Evidence for man-made global warming has vanished

Where is the real evidence of man-made global warming? Where are the signs? Where are the measurements?

The simple fact is that in spite of what computer models might say, without global warming, there is no man-made global warming.

I am more persuaded by evidence than by climate models which have only demonstrated that they do not work. The man-made global warming hypothesis has a number of crucial assumptions which are all proving to be unproven, lacking evidence or just plain wrong.

  1. Global temperature is increasing, and
  2. Increasing carbon dioxide concentration in the atmosphere is due to man-made effects, and
  3. Increasing CO2 concentration does give measurably increasing global temperature, and
  4. Increasing man-made carbon dioxide emissions does give significant and measurable increases in global temperature.

Every one of these assumptions is suspect and- at best – uncertain.

“Global Warming” has warped to be “Climate Change” so that any slightly unusual weather event can be claimed to be man-made. The hypotheses are never falsifiable. But the bottom line remains that all the change can be put down to man-made emissions which increase the heat trapped on earth, which then cause global temperatures to rise and fuel the “climate changes” observed. But all man-made climate change vanishes without man-made global warming to power it.

The signs of global warming were touted as being ice melting, sea level rising, loss of polar wildlife and sundry other secondary catastrophes. The poster-children of the global warming religion were the loss of polar ice, the corresponding rise of sea levels, disappearing islands, and the extinction of polar bears.

Just consider the real evidence.

Antarctic sea ice cover has reached the highest levels ever measured and has reached record levels for each of the last 3 years

NSIDC: This year’s Antarctic sea ice maximum was 1.54 million square kilometers (595,000 square miles) above the 1981 to 2010 average maximum extent, which is nearly four standard deviations above this average. The 2014 ice extent record is 560,000 square kilometers (216,000 square miles) above the previous record ice extent set on October 1, 2013. Each of the last three years (2012, 2013, and 2014) has set new record highs for extent in the Antarctic.

Arctic sea ice cover has recovered from the low of 2012 and is now within the 2SD band of the 1981-2010 average. It is up 84% from 2012 and the trend is upwards.

The trend for Arctic ice is upwards

Global sea ice cover is unchanged and shows no discernible trend since 1979.

Global temperatures have not risen for 18 years. In recent years there may even be a cooling trend.

Forbes:Remote Sensing Systems(RSS) also compiles data from the satellite instruments, though RSS measures a slightly different range of the lower atmosphere. RSS reports a similar temperature history,available here. In the RSS compilation, we see not just a recent temperature plateau, but actual cooling. Again, the pace of warming throughout the entirety of the record is approximately 1 degree Celsius per century.

In the last 18 years man made carbon emissions have increased by about 70%. Over the same period carbon dioxide concentration in the atmosphere has risen by about 10% and global temperatures have not risen at all. On this data there is no correlation between global temperature and carbon dioxide concentration let alone carbon dioxide emissions.

Polar bear numbers are higher than for 50 years and walrus numbers are very high as well.

Sea level increases are no higher than the long term rise due to coming out of a glacial age. A rise of 2 inches by 2050 is on the cards.

Where is the evidence of man-made global warming?
