On our 4.54 billion year old planet, life is perhaps as much as 3.7 billion years old, photosynthesis and multi-cellularity dozens of times independently around 3.0 billion years old, and the emergence of plants, animals, and fungi onto land, by at least the Ordovician period, perhaps 480 million years ago, forests appearing around 370 million years ago, and the origin of modern groups such as mammals, birds, reptiles, and land plants subsequently. The geological record shows that there have been five major extinction-events in the past, the first of them about 542 million years ago, and suggests that 99% of the species that ever lived (5 billion of them?) have become extinct. The last major extinction event occurred about 66 million years ago, at the end of the Cretaceous Period, and, in general, the number of species on earth and the complexity of their communities has increased steadily until near the present.

Aluminum Can Story

This aluminum can, named Miles, is here to tell you a thing or two about how far he travels to do his job. He's exhausted!

A charming animation that really drives home the point that we need to be more aware of how much energy is wasted in the production and transportation of goods we use everyday, and what we can be doing instead.

Security Experts Identify 12 Likely Triggers of War as the Planet Warms
Lorraine Chow 09 June 2017

Climate change isn't just causing glaciers to melt, sea levels to rise and forests to set fire. It has becoming increasingly evident that Earth's rising temperatures also threatens international security.

In fact, an analysis released Friday by the Center for Climate and Security has identified 12 "epicenters," or categories, where the world's rising temperatures could trigger major global conflict.

"Any one of the climate and security epicenters can be disruptive," said Caitlin Werrell, co-president of the Center for Climate and Security and editor of the report, Epicenters of Climate and Security: The New Geostrategic Landscape of the Anthropocene. "Taken together, however, these epicenters can present a serious challenge to international security as we understand it."

The categories include eroding state sovereignty, low-lying nations going underwater, as well as the disruption in the global coffee trade that employs 125 million people worldwide.

Previous studies have identified how terrorist groups in certain regions are taking advantage of increasingly scarce natural resources such as water and food as a "weapon of war." Additionally, a U.S. military report from 2014 called climate change a "catalyst for conflict" and a "threat multiplier." President Obama once said that "no challenge poses a great threat than climate change, and it's an "immediate risk to our national security."

Meanwhile, President Trump and many top officials in his administration brush off or reject the science of climate change. Conservative media has also mocked the idea that climate change is related to the growth of terrorism. And let's not forget Trump's middle finger to the world when he dropped the U.S. out of the Paris climate agreement, which has been signed by every nation on Earth except war-torn Syria and Nicaragua, which didn't think the accord was strong enough.

The Center for Climate and Security report stresses why mitigating climate change should be the highest priority for governments and institutions around the world.

"This report demonstrates the kind of cross-sectorial thinking needed to anticipate and mitigate climate-related systemic risks—risks that will be disruptive at local, national, regional and global levels," said Francesco Femia, co-president of the Center for Climate and Security and editor of the report. "Security risks thousands of miles away can have an effect on us at home. Understanding that can help advance preventive rather than reactive solutions."


These are the 12 epicenters identified by the security experts in the report:


1. Eroding State Sovereignty: An inability to absorb the stresses of a rapidly-changing climate may erode state sovereignty (Francesco Femia and Caitlin Werrell);

2. Disappearing Nations: Many low-lying nations are in danger of being completely submerged by rising seas (Andrew Holland and Esther Babson);

3. Conflict Over Melting Water Towers: Climate change can increase tensions and conflict among the 4 billion people dependent on mountain “water towers" (Troy Sternberg);

4. Conflict Over Fisheries: A warming ocean is driving critical fish stocks into contested waters, contributing to conflict between states (Michael Thomas);

5. Tensions in a Melting Arctic: Increased activity in a melting Arctic raises new security and geopolitical risks (Katarzyna Zysk and David Titley);

6. Weaponized Water: As climate change exacerbates water stress, non-state actors, including international terrorist organizations, are increasingly using water as a weapon (Marcus King and Julia Burnell);

