Yahoo and HuffPo call this "normal" winter weather: It's not

Here. But hot summer temperatures evoke global warming headlines. 

The mean monthly lowest minimum temperature in Grand Rapids, Michigan in Decembers is +4 F. With today and tomorrow to go, we're already at - 12 F, the third coldest on record.

Average temperature in December 2017 so far ranks 32nd coldest out of 126 Decembers, the 75th percentile. Normal would be the 50th percentile. So it's definitely colder than normal, while not absolutely record setting.

Climate shmimate. These idiots can't predict bupkis three days out let alone from month to month and century to century. All year long average temperature has been running warm, until December ruined their little global warming narrative.

Bwaaaaaaahahahahaha.

Grand Rapids, Michigan, climate update for September 2017

Max Temp: Actual 96, Mean 89
Min Temp: Actual 41, Mean 37
Av Temp:   Actual 66.5, Mean 62.7, YTD Actual 53.9, YTD Mean 51.1

CDD:         Actual 136, Mean 75, YTD Actual 708, YTD Mean 685

In short year to date we are slightly warmer and dryer than the mean.

Average temperature is running 5.5% ahead of mean and cooling degree days about 3.4% ahead of mean. The rain deficit is running about 4.9% behind the mean. For average temperature year to date, compare some of the hotter years 2012 at 56.4, 1931 at 54.2 and 1921 also at 56.4, the average of which is 55.7. We are still 3.2% cooler than that in 2017.

Last season's average ONI value was -0.266, the lingering effects of the five month long Weak La Nina, indicating a very slightly cool ocean in the tropical Pacific over the last year. The preliminary read of the first value in the new season is -0.1.

Despite the heat wave we experienced in September, I still used 8% fewer kWh this September than last and stayed comfortably cool.

International Howler of the Day: Britain voted for Brexit yet Theresa May criticizes those who fail to respect international agreements

Having it every which way to Sunday she was.

From the story here:

Leaders who fail to respect international agreements risk jeopardising faith in institutions, she warned. Delivering a thinly-veiled rebuke to the US President, she said climate change “is depleting and degrading the planet we leave to our children”. And the PM hit out at countries which try to stifle global trade, after Mr Trump's “America first” inauguration speech in January. She warned against moves which “undermine support for the forces of liberalism and free trade that have done so much to propel global growth”. ... But Mrs May threatened to split cash from UN programmes that fail to produce results.

Grand Rapids, Michigan, climate update for July 2017

Mean average temperature was 72.5 degrees F in July 2017 in Grand Rapids, Michigan. The mean is 72.2. The average to date is 50.0. The mean to date is 46.7.

The lowest minimum temperature was 53. The mean is 49.

The highest maximum temperature was 90. The mean is 94. July is the warmest month of the year by average temperature (above), so it's not going to be a very hot summer since it's all downhill from here.

Precipitation was 1.12 inches. The mean is 3.13.

Cooling degree days came to 240, which is the mean. The total to date is 432. The mean to date is 422.

I have corrected my climate update for June 2017. Either I or NWS reported incorrect figures for lowest minimum temperatures and for cooling degree days, not sure which. I noticed the discrepancy today and fixed it. May 2017 checks out OK.

The three month Oceanic Nino Index value has averaged -0.32 over the last eleven months, climbing to +0.5 in the last measurement period in April-May-June after a weak cooling event in the Pacific lasting five months.

NOAA's Climate at a Glance tool deliberately leaves out data going back to 1896 to misrepresent the Grand Rapids, MI, temperature trend

You can ask the Climate at a Glance tool for the data going back to 1896, but it won't give it to you:



















But the data exists for Grand Rapids at the National Weather Service, from which I made this graph:

Trump correctly called the Paris Climate Accord a scheme to redistribute American wealth abroad


We have among the most abundant energy reserves in the planet, sufficient to lift millions of America's poorest workers out of poverty. Yet under this agreement, we are effectively putting these reserves under lock and key, taking away the great wealth of our nation, great wealth, phenomenal wealth. Not so long ago we had no idea we had such wealth. And leaving millions and millions of families trapped in poverty and joblessness. The agreement is a massive redistribution of United States wealth to other countries. ... 

Beyond the severe energy restrictions inflicted by the Paris accord, it includes yet another scheme to redistribute wealth out of the United States through the so-called "green climate fund" -- nice name -- which calls for developed countries to send $100 billion to developing countries all on top of America's existing and massive foreign aid payments.
