climate change is a threat to the existence . how can we combat it
Answers
Answer:
Greenhouse gases occur naturally and are essential to the survival of humans and millions of other living things, by keeping some of the sun’s warmth from reflecting back into space and making Earth livable. But after more than a century and a half of industrialization, deforestation, and large scale agriculture, quantities of greenhouse gases in the atmosphere have risen to record levels not seen in three million years. As populations, economies and standards of living grow, so does the cumulative level of greenhouse gas (GHGs) emissions.
The concentration of GHGs in the earth’s atmosphere is directly linked to the average global temperature on Earth;The concentration has been rising steadily, and mean global temperatures along with it, since the time of the Industrial Revolution;The most abundant GHG, accounting for about two-thirds of GHGs, carbon dioxide (CO2), is largely the product of burning fossil fuels.
Climate change adaptation and biodiversity conservation will be mainstreamed into the management of river systems.A mosaic of over 7 million hectares of high conservation value forest, grassland and wetland will be secured, connecting 1,500 km of conservation area.Viable populations of iconic and threatened species will be secured and will live in harmony with human communities.
Climate change has a direct impact on water resources in terms of availability and timing. To tackle the issue WWF is working on interventions that build the resilience of communities and the environment, to water scarcity. One approach has been the development of "Water Smart Communities".
Under WWF's guidance and support water smart communities have been constructing conservation ponds, irrigation ponds, and drinking water reservoirs that collect rainwater in the wet season to be used in the dry season.
Combined with informal education on using scarce water wisely, and sustainable alternatives, farmers have been able to adapt their choice of crop to the changing climate, and generate more income from higher-value alternatives. Pressure is also reduced on the natural water resources and biodiversity that rely on it. The idea of Water Smart Communities has already directly benefited 100's of households across Nepal.
In order to be able to minimise the likely dramatic impacts of climate change, it is important, as a first step, to identify what exactly these impacts might be. Once knowledge at the local level about likely impacts is enhanced, strategies to improve communities and wildlife resilience to climate change can be implemented. These include a range of physical protections and improvements to habitat quality, through a combination of protection, management and restorationactivities
Known as the 'Water Towers of Asia', the Himalayas are the source of many of the world's largest river systems, and have the most glaciers outside the polar region. More than a billion people rely on the vast stores of fresh water in the Eastern Himalayas for domestic and industrial use, agricultural use, power generation, and drinking water. In essence, their survival.
Climate change is predicted to lead to major changes in freshwater flows; impacting on every aspect of freshwater use. Including people's lives, livelihoods and biodiversity.
Explanation:
first climate is very different from weather weather changes by the hour and especially in the UK naturally varies widely between us we know the climate is changing because I have prayed out over longer periods the Global mean temperature has been constantly rising across land and sea it is know about 0.8 Celsius above pre industrial Times
