Anyone who reads them should conclude that Fossil Fuel companies have been aware of the reality of Global Warming and the CO2 link, for decades. Most Canadians understand that Climate Change is real because we have seen it for ourselves. My mother in law used to go skating for months every year on Elk Lake, Rithet's bog and Panama flats back in the 1930s. Now those rarely freeze over and not long enough for safe skating. The "Ice Ramming" MV Manhattan had to give up on the McClure Parry passage on both attempts in 1968 and 1969, turning south to narrow, shallow passages too dangerous for routine traffic by supertankers, and well within Canadian Territorial boundaries. Now McClure Parry melts open safe for non ice strengthened ships every year, like clock work. The Pole will be ice free for 90 days every year within decades, according to the Chief Navigator / Oceanographer of the USA Navy. The 20 meter pressure ridges that stopped the Manhattan are long gone.
