Auckland Diocesan Synod 2019

Synod 2019 starts next week and St Andrews Pukekohe is represented in four of the eight Motions to be presented.

Jan Wallace is seconding two Motions, one on getting the Seasons program operating in more parishes, the other on pushing the Diocese to do more around Climate Change Actions.

Vicky Mee is also seconding two motions, one on the Diocese taking a stance on improving housing for the elderly, the other on the preparation of a Diocesan Zero Carbon Plan.
For me, I am moving the Motion for Council to prepare a Diocesan Zero Carbon Plan and had a hand in writing the Climate Change Action Motion.  These are subjects that are important to me.

So why would we want the Diocese to prepare plans around climate change?

To me, there are two prime reasons.  

One is about resilience in the wider Anglican community.  Even though we do not yet have a firm idea of their form, significant climate-induced changes are coming and if no one is planning to meet the challenges of those changes, then we will have failed our Church community.  

The other is about social justice, the justice of the burden of climate change being carried by those who have contributed the least to the drivers of global warming that have led to climate change.

Is there a role for our Church to play in these two aspects?  What do you think?

Climate Action Q&A #5

and this Little Piggy went Wee Wee Wee, all the way home.

Q: Little Piggy’s home is in Wellington. Do you think it is better for Little Piggy to go there by car, plane or train?

——

Which means of transport has the least impact on climate change.

A: Driving a petrol car, Little Piggy would put 127 Kg Carbon Dioxide* in to the atmosphere. That is a lot more than flying (71 kg**). Taking the bus would be better, (44 Kg***) and the train better again (25 Kg****).

But driving a battery electric vehicle is the best for cherishing our earth – only 15 Kg of carbon dioxide*****.

Something to remember when you think about buying a new electric vehicle – there is a lot of carbon embedded in the car before you drive it out of the showroom. How many kilometres of do you need to drive before the embedded carbon is recovered in savings per kilometre? This is called the carbon payback distance.

For a Nissan Leaf, that is 8,000 Km – less than a year’s driving for most of us. A Tesla however, has a carbon payback period of around 35,000 Km – perhaps 3 – 4 years of driving.


Based on MfE emissions factor (EF) data and:
* Road distance Auckland – Wellington is 639 km, EF (petrol) = 0.1984 KG CO2/Km
** Air distance Auckland – Wellington is 480 km, EF (petrol) = 0.1474 KG CO2/Km
*** Bus distance Auckland – Wellington is 666 km, EF (petrol) = 0.066 KG CO2/Km
**** Train distance Auckland – Wellington is 682 km, EF (petrol) = 0.036 KG CO2/Km
***** Road distance Auckland – Wellington is 639 km, EF (battery EV) = 0.024 KG CO2/Km

Climate Action Q&A #4

This Little Piggy had none…

Q: What impact do the foods we eat have on our climate?

——

A: Plenty.  And we need to do something about that.

The global average carbon footprint for beef is 26.6 Kg CO2/Kg beef. New Zealand’s pasture-based beef has a footprint less than half of this. Compare this to crayfish with a carbon footprint of 27.8 Kg CO2/Kg fish or sole at 20.8 Kg CO2/Kg fish.

By the time your beef gets to the kitchen bench, it’s carbon footprint is typically three times that of the production on farms.  Making farmers accountable for all of beef’s off-farm emissions is not what a just transition needs to be about.

The solution is a localised food production system focused on organic, seasonal and fresh foods that include some meat but mainly vegetable.

Also, did you know that taking dairy out of our diet and replacing the minerals and nutrients with alternatives, results in the same or only slightly lowered carbon footprint?


Growing Your Own Food is something that each of us can do as a climate action.  St Andrews Anglican Church have a community learning and demonstration garden and offer a Grow Your Own Food course for beginners.

Climate Action Q&A #3

This Little Piggy had roast beef…

Q: Is eating beef bad for the planet?

——

A: The short answer is no, eating beef is not bad for the planet.

Reducing our beef consumption would be good for our health, but New Zealand beef is better for the planet than beef grown in other parts of the world.

The problem that needs fixing is with how some farmers grow their beef.

Also, we need to consider that around two thirds of the carbon in that steak on our plate, is from off-farm activities – the butchering, packaging and distribution.

Climate Action Q&A #2

This Little Piggy stayed home…

Q: How can we take carbon out of the atmosphere?

——

A:  If Little Piggy stayed home to plant trees and make biochar, then a lot of carbon dioxide would be taken out of the atmosphere each year.

That would be around 3,200,000 tonnes of carbon dioxide*** removed from the atmosphere by 2030 if each of us planted one hardwood tree today.

BTW: if Little Piggy planted native trees instead of exotic hardwoods,
then much less carbon would be removed (around four fifths or
80% less*** than exotic hardwoods).

