How many synonyms for “grim” can I pack into one article? I had to consult the thesaurus: ghastly, horrid, awful, shocking, grisly, gruesome.

This week, a big report from the UN’s Intergovernmental Panel on Climate Change was leaked before publication, and it confirmed, yet again, the grim—dire, frightful—reality the we face if we don’t slash our global greenhouse gas emissions, and slash them fast.

This “Synthesis Report,” to be released in November following a UN conference in Copenhagen, is still subject to revision. It is intended to summarize three previous UN climate publications and to “provide an integrated view” to the world’s governments of the risks they face from runaway carbon pollution, along with possible policy solutions.

As expected, the document contains a lot of what had already been reported after the three underpinning reports were released at global summits over the past year. It’s a long list of problems: sea level rise resulting in coastal flooding, crippling heat waves and multidecade droughts, torrential downpours, widespread food shortages, species extinction, pest outbreaks, economic damage, and exacerbated civil conflicts and poverty.

But in general, the 127-page leaked report provides starker language than the previous three, framing the crisis as a series of “irreversible” ecological and economic catastrophes that will occur if swift action is not taken.

Here are five particularly grim—depressing, distressing, upsetting, worrying, unpleasant—takeaways from the report.

1. Our efforts to combat climate change have been grossly inadequate.
The report says that anthropogenic (man-made) greenhouse gas emissions continued to increase from 1970 to 2010, at a pace that ramped up especially quickly between 2000 and 2010. That’s despite some regional action that has sought to limit emissions, including carbon-pricing schemes in Europe. We haven’t done enough, the United Nations says, and we’re already seeing the effects of inaction. “Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history,” the report says. “The climate changes that have already occurred have had widespread and consequential impacts on human and natural systems.”

2. Keeping global warming below the internationally agreed upon 3.6 degrees Fahrenheit (above preindustrial levels) is going to be very hard.
To keep warming below this limit, our emissions need to be slashed dramatically. But at current rates, we’ll pump enough greenhouse gas into the atmosphere to sail past that critical level within the next 20 to 30 years, according to the report. We need to emit half as much greenhouse gas for the remainder of this century as we’ve already emitted over the past 250 years. Put simply, that’s going to be difficult—especially when you consider the fact that global emissions are growing, not declining, every year. The report says that to keep temperature increases to 3.6 degrees Fahrenheit, deep emissions cuts of between 40 and 70 percent are needed between 2010 and 2050, with emissions “falling towards zero or below” by 2100.

3. We’ll probably see nearly ice-free summers in the Arctic Ocean before mid-century.
The report says that in every warming scenario it the scientists considered, we should expect to see year-round reductions in Arctic sea ice. By 2050, that will likely result in strings of years in which there is the near absence of sea ice in the summer, following a well-established trend. And then there’s Greenland, where glaciers have been retreating since the 1960s—increasingly so after 1993—because of man-made global warming. The report says we may already be facing a situation in which Greenland’s ice sheet will vanish over the next millennium, contributing up to 23 feet of sea level rise.

4. Dangerous sea level rise will very likely impact 70 percent of the world’s coastlines by the end of the century.
The report finds that by 2100, the devastating effects of sea level rise—including flooding, infrastructure damage, and coastal erosion—will impact the vast majority of the world’s coastlines. That’s not good: Half the world’s population lives within 37 miles of the sea, and three-quarters of all large cities are located on the coast, according to the United Nations. The sea has already risen significantly: From 1901 to 2010, global mean sea level rose by 0.62 feet.

5. Even if we act now, there’s a real risk of “abrupt and irreversible” changes.
The carbon released by burning fossil fuels will stay in the atmosphere and the seas for centuries to come, the report says, even if we completely stop emitting CO2 as soon as possible. That means it’s virtually certain that global mean sea level rise will continue for many centuries beyond 2100. Without strategies to reduce emissions, the world will see 7.2 degrees Fahrenheit of warming above preindustrial temperatures by the end of the century, condemning us to “substantial species extinction, global and regional food insecurity, [and] consequential constraints on common human activities.”

What’s more, the report indicates that without action, the effects of climate change could be irreversible: “Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems.”

Grim, indeed.

About kingstonrenewableenergy

Kingston Renewable Energy (KRE), Hydropower products, wind energy, renewable energy products, We manufacture, supply and install. Richard Kingston KRE is the home of Fluxy, a beautiful Irish made wind turbine designed to last several life-times, and a host of other Hydro products branded under KRE hydro. KRE HYDRO- KRE are currently installing a range of Hydro products including high head low flow systems and low head high flow. These are pelton and Turgo types for high head, crossflow Banki turbines for medium to low head and Powerpal for Ultra low head. We also plan to introduce a custom timber/steel/aluminium waterwheel service for those of you who are lucky enough to have disused mills on their land and who would like to restore them to their former glory (and make a healthy profit in the process). All hydro installations are custom designed. This is necessary because everybody's land and water resource is different and to benefit from the highest efficiency and lowest payback time the hydro system must be customized according to what flow, penstock length required, and what head is available. Hydropower is currently by far the most cost effective renewable resource in Ireland under the existing Feed in tariff structure and export rate of 9c per unit (wholesale rate for bigger systems is €0.087/kWh). It is surprising how much energy is to be harvested from even a small stream and we are offering 4 to 7 year payback times on average and high profits thereafter. KRE FLUXY- It has been a long journey from when I originally set out to buy a wind turbine to power my own house in 2007 and discovered that the existing machines on offer in the market failed to meet my desires as a customer; that is, to possess an aesthetically designed machine with a low embodied carbon footprint and a long design lifespan. This led to my resolve to make this a possibility as I knew there were other like minded folks out there who had the same needs when buying into renewable energy. I have always been a keen environmental activist and had a strong understanding of engineering and material sciences which enabled me to see failings in the high tech electronically controlled machines commonly available today. These weaknesses come from over complicating the wind system with servo motors, sensors, gear trains, relays and logic circuits; fine for large utility scale turbines which are constantly monitored and have continual maintenance on site but not for a small wind turbine in the back yard to run the house. I could see that wind turbines needed to be brought back to a less complicated yet modern design that would withstand time and the turbulent and violent winds we see in Ireland and fulfilling the old engineers adage of ‘KISS’ or ‘keep it simple stupid’. With less component parts, there are less things to go wrong. My vision was to create a machine that offered the benefits of being an economic investment, a positive for the environment and also to be a design piece that our customers are proud to have flying in their grounds. And so, I present you with the fully mechanical Kingston Renewable Energy Fluxy wind turbine. Please feel free to contact us at any time if you have any questions or think you may have a good wind site. We will happily do a site assessment come rain or shine. Stay posted for the monthly blogs from our inspirational team here at KRE. Check out our latest installments in our crusade to get higher feed-in tariffs in Ireland so that we can compete with the rest of Europe in the micro-generation stakes. The Hydro section of our website will be updated shortly to show our newest installations and showcase our products. Yours sincerely, Richard Kingston
