By Ted Stroter, RDA science wizard and all-around nice guy Global warming and climate change are used interchangeably. I personally believe “climate change” is a better descriptor of what is happening to our planet and atmosphere. Let’s examine a few key facts:
- Globally, the 10 hottest years on record have occurred since 1998, with 2016 being the hottest ever. It should be noted that global temperatures are measured each year by 5 separate agencies from 4 different countries, all of which show this warming trend.
- The Alaskan Iditarod dog sled race has been ongoing since 1973, over 40 years. For the second time in 3 years, there was too little snow on the course this pst winter for the race to be safe! The race start had to be moved 300 miles north.
- On March 7th of this year, sea ice at both poles reached their lowest level ever recorded. This is significant, as Antarctica ice has appeared to be growing in past years and some climate deniers have used that as an argument against global warming. The increases in Antarctic ice have always been far exceeded by decreases in Arctic ice. Antarctica and the Arctic are two very different environments: the former is a continent surrounded by ocean, the latter is ocean enclosed by land. As a result, sea ice behaves very differently in the two regions.”
- Exxon Mobil, now the world’s largest oil & gas company, spent considerable time and money researching climate change in the 1970s and 1980s. But despite the warnings of one of their top scientists on the consequences of climate change if the issue wasn’t tackled soon, the company holds fast to its position that climate science is controversial. Exxon has been at the forefront in questioning the scientific basis for concern about climate change. The company also helped to prevent the U.S. from signing the 1998 international treaty to control greenhouse gases. ExxonMobil shareholders have filed a class-action lawsuit against the company, alleging it misled its investors and the public by failing to disclose the risks posed to its business by climate change.
- US Secretary of Defense James Mattis “asserted that climate change is real, and a threat to American interests abroad and the Pentagon’s assets everywhere” at his confirmation hearing in January: :
- Depending on exactly how you measure the expert consensus, somewhere between 90% and 100% that agree humans are responsible for climate change, with most of our studies finding a 97% consensus among publishing climate scientists.
- The greater the climate expertise among those surveyed, the higher the consensus on human-caused global warming.
