Temperature Rising in Cameron Highlands

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?”

The Sound of the Rain

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!”
