Careful future Earth Temperature Will Rise 5.2 Degrees Celsius

Friday, May 22, 2009
WASHINGTON, -This century, the impact of global warming could be twice the more severe than the estimated six years ago, some experts such a report this weekend. "Temperatures average surface increased 9.3 degrees Fahrenheit (5.2 degrees Celsius) until 2100," some scientists said the Massachusetts Institute of Technology (MIT), compared with the study plan in 2003 that the average temperature increased 4.3 degrees F (2.4 degrees C). Studying the new record in the American Journal of Climate Metrological Society's claims, the difference is caused in the projection example of increased economic and economic data more recent than the previous scenario. "Prior warning on climate change also may have covered the impact of various global cooling volcanoes XX century by filth and soot, which can increase warming," said the scientists in a statement. To have reached a decision, MIT team uses computer simulation that takes into account the world economic activity and the climate. "All these projects show that the action is fast and without large-scale, warning that dramatic will happen in this century," said the statement. Results will be seen much more severe when there is no real action, made in order to combat climate change, compared with previous projections. However, some changes will occur if strict policy is applied at this time also to reduce greenhouse gases out. "There is a greater risk than we previously estimated. And this shows that we must immediately take action as soon as possible emergency," says Ronald Prinn, co-author one of these. This study is broadcast during the U.S. President Barack Obama announced a plan to set out national standards for cars and trucks, to reduce global warming pollution. Design and making of the gas trading system set to cut greenhouse gases, which is discussed in the Committee of the Senate Energy and Trade.

The Planetary Air Leak


May 2009; Scientific American Magazine; by David C. Catling and Kevin J. Zahnle One of the most remarkable features of the solar system is the variety of planetary atmospheres. Earth and Venus are of comparable size and mass, yet the surface of Venus bakes at 460 degrees Celsius under an ocean of carbon dioxide that bears down with the weight of a kilometer of water. Callisto and Titanplanet-size moons of Jupiter and Saturn, respectivelyare nearly the same size, yet Titan has a nitrogen-rich atmosphere thicker than our own, whereas Callisto is essentially airless. What causes such extremes? If we knew, it would help explain why Earth teems with life while its planetary siblings appear to be dead. Knowing how atmospheres evolve is also essential to determining which planets beyond our solar system might be habitable. A planet can acquire a gaseous cloak in many ways: it can release vapors from its interior, it can capture volatile materials from comets and asteroids when they strike, and its gravity can pull in gases from interplanetary space. But planetary scientists have begun to appreciate that the escape of gases plays as big a role as the supply. Although Earths atmosphere may seem as permanent as the rocks, it gradually leaks back into space. The loss rate is currently tiny, only about three kilograms of hydrogen and 50 grams of helium (the two lightest gases) per second, but even that trickle can be significant over geologic time, and the rate was probably once much higher. As Benjamin Franklin wrote, A small leak can sink a great ship. The atmospheres of terrestrial planets and outer-planet satellites we see today are like the ruins of medieval castlesremnants of riches that have been subject to histories of plunder and decay. The atmospheres of smaller bodies are more like crude forts, poorly defended and extremely vulnerable.

Interview with SMAK 1 BPK Bandung principal



Friday 1st of May 2009
12:30 - 12:50
picture: is questioning with Ma'am Boni.





1. According to you, how the school's environment we are now with the issue of Global Warming?


SMAK 1 doesn't have more empty space to plant trees.


2. so, what that the best way we should do?


there are several ways:


  • sparing in the use of paper and plastic
  • sparing in the use of electricity (reducing the use of lights, and turning off the AC when not being used)
  • planting trees


3. What will schools do to prevent global warming?


school has been planning a program to plant 1,000 trees by 1000 people. besides, with the educational environment (PLH). Starting next year will also be undertaken by students a new rule: not allowed to bring food out of the food court area. hygiene school so that will be more awake to the good. There are also program the separation of organic and inorganic waste, but does not run properly because of lack of a sense of awareness of the students themselves.


4. I've heard about a program, planting 1000 trees, how is that program, is it going well?


this program is not running because of rushing between teachers and students. but this program will run if all of Smak 1 BPK citizens, buy plants together to be planted along the food court. besides, there are also programs beetwen classes to plant the trees, and the winner will be gifted by PLH team.


5. How does the solution to the school paper-recycling of paper / other documents?


Currently, the school recycling paper / other important document with crusher machine. remaining waste usually are being sold by employees and the money given to them


6. What is the role of schools about the environment in school?


The school had perfome program to plant trees in the civilian's residents around the school. This activity is the responsibility of the PLH team of SMAK 1. I hope this program can be continue.

Coral Reefs Could Absorb Carbon


Absorption of carbon (carbon sinks) in the process through the media assimilation possible coral reefs occur, especially in the area of Indonesia where the majority of its area consists of the sea. Researcher field Oceanography Indonesian Institute of Science Kurnaen Sumadiharga in Jakarta on Wednesday, said, the issue of absorption of carbon through the media coral reefs are to be used as the main discussion topic in the Conference or the World Marine World Ocean Conference (WOC) and Coral Triangle Initiative (CTI) in Manado, 11-14 May 2009. He explains, photosynthesis process may be done by the plants that have leaves or chlorophyll. According to him, coral reefs consist of elements from the animals called coral polyp that do mutualism symbiosis with plants, alga, the green seaweed. "This is the plant that indeed the process photosynthesis, even in the water," he said. Photosynthesis process, he said, require carbon dioxide (CO2) and sunlight, then produce oxygen (O2), water and sugar. The CO2 which is the main material photosynthesis process, he said, is also available in the sea. He said that, at night, while coral reefs do not assimilation, this plant would produce CO2. "Carbon is produced at night is what becomes the main material of a photosynthesis process," he said. Therefore, he continued, the existence of coral reefs should be maintained and utilized as well as possible to anticipate the occurrence of climate change. Deputy Assistant Damage Control of Marine and Coastal Conservation Improvement Deputy Natural Resources of the Ministry of the State Environmental Wahyu Indraningsih said, the existence of coral reefs in Indonesia should be strongly guarded. According to him, other than caused by the use of explosive materials, global climate change some time this is also one of the causes of damage to coral reefs. He says, result in climate change to increase sea-water temperature. "The temperature of sea water rose 2-3 degrees Celsius in two consecutive days caused damage to coral reefs," he said. Conditions such as this have also started in the area of Indonesia.
