Some causes of global warming:

Ocean

evap

orat

ion

Mammal methane!

Deforestation

Aerosols

Exhaust fumes

Volcanoes

Industry/factory emissions

Some effects of global warming:

Ice caps are melting

African crops are poor due to climate change, causing starvation.

Droughts

Rising water levels

Hole in the ozone layer

Animals losing their habitats and/or becoming extinct

Extreme climates

The global average surface temperature fluctuates over time, but recently it has increased dramatically. From 1920 to the present, the earth’s average surface temperature has increased by 1.4 °F. According to the National Academy of Sciences, this change is the largest global temperature rise in at least the last 2,000 years and, possibly, the last 5,000 years. The sharpest rise occurred between 1975 and 2005, when temperature rose steadily by about 1 °F.   To see the relationship between surface temperature and the concentration of CO2 in the atmosphere.

Climate change from 1845 - 2005

Globally, the primary sources of greenhouse gas emissions are the energy supply sector, industry and forestry. Agriculture and transportation account for 14% and 13% of total emissions, respectively.

GreenHouse Gas

Caused or produced by humans.

Where are all these green house gases coming from?

Most of the world's greenhouse gas (GHG) emissions come from a relatively small number of countries. The United States, China, and the European Union (EU-25) together accounted for about 50% of global emissions in 2004.

It’s not all doom and gloom…In order to meet the raw material demands of a modern pulp mill,

the Sarawak State Government entrusted the Forest Department Sarawak with establishing 150,000 hectares of industrial tree plantations. To date, 100,000 hectares have already been established and an additional 2,000 hectares are being planted every month – Sustainable sources! Planted Forests Project

Risks assessments are now being carried out in protected areas and in places where protected/endangered species live.Assessing risk to a protected area | Case studies | Environmental management | BP

BP’s solar business has been in operation for over 30 years and last year had sales of 162 megawatts (MW) globally. This represents an increase of 29 percent over 2007 and while economic conditions have slowed growth recently, BP Solar is well-positioned to grow sales as global economic conditions improve.

There are many more positive steps towards improving the rate of global warming and GHG emissions, what can you find?
