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 wildfires, confirming the conclusion of earlier studies such as by Hegg et al.

This indicates that sulfur levels in the atmosphere are higher than previously estimated, given that most previous estimates were mainly based on real-time emissions from industrial activity at the time. When adding revolitalization of previously-deposited sulfur (due to wildfires) into the picture, estimates for such aerosols' masking effect of the full wrath of global warming will be higher than previously thought, and increasingly so, as wildfires are becoming painfully more common as Earth continues to warm up.

This also implies that it becomes increasingly plausible that, when aerosol levels suddenly drop during heatwaves, wet bulb temperature starts crossing sustainability limits for humans without air-conditioning. Note that in July 2016, weather conditions at a spot in the U.S. came perilously close to this limit.

What could further contribute strongly to a rapid rise in global temperature is the combination of decline of Earth's snow and ice cover and eruptions of methane from the seafloor of the Arctic Ocean.

The Gulf Stream is heating up as the 2017 El Niño strengthens, fueled by record low global sea ice extent, which means that a lot of extra heat is getting absorbed globally (image below, by Wipneus).

Both Arctic and Antarctic sea ice extent were are record low on April 1, 2017, as the images below show. 

Sea surface temperatures were as much as 5.9°C or 10.6°F warmer than 1981-2011 at the location marked by the green circle on the image below.

Over the next half year, increasingly warm waters will be carried by the Gulf Stream from the coast of North America to the Arctic Ocean. As this warmer water arrives in the Arctic Ocean, there will no longer be a large buffer of sea ice there to consume the heat, as was common for the past thousands of years and longer. Additionally, warmer water looks set to arrive in an Arctic Ocean that will be heated up like we've never seen before, as so much of the sunlight reaching the surface of the Arctic Ocean doesn't get reflected back into space anymore and as temperatures again look set to reach record highs in the Arctic during the northern summer.

Where can all this extra heat go? Sea ice will start sealing off much of the surface of the Arctic Ocean by the end of September 2017, making it hard for more heat to escape the Arctic Ocean by entering the atmosphere. The extremely dangerous situation is that it looks like much of the extra heat will instead reach sediments at the seafloor of the Arctic Ocean that contain huge amounts of methane in currently still frozen hydrates.

An image in an earlier post showed many cracks in the sea ice north of Greenland. Above image shows that huge cracks are also present in the sea ice in the Beaufort Sea.

On the combination images above and below, high concentrations of methane show up all over the Arctic Ocean, specifically over the Beaufort Sea and over and around Greenland. Note also the methane showing up over Antarctica, as discussed in an earlier post.

Earth losing her sea ice

Earth is losing her sea ice. Arctic sea ice was at record low extent for the time of the year on March 24, 2017, as illustrated by the image below.

As the image below shows, on March 24, 2017, Arctic sea ice featured many cracks (top of Greenland is bottom left and Svalbard is on the right).

The poor state of Arctic sea ice is also reflected by the sea ice volume, as depicted by the image below, by Wipneus, showing PIOMAS anomalies up to March 2017.

On March 24, 2017, Antarctic sea ice extent was also much lower than it used to be at this time of year, as illustrated by the image below.

Altogether, global sea ice extent has now been at a record low for many months, as illustrated by the graph by Wipneus below. This means that a huge amount of additional sunlight has been absorbed over these months, instead of getting reflected back into space as before.

As Earth loses her sea ice, tipping point look set to be crossed that could result in rapid acceleration of Earth's temperature, as discussed at the extinction page, which warns that surface temperatures of the atmosphere could rise by some 10°C or 18°F within a decade, i.e. by 2026.

The situation is dire and calls for comprehensive and effective action, as described in the Climate Plan.

Which Trend Is Best?

NASA just released temperature data for February 2017. Should we be worried? Yes, there are many reasons to be very worried.

Let’s go back in time. This is from a post written ten years ago:
We may suddenly face a future in which many if not most people will have little or no access to food, water, medicines, electricity and shelter, while diseases go rampant and gangs and warlords loot and devastate the few livable areas left. Human beings as a species will face the risk of total extinction, particularly if many species of animals and plants that humans depend on will disappear. The post continues: Many people are still in denial about the severity of the problem of global warming, the accumulation of dangers and their progression. 

Indeed, even today many people will still deny that such events could strike suddenly, e.g. within a few years time. Many people use linear trends to predict the future many years from now. As an example, the straight blue line on the graph below is a linear trend based on NASA 1880-current meteorological stations data. The problem is that linear trends, especially when based on data that go back many years, can make people overlook important recent changes such as the temperature rise that has taken place over the past few years, the decline of glaciers and sea ice and the recent increases in concentrations of carbon dioxide in the atmosphere.

