A Bad Day for Climate Change Deniers … And the Planet

Three new studies offer new proof of how bad the earth's fever has gotten

It’s not often that the climate change deniers get clobbered three times in just two days.  But that’s what happened with the release of a trio of new studies that ought to serve as solid body blows to the fading but persistent fiction that human-mediated warming is somehow a hoax.  Good news for the forces of reason, however, is bad news for the planet—especially the oceans.

The most straightforward of the three studies was a report from NASA and the National Oceanic and Atmospheric Administration (NOAA) confirming what a lot of people who sweltered through 2014 already suspected:  the year is entering the record books as the hottest ever since reliable records started being kept in 1880—and the results weren’t even close.

Average global surface temperature worldwide was 58.24º F (14.58º C)—surpassing previous records set in 2005 and 2007—and making 2014 a full 2º F (1.1º C) hotter than the average for the entire 20th century.  And before you say 2º F doesn’t seem like much, think about whether you’d prefer to run a fever of 99º or 101º.  The planet is every bit as sensitive to small variations as you are.

“Today’s news is a clear and undeniable warning for all of us that we need to cut climate pollution and prepare for what’s coming,” said Lou Leonard, vice president for climate change at the World Wildlife Fund.

When it concerns the ocean, what’s coming may already be here.  A sobering study in Nature looked at sea level rise in both the periods from 1901 to 1990 and from 1993 to 2010 in an attempt to sort out a seeming inconsistency: measurements from 622 tide gauges around the world showed that levels had risen 6 in. (15.24 cm) over the past century, but computer models and other tools put the figure at only 5 in. (12.7 cm).  Here too, what seems like a little is actually a lot:  a single inch of water spread around all of the planet’s oceans and seas represents two quadrillion gallons of water.

Finally, according to the journal Science, at the same time sea levels are rising higher, marine life forms are growing sicker, with a major extinction event a very real possibility. All through the oceans, the signs of ecosystem breakdown are evident: the death of coral reefs, the collapse of fish stocks, the migration of species from waters that have grown too warm for them to the patches that remain cool enough.
