The UN plan to address Climate Change is for the world to get to zero carbon emission by 2100 and keep global average temperature rise below 2 degrees C from the preindustrial era. This means that the carbon concentration needs to be kept below 450 ppm; we are currently at 400 ppm.
However, there is a belief by some very influential climate activists that say we are already past the safe limit and need to go back to 350 ppm. The 350 target was determined by perhaps the most famous climate scientist, James Hansen.
In our next Zoom-In meeting we will discuss climate science. We will start by viewing James Hansen's TED Talk.

Here are the links to the other videos that were shown at our meeting:
1) This video explains why cold winters are becoming more common with climate change.

ReplyDeleteHere is article on the future of Tom Steyer's NextGen Climate PAC.
ReplyDeleteWith this November's snow storms, we now have a pattern of severe winters. Does this disprove climate change? Actually no. This video explains why extreme winters are expected with global warming.
ReplyDeleteAs you may recall from our last meeting, Obama hinted at a climate deal with China during his speech at the UN Climate Summit. Well now there is a deal just in time for COP20 in Lima.
ReplyDeleteHERE is a response to the China Climate deal by Bill McKibben, the founder of 350.org.