[ click on image to enlarge ]

An alternative approach is to use recent data, e.g., from the year 2012, and then calculate a polynomial trend that extends a few years into the future. Taking such an approach can result in a polynomial trend (red curved line) that is contained in the NASA Land+Ocean data from January 2012 to February 2017. This trend shows the potential for a 10°C (18°F) rise four years from now, and this should act as a powerful warning.

The appropriateness of linear versus non-linear trends was also discussed earlier at the Controversy page.

In addition to looking at trends that are contained in such data, it makes sense to analyse the different elements contributing to such a rise. Such elements are discussed in more detail at the extinction page, which confirms the potential for a 10°C temperature rise within years, i.e. by the year 2026.

The situation is dire and calls for comprehensive and effective action as described in the Climate Plan.

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 soils, along with soil moisture and nutrients levels.
• Climate change and extreme weather events:
  The recent jump in global temperature appears to have severely damaged soils and vegetation. Soil carbon loss and enhanced decomposition of vegetation appear to have occurred both because of the temperature rise and the resulting extreme weather events such as heatwaves, drought, dust-storms and wildfires, and storms, hail, lightning, flooding and the associated erosion, turning parts of what was once a huge land sink into sources of CO₂ emissions.
  Moreover, extreme weather events can also lead to emissions other than CO₂ emissions, such as soot, nitrous oxide, methane and carbon monoxide, which can in turn cause a rise in the levels of ground-level ozone, thus further weakening vegetation and making plants even more vulnerable to pests and infestations.
• Oceans appear to be unable to further take up CO₂:
  Oceans appear to have turned from sinks into sources of CO₂, releasing CO₂ into the atmosphere. As discussed earlier, oceans are getting warmer, and warm water holds less oxygen than cold water. Furthermore, as the water warms, it tends to form a layer at the surface that does not mix well with cooler, nutrient-rich water below, depriving phytoplankton of some of the nutrients they need to grow. A study by Boyce et al. found a decrease of about 1% per year of phytoplankton in oceans globally. Sergei Petrovskii, co-author of a 2015 study, found that a rise in the water temperature of the world’s oceans of about 6°C could stop oxygen production by phytoplankton by disrupting the process of photosynthesis, adding that “About two-thirds of the planet’s total atmospheric oxygen is produced by ocean phytoplankton – and therefore cessation would result in the depletion of atmospheric oxygen on a global scale. This would likely result in the mass mortality of animals and humans.”

Biomass

Sensitivity

Meanwhile, research including a 2014 study by Franks et al. concludes that the IPCC was too low in its estimates for the upcoming temperature rise locked in for current CO₂ levels. A study by Friedrich et al. updates IPCC estimates for sensitivity to CO₂ rise, concluding that temperatures could rise by as much as 7.36°C by 2100 as a result of rising CO₂ levels.

When also taking further elements than CO₂ more fully into account, we could face an even larger temperature rise, i.e. a rise of 10°C (or 18°F) by 2026 (compared to pre-industrial), as further described at the extinction page that specifies the different elements of such a rise, including a 0.5°C rise due to CO₂ emissions from 2016 to 2026. The CO₂ growth discussed in this post appears to be in line with such a rise and in line with the associated loss of carbon sinks and rising vulnerability of carbon pools.

The situation looks particularly threatening in the Arctic where many of the most vulnerable carbon pools are located, where temperatures are rising fastest and where CO₂ levels have recently risen rapidly (see image below with CO₂ readings at Barrow, Alaska).

Also note the recent rise in methane readings at Barrow (image below).

Action is needed!

The situation is dire and calls for comprehensive and effective action, as described in the Climate Plan.

2016 well above 1.5°C

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.

[ click on images to enlarge ]

To some extent, the rise above 1.5°C was due to El Niño, as the trendline indicates, but the trend also indicates that temperatures will cross the 1.5°C mark in 2017 even if 2017 will be El Niño/La Niña-neutral.

Worryingly, another El Niño is actually forecast for 2017, as discussed in an earlier post.

Even more worrying is that rise of this trendline could well be too conservative.

Ocean temperatures are rising rapidly, as illustrated by the image on the right, and the rapid warming of the oceans is causing a dramatic fall in sea ice extent, as illustrated by the image below and as discussed in an earlier post.

