23th May 2016- When the replacement Local Plan for Cameron Highlands 2030 was open for public viewing late last year, many of us could not immediately find the time to scrutinize it . It came in 3 big volumes ie Jilid I to III and since no detailed copies were initially available for the public to ‘takeaway’, one had to spend time at the town planners office to study it. (Later, although it became available online some pages were duplicated while others were missing.)
Then the reporters started calling. Amongst the first questions they asked were “What is REACH’s comment on the 7.5 degrees rise in minimum temperature in Cameron Highlands?”
Summary of Weather in the Cameron Highlands – 2nd Edition By: Erica Jenkins (email@example.com)
There is a weather station in the Cameron Highlands at 1545 meters above sea level. This weather station has been collecting weather data since April 1983, including precipitation, temperature, wind speed, and evaporation. The following report summarizes these data.

Summary of Weather in the Cameron Highlands
By: Erica Jenkins (firstname.lastname@example.org)
There are two weather stations in the Cameron Highlands, one is located at 1472 meters above sea level; data from this station is available dating back to Janauary 1951. Another station is located at 1545 meters above sea level, and data from this station dates back to April 1983. The data collected at these stations includes precipitation, temperature, relative humidity, wind speed, and evaporation. The following report summarizes these data.
The location of our current weather station at Jalan Tengkolok ,Tanah Rata is known to many locals, so when the above signboard came up, many amongst us did not bat an eyelid. I certainly did not, despite passing by this notice almost daily as I commute between Tanah Rata and Brinchang. That is until a close friend told me its significance and I decided to google it. What I found was very interesting indeed.
Sometime in early 2008, a mast like structure was found in Rhododendron Hill in Tanah Rata which turned out to be an anemometer (device used to measure wind) mast. The feedback from some senior residents was that in the 1930’s a weather station was built there by the British to monitor the climate for the then budding tea industry. Parameters measured included wind and temperature.
In 1935 the Meteorological department built a weather station on the hill behind the main street of Tanah Rata at latitude 4”28’ North and 101” 23’ East and elevation of 1471 metres above sea level. Most of our earlier meteorological data were from this station which is operational till today. Initially it was used to measure basic climate monitoring parameters such as temperature, rainfall, wind direction and speed etc. In 2012 seismic ‘strong motion’ detectors were installed. To put it simply, if the ground beneath us in Cameron Highlands were to do the ‘shakes’ it would be able to detect it. This little station of ours has become an earthquake monitoring station.
In the earlier 1980’s most of the basic observations were shifted to a new station located at 4 “ 47’North and 101”37’ East at an elevation of 1545 MSL. This new site was chosen because it was a little further away from major developments and the surrounding areas pristine with acres upon acres of lush montane forest. The pristine nature of the environment would ensure more accurate climate readings and in 1989 this new station became a Baseline Global Atmospheric Watch GAW station. Subsequently in 2004 it became the Regional GAW station, a testament perhaps that our environment in these parts is relatively uncontaminated for now.
In 2008, following the signing of the Comprehensive Nuclear Test Ban Treaty and with the cooperation of the Malaysian Meteorological Department, the Malaysian Nuclear Agency and the Preparatory Commission for the Comprehensive Nuclear Test Ban Treaty Organisation CTBTO, this little station became a Radio nuclide monitoring station.Hence the above signboard.
(The Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans nuclear explosions by everyone, everywhere: on the Earth’s surface, in the atmosphere, underwater and underground. One hundred and eighty three countries have signed the Treaty, of which 163 have also ratified it (as of September 2014), including three of the nuclear weapon States: France, the Russian Federation and the United Kingdom. But 44 specific nuclear technology holder countries must sign and ratify before the CTBT can enter into force. Of these, eight are still missing: China, Egypt, India, Iran, Israel, North Korea, Pakistan and the USA. India, North Korea and Pakistan have yet to sign the CTBT. Since the Treaty is not yet in force, the organization is called the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) The Treaty has a unique and comprehensive verification regime to make sure that no nuclear explosion goes undetected
• Seismic: 50 primary and 120 auxiliary seismic stations monitor shockwaves in the Earth. The vast majority of these shockwaves – many thousands every year – are caused by earthquakes. But man-made explosions such as mine explosions or the announced North Korean nuclear tests in 2006, 2009 and 2013 are also detected.
• Hydroacoustic: 11 hydroacoustic stations “listen” for sound waves in the oceans. Sound waves from explosions can travel extremely far underwater.
