James Hansen: Why I Must Speak Out Against Climate Change
Kicking the Hornet’s Nest
For decades now Dr. James Hansen has warning people and doing his best to fight the onset of planetary climate change. In this TED Talk he describes his journey from climatologist at NASA, to environmental activist.
Early & Repeated Warnings
Dr. Hansen first testified before the US Congress back in the 80s, informing them of the threat to the planet caused by increasing greenhouse gas (GHG) emissions. Our reliance on fossil fuels to power human civilization has been generating vast and increasing amounts of CO2 in the earth’s atmosphere.
As a scientist who has studied in depth the effects of rising GHGs, he was understandably alarmed by what he observed from the earth’s climate data. It was (and is) evident that humans were impacting the earth’s climate, and it was having an increasingly devastating effect (see Running Low On Time).
Unfortunately, his warnings are still not being met with the urgency they deserve. The fossil fuel industry and oil lobbyist have a profound effect on both government and the media (The Guardian). It certainly has been an incredible struggle for Dr. Hansen to get man-made climate change the attention it seriously requires. Thankfully, he remains motivated to continue his work, and committed to sharing the message.
