Expected changes in Antarctic wind patterns may speed up global sea level rise, threatening coastal cities and low-lying countries around the world, a new study has warned.
Climate scientists have already resigned to the fact that sea levels, driven by melting ice sheets and glaciers around the world, will rise. It will mean that entire countries will eventually be lost to the sea.
However, now it is feared that coastal winds, which are thought to be strengthening because of a hole in the ozone layer above Antarctica, may rapidly speed up this process.
“When we first saw the results it was quite a shock. It was one of the few cases where I hoped the science was wrong,” said study lead author Paul Spence, of the ARC Centre of Excellence for Climate System Science.
Spence and his colleagues from the Australian National University and the University of New South Wales are the first team to factor these changing winds into Antarctic climate models.
Troublingly, they found the changing currents would push water up to 4C warmer than current temperatures to meet the base of exposed Antarctic ice shelves.
“This relatively warm water provides a huge reservoir of melt potential right near the grounding lines of ice shelves around Antarctica,” Spence explained.
“It could lead to a massive increase in the rate of ice sheet melt, with direct consequences for global sea level rise.”
The Intergovernmental Panel on Climate Change (IPCC) has warned that global sea levels could rise by between 26 and 82 centimetres (0.85-2.7ft) by the end of the century if stronger efforts are not made to curb climate change.
However, scientists were forced to reconsider this forecast, after more recent studies confirmed the irreversible collapse of the West Antarctic ice sheet has already begun.
This process means that potentially devastating eventual sea levels rise of up to 4 metres (13ft) is guaranteed. It was estimated that the process would take between 200 and 500 years, but now this prediction may have to be revised also.
Axel Timmerman, Professor of oceanography at University of Hawaii and an IPCC lead author who was not involved in the new Australian study, added, “It is very plausible that the mechanism revealed by this research will push parts of the West Antarctic Ice Sheet beyond a point of no return.
“This work suggests the Antarctic ice sheets may be less stable to future climate change than previously assumed.”
Small island states that are doomed to ‘drown’, as the impacts of climate change take hold, have been forced to resort to desperate measures. Kiribati recently purchased 20 sq km of land on Vanua Levu, a nearby Fijian island, to eventually relocate its people.
“If you were buying land in Australia and wanting to pass it down to your kids or your grandchildren, I suggest it’s a couple of metres above sea level,” Paul Spence added.

Environmentally Sustainable Furniture for Dummies
We probably don’t think a great deal about our furniture choices. I know that I tend to just buy whatever looks pretty, seems functional and fits my budget. That usually means a trip to a few showrooms and big warehouse stores, like Ikea.
But we have a responsibility to the planet. We can do better. There are three major ways that our furniture can help the environment:
- Purchase used and/or recycled furniture and extends the lifecycle of precious materials.
- Source furniture that is free of environmentally unsustainable products.
- Choose furniture that doesn’t require electricity – opting for manual transitioning.
By investing in environmentally sustainable, high-qualify furniture, you’ll be able to pass down items from generation to generation. This will save your heirs on the cost of furnishing their own home, and help to protect the environment from wasteful fad furniture that only lasts a season or two.
Natural and Recycled Furniture Materials
If you absolutely love the look of wood furniture, search for environmentally sustainable products. For example, locally sourced wood or bamboo can easily be replenished without requiring excessive international harvesting of precious woods that harm the environment.
Sustainable wood products are only sourced from companies and locations that have the ability to quickly replace harvested wood – providing a responsible resource for generations of manufacturers and consumers.
Recycled furniture can either be a gently used item from someone else’s home, or a new piece of furniture that’s been used from reclaimed sources. You’ve probably seen examples of this at your local park – cities are increasingly using recycled materials to create benches and picnic tables.
But recycled materials don’t have to feel rough or rustic. Items made from recycled wood are readily available for order online or in-store. And believe it or not, electronic waste can be reclaimed and crafted into beautiful pieces of modern furniture.
The only limitation on recycled furniture design is the imagination of the creator. If you want to do it yourself, check out this DIY recycled furniture pinterest board!
Avoid Harsh Chemicals that Harm the Environment
Did you know that many cushions are made of highly-flammable polyurethane? Furniture manufacturers help keep our butts out of the hot seat by treating the materials in cushions with fire-retardant toxins. Unfortunately this padding breaks down overtime and the dust is both toxic to humans and the environment.
