Accelerating growth in CO₂ levels in the atmosphere

CO₂ Growth In 2016, CO₂ levels in the atmosphere grew by 3.36 ppm (parts per million), a new record since 1959 and much higher than the previous record set in 2015. Worryingly, above graph has a trendline added pointing at a growth rate in CO₂ levels of 6 ppm per year by 2026. Growth in levels of CO₂ in the atmosphere is accelerating, despite reports that - for the third year in a row - carbon dioxide emissions from fossil fuels and industry (including cement production) had barely grown, as illustrated by the Global Carbon Project image below. Why is growth in CO₂ levels in the atmosphere accelerating? So, what makes growth in CO₂ levels in the atmosphere accelerate? As discussed in a previous post , growth in CO₂ levels in the atmosphere is accelerating due to: Deforestation and Soil Degradation: Agricultural practices such as depleting groundwater and aquifers, plowing, mono-cultures and cutting and burning of trees to raise livestock can significantly reduce the carbon content of

More heat on the way

Above image shows temperature anomalies over the Pacific Ocean on February 12, 2017. Note the 19.2°C (34.5 °F) anomaly off the coast of Japan, at the location marked by the green circle. In 2016, the annually-averaged temperature for ocean surfaces around the world was 0.75°C (1.35°F) higher than the 20th century average, higher than the previous record of 2015, NOAA reports . The global annual land surface temperature for 2016 was 1.43°C (2.57°F) above the 20th century average, surpassing the previous record of 2015 by 0.11°C (0.19°F). Note that NOAA uses the the 20th century average as a baseline, for more on different baselines, see  this earlier post . There is more heat on the way, as illustrated by the image below. As above image shows, the El Niño-Southern Oscillation (ENSO) temporarily raises (El Niño) or suppresses (La Niña) global temperatures. Generally, the stronger the event (El Niño or La Niña), the greater its impact on the average global temperature around that time. No

Warning of mass extinction of species, including humans, within one decade

[ click on images to enlarge ] On February 10, 2017, 18:00 UTC it is forecast to be 0.1°C or 32.1°F at the North Pole, i.e. above the temperature at which water freezes. The temperature at the North Pole is forecast to be 30°C or 54°F warmer than 1979-2000, on Feb 10, 2017, 18:00 UTC, as shown on the Climate Reanalyzer image on the right. This high temperature is expected as a result of strong winds blowing warm air from the North Atlantic into the Arctic. The forecast below, run on February 4, 2017, shows that winds as fast as 157 km/h or 98 mph were expected to hit the North Atlantic on February 6, 2017, 06:00 UTC, producing waves as high as 16.34 m or 53.6 ft. A later forecast shows waves as high as 17.18 m or 54.6 ft, as illustrated by the image below. While the actual wave height and wind speed may not turn out to be as extreme as such forecasts, the images do illustrate the horrific amounts of energy contained in these storms. Stronger storms go hand in hand with warmer oceans.
