Dr David Evans: Global Warming is Manmade?

Record leap in carbon dioxide seen in 2015

http://phys.org/news/2016-03-carbon-dioxide.html

Not enough data, right?
Truthers?


The level of carbon dioxide in the atmosphere increased at a record pace last year, US government scientists reported, raising new concern about one of the top greenhouse gases and the effects of global warming.

The measurement came from the National Oceanic and Atmospheric Administration's Mauna Loa Observatory in Hawaii.
"The annual growth rate of atmospheric carbon dioxide... jumped by 3.05 parts per million during 2015, the largest year-to-year increase in 56 years of research," said a NOAA statement.
Last year also marked the fourth consecutive year that CO2 grew more than two parts per million.
As of February, the average global atmospheric CO2 level was 402.59 parts per million. This is a significant rise over pre-industrial times. Prior to 1800, atmospheric CO2 averaged about 280 ppm.
"Carbon dioxide levels are increasing faster than they have in hundreds of thousands of years," said Pieter Tans, lead scientist of NOAA's Global Greenhouse Gas Reference Network.
"It's explosive compared to natural processes."
NOAA said the jump in CO2 is partially due to the weather phenomenon known as El Nino, which warms some parts of the world's oceans and causes unusual precipitation and drought patterns.
The rest of the growth is driven by continued high emissions from fossil fuel consumption, said NOAA.
The last time a similar jump in CO2 was observed was in 1998, also a strong El Nino year.
"The impact of El Nino on CO2 concentrations is a natural and relatively short-lived phenomenon," said a statement by World Meterological Organization Secretary-General Petteri Taalas.
"But the main long-term driver is greenhouse gas emissions from human activities. We have the power and responsibility to cut these," he added.
"This should serve as a wake-up call to governments about the need to sign the Paris Climate Agreement and to take urgent action to make the cuts in CO2 emissions necessary to keep global temperature rises to well below 2 degrees Celsius."

And once again you have no evidence to back up your asinine words.

What factual evidence do you have to support the war on women and the gender pay gap really exist?

Facts, not opinions.

Fucking twat.
 


The truth, the whole truth and nothing but the truth:

...Those compiling the global averaged surface air temperature record have not only ignored systematic measurement error, but have even neglected the detection limits of the instruments themselves. Since at least 1860, thermometer accuracy has been magicked out of thin air. Also since then, and at the 95% confidence interval, the rate or magnitude of the global rise in surface air temperature is unknowable. Current arguments about air temperature and its unprecedentedness are speculative theology...

...The uncertainty estimate developed here shows that the rate or magnitude of change in global air temperature since 1850 cannot be known within ±1 C prior to 1980 or within ±0.6 C after 1990, at the 95% confidence interval.

The rate and magnitude of temperature change since 1850 is literally unknowable. There is no support at all for any “unprecedented” in the surface air temperature record.

Claims of highest air temperature ever, based on even 0.5 C differences, are utterly insupportable and without any meaning.

All of the debates about highest air temperature are no better than theological arguments about the ineffable. They are, as William F. Buckley called them, “Tedious speculations about the inherently unknowable.”

There is no support in the temperature record for any emergency concerning climate. Except, perhaps an emergency in the apparent competence of AGW-consensus climate scientists...

The conservation of energy is settled science. If you have any data showing that energy can be created or destroyed I'd be very interested in reading about it.

Where does the energy go?

The conservation of matter and energy is usually taught in eighth grade, you seem to have learned it well, however it should be taught with the caveat that this was the understanding, that works well for non-nuclear reactions, before Einstein's Relativity.
Matter is "destroyed" in nuclear fission and fusion reactions. The atom bomb and the sun are examples were tiny amounts of matter are destroyed to produce extraordinary amounts of energy.
There are no absolute truths or "settled science" only "facts" that are consistent within the system from which they are derived. Our system of science is an approximation to the real world that will never be 100% accurate.

Dr. Evans is correct. Politicians are idiots who should stay out of science.

What?
 
It was really windy here the other day.

Day before that it hit 99 degrees.

Climate continues to change.
 
It is cloudy this morning. Unusual in this climate.
 
tryfail continues to post graphs that show that global temperatures are rising, and fails to grasp that simple concept.
 


More "settled science."



A new paper says that effective climate sensitivity could be as low as 1°C. Here's the abstract.



Estimates of 2xCO2 equilibrium climate sensitivity (EqCS) derive from running global climate models (GCMs) to equilibrium. Estimates of effective climate sensitivity (EfCS) are the corresponding quantities obtained using transient GCM output or observations. The EfCS approach uses an accompanying energy balance model (EBM), the zero-dimensional model (ZDM) being standard. GCM values of EqCS and EfCS vary widely [IPCC range: (1.5, 4.5)°C] and have failed to converge over the past 35 years. Recently, attempts have been made to refine the EfCS approach by using two-zone (tropical/extratropical) EBMs. When applied using satellite radiation data, these give low and tightly-constrained EfCS values, in the neighbourhood of 1°C. These low observational EfCS/two-zone EBM values have been questioned because (a) they disagree with higher observational EfCS/ZDM values, and (b) the EfCS/two-zone EBM values given by GCMs are poorly correlated with the standard GCM sensitivity estimates. The validity of the low observational EfCS/two-zone EBM values is here explored, with focus on the limitations of the observational EfCS/ZDM approach, the disagreement between the GCM and observational radiative responses to surface temperature perturbations in the tropics, and on the modified EfCS values provided by an extended twozone EBM that includes an explicit parameterization of dynamical heat transport. The results support the low observational EfCS/two-zone EBM values, indicating that objections (a) and (b) to these values both need to be reconsidered. It is shown that in the EBM with explicit dynamical heat transport the traditional formulism of climate feedbacks can break down because of lack of additivity.​
