Renowned Carmelite climate scientist, Fr Eduardo Scarel, looks at the state of the earth's climate over the last 4 years - the 4 warmest ever recorded. He explains the causes of global warming and the effect on temperatures, extreme weather events, ice shrinkage and the rise of CO2 emissions.
"The next few years are crucial", he says. "We are the last generation that could and should act to avoid crossing crucial turning points and avoid irreversible damage to our common home, the earth, the abode of humanity and the rest of God's creatures."
