Along that pavement which has a narrow width, there are TWO rows of unshielded street lamps illuminating it for every few meters. The stray light was hitting almost all the way almost to the sea. The whole beach was much brighter when I visited it about a year or two ago with Gavin. What a pity considering the sky is still darker than most urban spots if one is facing the sea. Ironically, there are relatively darker spots around the hawker centre than the beach.

Hi Gary, I just saw your post this evening. Great report on your ob session at Changi Beach!

Sigh... looks like us astronomers are losing yet another site. I remember the serenity of that night at Changi beach during our Perseids watch in Aug 2011. I also sensed that the other people there fishing from the seashore were simply happy to enjoy the quiet darkness of the night. Whoever installed the lights there should at a minimum have used proper shielding, rather than flood the beach with light.

The fight against light pollution seems to be a losing battle around the world. And in Singapore in particular, the national motto seems to be, 'The Brighter the Better', rather than saving energy to keep carbon emissions down. It's purely lip-service to our global commitments. The one-day in the year Earth Hour lights down is I think a gimmick and a publicity stunt, making the organisation feel good about itself and disguised in the name of 'raising awareness'. For the other 364 days, it's a case of reverting to bad habits by flooding the buildings with more and more lights!

For example, every night I have to put up with the monstrous giant laser lightshow from the Marina Bay Sands casino complex visible from my window. I could understand it if it was once a week, e.g. Sat nights for the tourists, but it goes on and on every night.

And here comes 6.9 million...

I think it's too early to declare the victor in the fight against light pollution. Just tweeted this a few minutes ago:

"France Will Dim Its Lights to Conserve Energy"
http://www.nytimes.com/2013/01/31/world ... d=tw-share

From the energy-wasting and health point of view, the argument is very strong.

As for Singapore, I have not totally given up hope yet regarding light pollution, else I would have no more motivation to do sidewalks. That is also one of my reason for doing sidewalks at Toa Payoh Central with the crazy amount of light pollution - to prove a few important points which will be useful in the future to gather more public support to reduce the pollution.

The 6.9 million is actually a good wake up call for people who want to do their part in reducing the light pollution before its too late. It can be used positively as a rallying point.

Keeping quiet and moving further and further away from light-polluted spots is not helping the situation and those who do so only have themselves to blame for not doing their part to raise awareness.

We need to reach out to the proper authorities, interest groups and ultimately the general public which share our common goal. So stay tuned ... :)

Here are some of the composite photos by Thierry Cohen to inspire us to do more:

A very interesting development, and I applaud the city of Paris for it. However, such a thing won't happen in Singapore, trust me.

Here, the unrelenting policy is GDP growth, growth and ever more growth, regardless of whether it's desirable or sustainable. For example... 7 million tourist arrivals per year? Not good enough, we must target 12 million by Year X. How? We need not one, but two casino resorts, including one that shoots out those mega-lasers every night that despoils the natural night sky. And now that we've gotten 14 million tourist arrivals a year, it's still not good enough, see for example this article from last year:
"Singapore hopes to attract up to 10 per cent more visitors this year.
The Singapore Tourism Board (STB) has projected visitor arrivals to be between 13.5 and 14.5 million this year, an increase of up to 10 per cent from 2011.
From a low of S$12.6 billion in 2009, tourism receipts have more than doubled to S$22.2 billion in 2011.
The government will pump S$640 million to seed new tourism projects over five years.
Three new areas of growth have also been identified."
http://www.channelnewsasia.com/stories/ ... 71/1/.html

5.3 million residents in 700 sq km? Not good enough, we need 7 million in 17 yrs' time or else we won't be 'vibrant'. It really is a target, believe me. They are simply tone-deaf.

Business/economic interests here to keep all the lights running will certainly override any environmental concerns, and that's why I say what happened in Paris will never happen here. Microsoft will sooner adopt iOS than Singapore would do what Paris has done.