The lack of sea ice spells trouble. Not only is snow and ice decline causing more sunlight to be absorbed (rather than getting reflected back into space as before), there are further feedbacks associated with this. As the temperature difference between the Arctic and the Equator decreases, changes are taking place to wind patterns that cause further acceleration of warming in the Arctic, as discussed in an earlier post. This in turn threatens to trigger huge amounts of methane to erupt abruptly from the seafloor.

Methane levels over the Arctic Ocean are much higher than over the rest of the world, as illustrated by the image below, showing the situation in the afternoon of January 17, 2017, with peaks reaching levels as high as 2406 ppb. Particularly worrying are the solid magenta-colored areas over the East Siberian Arctic Shelf, indicating methane levels above 1950 ppb.

When also taking into account further elements that could cause warming, a potential warming of 10°C (18°F) could eventuate by the year 2026, i.e. within about nine years from now, as discussed at the extinction page and as illustrated by the image below, from the Temperature page.

The situation is dire and calls for comprehensive and effective action, as described at the Climate Plan.

Global sea ice extent falling off chart

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 of melting itself. However, it now looks like the temperature of the atmosphere is catching up fast, as illustrated by the image below.

[ click on images to enlarge ]

On the right is a forecast by the European Centre for Medium-Range Weather Forecasts (ECMWF).

It shows that we’ve barely been in a La Niña, which typically makes the atmosphere cooler than it would otherwise have been.

Already now, another El Niño is on the way that could soon make it up to 2.5°C warmer than it is was late last year.

Global sea ice volume is also at record low, as illustrated by the image below on the right.

Arctic sea ice thickness hit a record low in November 2016 when thickness fell below 0.7 m or 2.3 ft.

As the ice gets thinner, the risk of collapse grows, as increasingly stronger winds and storms and stronger wave action can more easily break up thin sea ice, making it more vulnerable to melting and to get carried out of the Arctic Ocean by stronger cyclonic winds and stronger exit currents.

Disappearance of Arctic sea ice increases the risk of huge methane releases from the seafloor of the Arctic Ocean. The outlook is terrifying. As I calculated last year, surface temperatures of the atmosphere could rise by some 10°C or 18°F within a decade, i.e. by 2026.

The situation is dire and calls for comprehensive and effective action, as described in the Climate Plan.

Accelerating Warming of the Arctic Ocean

Stronger Winds causing further Warming of the Arctic Ocean

Warming is accelerating in the Arctic. On December 22, 2016, the Arctic was on average 3.33°C or 5.99°F warmer than it was in 1979-2000.

Within the Arctic, the Arctic Ocean is warming most rapidly. The image below gives a snapshot of the situation on December 22, 2016 at 06:00 UTC. The Arctic as a whole was as much as 3.34°C or 6.01°F warmer than in 1979-2000. At the same time, temperatures over much of the Arctic Ocean were at the top end of the scale, i.e. as much as 30°C or 54°F warmer than in 1979-2000 (pink color at 90°N latitude).

The temperature in the Arctic (north of 80°N Latitude) is also illustrated by the image below. The red line of the temperature for 2016, up to December 22, 2016. The green line is the 1958-2002 temperature.

Over the entire year 2016, warming was most profound over the Arctic Ocean, which was more than 2.5°C or 4.5°F warmer than 1981-2010, as illustrated by the image below.

The animation below illustrates how this anomaly developed over the past few years, each time showing a 365-day period, starting in 2014 and each time shifted by roughly one month.

These high temperatures over the Arctic Ocean reflect warm water of the Arctic Ocean, with heat added from the Atlantic Ocean and the Pacific Ocean. The image below shows ocean warming, with temperatures rising particularly rapidly on the Northern Hemisphere.

[ Ocean warming, from earlier post ]

Warmer water of the Atlantic Ocean is pushed by the Coriolis force toward the Arctic Ocean. The huge amounts of energy entering the oceans translate not only into higher temperatures of the water and of the air over the water, but also into higher waves and stronger winds.

Above image shows winds on December 29, 2016.

[ click on images to enlarge ]

As above image shows, waves were as high as 7.65 m or 25.1 ft in between Norway and Svalbard on December 29, 2016.

Sea surface temperatures west of Svalbard were as high as 14.6°C (58.2°F) on December 29, 2016. Sea surface temperature went up at the end of December at this spot, while the longer-term average went down in line with the change in seasons.