• Infrasound: 60 stations on the surface can detect ultra-low frequency sound waves (inaudible to the human ear) that are emitted by large explosions.
• Radionuclide: 80 stations measure the atmosphere for radioactive particles; 40 of them also pick up noble gas. Only these measurements can give a clear indication as to whether an explosion detected by the other methods was actually nuclear or not. They are supported by 16 radionuclide laboratories.

For the average citizen in a peaceful country with no major nuclear energy industry and not under imminent threat of nuclear weapons, the prospect of being exposed to serious nuclear radiation seems very far off. But no country is an island. When the Fukushima nuclear leak occurred some years back, did the radionuclide particles reach the skies of Malaysia? If it did this little station would have been able to detect it.
There are only 80 such Radionuclide stations in the world and Malaysia and especially Cameron Highlands should be proud to be able to play a role (albeit a small one) in the banning of nuclear arms .It is therefore vital that the readings of this station be accurate and to ensure that, the surroundings must be fairly free from contamination especially from dust particles that could possibly emit some tiny radiation. However the state government seems to have fail to recognise this and developments have been approved adjacent to this station and more developments within 1 km radius of this station is being planned. What is the point then of showing to the world that we are serious about being part of the global community, but on the ground the opposite seems to be true when it comes to radionuclide monitoring and climate monitoring. For accurate readings we should stop all new developments around our weather station or else relocate it to an even more isolated area which is easier said than done.
In 2009 this station was further upgraded with the construction of a new 2 storey building. Now this pretty little building with state of the art climate monitoring equipment is in jeopardy because the slope bordering it has been excavated till it is very steep. How could it have reached this stage? Aren’t the Land Department Officers supposed to monitor this?
We don’t need to be slope engineers to know that the steeper a slope is, the greater are the chances of collapse. When this slope collapses our weather station may tumble down too. Incidentally this slope is less than 200 meters from the site of the landslide which killed 7 Orang Asli villages in Sungai Ruil on the 7th August 2011.
As this illustrates, the Federal and State Government should coordinate better to ensure a good outcome. It is really meaningless that while on one hand the Federal government is trying to comply with the conditions of the Comprehensive Nuclear Test Ban Treaty by setting up the Radionuclide Monitoring station, the development around the area will result in less than accurate readings, showing to the world perhaps that we are less than sincere in playing a part in nuclear monitoring.
To conclude the area around our weather stations at least within a 2 km radius should have minimal development, to ensure that radionuclide and climate monitoring remains accurate especially in this age of climate change and global warming.
20th-Aprl-2014-A few months ago, a video clip of Parliamentarians discussing the environmental impact of farming on the tourism industry made the rounds in Cameron Highlands cyberspace. For many locals, it was difficult to watch that even in the august House of Parliament , Cameron Highland’s problems were taken so lightly and discussions, shallow. One of the comments made was that Cameron Highlands is no longer cold.
So what exactly is the weather like in Cameron Highlands nowadays? Has it gone a little weird? Is it warmer, colder, wetter or drier? Are the changes partly due to the global warming phenomena or are they due to the loss of the buffering effect of our highland forests or a combination of both? Do we have any data to substantiate what we say about the local weather?
If the subject of law is difficult to comprehend, the subject of weather is more so for we have nature’s wrath and unpredictability to contend with.
Below is a simple interpretation of the raw weather data of Cameron Highlands which dates back more than 55 years ago and attempts to answer the common questions pertaining to the weather in Cameron Highlands
Q 1: Is Cameron Highlands getting warmer?
The data that we have compiled is from 2 weather stations. From 1965 to 1983 the data were from the station located at 1471m above sea level M.S.L. , 4˚28’N 101˚23’E while the subsequent years up to 2013 were from the 2nd weather station located at 1545 M.S.L,4˚28’N 101˚22’E. Strangely the temperatures recorded at the lower weather station were lower than the one at a higher elevation.
Referring to the chart below, at a glance Cameron Highlands appears to be getting less cold. The lowest minimum temperature has risen from around 10 degrees Celcius to 15 degrees Celcius while the average minimum temperature has also risen slightly.
To the locals (applicable to non smokers only) it means “ Dulu kadang kadang bila cakap , ada asap keluar dari mulut , sekarang tak adok” “ Previously sometimes when we talk, vapour comes out from our mouths, now there is none!”
Below are the raw data of number of raindays for Cameron Highlands from 1951 to 2001 at the same weather station ie Latitude 4:28’N Longitude 101:23’E, Elevation 1471m
