Le forçage climatique principal est l’énergie apportée par le soleil sous la forme primaire de rayonnement visible et UV, l’insolation. Son lieu de stockage principal est l’océan, le thermostat de notre planète. Le gaz le plus abondant à côté de l’azote et de l’oxygène est la vapeur d’eau dont la teneur est éminemment variable dans l’atmosphère (de 0,2 % à 7,6 %). John Tyndall conclut dès 1861 que l’effet de serre est dû essentiellement à cette dernière. Il faut rappeler que le potentiel diffusif thermique induit par la vapeur d’eau est 8 fois supérieur à celui du CO2 à concentration égale (0,04 %). L’immense majorité des articles traitant du changement climatique ne prennent en compte que l’hémisphère nord et l’Antarctique. Or, dans l’hémisphère sud (…)

Climate alarmists are constantly trying to justify their misguided goal of decreasing emissions of carbon dioxide (CO2), one of the basic molecules that makes possible life on Earth, by making various claims as to the alleged adverse effects of increasing emissions of CO2. To date these claims have either been shown to be false or better explained by natural causes.

Every day you read about the crisis of climate change and fossil fuel usage and CO2 emissions, and commitments from politicians around the world to “act” to “save the planet.” Surely then, CO2 emissions are in steep decline and headed for zero.
The truth is of course the opposite. In the developed world, rapidly increasing use of “renewables” like intermittent wind and solar energy only serves to drive electricity prices through the roof, while having only the most marginal effect on reducing emissions.

In Africa, food abundance may be driving violent conflict rather than food scarcity, according to a new study. The study refutes the notion that climate change will increase the frequency of civil war in Africa as a result of food scarcity triggered by rising temperatures and drought.

London — Britain’s natural gas fracking industry is using a cold snap that’s gripped large swathes of Europe this week and laid bare weaknesses in the UK’s energy supply to make its pitch.
Britain’s natural gas market has been stretched to its limits as the coldest spell since 2010 tests the nation’s energy and transport network. UK pipeline manager National Grid Plc even urged industry to curb its gas usage while the cold weather persisted. (…)
