The world has continued to get warmer since the Little Ice Age (about 1400-1700 AD), the period when they skated on the Thames River, and will likely continue to warm for another 200-300 years, in stops and starts, towards a max temp roughly matching the Medieval Warm Period when Icelandic Vikings raised cattle, sheep and goats in grasslands on Greenland’s south western coast.

U.N.’s Intergovernmental Panel on Climate Change (IPCC) who do no original research of their own, but instead periodically assess and sumarise published scientific literature on climate change, have done their best to exaggerate the rate of warming by the way they produce their charts.

Lying with Charts  from Abhinan’s Tech and Analytics.  Global Warming is a serious yet controversial enough topic without bringing in bad data. While the chart below shows the last decade, 2001-2010 as the hottest, they use a broken Y-axis that begins at 13.4°C instead of starting at zero. The charts below left do not hide this fact, and you can see that the chart’s Y-axis starts at 13.4°C, but the most visually prominent piece in the graph is, well, the graphs! It screams the message that global temperatures are going off the charts –time to panic?.

Above same temperatures but drawn correctly with a Zero Y axis

Dismissing the recent 18 years or so of relatively flat global temperatures, the IPCC have stated that: “It is extremely likely that human influence on climate caused more than half of the observed increase in global average surface temperatures from 1951 to 2010″. In that period average temperatures rose by 0.55 C which means that man likely contributed approximately 0.27 C in the 59 years or at a rate of 0.55 C per century…. no big deal!

World temperatures readings from 1945 through to 1976 did show a slight cooling but were mostly stable in this period. In 1971 an influential group of scientists wrote to the president of the Unite States warning that that there was enough evidence to show that the beginning of an ice age was at hand and wanted funding to study on measures of how to deal with it but when temperatures began to rise slightly they were forced to abandon the theory and were to later to seek funding on how to combat global warming when temperatures began to rise slightly.

In 1972, two scientists – George J. Kukla (of the Lamont-Doherty Geological Observatory) and R. K. Matthews (Chairman, Dept of Geological Sciences, Brown University) – wrote a letter to President Nixon warning of the possibility of a new ice age:

Over the last century the forest cover around the globe has been greatly compromised, leaving the green cover down to an all time low of about 30 per cent.  According to the United Nations Food and Agriculture Organization (FAO), an estimated 18 million acres (7.3 million hectares) of forest are lost each year. The Paris accord did not include any firm policy on deforestation.
