Benefits on global warming

What are the Benefits?

This project potentially brings many benefits, both to the global climate, and also to the local communities where schemes are implemented.

• Immediate impact on climate
• Improved agriculture, forestry and biodiversity
• Increased rainfall and improved water supply
• Reduced flooding, desertification and soil erosion

How much cooling impact can this have?

The project is not concerned with Carbon dioxide and the greenhouse effect, and it does not allow us to stop our efforts to reduce our greenhouse gas emissions. However, it does buy us more time which potentially delaying the effects of global warming by 10-20 years.

Research on global cooling

Global cooling:

What causes global cooling?

 Low level clouds reflect the heat of the sun. Thunderstorm clouds also transport heat from the earth by convection and then radiate it out into space. These clouds can be encouraged to form naturally by increasing soil moisture and vegetation.

How is it done?

Soil moisture can be increased by rainwater harvesting (catching rainwater and helping it percolate into the soil). Other helpful soil moisture interventions include permaculture, conservation agriculture, agroforestry, farmer-managed natural reforestation, soil and water conservation. When done on a large scale, this will increase soil moisture, plant growth, cloud cover and rainfall.

Where can it be done?

This can be effective in hot, semi-arid countries which have a rainy season, especially in parts of the tropics where there has been deforestation. The most promising region is West Africa. Other locations in the northern hemisphere are Florida, India, Ethiopia.

In the picture below, the red, orange, yellow and green areas show where this can be most effective, and at which times of year.

We have found that with so much public fear around the issue of global warming, the phrase "global cooling" is a helpful balancing phrase, which supports people to think about what they and others can actively and realistically do.

For a solution to global warming, most people will think about reducing greenhouse gas emissions. Some will think about large-scale. However, for global cooling, how do we stop this? Thats why we are doing this project.

Options for global cooling go beyond stimulating cloud formation. We also support other strategies which can have an impact before 2050: rapid phase down of HFCs and HCFCs, replacing conifer plantations with broadleaf, and pale roads / cool cities initiatives.

We are also interested in the ongoing research on sea clouds 

Week 2 Reflection

Reflection of the week:
1) What is out title
ANS: Global cooling

2)What do i already know about the topics
ANS: The earth have been affected by cold weather during the Mid December and early January. Even up to now, the earth have been cooling down rapidly

Week 1 Reflection ( 11 nov - 17 nov )

For this fabulous week, I, did all the work for this grace blog....but actually everybody will take turns to post the work and reflection for his week! This week was fun yet tough...why do I say that, it is because the our register no. had a little change as a 'HongKong' guy, named Anton Chan Siu Tong which came in our school during the mids. So, we did the blog and hope that it will be a success. This sums up my reflection!

Group Formation Sheet

This is my first posting in this blog on the 1st assignment posted! What I post for today is the Group formation sheet, telling u what we, the marist united are made up of: Dino(me), Chuan Jian, Gerald and Kai Jie. All of us here have decided on 1 and the finalised topic:

 Climate Change, Global Cooling and Alternative Clean Energy in the 21st Century

Hence we have decided on the post of this blog

Dino Wah  (9) Blogger

Foo ChuanJian  (10) -- Encourager

Gerald lim  (11) -- Questioner
