20 New Papers: Higher CO2, Global Warming Increase Crop Yields, Green The Earth, Reduce Weather Extremes, Extend Human Life

Back in the early 1970s, when there was a scientific consensus that the Earth was cooling and that cooling was not good for the biosphere, scientists were ranking human-generated pollutants in terms of their potential to do harm to the planet. At that time, CO2 was regarded as “the least objectionable or only beneficial addition to the atmosphere from industrial sources.”   ......

Climate Clash: Aussie Senator Malcolm Roberts Owns TV Physicist Brian Cox

Brian Cox attempted to embarrass Roberts with a copy an unnamed “Global Land Ocean Temperature” graph. Unfortunately for Cox, Roberts has expert knowledge of climate datasets. Roberts challenged the validity of the graph on the basis that it showed 1998 as being significantly cooler than 2015/16, and challenged Cox to provide details of the dataset, and the original unadjusted temperature records.
In my opinion Brian Cox came across as arrogant and unprepared – he obviously thought he would effortlessly trample Roberts with the help of some half baked assertions, an appeal to his authority as a “Physicist”, and a sympathetic audience. I doubt Cox will make the same mistake twice."

Aussie Chief Scientist: “We have [climate] models to try to predict what that will be and that’s difficult”

One Nation Federal Senator and hardcore climate skeptic Malcolm Roberts, who recently skewered TV Physicist Brian Cox on national TV, has demanded the Australian Chief Scientist provide evidence that humans cause climate change. The response so far is less than confident.   ......
I suspect this challenge is going to get very uncomfortable for Australia’s chief scientist.
Malcolm Roberts, a qualified and highly experienced mining engineer, is one of the few elected Australian politicians with the skill and meticulous attention to detail required to dissect anything the bureaucrats who run government science organisations can throw at him.
His demand for proof that humans cause warming has struck at the weak point of the entire AGW scare campaign – because there isn’t any proof available to provide. Just a load of conjecture, based on a weak set of models which don’t work very well.
Most people agree that adding CO2, considered in isolation, should produce a mild warming effect. But the entire climate scare campaign is based on models which assume that the initial warming effect from anthropogenic CO2 is dramatically amplified by feedback, by climatic responses to the initial warming.
The problem is there is no evidence this amplification is actually occurring – models which assume amplification perform woefully when compared to real world observations, far worse than models which assume no amplification, or very little amplification."

Global Warming be Damned: Record Corn, Soybeans, Wheat

Roy W. Spencer, Ph. D.

But droughts have always occurred. The question is: Are they getting worse? And, has modest warming had any effects on grain yields?   ......
How can this be?"


The number of U.S. wildfires for the period 1984 to 1999 is essentially unchanged from the number of  U.S. wildfires for the period 2000 –2015. Additionally the latest year to date wildfire data ( for the last ten years shows absolutely no consistent upward trend whatsoever in either burned acres or number of U.S. wildfires which have occurred. The new wildfire study also fails to address that U.S. drought data does not support claims of increased nationwide droughts as driving increased number of wildfires. "

Extreme Rainfall Trends In Australia

Paul Homewood
To sum up:
1) Rainfall is not becoming more extreme.
2) Dry spells are becoming less common.


The “Ice-Free Arctic” Big Lie

Real Science
Every year we are told by Nobel Prize winners, climate scientists and environmental activists that the Arctic will be ice-free that year. They are flat-earthers.
It is impossible for the Arctic to be ice-free under current climate conditions, because the Earth is round. Because of the high albedo of clouds and ice and the low angle of the sun, north of 80N they don’t get enough solar energy to melt that much ice. The prevailing winds also jam the ice up against the Canadian Coast, and make it very thick. Climate scientists have been making idiotic predictions about an ice-free Arctic for generations. They have no idea what they are talking about. ....."
