Tomorrow s climate predictions for a warming world

Tomorrow’s Climate…Predictions for a warming world

Dangerous climate change... It's important not to be alarmist but it is very important to be alarmed. (David Miliband, Defra, 2006)

Tomorrow s climate today s challenge climate change local energy solutions a brief introduction
Climate change: the greatest challenge to face man (Duke of Cornwall/Prince of Wales, BBC interview, October 2005)

We live not, in reality, on the summit of a solid earth but at the bottom of an ocean of air…. (Thales of Miletus (c.625 - 545 BC))

Tomorrow s climate today s challenge climate change local energy solutions a brief introduction

We're putting 70 million tonnes of pollution into the atmosphere every day, trapping an enormous amount of extra heat from the sun inside the earth's atmosphere. It's threatening to push the planet past a tipping point beyond which climate change would be difficult to stop. (Al Gore, 45th Vice President of the United States (September 2006)

Our new technologies, combined with our numbers, have made us collectively, a force of nature. (Al Gore, 45th Vice President of the United States, 'An Inconvenient Truth' (2006))

A blanket of gases traps the sun’s heat in… causing Global Warming


More GHG’s in the atmosphere = warmer world & climate extremes

Tomorrow s climate today s challenge climate change local energy solutions a brief introduction

So what have we caused? atmosphere every day,

There is more CO2 in the atmosphere now than there has been in the last 650,000 years… (382ppm CO2/430ppm CO2e rising at 2ppm+ p.a.)

11 out of the last 12 years have been the hottest years in recorded history…

The clearest evidence that we are living beyond environmental means is the threat of dangerous climate change. The scale of this threat, to human life and to the natural resources and assets on which it depends, for everything from oxygen and clean water to healthy soils and flood defence, means that this simply must be our top priority (David Miliband, Secretary of State for Environment, Food & Rural Affairs)


In 2003 35,000 people died across Europe as the direct result of the heatwave that summer…

By 2080 extreme summers like the 2003 heatwave will be common place…

Tomorrow s climate today s challenge climate change local energy solutions a brief introduction

A threat to our food and water supplies atmosphere every day,

The sea level in SW UK is projected to rise by 0.8m by 2080…

Globally about 100 million people live less than 1m above sea level…

The vast majority of glaciers have been retreating and thinning over the past 30 years…

Chinese Meteorological Administration predicts that China’s northwestern mountains will lose over a quarter of their current glacier coverage by 2050

These glaciers supply 15-20% of the water to over 20 million people in the Xinjiang and Qinghai Provinces alone…

In India 500 million people rely on the Indus and Ganges, which are largely feed by glacial meltwater…

What do we know about future climate change

Sub-oceanic Methane Hydrate releases

  • The remaining ice sheets are eventually eliminated from both poles.

  • Rainforests have burned up and disappeared.

  • Rising sea levels have inundated coastal cities and are beginning to penetrate far inland into continental interiors.

  • Humans are herded into shrinking zones of habitability by twin crises of drought and flood.

  • Inland areas see temperatures 10 or more degrees higher than now.

Today s challenge what can be done

Today’s Challenge! atmosphere every day,what can be done…

Tomorrow s climate today s challenge climate change local energy solutions a brief introduction

How? atmosphere every day,

1. Adaptation

2. Mitigation

Where do we start?

Education, education, education…

Education & capacity building must come first!

We need a new environmental consciousness on a global basis. To do this, we need to educate people…(Mikhail Gorbachev)

We need to develop the new green industrial revolution that develops the new technologies that can confront and overcome the challenge of climate change; and that above all can show us not that we can avoid changing our behaviour but we can change it in a way that is environmentally sustainable… (Tony Blair, 2004)

Key abatement strategies
Key abatement strategies atmosphere every day,

Economic measures required to address climate change:

  • Putting a realistic price on carbon

  • Supporting low carbon technologies

  • Removing barriers to uptake of sustainable energy

    Planning for energy descent will require main-streaming of:

  • Demand reduction & energy efficiency programmes

  • Structural change – Sustainable Resilience (new localism)

  • Low carbon technologies

Reducing your carbon footprint

Reducing your Carbon Footprint atmosphere every day,

Sustainable Energy

at home and in your community

Your basic carbon footprint
Your Basic Carbon Footprint atmosphere every day,

Measures your:

  • Household emissions

  • Workplace emissions

  • Transport emissions

  • Consumption emissions

    Today we’ll briefly deal with one of the primary ways of reducing the first 2 categories…

So what s wrong with our current energy system
So what’s wrong with our current energy system? atmosphere every day,

It’s massively inefficient… such that 68% of primary energy is wasted… & this leads to unnecessary CO2 emissions…

What are the experts saying about this
What are the experts saying about this? atmosphere every day,

In the early years of the new millennium, the electricity system, the bloodstream of industrial society, is going to change almost beyond recognition. It will have to.

(Walt Patterson - Royal Institute of International Affairs, UK)

The current power infrastructure is as compatible with the future as horse trails were to automobiles

(Kurt Yeager - President, Electric Power Research Institute)

So what s the alternative decentralised energy
So what’s the alternative? – Decentralised Energy! atmosphere every day,

Localisation of energy generation… power to the people… from the people

What does this look like:

So what does sustainable energy really mean
So what does Sustainable Energy really mean? atmosphere every day,

  • Energy Conservation: Conserving energy by being aware of you energy use – frugality

  • Energy Efficiency: Consuming the energy that you do use in the most efficient manner

  • Renewable/Low-Carbon Energy Sources: Capturing and using natural, renewable energy sources… whilst minimising the GHG emissions associated with the use of fossil energies.

What do i mean by energy conservation
What do I mean by Energy Conservation? atmosphere every day,

  • Turning your thermostat down by 1ºC could cut your heating bills by up to 10 per cent and save you around £40 per year.

  • Is your water too hot? Your cylinder thermostat shouldn't need to be set higher than 60ºC/140ºF.

  • Close your curtains at dusk to stop heat escaping through the windows.

  • Always turn off the lights when you leave a room.

  • Don't leave appliances on standby and remember not to leave appliances on charge unnecessarily.

  • If you're not filling up the washing machine, tumble dryer or dishwasher, use the half-load or economy programme.

  • Only boil as much water as you need (but remember to cover the elements if you're using an electric kettle).

  • A dripping hot water tap wastes energy and in one week wastes enough hot water to fill half a bath, so fix leaking taps and make sure they're fully turned off!

2 using the most energy efficient space and water heating equipment
2. Using the most Energy Efficient space and water heating equipment…

The efficiency of your heating system depends on:

Choosing the right fuel based on lifestyle/demand, availability, cost, and GHG emissions

Using the most efficient (i.e. A rated) appliances

Using the controls effectively, i.e. timers & zoning

Making sure heat loss is kept to a minimum

Choosing a your fuel

Standard bulbs can be replaced with Compact Florescent Lamps

Spot bulbs can be replaced by either CFLs or LEDS

Such bulbs generally cut your energy consumption between 4X and 20X

The time for action is now…

The costs of stabilising the climate are significant but manageable; delay would be dangerous and much more costly…

(Sir Nicholas Stern ‘The Stern Review’ 2006)

Community energy projects
Community Energy Projects equipment…

A recognised role for the community:

Energy White Paper (May 2007) states:

259 Community level organisations have the potential to play an important role in communicating climate change and in helping their communities make real and lasting changes to their day-to-day lives. … Initial findings by the Centre for Sustainable Energy and Community Development Exchange imply that effective community initiatives are likely to be a necessary component of a coherent national approach to tackling climate change.
