Climate change is with us 01 What is climate change?

To understand climate change, it’s important to recognise the difference between weather and climate. Weather is the variation of temperature, precipitation and wind, which change hour by hour and day by day. The climate is the average weather and its variations across decades. Climate change is the long-term change in climate and is usually used in the context of man-made climate change.

What is climate change? 05 The effects of climate change

Global warming will lead to hotter, drier UK summers and warmer, wetter winters. Some will welcome these warmer temperatures. Lifestyles and employment patterns will change and some industries will benefit from the opportunities these bring. The potential boost for UK tourism, for instance, could create more jobs throughout the country. Conversely, an increased reliance on refrigeration and air conditioning systems could bring added costs and contribute to further global warming; while the severity and impacts of recent heatwaves, and floods remind us of our vulnerability to extreme weather, even in developed countries.

06 The effects of climate change Extreme weather could be more frequent and dangerous. This may restrict imports of certain foods and other essential goods to the UK, boosting prices.

The severity of these effects will depend largely on the amount of greenhouse gases released into the atmosphere from now on, and how the climate responds. Global forecasts from the Met Office show the likely range of impacts we can expect:

+1°C

Some marine ecosystems suffer irreversible change. +2°C

The effects of climate change 09 The economic impacts The Stern Review on the Economics of Climate Change (pub. October 2006), to which we contributed, gives a comprehensive independent assessment of the economic impacts of our changing climate. It also shows how to deal with it through mitigation and adaptation, from an international perspective. Its main conclusion is that we need to invest 1% of global Gross Domestic Product (GDP) every year to mitigate the effects of climate change. Doing nothing could reduce global GDP by as much as 20%.

The economic impacts 13 What can you do?

The earlier action is taken on climate change, the more effective it will be. Evidence shows that ignoring climate change will eventually damage economic growth. Mitigation, though, is an investment to avoid the risks of very severe consequences in the future. If we invest wisely, the costs will be more manageable and there could be a wide range of opportunities for growth and development along the way.

14 What can you do? Did you know? The Department for Transport needs to change its infrastructure to avoid melting road surfaces, buckling railway lines and subsequent disruption in hot weather.

Planning now could mean profits later. Every organisation needs to ensure it has an in-depth understanding of the likely future impacts of climate change on its policies and business aims. Leading organisations in the climate change era will have made careful risk and opportunity assessments and adjusted the decisions made today to enable success tomorrow.

For instance, 2005 saw the coldest winter of a decade in Europe, while 2006 was the warmest year on record in the UK.

However, for many organisations the degree of certainty within the next few decades is sufficient to warrant taking detailed guidance and direction on climate change impacts from us. Those who take this first step will be better prepared for the range of climate change effects on their sector, region, or policy area.

We’re also working to reduce uncertainty by building in the best possible estimates of uncertainties in global and regional weather patterns, using advanced technology. As we discover more about climate change and options for mitigation and adaptation at local, regional and global level, we’ll equip you with the latest and best information.

How we can help

Here, at the Met Office, we offer some of the best climate change advice in the world. We play a major role in limiting the problem by continuing to study its causes and effects and by helping you understand the science behind mitigation and adaptation. The results of decisions to protect environments, societies, economies and businesses today may last decades or even centuries so it’s important that we work together to get it right.

As the cost of mitigating and adapting to climate change is so significant, central government and regional planners work with us to ensure that action taken is informed by the very best research and advice.

That’s why Defra and MoD have funded the Met Office Hadley Centre in a 5-year climate research programme which will deliver a stream of cutting- edge climate change science and advice. As our knowledge increases on the challenges and opportunities posed by our changing climate, we will further define our advice and direction on the investment required to inform your decisions.
