No doubt about it. The Earth’s climate is cooling!

One of the most prescient indicators clearly shows it, namely the Danish Meteorological Institute’s daily mean temperatures for the Arctic area north of the 80th northern parallel. They have been measured for over 50 years which shows a long-term average of 90 days with the air temperature above freezing.

The Year 2013

The year 2013 has seen a dramatic departure from that routine. In 2013, the summer (above freezing temperatures) lasted for only 45 days, one half of the average number of days. Not only did the frost-free days start much later than on average this year, they also ended much earlier, see the figure below. In fact, the frost-free period seen this year was significantly shorter than in other year since 1958, when the recordings began.

Fig. Observed temperatures in the Arctic (latitude above…

EF-5 Tornadoes On The Decrease

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

 

In my post yesterday, Are Tornadoes Getting Stronger?, I included a graph of EF-5 tornadoes.

The years when there were no EF-5’s I had left blank on my spreadsheet, rather than entering zeros. I am advised by statistical experts that this affects the trend line that is automatically worked out by the program.

So, I have now corrected the graph, and this is shown below.

The trend now shows a decrease since 1970. I would, however, add the same warning as I did yesterday – the number of EF-5’s is so small, and the distribution is so wide, that only limited conclusions can be drawn.

The 1965 Platte River Flood

Real Climate Science

About once every 20 years Colorado has rainfall and flooding more severe than the current 1000 year biblical flood. One of these events occurred in 1965 and killed 21 people.

Some of the largest rain totals were observed in the southeast potion of the state. Many of these rainfall amounts were unprecedented. The 14 hour 15.5 inch rainfall south-southeast of Lamar was about three times the 100-year 12-hour rainfall.

The Ten Deadliest Tornadoes

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

 

While we are on the topic of tornadoes, I thought we’d have a look at the ten deadliest ones, as listed by NOAA.

It is of course difficult to compare different eras. Nowadays, we have better warning systems and stronger buildings, but, on the other hand, many areas are more populated now.

Nevertheless, the list gives a useful historical insight.

The Tri-State tornado of 1925 remains top of the list. One of the main reasons for this was that it was on the ground for so long. Altogether, it covered 219 miles, in 3 1/2 hours.

For further information on the Tri-State, NOAA have a page devoted to it here.

Fox News Extends History Back To 1997

Real Climate Science

You would have to go all the way back 16 years to find a more intense rainfall event along the Front Range.

IT’S NOT OVER:Colorado braces for more rain, floods

All the way back to 1997

this disaster is all too familiar for those who have lived in Northern Colorado. This situation prompts us to pause and reflect on the 1976 Big Thompson Flood, which impacted the entire canyon from Estes Park on down, as well as the 1997 Spring Creek Flood in Fort Collins. The Big Thompson Flood claimed 143 lives; five women died in the Fort Collins flood.

The state of climate science: ‘fluxed up’

Watts Up With That?

Science not settled, still in a state of flux – IPCC AR5 in disarray. It is looking like my single word quote in Rolling Stone “stillborn”, will be accurate.

The title is my twist on what Dr. Judith Curry said in an email to David Rose in his latest article about the upcoming IPCC AR5 report:

Last night Professor Judith Curry, head of climate science at Georgia Institute of Technology in Atlanta, said the leaked summary showed that ‘the science is clearly not settled, and  is in a state of flux’.

She goes on to say:

Understanding Colorado Flooding

Real Climate Science

The Poudre River in Fort Collins drains more than 500 square miles of mountains and empties through a narrow canyon.

The Big Thompson River in Loveland drains more than 500 square miles of mountains and empties through a narrow canyon.

ScreenHunter_572 Sep. 14 10.30

The St. Vrain River, Lefthand Creek and Boulder Creek drain more than 500 square miles of mountains and empty through narrow canyons.

ScreenHunter_571 Sep. 14 10.29

Upslope winds force humid air from the plains up into the mountains. The air expands, cools and drops below its dew point. Rain falls and floods occur.

In 1976, the Big Thompson drainage received 14 inches of rain in four hours and produced one of America’s most deadly floods. This week’s rains have been nowhere near that intense.

In 1997, Spring Creek in Fort Collins received 10 inches of rain in four hours, and produced a flood with killed five people. Again, that rainfall was much more intense than this…