And if each person burned ten kilogram of dry wood to make biochar, we would remove around 50,000 tonnes of carbon dioxide+++ from the atmosphere.

2017-ETS-look-up-tables-guide-3.pdf http://www.mpi.govt.nz/growing-and-producing/forestry/forestry-in-the-emissions-trading-scheme/emissions-returns/

+++ own calculation: 27% (by weight) biochar yield from dry timber (at 20% moisture content) and 1 kg C == 3.667 Kg CO2.

Climate Action Q&A #1

This Little Piggy went to market…

Q: How fast should Little Piggy go when driving to the market?

——

Plot of CO2 emissions at actual speeds compared to those at 100 kph

A: No faster than 80 Km per hour.

For each one kilometre we travel at 10 kph below our open road speed limit (of 100 kph), we avoid dumping around 0.03 KG of CO2 emissions to the atmosphere.   

That does not sound very much, but with 3.8 million light vehicles*** in the New Zealand fleet travelling at total of 22,208 million km at open road speeds***, that represents a total of 651 KT CO2/year, or around 4.4% of the transport sector emissions.  Step the speed reduction up to 20kph, the emissions reductions would total 1,220 KT CO2/year which equates to around 8.2% of the transport emissions.

Join us for Earth Day 2018 in Buckland

The future of the Earth as we know it, is under threat.  Scientists have named that threat global warming.

We already see some of the impacts of global warming: climate change; extreme weather events; the loss of animal and plant species; rising sea levels; and the acidification of our oceans.

The main drivers of global warming are twofold. First, the mining and burning of fossil fuels adds greenhouse gases to the atmosphere.  Second, when we cut down forests, we reduce the Earth’s ability to tolerate those gases.

To reduce the impacts of climate change, two things we must do.  One is to significantly reduce our individual and household greenhouse gas emissions.  The other is to remove carbon from the atmosphere.

The longer we take to do these two things, the harder is the task of ensuring a liveable climate for future generations.

EARTH DAY 2018, is the day to show that we cherish our Earth, the day to take a personal climate action to help ensure the Earth’s regeneration and protection for future generations.

Next Sunday, April 22nd, the Anglican’s Climate Action Network are offering an easy-do climate action that anyone can take.  The Pukekohe Anglican Parish are holding their second Charcoal Fire event in the grounds of St Paul’s Anglican Church in Buckland Road, Pukekohe.

For each person attending, a 1kg wood block will be burned to make biochar which will be buried in the soil and fruit trees planted on top.

This will reduce greenhouse gas emissions by avoiding the CO2 that would have been released back to the atmosphere as the wood decays.

It will also sequester1kg of atmospheric carbon dioxide.

And even more carbon will be removed from the atmosphere over the fruit trees’ lifetime.

Join us between 9 am and 11 am to place 1kg of wood on the fire and learn about biochar.

Or join us at 11:30 am for a sausage sizzle before the fire is quenched at 12:30 followed by the planting of fruit trees on the biochar.

The Charcoal Fire event 2018

A climate action that worked

World-wide, thousands of people took part in the March for Science on Earth Day last Saturday.  The Guardian‘s headline declared “Global ‘March for Science’ protests call for action on climate change” as the reason for the marches.   Calls to action and defending scientists from attacks on the legitimacy of climate science, were the objectives.
First celebrated in 1970, Earth Day events are held to demonstrate support for environmental protection.  The wider goals of this demonstration are laudable, but I have two ‘howevers’ around the March for Science action.
First is the irony of the marches – significant volumes of new carbon were emitted to the atmosphere from the vehicles used by participants.
Using the average emissions factor defined by our Environment Ministry for petrol vehicles and an average distance travelled of 25km, each participant released around 6kg of new carbon dioxide.
The second ‘however’ is that actions, not more words are now needed if global warming is to not exceed 2°C.  That is the goal of the climate agreement that our government has committed to.
One of the few Earth Day events that actually achieved a reduction in atmospheric carbon dioxide (CO2) levels, was the Charcoal Fire event at St Andrews Anglican Church in Pukekohe last Sunday.
This event involved burning wood to make biochar.  The char was buried, inoculated  and two peach trees planted on top.
For each person attending that event, an estimated 3kg of carbon dioxide was removed from the atmosphere and buried away for a very long time.  Plus the new trees will sequester more carbon for many years.
It may be that the Marches for Science had an impact on US politicians.  It is clear that the Pukekohe event had an impact on reducing global warming.