Underneath the surface of the North Atlantic, the water is much warmer than at the surface, and this temperature difference increases as winds get stronger and cause stronger evaporation, which has a cooling effect on the sea surface. This is illustrated by the image below, showing both the North Pacific and the North Atlantic on November 28, 2016.

The fact that the North Pacific shows a huge cold area, while the cold area in the North Atlantic has virtually disappeared, suggests that the cold area in the North Pacific is not the result of melt-water. The path of the cold areas and the low temperatures over the continents at higher latitudes, give further indications that strong winds are causing such cold areas. The image below shows that a cold area reappearing in the North Atlantic as it gets hit by strong winds (see video further below).



Above images and the image below, from an earlier post, illustrate how stronger evaporation and the resulting precipitation, at times in combination with melt-water, could create cold freshwater lids on both the North Atlantic and the North Pacific. The situation in the North Atlantic is very dangerous, as such a lid can cause much more heat to get carried into the Arctic Ocean underneath the sea surface of the North Atlantic, due to reduced heat transfer to the atmosphere from water on its way to the Arctic Ocean.


The image below, from an earlier post,  shows the depth of Barents Sea, which is relatively shallow around Svalbard.

As the image on the right shows, this spot warms up due to a sea current that brings warm water from the North Atlantic into the Arctic Ocean.

Above images give an indication of the temperature of the water in the Atlantic Ocean underneath the sea surface, as the water comes to the surface near Svalbard, as also illustrated by the plot on the right.

The Arctic Ocean is now warming underneath the sea ice due to the inflow of warm water from the Atlantic Ocean and the Pacific Ocean.

The Arctic Ocean is also warming due to feedbacks such as increased levels of water vapor in the atmosphere, warmer river water running into the Arctic Ocean and soot from wildfires that can settle on snow and ice, resulting in further albedo changes.

Further feedbacks of global warming include warmer air temperatures, higher waves and stronger winds that all speed up the demise of snow and ice.

Stronger winds are pushing warm water from the North Atlantic into the Arctic Ocean. Why are these winds getting stronger? As the Arctic warms faster than the rest of the world, the temperature difference between the Arctic and the Equator decreases, making the Jet Stream wavier, with longer loops extending to the north and to the south. At the same time, the temperature difference between the oceans and the continents (Europe, Asia and North America) is increasing, speeding up the Jet Stream as it travels, e.g., over the North Atlantic towards the Arctic Ocean.

[ click on images to enlarge ]

The above 14.6°C SST on December 29, 2016, near Svalbard is the result of warm water being pushed from the North Atlantic into the Arctic Ocean. The situation is illustrated by the above combination image that shows that the Jet stream is forecast to reach speeds as high as 319 km/h or 198 mph in between North America and Greenland on December 31, 2016 (left panel). At the same time, surface winds are forecasts to reach speeds as high as 95 km/h or 59 mph (center panel) and waves as high as 8.96 m or 29.4 ft in between Norway and Svalbard (right panel).

The situation is further illustrated by the video below, showing winds over the North Atlantic from December 27, 2016 to January 3, 2017, as forecasts by cci-reanalyzer.org.

The fact that this is not a one-off event is also illustrated by the image on the right, showing that the Jet Stream reached speeds of 384 km/h or 239 mph over the Pacific Ocean on December 27, 2015. At the same day and time in 2015, the Jet Stream reached speeds as high as 430 km/h or 267 mph as it moved over North America on its way over the North Atlantic.

In conclusion, increasingly stronger winds are causing huge amounts of heat to enter the Arctic Ocean from the North Atlantic, and also from the Pacific Ocean. As the water of the Arctic Ocean keeps warming, the danger increases that methane hydrates at the bottom of the Arctic Ocean will destabilize.

The danger is illustrated by the two images above and below, recorded by the MetOp2 satellite on the afternoon of Christmas eve and Christmas.

Continued warming could trigger huge abrupt methane eruptions leading to mass destruction and extinction.

Potential warming by more than 10°C or 18°F by 2026 (from: Climate Plan Summary, see also: the extinction page)

The image below shows the associated temperature rise from preindustrial to 2026, with figures discussed in more detail on the Temperature page.

The situation is dire and calls for comprehensive and effective action as described at the Climate Plan.

Two videos complement this. Have a look at the video entitled Abrupt Climate Disrupting Arctic Changes: Part 2 of 2 by Paul Beckwith, in particular the segment from 8:30 to 12:00 minutes where Paul discusses how wind patterns are changing over the Arctic.

For further thoughts on the situation, also have a look at the video below in which Jennifer Hynes interviews Peter Wadhams.
