夏洛姑娘轉載雅加達市區大水照片，引發成員對溫室效應的關懐，鮑伯、珍妮周一向對植物生態之関懷不餘遺力、泰米作為綠色啚書館志工亦大聲疾呼其圖書館引用滲水良好之paving 、土壤含水率為綠色建物指標之一。而蘿蔔感嘆生存受到威脅，乃経湯姆大叔首肯，整理一份相關資訊，

As Sharow passed over the photos, in which shown that Jarkata happened with serious flood yesterday, and the discussion regarding greenhouse effect phenomenon has been proceeded with. As considering the situation of environment is getting tougher for the grown up of carrot, some information about green house effect the application of permeable paving has been collected herewith after obtaining uncle Toms’ permission.

Tammy ever advised us the permeable paving has been used in front of Beitou Green Library during our visiting there. The soil water content is also one indicator of green buildings. Therefore, Tammy is also quite familiar with this issue.

Name origin- Greenhouse effect

The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way.

Incoming UV radiation easily passes through the glass walls of a greenhouse and is absorbed by the plants and hard surfaces inside. Weaker IR (infra-red) radiation, however, has difficulty passing through the glass walls and is trapped inside, thus warming the greenhouse. This effect lets tropical plants thrive inside a greenhouse, even during a cold winter.

A similar phenomenon takes place in a car parked outside on a cold, sunny day. Incoming solar radiation warms the car's interior, but outgoing thermal radiation is trapped inside the car's closed windows.

Greenhouse gases and global warming溫室氣體及全球暖化

"Gas molecules that absorb thermal infrared radiation, and are in significant enough quantity, can force the climate system. These type of gas molecules are called greenhouse gases," Michael Daley, an associate professor of Environmental Science at Lasell College told Live Science. Carbon dioxide (CO₂) and other greenhouse gases act like a blanket, absorbing IR radiation and preventing it from escaping into outer space. The net effect is the gradual heating of Earth's atmosphere and surface, a process known as global warming. 

These greenhouse gases include water vapor, CO₂, methane, nitrous oxide (N₂O) and other gases, according to the Environmental Protection Agency (EPA). Since the dawn of the Industrial Revolution in the early 1800s, the burning of fossil fuels like coal, oil and gasoline have greatly increased the concentration of greenhouse gases in the atmosphere, especially CO₂, National Oceanic and Atmospheric Administration (NOAA). "Deforestation is the second largest anthropogenic source of carbon dioxide to the atmosphere ranging between 6percent and 17 percent," said Daley. 

Atmospheric CO₂ levels have increased by more than 40 percent since the beginning of the Industrial Revolution, from about 280 parts per million (ppm) in the 1800s to 400 ppm today.

The greenhouse effect, combined with increasing levels of greenhouse gases and the resulting global warming, is expected to have profound implications, according to the near-universal consensus of scientists.

If global warming continues unchecked, it will cause significant climate change, a rise in sea levels, increasing ocean acidification, extreme weather events and other severe natural and societal impacts, according to NASA, the EPA and other scientific and governmental bodies.

Benefits of Permeable Pavers:

Groundwater is a source of drinking water for many people. It also nourishes deep-rooted plants and trees. Replenished by rain and melting snow, groundwater has become an endangered resource, partly because of the impermeable materials used in new developments in and around cities and towns. Roofs, roadways and runways, parking lots, driveways, sidewalks, patios, and tennis courts prevent surface water from seeping into the ground.

These impervious surfaces often divert water into storm sewers and then into streams. The rush of water may result in costly and sometimes life-threatening floods. Surface runoff also carries toxic pollutants, such as chemicals and oil from paved roadways and parking lots, into rivers, lakes, and reservoirs, where it pollutes drinking water supplies and harms wildlife.

Another problem caused by so much paving is the buildup of heat in and around cities and towns. Asphalt and concrete absorb sunlight and convert it to heat. The buildup of extra heat around cities and towns is known as the “heat island effect.”

Next time you build a patio, walkway, parking space, or driveway, you can address these problems by installing permeable materials, some of which allow grass to grow in them. Many attractive options will permit water to drain into the ground. Some even reduce heat accumulation around buildings.