To put the relative mind-sets of the 2 countries in perspective, just consider what Singapore's carbon emissions pledge at the 2009 Copenhagen Summit actually was, notwitstanding the blind praise that was accorded it by the local mainstream media. Let's compare the pledges:
(see: http://en.wikipedia.org/wiki/2009_Unite ... _accord-22 )

European Union: To cut greenhouse gas emissions by 20% below 1990 levels by 2020 unconditionally. Member country Germany has offered to reduce its CO2 emissions by 40% below 1990 levels by 2020.

People's Republic of China: To cut CO2 emissions intensity by 40–45% below 2005 levels by 2020.

Japan: To cut greenhouse gas emissions by 25% below 1990 levels by 2020.

United States: To cut greenhouse gas emissions by 17% below 2005 levels by 2020, 42% by 2030 and 83% by 2050.

You would note that the above are all actual cuts, i.e. reductions in emissions down to a level that is lower than what it was previously. Not just below the levels that were existing during the Copenhagen Summit in 2009, but in some cases 20% below levels 20 years ago. Those amounted to huge cuts.

What was Singapore's pledge?
Singapore: To reduce emissions by 16% by 2020, based on business-as-usual levels.

Now that's cute. Because what Singapore said is that it would continue to grow and increase carbon emissions (See? 'growth'... and See? 'business') but the only sacrifice it is willing to make in the face of climate change would be to slow down the rate of growth such that by 2020, it would be lower than what it otherwise would have been. Put it another way, in 2009, Singapore said that by 2020, carbon emissions would be: (2009 levels + growth every year till 2020) minus 16 %. Thus by 2020, Singapore's carbon emissions would actually be higher than what they were in 2009, not lower.

Do you see the essential difference? It may be subtly different at first sight, but it's a world of a difference. To me, that was just a publicity stunt, and the ST lapped it up blindly (I remember, and I was incredulous). Are we proud of the sacrificies we as a nation was willing to make compared with the rest of the world, and as our pledge in exchange? Is that how we intend to 'save the environment', or just pay lip-service?

If you think it has been mis-stated in Wikipedia, see the following from an official webpage:
"Singapore announced, just before the UNFCCC Climate Change Conference in Copenhagen in 2009, a pledge to reduce our greenhouse gas emissions by 16% below Business-as-Usual (BAU) levels in 2020"
http://app.nccs.gov.sg/page.aspx?pageid=55

And to remove any doubt about my interpretation of what it meant, I've just done a Google search and found this:
"Singapore’s absolute carbon emissions in 2007 is about 40 million tonnes and from the statement above, it seems that the government projected that carbon emissions will reach 75 million tonnes in 2020 on a business-as-usual scenario. If Singapore takes action to reduce its emissions by 16%, the cut is equivalent to 12 million tonnes, meaning that emissions would reach 63 million tonnes in 2020. This cut is not based on 1990 or 2005 levels, it is just based on 2020 levels, which implies that there is no peak in emissions and a drop thereafter. What we would expect is a continuous increase in absolute carbon emissions till 2020."
http://www.asiaisgreen.com/2009/12/03/t ... au-levels/

So, from 40m tonnes of carbon emissions in 2007 to 63m tonnes in 2020 is a growth of 58%! Certainly not a reduction.

That's why we're probably the only country that had ever officially labelled a recession as an instance of "negative growth". I remember that too!

Nice research. Bookmarked. Useful stuff to build up the case in the future. Thanks. :)

I also remember a time when building platform screen doors on all elevated MRT stations was deemed impossible. :)

Hi,Starfinder
Yes,I think by 2030 our hobby will disappear because we will be so crowded that all buildings will be 30
storey and above.6.9 million is no joke.Even the trains will have to bring to the city centre,say 1 million
workers into our banking hub.;and say 1 mrt train can carry 5000(ie they remove ALL the seats and let all passenger stand only).That will require 200 trips.;but at
3 min per train,that will require--in 1 hr--20 trains.--in other words 10 mrt line going into the banking
hub to enable them not late for work.Light pollution--I think even the cemetry will be surrounded by
buildings and perhaps we have to go to northern malaysia to see the stars.Today generation dont
know how sweet potatoes are planted;well tomorrow generation will ask their father and mother
what are stars,etc.sad. [smilie=crying2.gif]

From now till 2030, there is about 17 years so anything can happen.

