Our present-day NOT abrupt climate change.

or how I learned that the alarmists are the true science deniers.

--> Mountain Avens aka Dryas Octopetala

This is a Mountain Avens aka Dryas Octopetala. Dryas from the Greek for Oak drus and octopatala or eight petals. (Mountain Avens is given some measure of protection in Northern Ireland under the Wildlife (NI) Order, 1985. LINK)

Dryas Octopetala flourishes in cold conditions, As NOAA’s NCDC write:
The Younger Dryas is one of the most well-known examples of abrupt change. About 14,500 years ago, Earth's climate began to shift from a cold glacial world to a warmer interglacial state. Partway through this transition, temperatures in the Northern Hemisphere suddenly returned to near-glacial conditions. This near-glacial period is called the Younger Dryas, named after a flower (Dryas octopetala) that grows in cold conditions and that became common in Europe during this time. The end of the Younger Dryas, about 11,500 years ago, was particularly abrupt. In Greenland, temperatures rose 10°C (18°F) in a decade (Alley 2000(bold added)
As the world slid into and out of the last ice age, the general cooling and warming trends were punctuated by abrupt changes. Climate shifts up to half as large as the entire difference between ice age and modern conditions occurred over hemispheric or broader regions in mere years to decades. Such abrupt changes have been absent during the few key millennia when agriculture and industry have arisen. The speed, size, and extent of these abrupt changes required a reappraisal of climate stability. (bold added)

The Cool Period known as the Younger Dryas was from ~12900-11,500BP. At the beginning of the period, temperatures dropped around 8ºC in less than 100 years and possibly only a decade.


On WUWT, Don Easterbrook writes:
The Younger Dryas is the longest and coldest of several very abrupt climatic changes that took place near the end of the late Pleistocene. Among these abrupt changes in climate were: 

  1.  - sudden global warming 14,500 years ago (Fig. 1) that sent the immense Pleistocene ice sheets into rapid retreat, 
  2. - several episodes of climatic warming and cooling between ~14,400 and 12,800 years ago, 
  3. - sudden cooling 12,800 years ago at the beginning of the Younger Dryas, and 
  4.  ~11,500 years ago, abrupt climatic warming of up to 10º C in just a few decades. (Link WUWT) (bold added)

Note - abrupt climatic warming of up to 10º C in just a few decades.

Professor Ian Plimer says that the warming change was even greater:
After this 1300 year period of intense cold, global temperatures rose very rapidly by about 12°C marking the end of the Younger Dryas cold period and the end of the latest glaciation. (How to get expelled from school = Connor Court )

Ten Degrees? 12 degrees? What really matters is that there was rapid warming.

Now that is climate change? What caused it? Obviously, it was Fred Flintstone and Barney Rubble screaming around bedrock in their SUV.

The Earth has warmed since the Little Ice Age. NASA's Earth Observatory has told us (Link)
But the global temperature mainly depends on how much energy the planet receives from the Sun and how much it radiates back into space—quantities that change very little. ........In the past, a one- to two-degree drop was all it took to plunge the Earth into the Little Ice Age.

And NASA also tells us:
According to an ongoing temperature analysis conducted by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by about 0.8° Celsius (1.4° Fahrenheit) since 1880.
So there you have it, straight from the's mouth; less than a rise of one dgreee since the frightful cold of the little ice age. Saved the world from severe cold. The warming has been beneficial and, definitely not abrupt.

Why are the alarmists, those deniers of true science, trying to scare us?

Earth Day should Celebrate 
“Engines and Electricity”.

Most chapters of human history are defined by the tools and machines that were used.

In the Stone Age, the first tools were “green tools” – digging sticks, spears, boomerangs, bows and arrows made of wood; and axes, clubs, knives and grinders made of stone. These were all powered by human energy.

Then humans learned how to control fire for warmth, cooking, warfare and hunting.

Another clever person invented the wheel and we harnessed animal power using donkeys, horses, mules and oxen, and made better tools like bridles, saddles and yokes from wood, fibre and leather.

All of these tools made hunting, gathering and trade easier and more reliable.

Then wooden ploughs revolutionised the cultivation of wild grasses for food for animals and humans. Farming started.

Trade and exchange were made easier with money using rare commodities like gold, silver, gems and shells.

Tool-making made a huge advance in the Bronze Age with the discovery of how to extract metals like copper, lead, zinc and tin from natural ores using charcoal. Brass, bronze and pewter made many useful tools. These were then replaced with better tools when man discovered how to smelt iron and make steel.

Then along came the game-changers – engines and electricity.

The steam engine, running on wood and then on coal or oil, revolutionised life with steam-driven pumps, traction engines and locomotives releasing millions of draught animals from transport duty.

Then came electricity when steam engines were used to drive generators. All the windmills, coaches, sailing ships, lamps, stoves and dryers powered by green energy (wind, water, wood, animal energy, whale oil and beeswax) became obsolete.

Mankind made another leap forward with the invention of internal combustion engines using petroleum liquids and gases for fuel.

An even bigger leap was the harnessing of nuclear power to produce almost unlimited clean energy from controlled reactions using tiny amounts of fuel.

Nothing in life is without risk, and every tool or engine can be misused. On balance, however, tools, engines and electricity have allowed humans to live better from less land and natural resources per person than ever before. Societies with an abundance of capital equipment are richer, have lower population growth and have the leisure and resources to provide far more environmental protection.

Therefore we should spend “Earth Day” celebrating “Engines and Electricity”.
