Every strange thing is affecting the weather except ... wait for it ... CO2.
Ajax has a contract to spread misinformation about climate change. Just not the threads he starts.
CERN is doing it, HARP is doing it, everything is changing the weather except the one that fossil fuel companies don't want you to blame ... them!
But now we take a break for a message from our sponsors the BOM Australia and their proud partners the CSIRO.
State of the Climate 2018
The global annual mean CO2 level in 2017 was 405 ppm—a 46 per cent increase from the concentration of 278 ppm around the year 1750, and likely the highest level in at least the past two million years. Cape Grim, located at the northwest tip of Tasmania, is one of three key global greenhouse gas monitoring stations in the World Meteorological Organization’s Global Atmosphere Watch program, and has been running continuously for 42 years. Atmospheric concentration of CO2 measured at the Cape Grim Baseline Air Pollution Station shows a steady upward trend, passing 400 ppm in May 2016 and remaining above this level since. The annual average CO2 concentration at Cape Grim in 2017 was 402 ppm.
Measurements of air extracted from Antarctic ice extend the record of measured atmospheric CO2 concentrations to 800,000 years ago. Over the past 2000 years, concentrations were around 280 ppm with only small changes until the start of the industrial era, before rapidly increasing. Over the previous 800,000 years, CO2 concentrations varied between regular warm periods and colder glacial periods but were always lower than those of the past century. The last time atmospheric CO2 concentrations were the same or higher than present day was the Pliocene epoch, more than 2.3 million years ago, as determined from isotopes and organic molecule tracers in ocean sediments. Analysis of the ratio of carbon types, or isotopes, in measured CO2 confirms that the observed increase in atmospheric CO2 is the result of CO2 emissions from human activities such as the combustion of fossil fuels and industrial processes, and changes in land use and land cover.
