You might first notice that assertions supporting global warming mainly concentrate on the loss of animal species, temperatures increasing, the melting of glaciers, and the rise in water level. However, science acknowledges that our planet has suffered lots of natural warming and cooling stages, entailing five crucial ice ages in its 4.5 billion year lifespan.
You may not know that between 1300-1870, the planet already underwent what scientists tagged the Little Ice Age. Thus North America’s annual average temperature declined to 3.6°F says the New England Historical Society. The reality remains that these natural temperature alterations impacted the ecosystem of all existences within the earth. Therefore, these factors scientists pinpoint in global warming education publications don’t substantiate the certainty of anthropogenic global warming.
