and most of Southeast Asia stretching to northern Australia. Here are some examples:
- New Zealand had its second warmest February and second warmest month of any month since national records began in 1909, at 2.2°C above long-term averages.
- In Venezuela and Colombia, the heat was about 3.0°C higher than average.
- Germany ran 3.0°C above average and Austria was a whopping 4.1°C hotter than average.
- Speaking of whopping, Alaska reported its warmest February in its 92-year period of record, at 6.9°C higher than the 20th century average. That’s not a typo. Six-point-nine degrees Celsius, or 12.4° Fahrenheit. That’s more than the difference between the last Ice Age and today’s world.
Fourth, all this heat is destabilizing the Polar regions dangerously. For starters, this winter marks the lowest sea ice coverage ever measured in the Arctic. It’s way less icy than 2012, the previous record year for summer Arctic ice melt. That means that this summer and fall there will be less ice to start with, and the seasonal warmth will have an easier time melting what remains there. Not only that, but less winter ice mean less bright, reflective snow surface, and more deep blue, heat-absorbing water to soak up the sun’s heat, which will warm the region even further.
But an even greater concern is now emerging in the southern Pole, with new warnings about the instability of the West Antarctic Ice Sheet. About the size of Mexico, the ice sheet could raise sea levels by 12 feet or more if it becomes destabilized. Many of us took some comfort in believing that while this will occur in a warmer world, humanity and the rest of creation would probably have hundreds of years to adapt. But new research from scientists at Penn State and UMass now projects that continued greenhouse gas emissions and the resulting heat could disintegrate the West Antarctic sheet in only decades. That would mean that coastal cities like New York, Boston, Miami and New Orleans would be largely inundated during the lifetimes of children born today, with further sea-level rises of one foot per decade thereafter.
But it’s not hotter EVERYWHERE. And that’s actually alarming. There’s one spot on earth where it’s not getting warmer. It’s Iceland, and the North Atlantic Ocean. See that spot of blue on the map? In a warming world, it was cooler there all last year, and in each of several years before that. That region has always been warmed by tropical ocean currents (called thermohaline, or the Gulf Stream) carrying equatorial waters northward along the US East Coast to Iceland, before they dive to the ocean depths and return southward. Scientists have long believed that fresh meltwater from Greenland could slow down the Gulf Stream, trapping hot water off the US coast, and chilling the northern seas.
So what’s the big deal? A little warmer here, and little cooler there? Actually, it’s a very big deal. Warm coastal waters off the American East Coast are what gave us Super-Storm Sandy, but that storm happened when the oceans were cooler than they are today. And warm Icelandic waters have given Northern Europe the benign climate it has enjoyed for millennia. Tinker with the Greenland Ice Sheet too much, and we’ve got something much worse than a few more feet of sea-water on our hands.
Final thoughts from a Christian thinker: So before we hand these climatic records off to the statisticians for filing, maybe we could take a minute to consider where we stand in history. Two centuries after the dawn of the Industrial Revolution, we’ve pumped eons’ worth of carbon – long hidden deep within the earth – back into the atmosphere. As a result, we’re seeing the early results of our planetary carbon experiment: a consistent record of global warming; heat growing at an ever-faster pace; not just here and there, but spread all over the map; and destabilizing the Polar ice sheets, which are raising sea levels and threatening coastal communities. And we’re even seeing signs of disruption in planet-regulating systems like the Gulf Stream.
“Where is God in all this?” asks Christian author Rev. Edward Brown, in his landmark book, Our Father’s World. “God would not allow us to destroy his creation, would he?”
Well, yes he might, concludes Brown, noting that within his sovereignty, God allows us humans a shocking amount of latitude in what we do with our lives – including what we do with his creation. “If we choose to destroy our home,” says Brown, “God will not stop us. Unless, that is, God were to step into history the way he usually does, through human beings who have aligned their lives with him and who are committed to accomplishing his purposes in their own small histories.”
Brown reminds us of God’s answer to Israelite prayers from the misery of slavery in Egypt: “I have heard them crying out…. So I have come down to rescue them” (Exodus 3:7-8).
Phew! So maybe God will rescue our injured planet, just like he did in Exodus! But Brown demands that we read on: “So now, go” he tells Moses, “I am sending you to Pharaoh to bring my people, the Israelites, out of Egypt.”
Go? Who, me? How? What can I do? “I will be with you,” says God to Moses, words taken up again by the resurrected Christ more than a thousand years later: “Go…. And behold, I am with you always, to the end of the age” (Matthew 28:20).
Do you think maybe it’s time for God’s people to hear that call once again?