7. Disrupted Strategic Trade Routes: Climate change will place strains on maritime straits that are critical for global trade and security (Adam H. Goldstein and Constantine Samaras);

8. Compromised Coffee Trade: Climate change may also disrupt critical global trading networks, like the coffee trade. which currently supports 125 million people worldwide (Shiloh Fetzek);

9. More (and Worse) Pandemics: Climate change may increase the likelihood and range of pandemics, which could threaten global security (Kaleem Hawa);

10. Flooded Coastal Megacities: Rapidly expanding coastal megacities are threatened by climate impacts like sea level rise, which can destabilize nations (Janani Vivekenanda and Neil Bhatiya);

11. Increased Displacement and Migration: Climate change is becoming a more significant driver of migration and displacement (Robert McLeman);

12. Enhanced Nuclear Risks: Climate change, nuclear security, and policies that are not sensitive to both simultaneously, can increase regional and global security threats (Christine Parthemore)

Here is a video introduction to the report:

High Waves Set To Batter Arctic Ocean

High temperatures hit Pakistan end May 2017. The image below shows readings as high as 51.1°C or 123.9°F on May 27, 2017 (at green circle).


As the image below shows, sea temperature was as high as 32.6°C or 90.6°F on May 28, 2017 (at the green circle), 1.8°C or 3.2°F warmer than 1981-2011.



High temperatures over land and at the sea surface reflect an atmosphere that contains huge amounts of energy. On May 28, 2017, the Convective Available Potential Energy (CAPE) reached levels as high as 7448 J/kg at the location in the United States marked by the green circle. Storms hit a large part of the United States, with baseball-sized hail reported on May 27, 2017.

Agelbert NOTE: Go to article link for referenced link.

Here's a link to a reported 56 °C (132 °F) temperature recorded in Iran and here's a link to an article describing a May 28, 2017, reading in Turbat, Pakistan, initially reported by the Pakistan Meteorological Department as 53.5°C (128.3°F) and later upgraded to 54.0°C (129.2°F.)

How could it be possible for growth of energy in the atmosphere to be accelerating, when CO₂ emissions from fossil fuels and industry (including cement production) have barely shown any recent growth, as discussed in an earlier post and as reported by EIA?

The image below depicts this possibility, while a recent post discussed the following scenario:



Warmer water tends to form a layer at the surface that does not mix well with the water underneath, as discussed before. Stratification reduces the capability of oceans to take up heat and CO₂ from the atmosphere. Less take-up by oceans of CO₂ will result in higher CO₂ levels in the atmosphere, further speeding up global warming.

Additionally, 93.4% of global warming currently goes into oceans. The more heat will remain in the atmosphere, the faster the temperature of the atmosphere will rise. This feedback can cause very rapid and strong global warming. as depicted on the image on the right and as also described as feedback #29 on the feedbacks page.

With this in mind, forecasts of storms hitting the Arctic Ocean over the next few months look even more frightening.


Waves as high as 2.34 m or 7.7 ft are forecast to hit the Arctic Ocean on June 8, 2017, at the location marked by the green circle.


How is it possible for waves to get that high in a part of the Arctic Ocean that is surrounded by continents that act as shields against winds?

On June 8, 2017, temperatures are forecast to be as high as 40.6°C or 105.2°F near Phoenix, Arizona, and as high as 26.0°C or 78.7°F in Alaska, as the image below shows.


The image below shows that on June 12, 2017, temperatures as high as 35.1°C or 95.3°F were recorded over a river in Siberia that ends in the Lena River which in turn ends in the Arctic Ocean (left panel, green circle), while waves near Novaya Zemlya were recorded as high as 4.54 m or 14.9 ft (top right panel, green circle).


The image below shows that on June 6, 2017, temperatures on the coast of Hudson Bay (green circle) were as high as 31.6°C or 89°F.


Four cyclones are visible on the above image. Strong winds over the Arctic Ocean can cause high waves that can break up the sea ice and strengthen currents that are pushing warm water into the Arctic Ocean and sea ice out of the Arctic Ocean.

