The First Truth: Global warming is a reality

In the past fifty years, average temperatures have doubled compared with the average figure for the past one hundred years. The past ten-year period has been the hottest on record.

Scientific observations differ fundamentally from a layman’s day-to-day ones, of the coffee-bar kind. That fact that we think it’s getting hotter by the day in our particular neck of the woods isn’t conclusive proof of the existence of climate change. And vice versa, winters with snowfalls and cold spells aren’t enough to show that climate change doesn’t exist. Scientists assure us that temperatures will rise exponentially in the long term. In the past fifty years, average temperatures have doubled compared with the average figure for the past one hundred years. The past ten-year period has been the hottest on record. Eighteen out of the past twenty years have been the hottest-ever. Temperatures have been recorded since 1850, and the increasingly more comprehensive information they provide just go to strengthen certainty: the world’s most-renowned climate research centers all agree that there is a clear and undeniable trend towards global warming (USA: NOAA 2011, NASA 2011; UK: UK-Met Office 2011; Japan: JMA 2011). Moreover, the average temperature increase is not the same in all parts of the planet: changes are more extreme in Northern parts of the globe.Truth on Climate Change I

Global warming is not a future event: it’s already here. The sea level is on the rise (an average 2.5 mm/year between 1992 and 2001), the acidity levels of the oceans are increasing (30% up since the Industrial Revolution), glaciers are melting (80.7m per year in the past ten years) and so too are the Polar ice-caps (35% in the Arctic since 1992). Studies carried out on thousands of species show extraordinary changes in migration patterns in terms of both altitude and latitude. One particular study involving 1,700 species registered shifts of 40km towards the North Pole and 6 meters per decade in Alpine regions during the second half of the 20th century.

Something is causing the planet to get warmer: there’s no room for doubt for either the informed but less demanding layman or the seasoned scientist.

The scientific community is more than sure and, as an example, we’re giving you this link to an article published recently in the Wall Street Journal, signed by more than 40 top-level researchers, stating that “Research shows that more than 97% of scientists actively publishing in the field agree that climate change is real and human caused”.

This is the first truth of the "ten truths of climate change"
