We Are Roasting

“This animation shows annual temperatures each year since 1880 compared to the twentieth-century average, ending with record-warm 2016. Because of global warming due to increasing greenhouse gases, the maps from the early years in the animation are dominated by shades of blue, indicating temperatures were up to 3°C (5.4°F) cooler than the twentieth-century average. Recent years’ maps are dominated by shades of red.”

A wise man once wrote, “I often say that when you can measure what your speaking about, you know something about it; but when you cannot express it in numbers, your knowledge if of a meagre and unsatisfactory kind;”. Amen. The global warming deniers have an unsatisfactory knowledge. Here is the fact, Earth is several degrees warmer today than in the last century. Yes, 2016 is the warmest year recorded in recent times, even beating out 2015… Take a hint. The temperature of Earth rose sharply in step with consumption of coal/oil/natural gas. The Arctic is being ruined for animals adapted for its extremes. I’m getting crazy mild winters in my old age compared to when I was a kid. I guess it’s someone else’s problem soon but lets not make it worse for our kids, eh?

I am a retired teacher in Canada. I taught in the subject areas where I have worked for almost forty years: maths, physics, chemistry and computers. I love hunting, fishing, picking berries and mushrooms, too.

    “I understand exponential growth” — that is because you taught science! Unfortunately, the vast majority of the public just don’t get it. As to the mechanism in ice shelf and glacier collapse it is a bit more complicated than that, but yes there are some very strong feedback mechanisms. Links in the article links will supply the full peer refereed details.

  2. ram wrote, “These type of geophysical collapses accelerate exponentially.”

    I understand exponential growth. It requires some positive feedback. I suppose less ice means less reflected sunlight/cool water so the rate of heating increases… That might explain our crazy mild winter this year. Despite a bit of cold and a bit of snow, we are having a heat wave in January. It’s not unusual to have a day or two warm but this is ridiculous, weeks of it. We had one day of -35C and now two weeks of near 0C high temperatures. It’s melting here tonight.

    That sea level rise may come sooner than most people think. The mathematics of the Greenland and Antarctic glaciers sliding into the oceans are the same as the “stope stability” problem of geotechnical engineering (mining engineering).

    These type of geophysical collapses accelerate exponentially. They go from barely measurable to catastrophic rather quickly. Fundamentally, “The greatest shortcoming of the human race is our inability to understand the exponential function.”

  4. ram wrote, “It is really going to take the 5-9 meter sea level rise due to collapsing Greenland and Antarctic glaciers to wake people up.”

    Well, the current crew in Washington won’t wake up in the next four years or so. They are under anaesthesia. As long as they can afford multi-million dollar homes “somewhere else” with air-conditioning, the rest of us can go to Hell. Selling oil and real estate is all they care about.

    I am also amazed how some people, particularly “fundamentalist Christians” can pretend global warming is not happening. Where I live in the lower Blue Mountains of NSW Australia in my grandparents time used to get significant snowfalls. Now we don’t even get frosts. Growing palms, pineapples, gingers, turmeric, bananas, and other tropical fruits in the garden.

    Two days ago we had record high temperatures. I spent most of the day at a Fire Control Centre. Fortunately, the Blue Mountains avoided catastrophe. Some other towns in other districts were not so fortunate. Two days later, the mass media just ignores that entire communities were just erased by fires and then by severe storms. It is really going to take the 5-9 meter sea level rise due to collapsing Greenland and Antarctic glaciers to wake people up.

  6. dougman wrote a bunch of numbers with no evidence to back them up like this one: “In 1990, it was estimated that volcanoes released 100 million tons to the atmosphere. In 2000, it was 200 million tons. This past Feb.,2016, it was 600 million tons.”

    How much CO2 does burning 96 million barrels of oil per day produce? USA alone uses about 19 million barrels of oil per day. A barrel burnt delivers about 0.43 tons of CO2 so 96 million comes to 41 million tons per day, overtaking what the volcanoes do in 15 days. It’s insane to burn that much oil. It’s pollution.

  7. dougman says:

    “The temperature of Earth rose sharply in step with consumption of coal/oil/natural gas.”

    That being the alleged case, can you explain the retreat of glaciers some 12000 years ago? No human consumed coal/oil/natural gas then.

    Also, during the Paleocene-Eocene geologic record, thermal maximum was measured to have a average temperature as high as 23°C (73°F), which is a far cry from today’s average temperature at just under 15°C (60°F).

    Geologists and paleontologists think that during much of the Paleocene and early Eocene, the poles were free of ice caps, and palm trees and crocodiles lived above the Arctic Circle, while much of the continental United States had a sub-tropical environment.

    Too many are fussing over the CO2 quantities and missing the larger picture. We currently live in an ongoing Ice Age inter-glacial, commonly called the Holocene. And this won’t change so long as those two little white things at the poles persist and we have not yet plunged back into another glacial period. But, oops! We’re currently overdue for a return to glacial conditions, based on average inter-glacial lengths of the current Ice Age.

    The fact that the UN, NASA, Al Gore and others are shouting “earth’s fever” while we’re experiencing a minor thaw in an Ice Age, shows just how psychopathic some people have become on this topic. Most of Earth’s history has been something like 10C warmer than today and with 1600 ppm CO2 (4x current levels). No runaway greenhouse effect. Why? Because the positive feedback’s are cancelled out by the negative feedback’s of evaporative cooling and cloud cover reflectivity.

    In 1990, it was estimated that volcanoes released 100 million tons to the atmosphere. In 2000, it was 200 million tons. This past Feb.,2016, it was 600 million tons. I think you found your hockey-stick Pogsey.

    I have three problems with this warming bullshit.

    First, you people like Pogsey assume that global warming is bad. That’s insane. Global warming is what made civilization possible 12,000 years ago.

    Second, Pogsey assume’s that CO2 is bad. But with the fact that global warming is actually good, what does CO2 do? It feeds the plants! The average CO2 level for the last 600 Million years has been 1600 ppm (4x today’s “scary” levels), with millions-of-year periods with levels at far higher levels. Plants were so starved for CO2 about 30 Million years ago, as levels were plummeting down to 800 ppm (2x today’s levels), that they evolved C4 species.

    Third, Pogsey enjoy’s being under the delusion that CO2 is the driving force of modern warming. CO2 has not caused the steady climb in temperatures of the last 400 years. If you look at the climate record, we’ve had several peaks, each spaced about 1000 years apart. Warm periods included: the Minoan, Roman, Medieval, and now Modern.

    The cycles have clearly shown that we would’ve had a warm period with or without humans and their SUVs. The fact that the biggest burst of human CO2 production accompanied a 30-year stretch of global cooling should disabuse anyone of the silly notion that CO2 is driving temperature.

    My advice, don’t be a Pogsey.
