The first six months of 2016 were the hottest ever recorded, NASA announced today, while Arctic sea ice now covers 40% less of the Earth than it did just 30 years ago.
The increase in carbon dioxide has come party from burning fossil fuels, and has surpassed historic highs in the past decades according to NASA.

And we can trust NASA/NOAA, yeah right.
Evaluating The Integrity Of Official Climate Records http://realclimatescience.com/wp-content/uploads/2016/07/Evaluating-The-Integrity-Of-Official-Climate-Records-4.pdf NASA has repeatedly altered their own data, making pre-1980 temperatures cooler doubling 1880-1980 warming by altering data.
https://bobtisdale.wordpress.com/2015/06/04/noaancdcs-new-pause-buster-paper-a-laughable-attempt-to-create-warming-by-adjusting-past-data/ Comments from Georgia Tech Climatologist Dr. Judith Curry. The greatest changes in the new NOAA surface temperature analysis is to the ocean temperatures since 1998. This seems rather ironic, since this is the period where there is the greatest coverage of data with the highest quality of measurements – ARGO buoys and satellites don’t show a warming trend. Nevertheless, the NOAA team finds a substantial increase in the ocean surface temperature anomaly trend since 1998…The global surface temperature datasets are clearly a moving target. So while I’m sure this latest analysis from NOAA will be regarded as politically useful for the Obama administration, I don’t regard it as a particularly useful contribution to our scientific understanding of what is going on.
