Climate Change Act

Luciana Berger Excerpts

Tuesday 10th September 2013 Westminster Hall

[David T. C. Davies]

My hon. Friend is absolutely correct.

[Luciana Berger (Liverpool, Wavertree) (Lab/Co-op)]

I thank the hon. Gentleman for very kindly giving way so early in his speech. I know that I will have some minutes to speak at the end of the debate, but I want to ask him this question now. Why does he believe that 97% of more than 4,000 peer-reviewed studies by climate scientists over the past two years agree, first, that climate change is happening, and secondly, that it is man-made?

[David T. C. Davies]

First, as I have just said, climate change is happening, just as it has always happened. Secondly, we must consider the nature of what has been suggested is going on. Carbon dioxide is a warming gas—that is a scientific fact. There has been an increase in carbon dioxide in the atmosphere since we started industrialising—that is also a fact. Where I beg to differ is that it is not proven that the carbon dioxide that has gone into the atmosphere is responsible for the relatively small amount of warming that has taken place since industrialisation. The total amount of warming that we are talking about is some 0.8° C; it is a very small amount in the scheme of things.

When we started to industrialise, we were coming out of a very cool period known as the little ice age; it was so cold that the Thames used to freeze over and they used to have ice fairs on it. That is part of a pattern of cooling and warming that has been going on for several thousand years. We had a warm period during Roman times, and things became cooler again during the dark ages before becoming warmer during the mediaeval warm period. The temperature then became cooler before it started warming up again.

Some of the 0.8° rise has to be down to the fact that we were going to warm up whatever happened, because we were coming out of a cool period. Is the hon. Lady able to tell me how much of that 0.8° rise is a result of the natural warming that should have taken place? Perhaps she could also tell me why we cannot make a straightforward correlation between CO₂ emissions and temperature. If she is right, as the amount of CO₂ going into the atmosphere increases, temperatures ought to increase, but that is not what happened at all. We have seen increases and decreases. Temperatures went up in the first half of the last century, but after the second world war, as we industrialised and started to pour much larger amounts of CO₂ into the atmosphere, temperatures went down again until, in the 1970s, everyone was predicting a forthcoming ice age. Temperatures then started to increase again until about 1997. Since then there has been absolutely no increase in temperature whatsoever, and that is with all the industrialisation going on in China and India.

Perhaps the hon. Lady can tell us—

[Luciana Berger (Liverpool, Wavertree) (Lab/Co-op)]

It is a pleasure, as always, to serve under your chairmanship, Ms Clark. This has been a very revealing debate on a very important topic. Let me begin by congratulating the hon. Member for Monmouth (David T. C. Davies) on securing it, although I disagree with everything that he has said this afternoon. I am grateful for the opportunity to place on the record the Opposition’s position.

I am very proud to be speaking today in support of the Climate Change Act 2008, which was seminal legislation. Passing the first legally binding climate change target showed that Britain was serious about tackling one of the greatest challenges if not the greatest challenge that humanity has ever faced. Like my hon. Friend the Member for Brent North (Barry Gardiner), I am proud to belong to a party that took action to secure our planet for future generations when we were in government. I am prouder that Parliament passed the Act all but unanimously, with just five Members voting against it. I note that some of those five are in the room with us today. There was a clear cross-party political consensus that something needed to be done and a clear will to get on and do it, so I am saddened by the tone of parts of today’s debate. It reminds me of a film that was released just a few months after the 2008 Act became law. Many people in this room may have seen it. It was called “The Age of Stupid”. The plot is set in 2055 in a world savaged by the effects of global warming. It focuses on a lead character looking back to the beginning of the 21st century and wondering why we did not combat climate change when we had the chance. I am not sure whether the producers are planning a sequel, but at times I have felt as though certain speakers that we have heard today have been auditioning for a starring role. It is very disappointing that the hon. Member for Monmouth, who introduced the debate, is on record as describing the overwhelming scientific evidence and agreement on climate change as “codswallop”.

Let me spell out some basic facts; we have heard them reiterated by some Members taking part in the debate today. One hon. Member talked about an apparent plateau in world temperatures, but he neglected to mention the fact that the 12 warmest years on record have all come in the last 15 years. Since 2000, the UK has experienced its seven warmest years. Our average annual temperature has increased by about 1° Celsius since 1970. Last year, temperatures in some parts of our oceans were the highest ever and Arctic ice retreated to its smallest size on record.

I think that the Met Office is an organisation to be respected and I look at its reports very closely. Its record of global average surface temperature shows an increase of 0.6° C since 1950. I did not have an opportunity to intervene at the time, but there is research, including that published in Nature Geoscience in 2011, that shows that three quarters of the rise in average global temperatures since the 1950s is due to human activity.

