Statistician Bjorn Lomborg had already pointed out that the Paris CO2 emission promises would cost $100 trillion dollars that no one has, and make only a 0.05-degree difference in Earth’s 2100 AD temperature. Others say perhaps a 0.2 degree C (0.3 degrees F) difference, and even that would hold only in the highly unlikely event that all parties actually kept their voluntary pledges.

For the last 3 years, human CO2 emissions rates have not risen. In fact, according to the IEA, we burned slightly more fossil fuels in 2014 than we did in both 2015 and 2016.
Despite the lack of growth – even slight decline – in human emissions rates during 2014 – 2016, the atmospheric CO2 parts per million (ppm) concentration grew rapidly – by more than 8 ppm (397 ppm to 405 ppm).

One of the many conundrums facing climate alarmists — who predict that dangerous future global warming will result from increasing concentrations of atmospheric CO2 — is the existence of the aptly-named “warming hiatus.” Also referred to as the “warming pause,” this phenomenon describes a nearly two-decade-long leveling off of global temperatures despite a ten percent increase in atmospheric CO2 concentration since 1998. The significance of these observations resides in the fact that all climate models project that temperatures should not be levelling off, but should be increasing (despite interannual variability) in direct consequence of the ongoing rise in atmospheric CO2.

Until cloud and precipitation data are adequate AND accounted for properly AND the error bands are low enough to cover 1/10 degree increments, we can’t say there is ANY effect from CO2 on temperature. It is at most a conjecture, and not a very good one. You can not ignore the major driver of changes of temperatures (as shown in the above graph) and then attribute temperature changes to something else by supposition.

Since the 19th century, use of chemical methods has provided reliable atmospheric CO2 gas analyses results that have been obtained predominantly from the northern hemisphere. These direct chemical analyses results provide information on past atmospheric CO2 concentrations in addition to the modern direct atmospheric CO2 measurements since 1958 and the indirect reconstructions of past atmospheric CO2 from ice cores. Comprehensive literature indicates that the chemical methods have provided a systematic accuracy within ± 3 Vol% since 1857.

If Australia emits 1.5 per cent of global annual CO2 emissions, 3 per cent of the total annual global emissions are anthropogenic and the atmosphere contains 400 parts per million by volume of CO2, then one molecule in 6.6 million molecules in the atmosphere is CO2 emitted from humans in Australia. This molecule has an atmospheric life of about 7 years before it is removed from the atmosphere by natural sequestration into life and limey sediments.

In their seminal paper on the Vostok Ice Core, Petit et al (1999)  note that CO2 lags temperature during the onset of glaciations by several thousand years but offer no explanation. They also observe that CH4 and CO2 are not perfectly aligned with each other but offer no explanation. The significance of these observations are therefore ignored. At the onset of glaciations temperature drops to glacial values before CO2 begins to fall suggesting that CO2 has little influence on temperature modulation at these times.

The basic physics behind CO2 warming the oceans, and therefore the atmosphere simply don’t exist. The only defined mechanism by which CO2 can affect climate change is by “thermalizing” long-wave infrared radiation between 13 and 18-microns. In reality, there is another one, radiation, but that carries heat away from the earth and results in atmospheric cooling.

The conventional basic climate model applies “basic physics” to climate, estimating sensitivity to CO2. However, it has two serious architectural errors. It only allows feedbacks in response to surface warming, so it omits the driver-specific feedbacks

Germany is failing horribly to reach its emissions targets, as the following chart in the report shows.

The EU’s total greenhouse gas emissions increased in 2015 for the first time since 2010.
According to new data published by the European Environment Agency (EEA), the 0.5% increase happened largely due to increasing demand for transport – better fuel efficiency in the sector was not enough to offset this.

A new global assessment reveals that increases in leaf abundance are causing boreal areas to warm and arid regions to cool. The results suggest that recent changes in global vegetation have had impacts on local climates that should be considered in the design of local mitigation and adaptation plans.

The core of Salby’s theory is derived using CO2 data from MLO’s Keeling Curve since 1958, and satellite temperature data since 1979. (His few charts reaching back to 1880 contain acknowledged large uncertainties.) His theory builds off a simple observation, that in ‘official’ estimates of Earth’s carbon cycle budget, anthropogenic CO2 is only a small source compared to large natural sources and sinks.
by Keenan et al., November 8, 2016, Nature
Terrestrial ecosystems play a significant role in the global carbon cycle and offset a large fraction of anthropogenic CO2 emissions. The terrestrial carbon sink is increasing, yet the mechanisms responsible for its enhancement, and implications for the growth rate of atmospheric CO2, remain unclear.
Jim McIntosh , David Mulberry and 2 others posted in Air-Climate-Energy (Jim McIntosh 9 May at 11:18): Reposting because those AGW alarmists hate this report. Yes, plants are doing it better than any carbon tax and they do it for free… as long as we don’t cut them down. You’d think we’d learn by now that managing climate comes back to how we have mismanaged the planet’s forests.
