Answers
Answer:
Global warming or climate change has today become a major threat to the mankind. The Earth’s temperature is on the rise and there are various reasons for it such as greenhouse gases emanating from carbon dioxide ($CO_2$) emissions, burning of fossil fuels or deforestation.
Impact of Greenhouse Gases
The rise in the levels of carbon dioxide ($CO_2$) leads to substantial increase in temperature. It is because $CO_2$ remains concentrated in the atmosphere for even hundreds of years. Due to activities like fossil fuel combustion for electricity generation, transportation, and heating, human beings have contributed to increase in the $CO_2$ concentration in the atmosphere.
Global Warming: A Gradual Phenomenon
Recent years have been unusually warm, causing worldwide concern. But the fact is that the increase in carbon dioxide actually began in 1800, due to the deforestation of a large chunk of North-eastern American, besides forested parts of the world. The things became worse with emissions in the wake of the industrial revolution, leading to increase in carbon dioxide level by 1900.
Cause of Concern
According to the Intergovernmental Panel on Climate Change (IPCC), global temperature is likely to rise by about 1-3.5 Celsius by the year 2100. It has also suggested that the climate might warm by as much as 10 degrees Fahrenheit over the next 100 years.
Impact of Global Warming
The sea levels are constantly rising as fresh water marshlands, low-lying cities, and islands have been inundated with seawater.
There have been changes in rainfall patterns, leading to droughts and fires in some areas, and flooding in other areas.
Ice caps are constantly melting posing a threat to polar bears as their feeding season stands reduced.
Glaciers are gradually melting.
Animal populations are gradually vanishing as there has been a widespread loss of their habitat.
Conclusion
As per Kyoto protocol, developed countries are required to cut back their emissions. There is a need to reduce coal-fired electricity, increase energy efficiency through wind and solar power, and also high efficiency natural gas generation

Answer:Lao People's Democratic Republic (hereafter "Lao PDR") was the first country in Asia to submit its NDC, doing so in September 2015. Building on national development and environmental protection policies, the country aimed to make full use of existing institutional capacity and financial resources, and embed NDC targets in existing policies and planning.
To date, NDC results have been mixed. The initial target for 90% of the rural population having access to electricity has already been exceeded with the figure now at 95%, while the forestry target of 70% forest cover has yet to be achieved.
Political commitment is strong. The Government designated the Department of Climate Change (DCC) under the Ministry of Natural Resources and Environment (MoNRE) to become the national focal point for coordinating NDC implementation in Lao PDR. The Government has also issued a number of related laws and regulations, such as the new forestry law in June 2019 and the Decree on Climate Change in September 2019.
Major challenges impeding the country's efforts to achieve its forestry sector NDC targets are persistent and similar to those identified 10 years ago. These are: policies and measures to address major drivers of deforestation and forest degradation not being fully implemented on the ground; poor coordination between key sectors; a lack of accurate and available data and credible methodologies for measuring outcomes; inadequate institutional arrangements for sustainable forest management and community participation; as well as a lack of available funds for implementing proposed activities.
In order to achieve and enhance current NDC target ambitions, policies, measures and enabling conditions for transformational change (e.g. funding availability, national ownership, cross-sector collaboration, results-based payment mechanisms, and clarity over carbon and non-carbon benefits) need to be in place.
Knowledge gaps that need addressing in order to provide credible evidence for the Government and donors to revise and adapt NDC targets, and better implement the NDC include: rigorous impact assessments of existing policies and initiatives on forest protection and development outcomes; and an integrated sectoral assessment on how realistic and feasible NDC targets could be achieved in supporting the National Green Growth Strategy and Sustainable Development Goals by mainstreaming Climate Change into national socio-economic development plans, vis-à-vis Paris Agreement ambition targets in each period.
