As carbon dioxide continues to be released in truly massive quantities by industrial civilization, so too does the greenhouse effect continue to strengthen -- as evidenced by the most recent global temperature figures from NASA.
July 2015 was the hottest July on record (since record-keeping began 125 years ago) according to these recent figures, setting the stage for 2015 to surpass 2014 as the hottest year on record. And by "surpass" here, I mean greatly surpass. This is expected to be aided by the fact that this year is seeing one of the strongest El Niños in around a half a century.
Here's a chart that shows things rather bluntly (via Dr John Abraham):
That certainly is a vivid illustration, is it not? Quite a sharp rise. One that is expected to continue rising as El Niño continues to strengthen throughout most of the remaining months of 2015.
An article in the journal Nature even predicted that the current El Niño could well end up being the strongest on record, once all is said and done -- with a projected peak occurring sometime this winter. If that prediction ends up holding true, then we can expect to see 2016 temperatures surge over 2015 ones pretty significantly -- setting yet another new record for hottest year since record keeping began.
