Accelerating growth in CO₂ levels in the atmosphere

Image
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

Image
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...

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

Image
[ 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 ocea...

Arctic Ocean Feedbacks

Image
The world is warming rapidly, and the Arctic is warming much more rapidly than the rest of the world. In December 2016, the temperature anomaly from latitude 83°N to the North Pole was 8 times as high as the global anomaly. Above forecast for February 6, 2017, shows that temperatures over parts of the Arctic Ocean will be as much as 30°C or 54°F higher than they were in 1979-2000. How can it be so much warmer in a place where, at this time of year, little or no sunlight is shining? The Arctic Ocean is warming particularly rapidly due to a multitude of feedbacks, some of which are illustrated on the image below. As the Arctic is warming more rapidly than the rest of the world, the temperature difference between the Arctic and the northern latitudes decreases, which makes the jet stream wavier. Jennifer Francis has written extensively about jet stream changes as a result of rapid warming in the Arctic. In the video below, Peter Sinclair interviews Jennifer Francis on these changes. Th...

Can the world be saved without geoengineering?

Image
Can the world be saved without geoengineering? What is your view? The Climate Plan includes the more effective and safe geoengineering methods as separate lines of action, next to emission cuts. There are discussions on this at the Climate Alert group . Feel encouraged to join in! In the following videos, a number of geoengineering methods are discussed. The videos were recorded in Marrakesh, Morocco, at the time of the UN climate negotiations that were held from 7-18 November 2016. Stuart Scott interviews Peter Wadhams, Hugh Hunt, Matthias Honegger and Douglas MacMartin. Geoengineering, our last chance? Can technology save us?

2016 well above 1.5°C

Image
In December 2016, it was 6.58°C (11.84°F) warmer from latitude 83°N to the North Pole. In December 2016, the world as a whole was on average 0.82°C (1.47°F) warmer than in 1951-1980. Temperatures are rising fast, and especially so over the Arctic Ocean. In February 2016, the world was 1.34°C (2.41°F) warmer than 1951-1980, while part of the Kara Sea was 11.3°C (20.34°F) warmer than 1951-1980, as the image on the right illustrates. The 1951-1980 period is the default baseline used by NASA. When comparing the current temperature to years such as 1900 or 1750, the difference will be even larger, as illustrated by the image below. In 2016, the global temperature was well above the 1.5°C (2.7°F) guardrail set by the Paris Agreement. This is illustrated by the different baselines used in image below (the use of different baselines was discussed in an earlier post ), given that the Paris Agreement uses preindustrial levels as baseline.

Global sea ice extent falling off chart

Image
Global sea ice extent is falling off the chart, as illustrated by the image below. [ click on images to enlarge ] The National Snow & Ice Data Center (NSIDC) is one of the world's best-know archives for satellite data on sea ice. In its recent news release , NSIDC notes that the difference between the 1981-2010 average global sea ice extent and the 2016 extent was over 4 million km² in mid-November 2016 (image on the right). The fall in sea ice extent constitutes a huge amount of energy that is no longer reflected back into space and is instead absorbed by the ocean, the atmosphere and by the process of melting itself. In line with earlier calculations by Professor Peter Wadhams, a 4 million km² sea ice decrease could equate to a radiative forcing of as much as 1.3 W/m². All this extra energy does not directly translate into a rise in temperature of the atmosphere, since a lot of energy has over the past few decades been absorbed by the ocean and has also gone into the process ...
