Terminology Terminology on Disaster Risk Reduction Basic definitions on disaster risk reduction to promote a common understanding on the subject for use by the public, authorities and practitioners. More information about the Open-ended intergovernmental expert working group on indicators and terminology relating to disaster risk reduction. Below is the complete list of the disaster risk terminology recommended by the Open-ended intergovernmental expert working group and adopted by the United Nations General Assembly. Directly affected are those who have suffered injury, illness or other health effects; who were evacuated, displaced, relocated or have suffered direct damage to their livelihoods, economic, physical, social, cultural and environmental assets.
Shop What is the Greenhouse Effect? Before we dig deep into the causes of greenhouse effect, it is important for us to know what is greenhouse effect. You must have heard of greenhouse effect during any debate on global warming.
The light that we get from the sun helps to keep this planet warm. It can be used to produce solar energy, drying clothes, or by plants in the process of photosynthesis. The absorption of these radiations by greenhouse gases makes it possible to keep this planet warm for humans.
Without Greenhouse effect, the temperature of this planet would be lesser by 30 degree Celsius and this would be too cold for us to survive. Greenhouse effect is not bad.
In fact, it is needed for all of us to survive on planet Earth. This in turn raises the average temperature of the Earth.
Causes of the Greenhouse Effect 1. Burning of Fossil Fuels: Fossil fuels like coal, oil and natural gas have become an integral part of our life. They are used on large basis to produce electricity and for transportation. With the increase in the population, the number of vehicles have also increased and this has resulted in increase in the pollution in the atmosphere.
When these vehicles run, they release carbon dioxide, which is one the main gas responsible for increase in greenhouse effect. Apart from that, electricity-related emissions are high because we are still dependent on coal for electricity generation which releases large amount of CO2 into the atmosphere and is still the primary source of fuel for generating electricity.
Although, renewable sources are catching up, but it may take a while before we can reduce our dependance on coal for electricity generation. Forests hold a major green area on the planet Earth.
Plants and trees intake carbon dioxide and release oxygen, through the process of photosynthesis, which is required by humans and animals to survive. Large scale development has resulted in cutting down of trees and forests which has forced people to look for alternate places for living.
When the wood is burnt, the stored carbon in converted back into carbon dioxide. Over the last few decades, there have been huge increase in the population.
Now, this has resulted in increased demand for food, cloth and shelter. New manufacturing hubs have come up cities and towns that release some harmful gases into the atmosphere which increases the greenhouse effect.
Also, more people means more usage of fossil fuels which in turn has aggravated the problem. Nitrous oxide is one the greenhouse gas that is used in fertilizer and contributes to greenhouse effect which in turn leads to global warming.Native Species Species that normally exists and reproduces in a specific region of the Earth.
Compare with immigrant species, indicator species, and keystone species. Natural Gas. 7. Dimension 3 DISCIPLINARY CORE IDEAS—EARTH AND SPACE SCIENCES. E arth and space sciences (ESS) investigate processes that operate on Earth and also address its place in the solar system and the galaxy.
Thus ESS involve phenomena that range in scale from the unimaginably large to the invisibly small. The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.
If a A runaway greenhouse effect occurs if positive feedbacks lead to the evaporation of all greenhouse gases into the atmosphere.
The Greenhouse Effect and Its Impacts on Environment. The Greenhouse Effect Definition Radiation: energy that is propagated in the form of electromagnetic waves. Incoming solar energy is. What are the ways greenhouse gases hurt the environment?
By: social Posted on: September 30, Despite evidence that greenhouse gases have a detrimental effect on the environment, many people are unconcerned about the effects of climate change.
When climate change due to greenhouse gases occurs, it affects power plants in a. Consequences of greenhouse-effect temperature rises Predicting the consequences of global warming is one of the most difficult tasks for the world’s climate researchers.
This is because the natural processes that cause rain, hail and snow storms, increases in sea level and other expected effects of global warming are dependent on many.
