Now media quote scientists probabilistic statements of confidence but still don’t attempt to explain probability to a general readership, partly because reporters are still not willing to explain probability (usually taught to college juniors) to a general readership that includes those who still do not understand fractions (usually taught in 4th grade). Possibly they may also want to confuse the readership or hope readers will demand that reporters stick to some status quo rather than giving them something new they do not understand.
Some media are owned by major stockholders in fossil fuel firms including the Koch brothers. A rule of thumb is that any conclusion that is 90% certain is worthy of further investigation; a conclusion that is 95% certain is twice as good and worthy of publication; a 99% certain conclusion is 5 times as good as a 95% conclusion and outstandingly good; a 99.9% certain conclusion is 10 times as good as a 99% certain conclusion. Now scientists in IPCC say they are 99.9% confident Earth’s climate is in a warming trend and 99% confident that human activity is a major contributing factor to that trend. Scientists who study Earth’s climate before humans invented agriculture, concluded that back then, Milankovich cycles were overall biggest contributing factor, followed by solar radiance cycles, followed by greenhouse gas concentrations, followed by changes in albedo. The invention of agriculture increased methane concentrations from livestock and flood irrigation which prolonged interglacial warm spell. Industrial Revolution added CO2 from burning fossil fuel. Now at 400ppm CO2eq greenhouse gas concentrations are as high as they have been for over a million years. Solar radiance seems to be in a down trend last ten years, 22,000 year Milankovich cycle turned corner at warm end 12/21/2012. Volcanoes in Iceland in September and October emitted lots of SO2 increasing albedo of clouds in northern hemisphere and should cool Earth over 2015. Warmest year since 1860 was 2013. 2014 will likely be in top ten warmest years.
