See my comment below for example links to scientific papers talking about the cooling trend. I don't really see why lack of familiarity with the historical facts in some parts of the world should reflect badly on the people who do know them. At any rate, it's not a big surprise. English is the de-facto language of science, the English speaking world has a stronger tradition of free speech and simply has more people who can research obscure topics vs most languages. Also, look at where the global temperature datasets are produced - it's all US and UK universities and agencies. Historical temperature data for much of the 19th and 20th centuries comes primarily from US sources, because for much of the 20th century the rest of the world wasn't running organized weather station networks at all - rest of the world was either dirt poor, being ravaged by world wars or undergoing communist revolutions. The USA has a large scale weather station network dating back to the Victorian era. It also launched lots of weather satellites in the 70s.