These stronger winds, currents and waves come at a time that the Arctic sea ice thickness is at record low, as illustrated by the image below by Wipneus and underneath by Larry Hamilton.


Let's take a closer look at some further feedbacks that are at work behind the increasingly thinner ice, higher temperature, stronger wind and higher waves in the Arctic.

• Sea Ice Decline - The snow and ice cover over the Arctic Ocean make that sunlight is reflected back into space (albedo loss). In the absence of this cover, the Arctic Ocean will absorb more heat. Furthermore, open oceans are less efficient than sea ice when it comes to emitting in the far-infrared region of the spectrum.


• Buffer Loss - The snow and ice cover over the Arctic Ocean acts as a buffer, absorbing heat that in the absence of this buffer will have to be absorbed by the Arctic Ocean, as discussed in earlier posts such as this one.

• Jet Stream Changes - Rising temperatures in the Arctic are causing wind patterns to change, in particular the jet stream.

As a result, warm air can more easily get carried by wind from land over the Arctic Ocean.

The image below shows the Jet Stream on June 6, 2017. As temperatures over the Arctic rise faster than they do at the Equator, the jet stream becomes more wavy. Instead of circumnavigating Earth in a straight and narrow band that keeps the cold air over the Arctic separate from warmer temperatures south of the jet stream, a more wavy jet stream enables more warm air to flow into the Arctic and more cold air to leave the Arctic.



Winds are particularly strong over oceans and, as the Atlantic Ocean keeps warming up, those winds can push more warm water into the Arctic Ocean, as discussed in an earlier post. This can dramatically warm up the water of the Arctic Ocean.

• Clouds and Water Vapor - Loops of the jet stream extending over the Arctic can also bring stronger winds and more clouds and water vapor into the Arctic.

This is another self-reinforcing feedback that goes hand in hand with the above feedbacks. As temperatures rise in the Arctic, loss of sea ice will increase, resulting in more open water. This, in combination with stronger winds and warmer water will also result in more clouds and water vapor over the Arctic, further speeding up the temperature rise in the Arctic.

• Decline of Snow and Ice Cover on Land - Rising temperatures in the Arctic are also speeding up the decline of the snow and ice cover on land. This will result in albedo loss and will also trigger further feedbacks, such as soil destabilization and warm water from rivers flowing into the Arctic Ocean.

• Soil destabilization - Heatwaves and droughts destabilize the soil. Soil that was previously known as permafrost, was until now held together by ice. As the ice melts, organic material in the soil starts to decompose and the soil becomes increasingly vulnerable to wildfires. All his can result in high emissions of CO₂, CH₄, N₂O, soot, etc., which in turn causes further warming, specifically over the Arctic. The danger of wildfires is illustrated by the image below.


• Warmer Rivers - High temperatures on land can strongly warm up water of rivers flowing into the Arctic Ocean. This is also illustrated by the above image.

• Seafloor Methane - Another huge dangers is that all this additional heat will reach the seafloor of the Arctic Ocean and will trigger destabilization of methane hydrates contained in sediments at the seafloor. Stronger winds can mix warmer water all the way down to the seafloor, and destabilize hydrates that can contain huge amounts of methane, resulting in release of huge quantities of methane into the atmosphere.

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

http://arctic-news.blogspot.com/2017/06/high-waves-set-to-batter-arctic-ocean.html

Agelbert NOTE: The battered ocean racer sail boats I recently posted on provide evidence of even larger waves than those predicted in this post. The problem continues to grow while our leaders pretend there is no problem...

Agelbert NOTE: Here the biological logic of closing the high seas to fishing (Dr. Lubchenco calls it the Wet West - referring to the "Wild West" term because anything goes and there is ZERO respect for sustainability) is mentioned, although also pointed out by Dr. Lubchenco is the fact that major governmetns refuse to do so. 

As Economist P. Dasgupta laments, collective action to stop, or even ameliorate, this crisis consistently fails to be achieved, even though we are basically out of time for additional delays.
