HASB board can’t deny climate change
The Hollidaysburg Area School Board recently voted on the use of an advanced placement environmental science book. The book was approved by a 6-2 vote.
However, during the discussion about the book, two board members, Lois Kaneshiki and Ron Yoder, said that they do not agree with the ideas of global warming.
I would direct them to the web-sites of NASA, The Union of Concerned Scientists, The Royal Society, National Geographic, the 1970’s study and report by Exxon Mobile and the scientific consensus of 97 percent of climate scientists around the globe.
According to NASA, the earth’s climate has changed throughout history, equaling seven cycles of glacial advance and retreat in the last 650,000 years. For 800,000 years, up to 1950, carbon dioxide parts per million had remained between 180 to 300 parts per million.
After 1950, they have rapidly escalated to just below 400 parts per million. This rise of CO2 is directly attributed to the industrial revolution. If this rise continues, the atmosphere will become unlivable for most life on earth.
NASA also states that the effects of industrial carbon emissions and other industrial gases are: warming oceans, shrinking ice sheets, glacial retreat, decreased snow cover, sea level rise, declining arctic sea ice, extreme events and ocean acidification.
The international panel on climate change says: “Scientific evidence for warming of the climate system is unequivocal.”
