Our brains are wired to ignore climate change, says George Marshall

Two degrees is the target for a global agreement in Paris... having global warming not rise above that threshold. 

As of now, global temperatures are nearly one degree Celsius higher than before the Industrial Revolution.

Seven of the 10 warmest months on record were in 2015. 

Thirteen of the 15 warmest years on record have come since the year 2000.

People are feeling the heat the world over. Stanley Ijeoma runs a corporate climate change consult agency in Abuja, Nigeria.

"The temperatures are frying temperatures. . You get easily dehydrated these days. The sun is very hot. Everybody's complaining. You know, the farmers are complaining that their rainfall pattern has destructed the farming season... There's a lot of uncertainty in trying to predict rainfall. So it's really what we see here every day in Abuja."- Stanley Ijeoma

Two degrees could decide our fate ... And yet in February of this year, Oklahoma Senator James Inhofe stood in the Senate and using a snowball as a prop to disprove climate change. 

In case we have forgotten because we keep hearing that 2014 is the warmest year on record I ask the chair...do you know what this is?  It's a snowball and that is from just outside here. So it is very, very cold out. Very unseasonable, so Mr. President catch this...- Oklahoma Senator James Inhofe 

While environmentalists and scientists shook their heads, plenty of other people were nodding along at what the Senator said.

Because, there are plenty of people who remain stubbornly resistant to believing climate change even exists.
