Human-driven climate change poses a great threat, unprecedented in type and scale, to well-being, health and perhaps even to human survival,” write three of the contributors to the IPCC report’s health chapter.
Writing for Australia’s the Conversation, professors Colin Butler and Helen Louise Berry, and Emeritus professor Anthony McMichael say the focus has been largely on “spurious debate about the basic science and on the risks to property, iconic species and ecosystems, jobs, the GDP and the economics of taking action versus taking our chances.”
Missing from the discussion is the threat climate change poses to Earth’s life-support system – from declines in regional food yields, freshwater shortage, damage to settlements from extreme weather events and loss of habitable, especially coastal, land. The list goes on: changes in infectious disease patterns and the mental health consequences of trauma, loss, displacement and resource conflict.

I am a “blue dot” member.
A “blue dot” movement has taken the Twittersphere and Facebook by storm. Photographs of Indigenous people with a blue dot on their chest are being posted on social media.
It follows what happened at a joint announcement on the First Nations Control of First Nations Education Act (FNEA).
The proposed legislation was announced in the Kainai First Nation on the Blood Tribe Reserve in Alberta. Prime Minister Stephen Harper, Assembly of First Nations National Chief Shawn Atleo and Aboriginal Affairs Minister Bernard Valcourt held a ceremony in the community to “seal the deal.”

Cookie-cutter solutions for F.N. education won’t work
Social media responds to the new F.N. Education Act
First Nations education funding still does not provide equality
Twila Singer and her two children attended the event.
Historical photos like this one of the American Indian Movement are showing up with blue dots. Christi Belcourt is using old photos of vocal figures to make a point with the blue dot campaign. (@christibelcourt/Twitter)
“We were separated at the door and given either a blue dot or a yellow dot. The blue dots were uninvited guests and were ushered to the gymnasium, and the invited guests were the yellow dots and they were brought to the auditorium where the dignitaries were.”

We often assume that Wall Street investment bankers represent everything that is anti-environment. The truth is, all investment bankers care about is money. In many cases, this drives them to support corporate loopholes and industry practices that put the environment at risk, but not always. In 2012, Goldman Sachs surprised the world by announcing $40 billion in clean energy investments. And just a few months ago, Goldman Sachs said that the renewable energy sector is one of the most compelling and attractive markets. Now they’ve gone a step further. According to the firm’s recent report, not only is solar power a good investment, it’s also poised to make fossil fuels obsolete:

After rapping through some of the energy issues we’re facing — the high cost of current oil production methods, the ridiculous talking points around the Keystone XL, and pollution from coal power plants (highlighting China) — the rapping crew takes a very brief look at Elon Musk’s electric vehicle and solar solutions (but with the main focus being that he is on Mars dressed like Iron Man), then gives a satirical presentation of Richard Branson’s asteroid mining plans.

Had we addressed the problem from the outset, we could have solutions in place. We could have found ways to burn less fossil fuel without massively disrupting our economies and ways of life. But we’ve become addicted to the lavish benefits that fossil fuels have offered, and the wealth and power they’ve provided to industrialists and governments. And so there’s been a concerted effort to stall or avoid corrective action, with industry paying front groups, “experts” and governments to deny or downplay the problem.
Now that climate change has become undeniable, with consequences getting worse daily, many experts are eyeing solutions. Some are touting massive technological fixes, such as dumping large amounts of iron filings into the seas to facilitate carbon absorption, pumping nutrient-rich cold waters from the ocean depths to the surface, building giant reflectors to bounce sunlight back into space and irrigating vast deserts.
But we’re still running up against those pesky unintended consequences.

According to a statement on the study from NASA, researchers developing warming estimates by calculating the Earth’s “transient climate response.” This measure determines how much global temperatures will change as carbon dioxide’s atmospheric presence grows at about 1 percent per year until the total amount of atmospheric carbon dioxide has doubled. Transient climate responses have range from near 2.52 degrees in recent research, to the Intergovernmental Panel on Climate Change’s (IPCC) estimate of 1.8 degrees. Shindell’s study estimates a transient climate response of 3.06 degrees. He says it is unlikely values would cool below 2.34 degrees.

His study also considers how aerosols, or airborne particles contribute to climate change in the Northern Hemisphere. Aerosols are produced by both natural sources like volcanoes and wildfires, as well as by manufacturing, driving automobiles, producing energy and more. Some aerosols cause warming, depending on their components, while some create a cooling effect. According to NASA, it is necessary to account for atmospheric aerosols in order to understand the role carbon dioxide emissions have on global warming.

A new study sponsored by Nasa’s Goddard Space Flight Center has highlighted the prospect that global industrial civilisation could collapse in coming decades due to unsustainable resource exploitation and increasingly unequal wealth distribution.
Noting that warnings of ‘collapse’ are often seen to be fringe or controversial, the study attempts to make sense of compelling historical data showing that “the process of rise-and-collapse is actually a recurrent cycle found throughout history.” Cases of severe civilisational disruption due to “precipitous collapse – often lasting centuries – have been quite common.”
The research project is based on a new cross-disciplinary ‘Human And Nature DYnamical’ (HANDY) model, led by applied mathematician Safa Motesharrei of the US National Science Foundation-supported National Socio-Environmental Synthesis Center, in association with a team of natural and social scientists. The study based on the HANDY model has been accepted for publication in the peer-reviewed Elsevier journal, Ecological Economics.
