The first half of the year has already seen some heat extremes: it was the warmest half-year ever recorded for the planet and each month from January to June was the warmest month ever in the modern temperature record. And that record spans back all the way to 1880. THE SUPREME HEAT SEEMS TO BE STICKING AROUND DESPITE THE LESSENING EFFECTS OF EL NIÑO NASA made these high temperature measurements thanks to satellite data and ground-based observation. And the space agency notes that the supreme heat seems to be sticking around despite the lessening effects of El Niño — a period of abnormally high temperatures in the Pacific Ocean that influences weather. "While the El Niño event in the tropical Pacific this winter gave a boost to global temperatures from October onwards, it is the underlying trend which is producing these record numbers," said Gavin Schmidt, the director of NASA’s Goddard Institute for Space Studies. This indicates the extreme temperatures are the result of an overall warming that has taken place over the last couple of decades, thanks to the abundance of heat-trapping gases like carbon dioxide in the atmosphere, NASA argued.
The high temperatures in the first half of 2016 have also correlated with low sea ice coverage in the Arctic. Five out of the first six months of the year set records for having the smallest monthly coverage of Arctic sea ice since satellite observations of the region began in 1979. Now, during the peak summer melt season — when the Arctic ice is melted away by the Sun — the ice coverage is about 40 percent less than it was in the late 1970s and early 1980s, according to NASA. If 2016 does become the hottest year on record, that marks three years in a row that the world’s global temperatures have set records. Previously, 2014 was considered the warmest year in recorded history, but it was eventually beat out by 2015.

I would say that I expected warmer weather to arrive months before it did ... and temperatures haven't really been all that warm so far.
But that's just me. It's a big world out there. Let's see how many people will come along and directly contradict me.
Here are highlights from just the first 10 minutes of the video:
“Eighty years ago this week, the US was experiencing the worst heat wave in the history of the United States, says Heller. All of the Midwest, all of the east coast except up into northern New England, was over 100 degrees.
Same in South Dakota, where temperatures reached an almost unbelievable 120 degrees.

Remember that hullabaloo a few weeks back about how hot it was going to climb in Phoenix? That South Dakota temperature from 1936 was even hotter.
Or look at Omaha. Omaha used to have 110-degree days, Heller points out.
No more. There have been no 110-degree days in Omaha since 1954.

Actually around 1936 it was warmer certainly in the USA with Omaha reaching 110 degrees f and South Dakota an unbelievable 120

Assuming there is a brief cool down around 2020, the next “warm and dry” climatic phase is scheduled to arrive in the early 2030s, probably peaking around 2038. It is expected to produce even hotter and drier weather patterns than we saw during the late 1990s and early 2000s.
But, we should remember, that the Earth’s coldest periods have usually followed excessive warmth. Such was the case when our planet moved from the Medieval Warm Period between 900 and 1300 A.D. to the sudden “Little Ice Age,” which peaked in the 17th Century. Since 2,500 B.C., there have been at least 78 major climate changes worldwide, including two major changes in just the past 40 years.
By the end of this 21st Century, a cool down may occur that could ultimately lead to expanding glaciers worldwide, even in the mid-latitudes. Based on long-term climatic data, these major ice ages have recurred about every 11,500 years. The last extensive ice age was approximately 11,500 years ago, so we may be due again sometime soon. But, only time will tell.
You want earth temps here they are: www.ncdc.noaa.gov...
For what reason is that assumed?
Assuming there is a brief cool down around 2020,
False, and someone does not seem to know the difference between an ice age and a glacial period. But, in any case, in the past no one was pumping prodigious amounts of CO2 into the atmosphere.
Based on long-term climatic data, these major ice ages have recurred about every 11,500 years.
You assume that natural cycles are the only influence on climate.
I assume without putting words in their article for them it has to do with the cyclic nature of warming an cooling the earth goes through.
Judith Curry does not deny that warming is occurring but she does think that the effects of CO2 are overstated. Scientists don't "close their ears", they look at the physics and the data.
This lady points out why so many people close their ears when the subject is brought up.
Yes. Because very large amounts of money are being spent in efforts to maintain the status quo in energy production.
Trust for many right or wrong has been lost.
The Sun's magnetic field (the Sun actually has a conglomeration of magnetic fields, not really a single field like Earth) "reverses" every 11 years and it has no effect on Earth's magnetic field.
What about the reversal of the sun's magnetic field and it's affect on the earth's magnetic field?
