What can countries do to stop climate change?
Climate change mitigation (GHG reduction)
- increased use of renewable energy (wind, solar, biomass) and combined heat and power installations;
- improved energy efficiency in buildings, industry, household appliances;
- reduction of CO2 emissions from new passenger cars;
- abatement measures in the manufacturing industry;
Why is it difficult for countries to work with climate change?
Furthermore, developing countries often have limited social safety nets, widespread poverty, fragile health care systems, and weak governmental institutions, making it harder for them to adapt or respond to climate change and not to forget that many developing countries have the highest birth rates.
Which countries are most at risk of climate change?
The Arctic, Africa, small islands and Asian megadeltas and Australia are regions that are likely to be especially affected by future climate change. Africa is one of the most vulnerable continents to climate variability and change because of multiple existing stresses and low adaptive capacity.
Which country causes the most pollution?
Top 10 polluters
- China, with more than 10,065 million tons of CO2 released.
- United States, with 5,416 million tons of CO2.
- India, with 2,654 million tons of CO2.
- Russia, with 1,711 million tons of CO2.
- Japan, 1,162 million tons of CO2.
- Germany, 759 million tons of CO2.
- Iran, 720 million tons of CO2.
How are countries reducing greenhouse gases?
Reducing emissions means substituting our most carbon-intensive energy sources, such as coal and natural gas, with cleaner sources, such as hydropower, geothermal, biomass, solar and wind power. Most developed countries have agreed to significantly reduce their emissions, and many have already made noteworthy progress.
Why is it so difficult to stop climate change?
1: Responding to flooding, heat waves and other extreme weather that climate change is often making worse. Cost No. 2: Enacting policies to reduce emissions, which would come in the form of higher fossil-fuel costs today.
Why is it difficult to solve environmental problems?
Environmental problems can be complex and hard to resolve. The complexity arises because the components of the environment are linked, and their interactions may be separated by both time and distance.
What countries cause the most pollution?
What is the most harmful to climate change?
More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities. As climate change worsens, dangerous weather events are becoming more frequent or severe.
What causes the most pollution?
Most of the air pollution takes place due to the burning of fossil fuels such as coal, oil, gasoline to produce energy for electricity or transportation. The release of carbon monoxide in high level indicates how much fossil fuel is burned. This also emits other toxic pollutants in the air.
Why do some countries find it difficult to reduce their carbon emissions?
Firstly, lower than expected demand for a commodity results in lower prices making a further reduction in demand more difficult. Secondly, the benefits of CO2 emission reductions are global and long term; the associated costs are local and are incurred now. This implies that there is always a strong incentive to cheat.