There are multiple lines of eco-friendly furniture that avoid the use of flammable polyurethane – often substituting with organic cotton. Just understand that you’re going to be in for a bit of sticker shock – eco-friendly furniture, when purchased new from major brands, gets pricey.
If you can’t afford the pricetag, I recommend finding used furniture from the same product line. There are a ton of websites dedicated to helping eco-friendly consumers find used organic, responsibly sourced products – and that includes furniture.
You’ll also want to stay away from faux leather. Furniture made from pleather and other leather substitutes are heavily treated with chemicals. That’s never a win.
Hypo-allergenic stuffing, combine with traditional leather might be a decent compromise if you have to have the leather look to tie a room together. But be conscious of the fact that tanning is not an environmentally friendly process, so try to limit these materials in your design.
In conclusion, it’s up to you how crazy you want to go. I think that as long as you stay with used furniture, you’re on the right track – even if it isn’t environmentally perfect, it’s at least a sunk cost for the environment – the damage has been done and you’re extending its useful life. But I think the most important takeaway here is buy quality items that you can pass down to your next generation – if that means spending more on higher quality new items that are sustainably sourced, so be it.
Livery Services: Mother Nature Needs You to Invest in an Eco-Friendly Fleet
In the United Kingdom, fleet vehicles make up most of the traffic traveling our roadways. If there’s one area of the transportation sector environmentalists should be focusing on, it’s the way we move goods, services and people around the empire.
Businesses that operate a fleet of vehicles need to realize the environmental impact of their service, and the opportunities available to help them lower their operating costs, while saving mother nature.
A green fleet is much cheaper to operate – both because of lower petrol consumption and government grants and tax benefits.
Let’s take a closer look at the things your company is unnecessarily spending money on every year due to an old, dirty fleet of polluters.
Vehicle Taxes on Polluters vs. Environmentally Friendly Fleets
If you want to operate your commercial van on public roads, you’re going to have to pay a VED, or Vehicle Excise Duty. The total fee assessed for this is based on the age of your vehicle, not how much you drive it. This is important, because an idle fleet of polluters can be just as costly as a fleet of green vehicles that produce value for your company.
Vans that were built after 1 March 2001 were taxed either £132 every six months, or £240 annually. This rate is effective per the TC39 VED tax code. There are exceptions to this rate.
For example, if your van is classified as a Euro 4 van, and was manufactured between 1 March 2003 and 31 December 2006, TC36 VED tax code applies to you. The six-month rate is £77, or £140 annually.
For older vans, manufactured prior to 1 March 2001, your tax rate is based on the size of the engine. Vans with engines less than 1549cc are charged £82.50 every six months, or £150 annually. Old vans with larger engines must pay £134.75 every six months, or £245 annually.
Euro 4 vans are the cheapest to operate from a tax perspective. Why? Because they were fitted with specialized filters that help to reduce the amount of dangerous pollutants that make it into earth’s atmosphere. You enjoy the tax savings year-after-year by operating these vehicles.
It really is economically more affordable to operate a green fleet.
Petrol Costs – Another Reason to Think Green to Save Green
The cost of petrol is heavily impacted by our environment. When Britain is thrashed by stormy weather due to global warming, or oil production is impacted by environmental disasters, the cost of filling up skyrockets.
At the time of this writing, petrol is £1.16 per liter, and diesel is £1.18 per liter. There are forecasts from reliable agencies that see the price continuing to rise in the near future, passing price points not seen since 2014.
Regardless of the speculative nature of future fuel prices, the fact remains that vehicles that use less fuel save their operators money every time the wheels turn.
As an alternative, many companies are heavily investigating and testing all-electric and hybrid alternatives for a greener, more economical fleet. As an example, the Nissan Leaf is one of the most popular all-electric vehicles – and it’s a fantastic choice for transporting people or smaller cargo payloads to residential destinations. The total cost to charge a Nissan Leaf, using current electrical vehicle charging technology, is just £3.64 to go from empty to full charge.
That’s a HUGE savings over filling a petrol tank. And with the prevalence of fast-charge locations, it’s possible to go from zero to empty in just 30 minutes.
In conclusion, there are many ways to save on fleet operation costs. And by investing in a more efficient fleet, you’ll be doing your part to save the environment. Both tax incentives and lower operating costs make green fleets a no-brainier for serious fleet operators throughout the United Kingdom.
