The Heat on Hot

Having lived in a tropical country that knows warm almost all-year round, I’d surmise that the 34° Celsius indicated on the Yahoo temperature widget on my desktop makes this a typical almost-summer day. Scientists have pegged the temperature of a ‘normal’ room as anywhere between 23° and 25°, but 34° Celsius only makes me head to the malls more often for their excellent air-conditioning. I know for a fact that the temperature of a “normal” human body is 37° Celsius, but I still, however, think that 34° Celsius is just warm. It really does not cause me to panic. I know warm like the back of my hand.

Even if I have personally witnessed some very fierce typhoons, nasty flash floods, and the effects of the El NiƱo phenomenon, I just take them as hazards of the tropics. Besides, I have come to fully agree that flash floods in the urban areas of my country are caused by the clogging of waterways by garbage, and in the provinces by the denudation of forests by illegal loggers and weakening of the soil leading to erosion by indiscriminate and greedy mining companies.

NASA and the National Research Council report, “For the time period from 1979-1998, it is estimated that on average, over the globe, surface temperature has increased by 0.25 to 0.4 degrees C and lower to mid-tropospheric temperature has increased by 0.0 to 0.2 degrees C.”

Scientists claim that the layer of the atmosphere called “lower troposphere” or that which extends from the surface to about 5 miles up high would be warming at a slightly faster rate than the surface. NASA scientists warn that the earth’s temperature is dangerously high, and continues on an uphill climb.

The global temperature average in 2007 was 14.73° Celsius, the second warmest year on record. This is a mere 0.03° Celsius behind the 2005 maximum. January 2007 was the hottest January ever measured with a full 0.23° Celsius warmer than the previous record. August was also a record for that month, with September as the second warmest September recorded. The eight warmest years on record all occurred in the last decade.

Data maintained by NASA’s Goddard Institute for Space Studies reveal the rising pattern of global average temperature: 14.02° Celsius in the 1970s, 14.26° Celsius in the 1980s, and 14.40° Celsius in the 1990s. In the first eight years of the 21st century, the world averaged 14.64° Celsius.

Upwards of this current earth temperature, these things will occur according to the National Geographic Channel blog:

At plus 1° Celsius, hurricanes may hit the South Atlantic, rising tides could submerge the land around the Bay of Bengal, and new deserts could form in the western half of the United States.

At plus 2° Celsius, Canada’s melting tundra will give way to forests, insects may change their migration directions, the Pacific islands of Tuvalu may sink beneath the rising ocean tides, and majority of the world’s tropical coral reefs will die.

At plus 3° Celsius, repeated cycles of drought and fire may occur in the Amazon rain forest and release the carbon stored there, the snowcaps on the Alps will disappear, the Mediterranean and parts of Europe will experience terrible summer heat, superstorms and Category 6 hurricanes will occur, and thousands of species worldwide would face extinction.

At plus 4° Celsius, oceans will continue to rise and devastate countries like Bangladesh and Egypt, and cities like Venice could be totally submerged.

At plus 5° Celsius, the tens of millions of climate refugees will fight over extremely scarce resources resulting in worldwide strife.

At plus 6° Celsius, the world could resemble the Cretaceous Era, more deserts will dot the planet, natural disasters become common events, and the world’s great cities could be flooded or abandoned.

All these may sound like doomsday scenario, true. But, fact is, global temperature has risen by 0.33° Celsius since 1990. If we do not halt the rise in temperature, we can only calculate when the abovementioned scenarios will happen.

Let’s do some Math.

While it is true that not even thousands of cars can match the gases emitted by a single volcano, we have to agree that we expedited the condition behind the buzzphrase. Anyone who hasn’t added to greenhouse gases, raise your hand.

The good news is that there is still time to undo, in this lifetime, what we have done.

For starters, do the Math.

'Tis a Mad, Mad (Troubled) World!

Fired up by earnest concern, downright zeal, sheer creativity, desperation, confusion, or a whole slew of mental and emotional states, some folks have come up with ideas and put out remedies to the malady that ails planet Earth. Some of the initiatives may be downright wacky, still some a bit impractical. But, hey, they’ve made a step towards solving the woes of this one and only planet we call our own – something not all of us can actually claim to have done.









“Bitublocks” are construction materials made out of junk and waste such as recycled glass, sewage sludge, and incinerator ash. Invented by an engineer at the University of Leeds in England, the refuse with which these materials are made are kept from ending up at landfills. On the other hand, some scientists want to make more environmentally-friendly plastics out of chicken feathers.

Somewhere in Los Angeles, some employees keep a plastic bin of wriggly worms that they feed with their leftover sandwich crusts and apple cores, which the worms turn into compost.

Because carbon dioxide builds up in the atmosphere and warms the Earth, some scientists have proposed to capture plant emissions, compress them, and bury the carbon underground.

China wants to do away with what it calls “white pollution,” or those ubiquitous plastic bags that carry all and sundry, because they clog city street drainage and waterways. Australia wants to eliminate incandescent bulbs, thereby helping reduce greenhouse emissions.

Some scientists have proposed to put a ring of sunlight-scattering particles or micro-spacecraft in orbit around the equator. The ring which could cost trillions of moolah will reduce the amount of solar radiation and cool the planet a bit from greenhouse gases. Think Wayfarers on a beach bum.

Alternatively, some scientists have suggested injecting sulfur into the atmosphere to counteract global warming, in the hope that it could have the same cooling effect that occurs after a sulfur-spewing volcano erupts. Of course, we will need tons and tons of sulfur to do that regularly, as well as expect a lot of acid rain.

There is a suggestion by some people in the know to fertilize parts of the ocean with iron. Iron accelerates phytoplankton growth. Huge plankton blooms will use more carbon dioxide to make food. All the better to make those planktons happy since we have an excess of carbon dioxide.

Some of these ideas may sound zany to you but, most definitely, not to those who conjured them up. Let’s leave them to their insightful concepts. We have some thinking to do on our own, too.

Let’s start to make at least one step towards the solution of the problem. And we’ll do that today, won’t we? If you walk, instead of drive, you will help reduce carbon dioxide emission. The planktons will not be happy for it, but surely they’re already giddy with delight over the glut in CO2. You might also want to consider limiting meat in your meals this week. The meat industry is responsible for 18 percent of global greenhouse gas emissions through fertilizer use, animal manure, and the energy required transporting food and meat, so says the United Nations Food and Agriculture Organization.

You may not opt to use “sewage bricks” for your dream home but you can carry your next batch of groceries in a reusable cloth bag. And if you find putting giant sunglasses on earth an out-and-out madcap suggestion, you may simply choose to replace your broken incandescent bulb with a more cost-saving compact fluorescent bulb.

The call is yours. And we’ll take crazy ideas, too, if you have some.
