Is Global Warming natural or man-made?

Natural causes• Earth’s Orbit• Sunspot Activity• Volcanic Eruptions • Etc.

Reasonable agreement up to ~ 1960

Man-made causes do not show particularly good agreement in early part of period.

BUT including both man- made and natural gives good agreement

District 1080: Community Service & Vocations CommitteeIn 2010 we had one of the warmest ever January – February periods. Some people say surely it was coldest for 30 yearsBut why do people not account for the record breaking high

temperatures in the tropics, Australia etc?5th Warmest -

• Winter: October – March: • Summer: April to September• Compared to 1960 – in 2010,

– 13.1% less heating needed– And 106% more cooling.

District 1080 Assembly: Community Service & Vocations Committee

Temperature rise in East Anglia over last 50 years is unequivocal

Data to end of Oct 20102010 is on track to be 2nd warmest year (GLOBALLY) NASA data suggests it has chance of exceeding 1998

Do we want to exploit available renewables i.e onshore/offshore wind and biomass?.

Photovoltaics, tidal, wave are not options for next 20 years.

If our answer is NO

Do we want to see a renewal of nuclear power ?

Are we happy on this and the other attendant risks?

If our answer is NO

Do we want to return to using coal? •then carbon dioxide emissions will rise significantly

•unless we can develop carbon sequestration within 10 years UNLIKELY

If our answer to coal is NO

Do we want to leave things are they are and see continued exploitation of gas for both heating and electricity generation? >>>>>>

Our Choices: They are difficult

21

Our Choices: They are difficult

If our answer is YES

By 2020 • we will be dependent on GAS

for around 70% of our heating and electricity

imported from countries like Russia, Iran, Iraq, Libya, Algeria

Are we happy with this prospect? >>>>>>If not:

We need even more substantial cuts in energy use.

Or are we prepared to sacrifice our future to effects of Global Warming? - the North Norfolk Coal Field?

Do we wish to reconsider our stance on renewables?

Inaction or delays in decision making will lead us down the GAS option route and all the attendant Security issues that raises.

How many people know what 9 tonnes of CO2 looks like?

5 hot air balloons per person per year.

On average each person in UK causes the emission of 9 tonnes of CO2 each year.

"Nobody made a greater mistake

than he who did nothing because he thought he could do only a little."

Edmund Burke (1727 – 1797)

24

Raising Awareness

• A Toyota Corolla (1400cc): 1 party balloon every 60m.

• 10 gms of carbon dioxide has an equivalent volume of 1 party balloon.

• Standby on electrical appliances up to 20 - 150+ kWh a year - 7500 balloons. (up to £15 a year)

• A Mobile Phone charger: > 10 kWh per year ~ 500 balloons each year.

• Filling up with petrol (~£50 for a full tank – 40 litres) --------- 90 kg of CO2 (5% of one hot air balloon)

How far does one have to drive in a small family car (e.g. 1400 cc Toyota Corolla) to emit as much carbon dioxide as heating an old persons room for 1 hour?

1.6 miles

At Gao’an No 1 Primary School in Xuhui District, Shanghai

上海徐汇区高第一小学

• A tumble dryer uses 4 times as much energy as a washing machine. Using it 5 times a week will cost ~ £100 a year just for this appliance alone and emit over half a tonne of CO2.

• Social Attitudes have a profound effect on actual electricity consumption

• For a given size of household electricity consumption for appliances [NOT HEATING or HOT WATER or COOKING] can vary by as much as 9 times.

Data courtesy of Karla Alcantar

• Significant savings in money can arise from effective awareness raising

• When income levels are accounted for, variation is still 6 times

New Strategy: pilot lights off throughout summer and used strategically in winter resulted in an annual saving of:5400 kWh of gas; 1030 kg of CO2 ; and a monetary saving of £260Or a percentage saving of 38%

Ways to Respond to the Challenge: Technical Solutions: Solar Photovoltaic

Photovoltaic cells are expensive, but integration of ideas is needed.

Output depends on type but varies from ~70kWh to ~100kWh per square meter per year.

The New Feed In Tariff form April 1st will make things more attractive. 41p per unit generated – an extra 3p if exported.

But those who have installed PV will get the benefit from increased payments for electricity by those who have not.

• Which can spread the message• Engage with Schools• Dispel myths• Use simple messages that people understand - often monetary

values mean more• Think about our own actions.

– Tumble drying – once a week amounts to £25 a year• Can we car share when going to District Council?

– Four people travelled separately from North Norfolk to District 1080 Assembly. They would have emitted and extra 75kg CO2 extra compared to travelling together at a cost of £30 extra in fuel.

• Energy Security issues will be just as important as Carbon reduction in the UK.

• Energy Security will increasingly affect us in next 10 years• Global warming will increasingly affect our fellow citizens of the

planet in the developing world in the next 10 years• Addressing Energy Security by taking small steps now will also

help with Global Warming• Otherwise the Young will suffer during their life times.• We in Rotary have the resources to work with the Young to

combat the challenges facing us.

The Unbalanced Triangular Trade

Each person in Developed Countries has been responsible for an extra 463 kg of CO2 emissions in goods imported from China in just 3 years

Water issues are equally important.

Each tonne of steel imported from a developing country consumes ~ 40 - 50 tonnes of water

•Save paper & reduce landfill•Promotes Rotary•Raises funds for Foundation


Lao Tzu (604-531 BC) Chinese Artist and Taoist philosopher

“If you do not change direction, you may end up where you are heading.”

And Finally

• Engage with the Local Community / Schools?

– To promote awareness

– To Join together to get discounts on sustainable projects

• Share a remote reading meter around your club to help members/local community cut their energy consumption, improve energy security, cut carbon emissions and save money?

• Is there merit in organising a District Workshop on Environmental Issues? e.g.

– raising awareness where the individual can save money?

– Providing a sustainable and energy secure future for our children

– Engaging with the community to protect the environment.
