10°C or 18°F warmer by 2021?

Skyrocketing emissions On April 21, 2017, at 15:00 UTC, it was as hot as 46.6°C/115.8°F in Guinea, in West-Africa (at the location marked by the green spot on the map below). That same time and day, a little bit to the south, at a spot in Sierra Leona, a level of carbon monoxide (CO) of 15.28 parts per million (ppm) was recorded, while the temperature there was 40.6°C or 105.1°F. Earlier that day (at 13:30 UTC), levels of carbon dioxide (CO₂) of 569 ppm and of sulfur dioxide (SO₂) of 149.97 µg/m³ were recorded at that same spot, shown on the bottom left corner of the image below (red marker). These high emissions carry the signature of wildfires, illustrating the threat of what can occur as temperatures keep rising. Further emissions that come with wildfires are black carbon and methane. Above image shows methane levels on April 22, 2017, AM, at an altitude corresponding to 218 mb. Methane at this altitude is as high as 2402 ppb (magenta indicates levels of 1950 ppb and higher) and whi

The Methane Threat

Carbon dioxide levels in the atmosphere are accelerating. As illustrated by the image below, a linear trend hardly catches the acceleration, while a polynomial trend does make a better fit. The polynomial trend points at CO₂ levels of 437 ppm by 2026. EPA animation: more extreme heat This worrying acceleration is taking place while energy-related have been virtually flat over the past few years, according to figures by the  EIA  and by the  Global Carbon Project . So, what makes growth in CO₂ levels in the atmosphere accelerate? As earlier discussed in this and  this post , growth in CO₂ levels in the atmosphere is accelerating due to continued deforestation and soil degradation, due to ever more extreme weather events and due to accelerating warming that is making oceans unable to further take up carbon dioxide. Ocean warming is accelerating on the Northern Hemisphere, as illustrated by above image, and a warmer Atlantic Ocean will push ever  warmer water into the Arctic Ocean , furt

Gulf Stream is heating up

El Niño 2017 is strengthening. On March 24, temperatures in Africa were as high as 50.6°C or 123°F. The image below shows wildfires hitting Northern China and Far East Russia on April 4, 2017. The Amur River, which forms the boundary between China and Russia, is visible on this Terra/MODIS satellite image, with red dots indicating wildfires. Emissions associated with such wildfires can be huge, as illustrated by the image below. On April 4, 2017, sulfur dioxide (SO₂) levels were as high as 766.29 µg/m³ at a spot (marked by the green circle, left panel) north of the Amur River, in Russia, while carbon dioxide (CO₂) levels were as high as 513 parts per million at that same spot and carbon monoxide (CO) levels there were as high as 17,402 parts per billion. These high sulfur dioxide levels indicate that sulfur that has over the past few decades been deposited there from smokestacks of coal-fired power plants, tailpipes of vehicles, etc., can re-enter the atmosphere as a result of wildfire

Mainstream Media Biased By Focusing On Climate Denial

Hearings of the House Committee on Science, Space and Technology recently degenerated into a farce, as three fringe scientists were paraded next to “mainstream-scientist” Michael Mann. The Hearing turned out to have little or no intention to live up to its stated goal of examining the “scientific method and process as it relates to climate change” and instead turned into a theater to stage climate science denial . Reports of the event confirmed the bias of mainstream media to focus on climate denial while ignoring the side of the Climate Spectrum that is sounding the alarm, as also illustrated by the image below. Indeed, in discussions on climate change, why ignore the side of the Climate Spectrum that is sounding the alarm? Accordingly, a  poll at the ArcticNews group asked: “Who would you instead like to appear in a discussion with Michael Mann?” The results are shown below: It must be said that not all media are ignoring the warnings. Some media did pick up alerts, e.g. those conta
