For Filipinos who were born in the 50s and 60s (or born in the 70s and 80s), do you remember a song by Asin, "Masdan mo ang kapaligiran"? It was a famous song sometime in the 70s. Here's part of the lyrics:
...Ngunit masdan mo ang tubig sa dagat
Dati'y kulay asul ngayo'y naging itim...
Ang mga batang ngayon lang isinilang
May hangin pa kayang matitikman?
May mga puno pa kaya silang aakyatin
May mga ilog pa kayang lalanguyan?
Darating ang panahon mga ibong gala
Ay wala nang madadapuan
Masdan mo ang mga punong dati ay kay tatag
Ngayo'y namamatay dahil sa 'ting kalokohan.
Fast forward to today, about 30 years after that famous song...
-- ang dagat, kulay asul (blue) pa rin
-- ang mga batang 30s na ngayon, may hangin pa ring natitikman
-- may mga puno pa rin silang aakyatin (pero ayaw na umakyat, marami nang bondying na eh)
-- may mga ilog pa rin silang nalalanguyan (marikina river pwede pa, pasig river di na)
-- mga ibong gala, madami pa rin
-- mga puno, kalaban ng kuryente ng meralco kasi matataas ang dahon, fire and electrical hazards na.
lesson: climate alarmism in the 70s was proven wrong,.
climate alarmism of this decade is proven wrong in recent years up to the present.
Meanwhile, here's a short discussion about the effects of ocean decadal oscillations (pacific, atlantic) and cycles, and the Sun, on the world's climate. And some projections of what type of global cooling we are entering -- Dalton minimum type (2-3 decades cooling) or Maundeer Minimum type (7 decades cooling).
About El Nino and La Nina cycles, here's a good chart, from 1979 to 2009.
The problem with the alarmists is that they will insist that persistent cooling in the coming years is a result of "man-made climate change" and hence, all forms of environmental regulations such as carbon emission trading system (ETS) and other variants of carbon cap and trade, should be pursued at the global level.
