Climate change sceptic Richard Lindzen is challenged on his view that concern about global warming is alarmist nonsense.
Many believe that climate change is now a fact of life. It seems that sea levels are rising, weather patterns are changing, and glaciers are melting.
Some scientists say the earth’s climate changes constantly and naturally, but the vast majority of them believe the current rise in global temperature is man-made, and could be catastrophic for the planet.
But is all this but a case of extreme ‘climate alarmism’?
