STEP 2: PROBLEMS OF GLOBAL WARMING
PROBLEMS OF GLOBAL WARMING
Identify Problems: What main situation or issues or problem behind the topic?
1. 1. Energy recovery from wastes has a great potential for
reducing CO2 emissions and thereby resulting in greenhouse gas (GHG) emissions
2. 2.Global warming as a waste disposal problem.Carbon dioxide
remains in the atmosphere causing pollution to be removed from tailpipes and
power plants, trapping heat and heating the planet
3. 3.In reality about 30% of waste generated never gets to
disposal sites (Agunwamba, 1998)
4. 4.This paper is part of an extensive study of secondary school
students’ preconceived ideas about climate change.
5. 5.Recycling of waste materials has been analysed from a life
cycle perspective in a number of studiesover the past 10–15 years.
6. 6.A worldwide temperature alteration has possibly disastrous
effects in Amazonia, while simultaneously support of the Amazon backwoods
offers perhaps the most important and financially savvy option for alleviating
environmental change
7. 7.Global warming caused by tropical deforestation. The planet’s largest areas of tropical forest are the Amazon basin in South America, the Congo Basin in Central Africa, and Southeast Asia. The amount of deforestation, and its causes, are quite different in these three regions.
8. 8.The presence of excess nitrogen in the atmosphere.
9. 9.Burning fossil fuels has caused dramatic change to Earth’s
climate.
Problem
Analysis:
Analyze the situation or issues
from different perspective to identify main problem
1. 1.Evaluate and compare environmental impacts of various food
waste management systems: Anaerobic digestion, co-digestion with sewage sludge,
and volume reduction using a garbage dryer followed by incineration from
generation to final disposal.
2. 2.Emissions in terms of trash that needs to be taken out may
draw more attention to something called negative carbon emissions the process of physically removing carbon
dioxide from the air to reduce its concentration in the atmosphere
3. 3.Carry out an assessment study of waste composition and
generation rates in Nigeria . Waste collection has been the priority.
4. 4.This research aims, as far as possible, to ascertain
secondary school students’ (aged between 12 and 16) prior knowledge of the
causes and consequences of climate change.
5. 5.Nevertheless, the general
public as well
as decision makers
often question whether recycling
is really the
best option, and
researchers struggle to
given answer.
6. 6.The goal of the United Nations Framework Convention on
Climate Change (UN-FCCC), also known as the "climate convention," is
to avoid greenhouse gas concentrations in the atmosphere from reaching levels
that create "dangerous interference with the global climate system"
(UN-FCCC, 1992, Article 2). The definition of "dangerous
interference" is still being negotiated.
7. 7.Identify how tropical deforestation contributes to global
warming
1. 8. Ways to reduce nutrient pollution.
2. 9. Cleaner technologies such as renewable energy coupled with energy storage and improved energy efficiency can support a more sustainable energy system with zero carbon emissions.
10.There is keen interest in climate change issues due to a fast-increasing rate of GHG emissions. This has emphasized the need to innovate and establish right approaches to better design, control and optimize WWTPs on the plant -wide scale.Relevance Information and references

Initiative, effort for Self- Learning
1. 1.Our
group has used the internet as the medium to self- learn and know a lot about
the information related climate change caused by global warming.
2. 2.We
referred articles, websites and thesis
by experts all over the world to search for information.
3. 3.We
discussed among friends and exchanged thoughts and opinions on this climate
change caused by global warming topic.
