The Issue: Repeated warnings of climate change impacts have obtruded scientists, civil society and indigenous peoples to look for initiatives and solutions. A thousand pace should be taken before a negative impact in the world, more notably global warming due. Before a solution has been met, we have already suffered the impacts. For instance, floods, droughts, epidemics, diseases, and uncertain climate conditions are negative impacts due to climate change. So, it is very important to...

Solar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, solar photovoltaics, solar thermal electricity, solar architecture and artificial photosynthesis. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to har...

GLOBAL WARMING The American Geophysical Union (AGU) stated that human activities, especially the burning of fossil fuels, such as coal and petroleum, have significantly increased atmospheric concentrations of greenhouse gases (gases such as carbon dioxide that trap solar radiation). The continued build-up of these gases in the atmosphere is expected to cause major disruptions to the global climate system, including rising average surface temperatures, rising sea levels caused b...

Tragedy after tragedy, same topic every decade with no absolute idea to do away with the scourge. Climate change with a negative effect in the lives of the old, the young and more especially the youth who are considered to be the leaders of tomorrow. One among many areas of concern is the socio-economic sector. The natural causes of climate change is addressed by a layer which protects us from the harmful rays of the sun; this protective layer is called the ozone layer. But the activities undert...

The combustion of wood, oil and coal results in increased levels of carbon monoxide and carbon dioxide in the atmosphere. Carbon dioxide acts as a greenhouse gas because it lets natural light in through but traps out on going long-level radiation. The consequence is that increased levels of carbon dioxide are slowly making the earth warmer causing climate change. Greenhouse gases can cause depletion of the ozone layer which protects humans from cancer of the skin. It also reduces...
