Methane 'plumes' in the Arctic, positive feedbacks - and why we all need to act on climate changeRead Now
Jake Campton, UWE
""Dense plumes of methane over a thousand meters wide" have been discovered leaking from the permafrost around northern Russia following continued warming in the region - and the rate of release has been accelerating. Why does this matter? Methane is a potent greenhouse gas with 20 times the warming potential (heat-retaining ability in the atmosphere) of carbon dioxide.
That makes it extremely problematic. The total amount of methane beneath the Arctic is calculated to be greater than the overall quantity of carbon locked up in global coal reserves, meaning a planetary time bomb is currently ticking in northern latitudes. It is not only the scale of these outflows that is unprecedented; it is also the alarming frequency at which they are occurring. Dr. Semiletov’s research team that made the discovery found hundreds of these plumes, similar in scale, over “a relatively small area”.
Our planet’s weather has been thrown into disarray in recent years; the last decade has witnessed more weather records broken than the entire last century! The more we continue to heat the Earth, the quicker the permafrost will melt, increasing the rate methane can escape its icy prison; a positive feedback effect (Arctic ice is not the only one either, there are a lot in action - see this page for info on a few others). We will eventually become locked in by this effect, with heating leading to more rapid heating, accelerating the whole process further still. Add in the reduced albedo effect from the rapidly receding glaciers of Greenland and surrounding area and the danger we are in becomes clear.
We are in trouble. It doesn't take too much time reading up on climate science - as described in a World Bank report just out - to work that out. What's more, it's not just an issue for the polar bears; it's a health issue too. Humans are reliant on the environment and most critically, a stable climate to provide food; it doesn't magically appear on our supermarket shelves (even if that's what many kids now seem to think!) The last few years have seen intense droughts ravage vast swathes of the planet, including the major grain producing nations: Russia, Australia and the U.S. among others.
By mid-2012, the U.S only held enough grain for just 21 days. The increased scarcity of its staple crops caused sharp price spikes too - corn reached $8.39 a bushel by August 2012, an all-time record. Farmers were forced to cull large numbers of livestock as they suddenly became too expensive to feed. Are these the sorts of trends we should expect to continue looking forward? Grains becoming so expensive that meat is affordable only for the richest? And what about the poorest nations? What will the implications for malnutrition and food security be if the main exporting nations are unable to meet export demands? In 8 out of 13 recent annual harvests, global consumption has exceeded production, eating away at our grain buffers. A few more volatile growing seasons, and we could all be in real trouble. No nation is safe from a perturbed Gaia…
I blame a lot of people for this current mess. Not enough people care. That fatalistic idea, 'I'm one person, nothing I does matters' is, frankly, crap. 65 million UK inhabitants doing their bit, and I don't mean just recycling here, would make a substantial difference. If we were also to factor in 700 million Europeans and 300 million+ Americans - not to mention a billion plus Chinese and others - you can see the potential for drastic, meaningful, global change.
You see, you are not just one person; you are every environmentalist that plays their part in this conundrum. You are hundreds of millions of people. That is where our power to change lies; in sheer numbers. Industry is changing, albeit reluctantly, now society must change, too. My biggest fear is that most people won't act. It's a failure of our education system, a neglect of our moral responsibility - and it could be a catastrophe for humanity.
I realise we have had many decades of industrial pollution before us, but they weren't aware of the implications of their actions - and they were also far fewer in number, each consuming much less. If current trends continue, things could become truly and irreversibly messed up within a couple of decades and that terrifies me. It will be this generation and our immediate predecessors, the ones that peered into the precipice, who will be blamed. We could still make a meaningful impact on the current situation but I worry that we won't. We could have a great future ahead of us, but many forget that humanity and the environment are inherently intertwined. Until we recognise Earth as the delicate, dynamic and precious entity that she is, and treat her with the respect she requires, we will continue unabated along this perilous path. The bridge is out up ahead, we need to change paths.
I sometimes worry that the window for action has already closed, it’s something I feel bitter about, something that angers me greatly. There are people out there who are particularly responsible, who keep ignoring the problem, and their negligence is literally costing the Earth. I believe that if more people shared my sense of impending danger more would get done. I’m not sorry if this offends you, it's probably because you are the sort of person I am referring to. If my words are intrusive in to your way of life, maybe your way of life is part of the problem. When something so big is at stake, I think you have to ruffle a few feathers - feel free to comment if you wish to discuss anything further, I’ll gladly respond.
I know its complex, and it can feel like whatever you do is a drop in the ocean -sometimes it's difficult not to feel frustrated and concerned - but there is lots you can do. Start off by educating yourself; there's a lot of information out there - but always be critical. Outspoken anti-climate behemoths like the Koch brothers, use political and monetary leverage to fund anti-climate change ‘research’ and spokespeople to help maintain the status quo for their incredibly irresponsible and selfish gains. Be wary…
Are you a carbon addict? Take the test...
Below are some ways I try to reduce my impact on the environment. They're small steps that don't require much effort - why not give some of them a go?
Eating less meat - I can't understand why people assume it's a right and a necessity to eat meat every day, but this is one of the most effective ways you can reduce your burden, as well as making yourself healthier in the long run. We have molars for a reason; we are omnivores, not carnivores. Cycling and walking wherever you can is another great step - driving a few miles down the road is a missed opportunity to stay fit, a pointless waste of petrol and needless emission of carbon. I realise some people can't - fair enough, but most could. I bike everywhere, I feel great because of it and I’m very fit as a by-product.
You could shower instead of filling a bath, turn off plug sockets at the wall to avoid appliances ‘ghosting’ electricity, wash your hands with cold water instead of hot to save energy, boil the exact water you need when making tea, by cloth bags for shopping trips and avoid plastic, use LED light bulbs; expensive but they can last over 30 years and use just 10% of the electricity of halogen/filament bulbs! Wear an extra jumper instead of cranking up the heating in colder times, turn down the brightness on your laptop to reduce energy consumption and there are many more. These may sound like small things, but, when added up and multiplied by the efforts of millions of others, cumulatively, we can drastically reduce our strain on Earth and preserve the environment for future generations, as is our responsibility.
Things you do in your daily life matter, and - imperceptibly - help start to shift the norm. However, we need political change too, and contacting your MP and MEP, signing petitions or even getting involved or setting up local campaigns isn't actually as hard as it can seem - Google is your friend here.
Anyway, rant over - you're all free to act as you see fit of course, but what I'd really like to say, and excuse my French, is that you personally don't screw it up for future generations because you can't be bothered to act responsibly.
Acting together, we have a chance to change our future for the better. There’s no I in team, but there is in humanity. Share yours.
