Don’t Believe in Climate Change?

Must admit I’m still stunned when I talk to an actual human being (one who seems intelligent) and they tell me that they do not believe in climate change. Anyone with an 8th grade education who can read should be able to figure out that the evidence is overwhelming.

NASA has this Global Climate Change website and the graphic above comes straight from their page entitled “Evidence.” With all of that extra CO2 in the air — a gas that traps heat in the atmosphere and is a concept even an 8th grader who has been in a hot car could understand — the evidence goes beyond what we can see and experience ourselves. Seeing, analyzing and cataloguing the data from space and satellites is an amazing set of tools to collect it all and prove climate change is real. 

From NASA’s Evidence page:

  • normPage-3Sea level rise: Global sea level rose about 17 centimeters (6.7 inches) in the last century. The rate in the last decade, however, is nearly double that of the last century.
  • Global temperature rise: All three major global surface temperature reconstructions show that Earth has warmed since 1880. Most of this warming has occurred since the 1970s, with the 20 warmest years having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years.6 Even though the 2000s witnessed a solar output decline resulting in an unusually deep solar minimum in 2007-2009, surface temperatures continue to increase.
  • Warming oceans: The oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean showing warming of 0.302 degrees Fahrenheit since 1969.
  • Shrinking ice sheets: The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA’s Gravity Recovery and Climate Experiment show Greenland lost 150 to 250 cubic kilometers (36 to 60 cubic miles) of ice per year between 2002 and 2006, while Antarctica lost about 152 cubic kilometers (36 cubic miles) of ice between 2002 and 2005.
  • Declining Arctic sea ice: Both the extent and thickness of Arctic sea ice has declined rapidly over the last several decades.
  • Glacial retreat: Glaciers are retreating almost everywhere around the world — including in the Alps, Himalayas, Andes, Rockies, Alaska and Africa.
  • Extreme events: The number of record high temperature events in the United States has been increasing, while the number of record low temperature events has been decreasing, since 1950. The U.S. has also witnessed increasing numbers of intense rainfall events.
  • Ocean acidification: Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent.12,13 This increase is the result of humans emitting more carbon dioxide into the atmosphere and hence more being absorbed into the oceans. The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by about 2 billion tons per year.

It might be too late to stop the acceleration in global CO2 levels. When it comes to climate deniers, maybe they will wake up when their crops whither and die due to abnormal heat and little rain, or when the oceans rise and either they’re inundated with water or millions of refugees flood their towns and neighborhoods.

Connecting the Dots Podcast

Podcasting hit the mainstream in July of 2005 when Apple added podcast show support within iTunes. I’d seen this coming so started podcasting in May of 2005 and kept going until August of 2007. Unfortunately was never ‘discovered’ by national broadcasters, but made a delightfully large number of connections with people all over the world because of these shows. Click here to view the archive of my podcast posts.
