The Debate: Should we be doing more to combat climate change?

Untitled 11 300x300 The Debate: Should we be doing more to combat climate change?Fifty years ago, few people cared about pollution, deforestation, whaling or the Ozone layer. But even with an increasing awareness of issues concerning the environment, there is still a long way to go.

This week The Independent is looking at the successes and failures of the Green Movement at 50, with a series of blogs and features centred around the question: “Has the environment movement been a success?”

Climate change has been an integral part to the modern discussion of environmentalism; cited as both paramount to our survival and scaremongering, and  the debate continues to evoke mixed responses as to what exactly needs to be done.

Tony Juniper argues that we must act to increase taxes on pollution and waste before the impact on our infrastructure is too severe, with Bjorn Lomborg asserting that the tested policies implemented have been futile with little positive outcome for the environment, which requires innovative green alternatives.

Which do you agree with?

Tony Juniper

Human civilisations emerged during a period when the Earth’s climate was unusually stable. Because of changes to the composition of the atmosphere that time is coming to an end. This is mainly due to the combustion of fossil fuels and deforestation.

Because of climate change the weather is becoming more extreme, less predictable and more volatile. This is in turn causing major stresses for our societies, for example in economically costly damage to infrastructure and social impacts linked to higher food prices and health problems. If we don’t act quickly these and other consequences of climate change could become unmanageable. But where should we focus in our search for solutions?

My view is that answers lie mainly in the domain of economics. The problem is big and broad, it requires the kind of fundamental shift in priorities that can only be delivered through price and cost signals. Fortunately we have quite a good box if tools with which to start building our response.

These include ways to price emissions via different kinds of carbon tax and trading schemes, international payments for countries that cut deforestation, reforms to increase taxes on pollution and waste (while cutting them on income), shifting the hundreds of billions of pounds-worth of subsidies away from encouraging fossil fuel use and instead spending that money on expanding sources of clean energy. These and other tools can be used to supercharge the powerful forces of innovation and markets, in the process creating jobs and growth.

Markets and inventiveness will not be enough on their own though. Despite gargantuan efforts by many technological entrepreneurs, very few have been able to break the economic stranglehold of those who thrive in the fools paradise where business-as-usual holds sway. We can be sure of this because the world has known about this problem for more than two decades and despite the many attempts to make change under prevailing economic conditions emissions in 2011 reached an historic high point.

Fiddling around with a few modest environmental rules, or hoping for the best with technology, will not be enough. If we are to get past this particular challenge then climate change must become a priority for big grown up economic policy.

Often, this question implies an indirect ambition: ‘Should more countries set more ambitious targets for cutting carbon at a faster rate?’ Then the answer is no. The current Kyoto-style approach has failed for 20 years, because substantial emissions cuts are very costly for people today, — but with few benefits .

Humanity utilizes fossil fuels because they power everything we like about civilization, from inexpensive food to warmth and transportation. Greater access to modern energy sources means higher living standards and more opportunities. And fossil fuels are generally still much cheaper than green alternatives.

At the same time, dramatic global carbon cuts would only produce a measurable impact on global temperature after 2050 (mid-century).

Thus, it is near impossible to ask countries to cut emissions with more expensive, less efficient and often intermittent green energy, with benefits accrued only in 100 years. Just look at the failed Kyoto treaty, the collapse of 2009 negotiations in Copenhagen, and the absence of any real progress since.

We need to find smarter policies. In the Copenhagen Consensus for Climate (fixtheclimate.com) 27 top climate economists and 3 Nobel Laureate economists found that every pound spent on Kyoto-style CO2 reductions would prevent as little as 2 pence worth of climate damage. In contrast,  investing in R&D into green energy would be 500 times more effective, avoiding 10 pounds of climate damage for every pound spent.

This is because innovation promises to reduce the price of future green technologies below the cost of fossil fuels. Then everyone would switch to green energy, not because of a Kyoto deal, but because the technology is cheaper.

So yes, we should do more to combat climate change, but not by repeating the same, failed policies of past decades. To reap the future reward of cheap, green energy, we need to ramp up investment in innovation.

    Thanks David. “All your people start dying”… Another snippet from Fox news!

    Reason and good science would suggest that those scientists who question the link between HIV and AIDS would be given a fair hearing, both in the interests of health and in the interests of perhaps fully dismissing their claims as wrong.
    If they’re so wrong… there’s nothing to be afraid of… is there?

    Your comments on the relationship between government and big pharma are simplistic and naïve. You have little understanding of the world you live in. Health is of no consequence and neither is the debt created to continue big parma’s ‘customer retention’ that you pay for through tax. “When a government is dependent upon bankers for money, they and not the leaders of the government control the situation, since the hand that gives is above the hand that takes. Money has no motherland; financiers are without patriotism and without decency; their sole object is gain.”
    ― Napoleon Bonaparte

    A recent interview with Professor Luc Montagnier in which he declares: “We can be exposed to HIV many times without being chronically infected. Our immune system will get rid of the virus within a few weeks.”
    These remarks come from the man who obtained the 2008 Nobel Prize in Medicine for his discovery, in 1983, of HIV, the so–called virus that causes AIDS.
    You are right David, this debate was about global warming, however you have not been honest enough to admit that the trend is one of cooling. You are also not honest enough to admit that CO2 statistics alone cannot explain global climate patterns as will be shortly realized when the models collapse.
    Perhaps one day we’ll find a subject that we agree on. Currently, we’ll have to agree to disagree.
    Good day to you.

    The global warming scare was based principally on the Vostok ice core data. It has since been shown that this data indicates historical CO2 levels to have risen AFTER warming took place, blowing a hole right through that theory. Meanwhile the ‘hockey stick’ was shown to have been based on data which gave wrong temperatures for the 20thC. Yet, this data was nevertheless assumed to be reliable in respect of earlier temperatures.

    Wood’s Experiment shows that there is in reality no such thing as a ‘greenhouse gas’ -Greenhouses warm due to trapped convection, the contribution from infrared-absorbing substances such as glass or carbon dioxide being negligible. We also know from basic math and from Koch’s Experiment that what little effect CO2 has on temperatures is logarithmic, thus it cannot produce any runaway effects.

    We know that clouds (which are not gaseous but liquid or ice droplets) have a profound effect both on incoming solar heat, and on surface heat loss at night. We also know that various mechanisms can influence the extent of cloud formation, most of which are not human-induced. These mechanisms are the most likely explanation for 20th Century climate changes.

    Perhaps most importantly, we now know that most of the proposed solutions to the ‘climate change problem’ are money-spinners for thier proponents, and worse, that these ’solutions’ are mostly a waste of money because they don’t live-up to claims made for them. Not only will they not prevent climate change, but they will not provide us with a reliable energy supply either. Worse still, some of these ’solutions’ will actually cause large amounts of pollution and environmental damage, as in the mining of rare earths for windturbine magnets, the tearing-up of hillsides for construction roads etc.