Thinking out loud, I have a few choices.

(1) I can keep complaining about light pollution in singastro for another 17 years.

(2) I can always hide in a dark corner when we are observing in Singapore and hope the general public will not come and "disturb" me for the next 17 years.

(3) I can be more pro-active in spreading our hobby and raising awareness of light pollution to the general public and authorities for the next 17 years.

If I choose option (1) or (2), do I even have the right to blame others for not understanding our situation and improving it?

I imagine I am in 2030 now.

My children/grandchildren ask me why they cannot see stars on a clear night and did I even bothered to make sincere attempts to improve the situation for the past 17 years. What will I say to them? "Oh, I did post something about it in singastro in 2013?"

I would like to add a few more points on a broader perspective on the matter.

I think we humans, at 7 billion and counting, are exhausting the Earth's resouces at an unsustainable rate. The stresses are manifesting itself in climate change. We're also taking too much from the Earth at the expense of other species, both flora and fauna. Their numbers and space (forests) are declining, and many species have been pushed by us to the verge of extinction, if not there already. This is quite selfish of us.

Perhaps the declining fertility rates in developed economies is a natural response to a situation, that tends to bring things back to a balance. Urban areas are crowded, urbanites are stressed and heavily worked, so people there stop or slow down in reproducing as a natural reaction.

If the native population in developed countries such as Japan and Singapore decline, then why not let it be? Why force and prop the population numbers up, by trying so hard to increase the fertility rate, and by immigration? I think that over time, as the population ages and numbers decline, fertility rates will naturally revert to the once higher levels, because space is created and there would be a general sense of a gap to fill. So the 'greying crisis' will resolve itself naturally.

In a similar vein, do we really need further economic growth, when we've already achieved developed status (to the govt's credit)? That's why I can't understand the desire, for example, to aim for even more tourist arrivals when we've got so many millions already and it's so overcrowded and cramped here. Why can't we be content with 14m tourist arrivals a year in a country just 700sq km in size?

Earth is at a stage where its countries' economies and population may need to stop growing, and perhaps even decline in size naturally. The need to reduce carbon emissions to prevent further climate change is a reflection of this: duty to our home the Earth and duty to future generations. We as a nation should not escape from our share of responsibility and duty. That's why I was very disappointed that at the Copenhagen Summit in 2009, we (Singapore) refused to make an actual reduction in our carbon emissions (which would have required some reduction in economic and industrial activity). This when we were already a developed country, so no excuses please.

And as for the current debate about our economy and our population, let me say this: I think that Singapore's economy is actually over-sized. We could not be having such high GDP numbers if the economic activity was not being artificially propped-up by foreign labour. We overshot the mark of growth goals which we legitmately aspired to when we were a developing country in the 1960s-1980s. We should have let our economy stop or slow down its growth in around 2000. Our population then could not sustain further growth as there was a 'manpower shortage' hindering further growth. The response was to drastically increase the population to enable more growth to take place. Growth was and is no. 1 national policy.

And this process is being repeated once more, hence the present announced plan to increase infrastructure further and reclaim even more land, so as to cater to a population of 7 million. Hello?

I think we not only need to stop growing the size of our economy, but even, and here's a controversial thought, perhaps we may want to gradually shrink it back down. Down to a level that's naturally sustainable by a population of 4m+ people. After all, there are only around 3.3 m citizens. Let it be.

And as for astronomy... with that managed, intelligent reduction, we can bring down light pollution too and appreciate the night sky.
