Month of July was warmest on record, 2015 headed for warmest year so far, says NASA
When all of the warmest years in a record that goes back hundreds of years start to cluster up in the past 10-15 years, something that you shouldn't ignore is going on. The world is heating up, and the latest data from the US and Japanese agencies adds another boulder to the mountain of evidence for global warming. The independent work by both NASA and Japan Meteorological Agency show that July 2015 was the warmest month on record, and the chances are good - especially because of the strong El Niño - that 2015 as a whole will end up being the hottest year on record too.
The graphs above show the month of July in the top left corner, the past 3 months in the top right, the past 12 months in the bottom left, and temperatures since 1880 in the bottom right.
But as you can see on the maps, there are regional differences. But what matters is the global temperature. You could have a whole country that has the coldest year on record while the rest of the world is burning up...

Most of the world has obviously been warmer than average, but a good deal of regional variation is evident — especially blobs of coolness over North America and the North Atlantic. So for many of us in the United States, it hasn’t seemed so bad this summer. But look at that angry red and rust colored splotch over Europe in July. And the orange and red tones across most of the rest of the world for May through July.
Here is a chart from Japan's Meteorological Agency also showing a worrying uptrend:
Mashable puts it very well:
It's been a cruel, cruel summer for millions of people across the Northern Hemisphere. Extreme heat has been blamed for thousands of deaths from India to Egypt, on northward into Europe and west to the Pacific Northwest cities of Seattle and Portland. Even Japan and Hong Kong have set all-time high temperature records and passed historical heat wave markers.
The most recent heat has occurred in parts of Europe, the Middle East and East Asia. On Aug. 7, for example, Berlin hit 102 degrees Fahrenheit, or 38.9 degrees Celsius, breaking its all-time hottest temperature record of 101.5 degrees Fahrenheit, or 38.6 degrees Celsius. [...] Temperatures have reached a staggering 114 degrees Fahrenheit, or about 46 degrees Celsius, in southern Egypt, which is unusual for that region. At least 40 people have died since Sunday, according to the AP, including patients in a psychiatric hospital.