A number of hon. Members referred to the UN Intergovernmental Panel on Climate Change, which is to deliver its fifth assessment report. As my hon. Friend the Member for Southampton, Test (Dr Whitehead) said, it is expected to report a 95% probability that the global warming that we have experienced since 1950 is man-made. I agree with my hon. Friend that we should take note of that report. It is compiled by 255 experts from 38 countries. The weight of evidence is extraordinary, so I am disappointed that that has not been reflected in some Members’ contributions this afternoon.

Back in 2008, the year in which the Climate Change Act was passed, the then Leader of the Opposition, who is now the Prime Minister, promised:

“We are not going to drop the environmental agenda in an economic downturn.”

He said that it was

“not ‘green’ or ‘growth’, but both.”

In the same year, the current Chancellor of the Exchequer talked about the “fierce urgency of now” and promised that the Treasury would lead in

“developing the low carbon economy and financing a green recovery.”

I could not agree more with the statements made then by those right hon. Members.

If we fast-forward to now, I regret the fact that the Chancellor is presenting us with a false choice between tackling climate change and growing our economy and that one Energy Minister—not the one in front of us, but the other Minister of State—has described climate change as a matter of “theology”.

I think that we need to deal with some of the risks. The fact is that the impact of climate change is already threatening to put more people in harm’s way up and down our country and across our planet. The Foreign Secretary’s climate adviser has described the security threat alone as being as grave as the threat from terrorism and cyber-attacks.

Let us take one example—flood defences. According to experts at the university of Colorado, sea levels are already rising at more than 3 mm a year. Just last week, a new study by the Met Office—I reinforce the fact that I respect that organisation; I do not think that it is putting out propaganda—showed that climate change exacerbated half the extreme weather events that happened last year. That has huge implications for us here in the UK and particularly for our flood defences. Last year was Britain’s second wettest year on record. Insurers had to pay out on £1.2 billion-worth of claims for flood damage across the country. Currently, 370,000 homes in England and Wales are at significant risk of river or coastal flooding. According to the “UK Climate Change Risk Assessment”, that number could increase fourfold by the 2050s.

[David Mowat]

The hon. Lady’s analysis would be completely correct if, by our reducing our carbon emissions, there would be that effect on our own climate. The difficulty that we have is that the rest of the world does not appear to have the same analysis as she does—at least judged by their actions, if not their words.

[Luciana Berger]

I thank the hon. Gentleman for that intervention. In a moment, I will show that countries across the globe do think that there is a problem and are investing massively—investing more than we are. That is all the more reason for us to come together with other countries at the future Paris COP—the conference of the parties to the UN framework convention on climate change—to secure that global climate change agreement. It is not that we should be doing it in isolation. Of course other countries should be doing it too, but that does not mean that we should not be doing it.

Let us consider what the opportunity is for a low-carbon economy. I am not sure what report the hon. Member for East Antrim (Sammy Wilson) was referring to. I referred to the CBI, which has estimated that of the little economic growth that we did have last year, more than one third of it came from green businesses. As my hon. Friend the Member for Brent North highlighted, the low-carbon sector was responsible for 25% of the growth in our economy last year. The view of the CBI is very clearly articulated. It has said:

“For UK business, climate change is no longer a threat to be feared, but an opportunity to grow the economy and lead the world”.

We know that the competition is fierce. If we take the decisions that we need to now, the UK can still get ahead of the curve. We can create a new kind of economy, create huge numbers of jobs and secure our energy future. But if we do not—if we delay—we risk being left behind. Again, I refer to what other countries are doing. In fact, the hon. Member for Warrington South (David Mowat), in his remarks, talked about evidence. In America, the investment has increased by 155%. In China, it is up by 63% and, contrary to the examples put forward—I listened to the right hon. Member for Hitchin and Harpenden (Mr Lilley)—China is also proposing a cap on its carbon emissions for the first time. If we continue to lag behind, we risk becoming more heavily dependent on single imported sources of energy that come at a higher price.

I am conscious that I have only a minute left. Delivering a green economy is about not just seizing opportunities but managing the risks. The hon. Member for East Antrim talked about scare stories. I would ask him to talk to America’s first climate change refugees—the hundreds of people who have been forced to flee the Alaskan village of Kivalina before it disappears underwater.

I shall conclude with this thought. Contrary to what the hon. Member for Monmouth has said, there are countless reasons why it is right, sensible and in our best interests to acknowledge the gravity of climate change and to acknowledge that it is man-made and that we should commit to tackling it sooner rather than later. The Climate Change Act 2008 provides us with a clear framework for doing just that. The Government now need to push on with achieving those targets, not hold back, because a plan is only any use if we keep to it.

Aside from the practical case, something more basic is at stake. I visit many schools in my constituency and have many conversations with children. It is clear that they understand the issue. We have a responsibility to hand over our planet to future generations in the same state in which we found it. There is not only a practical and financial case for action, but a moral case, for our children, our grandchildren and their grandchildren. It would be selfish to do anything else.
