I have written many posts on climate change and my last major work was titled, Rapid Warming is Here — May 22, 2015.
Now, for the first time since the development of human civilization, northern hemispheric temperatures have spiked above a temperature level that is 2C above the average from pre-industrial times (defined as the average surface temperature between 1861 and 1880).
I have consistently worked here to show the development of climate sciences, their inherent conservatisms and the likely consequences of an “all of the above” strategy as promoted by Pres Obama and now, Hillary Clinton. I have posted here for many years.
I have researched global warming and its existential threat to humanity for many more

Our Hemisphere’s Temperature Just Reached a Terrifying Milestone
Update, March 3, 2016: Since this post was originally published, the heat wave has continued. As of Thursday morning, it appears that average temperatures across the Northern Hemisphere have breached the 2 degrees Celsius above “normal” mark for the first time in recorded history, and likely the first time since human civilization began thousands of years ago.* That mark has long been held (somewhat arbitrarily) as the point above which climate change may begin to become "dangerous" to humanity. It's now arrived—though very briefly—much more quickly than anticipated. This is a milestone moment for our species. Climate change deserves our greatest possible attention.
This spike has been reproduced in a separate dataset, so there remains high confidence that the 2-degree level was breached.
If you have any questions about this or any of my other work, please let me know. I do not intend to post or spend much time here anymore.
