Climate Change Skepticism: Is the climate change debate being effective isabel marant wedge sneakers online ly argued? Are we hearing equally from both sides?



Here are a few facts:



Current CO2e e = equivalent, so all greenhouse gases together recalculated as CO2 emissions per year human caused: 34bn tons energy and industrial mostly



Current atmo isabel marant wedge sneakers online spheric CO2 PPM parts per million levels: 392



Target PPM level to be sustainable: 350



Resulting CO2e emissions per year: 21bn tons levels from late 80sCO2 emissions to get to in order to first reverse the concentrations: 10bn



Needed reduction: 24bn tons per year



Average net global population increase per year: 70mn people



Average world footprint per capita: 4.7tons CO2e



Average increase in emissions caused by population increase:330mn tons per year



Average annual decrease needed to get to 10bn tons by 2050: 24bn tons / 38 years = 630mn tons



In other words, the world needs to have projects which reduce 1bn tons CO2e per year in order to successfully get to the 10bn tons level. Some greenhouse gases need at least several years and others much longer before they are removed from the atmosphere, so there is likely a time lag of several years before any changes in the data are visible. PPM data shows that whenever emissions were down yearoveryear, the growth of PPM levels was lower 12 years later.



Over time, the sustainable green projects will replace fossil ones and there will be a net reduction in emissions. After they get to c. 10bn tons per year for some years, they can increase to a sustainable level if isabel marant wedge sneakers online needed. isabel marant wedge sneakers online