How does the carbon cycle work?
The carbon cycle is the movement of carbon between the atmosphere, oceans, soils, and plants.  
One part of that cycle involves trees and plants taking carbon dioxide (CO2) out of the atmosphere and converting it to carbon which becomes embedded within the tree, and to oxygen which is released back to the atmosphere.
When a plant dies naturally, much of it’s carbon is released back to the atmosphere, and becomes available to other plants to absorb and continue the cycle.
Soil contains one of nature’s largest stores of carbon which is slowly released to the atmosphere or locked away as fossil fuels.
This balance in the carbon cycle has been a feature of our environment for millennia. 
We humans upset that balance when we add new carbon to the atmosphere by tilling the soil, extracting and burning fossil fuels, and when we cut down forests.  We have been doing this for over 100 years, which is seen in the ‘hockey stick’ graph that charts rising atmospheric CO2 levels.

A win win win climate action

Last week’s cyclone-determined weather was mild for us in Pukekohe, but severe on our east coast and catastrophic further south in the Bay of Plenty.

It is likely that a future cyclone will deal equally severe blows to us and our west coast communities.

Whilst we cannot forecast severe weather impacts for specific areas, NIWA have warned North Islanders to brace themselves for more flooding events.

And scientists are finding more linkages between our carbon emissions and extreme weather events.  Last month, Nature.com published an article on the influence of anthropogenic – aka “human caused” – climate change on extreme weather events.

Are we, individually and collectively, prepared to take a punt on future catastrophic weather events bypassing us?  The people of Edgecumbe would give a different answer to that question from those not yet seriously affected.

Those who do not consider the risks are burying their heads in ever-warming sands, for one thing is clear: extreme weather events are now part of our future.

The Insurance Council agrees.  It was reported last week, that the Insurance Council and Local Government NZ have worked together for about three years to explore changes to building consenting processes.  Their goal is to minimise property damage during severe weather events.

But Prime Minister Bill English does not agree.  He was reported last week as saying that it does not matter “too much”, what is causing the weather we have experienced over the past three weeks.  He went on to say that climate change as the cause, is something he does not want to spend time thinking about.

It is our grandchildren’s future that he dismisses so casually.

So what can we as individuals do that our government do not want to think about?

One action is to reduce our household carbon emissions.  Which means travelling less, buying only what we need, reducing waste, saving energy and more.

The Charcoal Fire - A climate action.page1.jpgAn easy-do action, is for us to take carbon out of the atmosphere.

Atmospheric carbon now exceeds 400 parts per million, and to bring that back to a level that will keep global warming below 2°C, carbon needs to be removed from the atmosphere.

At The Charcoal Fire event on Sunday 23rd April, you can learn the means to achieve that.

Making and burying biochar is a win for carbon sequestration and a win for the fertility and water holding capacity of our garden soils.

And planting fruit trees on top of that biochar is a further win for growing healthy, nutritious food.

Join us at 18 Wesley Street in Pukekohe, anytime between 8 am and 11 am this Sunday (23rd April) to learn how to make biochar as a win win win climate action.

This climate action helps save the world

“Flash flooding is expected across the upper North Island over the next two days” trumpeted the news headlines last Tuesday morning.

What, again?  This is the third or fourth time this autumn that gutters and drains needed to be cleared of leaves in preparation for a deluge.

There was a time, not too long ago, that such flood warnings were issued for only “1 in 100” year events.

“1 in 100” does not mean that it occurs only once every 100 years.  It means that there is a one per cent chance of such an event occurring in a single year. Statistically, a 1 in 100 year event may occur many times in one year, but the average over a number of years, will be one.

It is wishful thinking to conclude that the next 500 years will therefore, be flood-free.

Given the clear impact that our carbon emissions have on global warming, we can expect only more extreme weather.

This may be why we no longer hear warnings of 1 in 100 year events.  The climate is changing so fast, that scientists have not been able to reassess their frequency.

One thing that science is getting better at, is the attribution of extreme weather events to man-made causes.

The World Weather Attribution Project is a collaborative project with Climate Central that aims to achieve near real-time attribution of extreme weather events around the world.

This week’s deluge, which should clear the country today, was described by a NIWA meteorologist as a “tropical torrent” and a “serious situation … arising in New Zealand.”

NIWA goes on to say that April, only six days old, is shaping up to be an abnormally wet month.  Five time the monthly rainfall was expected to fall in the last couple of days, with more heavy rainfall events expected.

So the Franklin ward, and Hauraki and Thames-Coromandel districts, should expect more damage from storms like that earlier in March that was declared a medium-scale adverse event.

How many times do we need “adverse events” to be declared before we realise that we need to take serious action on climate change?

Repeatedly clearing drains and gutters only normalises the situation.

The actions we must take must be focused on the dual fronts of reducing our carbon emissions, and on clawing atmospheric carbon back from our oceans and atmosphere.

A clear and strong climate action celebrating this year’s International Earth Day is planned for St Andrews Anglican Church in Pukekohe on Sunday April 24th.   Biochar will be created and trees planted at “The Charcoal Fire” event.  Join us – bring a gold coin or one kilogram of dry wood for burning anytime between 8:00 and 11:00 am.
