Global Climate Change and Snow melting



Snow is an important component of the cryosphere and an integral part of the global climate system; snow cover both affects and is affected by patterns of climate and climate change. Observation and monitoring of components of the cryosphere are necessary for an understanding of the cryospheric and terrestrial climate system. Predictions about the future state of the environment, in particular the functioning of the climate system cannot be attempted without through analysis of cryospheric processes.

The earth’s surface where water is founded in solid forms such as ice, glaciers, and permafrost. In the northern hemisphere in winter with, about 50% of the land surface is covered with snow. Snow is the important that changes most rapidly with the seasons. Because of the feedback effects these changes generate and their influence on surface energy and atmospheric process. Snow is an important focus for research into climate change and adaptation. Monitoring snow-covered areas and making timely information available on snow cover thus contribute to providing a scientific basis for sound government policies on water use and adoption to climate change. Recently changes have been observed in snowfall patterns with respect to timing, intensity and duration. The anticipated changes in precipitins patterns driven by climate change is likely to have a considerations impact on the Himalayan cryospheric for freshwater.
Snow plays a vital role in the energy and water budgets of drainage basins in the Himalayan regions. Snow and glacier melt constitute 50 to 90% the total river discharge in some major rivers systems during the dry season. Hydrological modeling in Himalayan region is very difficult owing to the limited data available from the sparse observation networks and the enormous spatial variability of runoff formation factors such as snow process.

Snow Glaciers Data:
Developing and validating a new algorithm and having it endorsed by the scientific communities are a protracted and rigorous process. Climate science needs long-terms data to predict future trends. Several researchers have expressed the need for snow data over a longer term than currently available as a basis for credible research on climate change. The global snow cover products still have scope for further improvement in terms of accuracy, but they provide a good first assessment of snow cover status and an indication of where efforts should be focus.  Snow cover is one factor among a range of environmental data needed to understand the complex system of climate and other change. Access to data is another important aspect which needs addressing. In this case it will be important to develop appropriate ways to share the snow data. Hydrological runoff models for estimation of water resources should be promoted and the use of snow-cover data should be encouraged. It is important to ensure that the data should be easily accessible which can be used to support research on climate change and climate change adaptation, as well as more immediate local purpose.

Glaciers:
Accelerated melting of glaciers due to global warming is worldwide phenomenon. Glacier retreat increases the risk climate hazards, such as glacier lake overflows, known as Global Glacial Lake Partnership (GLOF) the management of which is one of the new challenges posed by climate changes in high mountains environments.


In conclusions, all the challenges what we have been facing can be solve through raising collective voice. Ongoing international negotiations on climate change and sustainable development offer us all a major opportunity to have a collective bargaining and platform that can ensure that we are not only heard, but our issues should be taken on international climate conferences. Therefore, there is an urgent need to make progress in climate change negotiations and to ensure enhanced and predictable financing, especially for the developing and vulnerable countries. This calls for urgent action by all to reduce greenhouse emissions based on the principle of equity to address the root causes and support the developing countries to adapt climate change and impact mitigation. This needs new and additional financial resources, expedited provisions for climate and environment-friendly technologies and support capacity building. Climate change data management system should be emphasized.

ClimateChange and COP 18 Decisions



The negotiators in Doha Climate Conference failed to deliver on the expectations of the most vulnerable communities across the globe. Representatives from almost 200 countries deliberated on how to curb carbon emission, providing finance for developing countries and set a mechanism to compensate developing countries to deal with 'loss and damage' due to climate change. But the two weeks long conference ended without any concrete decisions on any of the issues above and came up with a weak agreement to continue dialogue in the days to come.



COP 18 Doha Climate Change Conference
The conference also know n as the 'Conference  of the parties-COP' held from November 26 to December 8, 2012 of its kind after the global leaders ratified United Nations Framework Convention on Climate change (UNFCCC) in Earth Summit held in 1992. Twenty years after the
countries agreed to set out a framework for action aimed at stabilizing atmospheric concentrations of greenhouse gases (GHGs) to avoid "dangerous anthropogenic interference" with the climate system, the world leaders are yet to find the common agreement to realize that objectives.
with the science more clear on the impacts of human induced climate change and warnings that the planet is set be warmer by 4 to 6 degrees Celsius (reports from World Bank and others) by the end of the century, the negotiators in Doha were thought to be engaged in plucking out decisions that would be in the best interest of the people and the planet. However, the conference ended with low ambitions in terms of emission cuts by developed countries and funding required for the developing countries. the recent scientific reports suggest that the carbon emission must be cut to the scale of  25 to 40 per cent by 2020 and 50 per cent by 2050 below 1990 level to limit the global average temperature below 2 degree Celsius. moreover, of limiting temperature rise below 2 degree Celsius.
one important decisions reached in Doha was the adoption of second commitment period of Kyoto protocol (2013 to 2020) which follows immediately after the first commitment period ends in 2012. the Kyoto protocol is the only legally binding international agreement in which developed countries agree to cut the emissions. however, the elements of the protocol are weak as The United States is not a party to the protocol and the countries like Japan, Russia, Canada and New Zealand having pulled out of the second commitment period. Likewise, in developing countries deal with the loss and damage caused by climate change. The conference did little to mobilize finance required for developing countries. The Cancun conference 2010 had agreed to mobilize climate finance of US $ 100 billion per year by 2020 and fast start finance of US $ 30 billion would be provided in the period 2011-2012. the fast start commitment was met only in papers (with no clarity on the difference between the climate finance and conventional development aid) the Doha Conference could not decide on how the required financing for the period of 2012-2020 will be mobilized.

The Doha conference was an important milestone for Nepal. Nepal was handed over the responsibility of coordinating the group of Least Developed Countries in the UNFCCC negotiations for the year 2013-2014. Now, Nepal has ample opportunities and the challenges of advancing the agenda of LDCs apart from voicing its own agenda. Ldcs comprise of 48 countries which are very poor in economic terms. however, these countries are divergent in their interest and needs. So, Nepal needs to show a strong leadership to coordinate the LDCs and advancing LDCs as a strong negotiating block within the UNFCCC. Moreover, as in the last couple of years Nepal is championing mountain agenda which needs to be continued and may not be the interest of most of the LDCs. at a time, the developed countries are reluctant to play constructive and positive role to tackle climate change, how Nepal fares to be the leader of the LDCs will be interesting to see.
The positive aspect is the decision to continues the Kyoto protocol and the agreement of the EU, Australia, Norway, Switzerland, Liechtenstein, Monaco, Croatia, and Iceland to engage in a second commitment period (Kyoto 2). This means that the only binding international agreement on the reduction of climate damaging greenhouse gas emissions that existed up to now will be extended to 2020. It is expected to transmit presumptuous the effort on adaptation, mitigation, finance, technology transfer and development, capacity-building and finance, including their gender dimensions.
as the developed countries seem to be undermining the UNFCCC process, there is no alternative for the governments of the developing countries / Least Developed countries to continue dialogue inside the UNFCCC process. The slow progress in the process, however calls for the increased voices and more public participation across the globe to push for the fear ambitious and legally binding climate treaty.

The 18th sessional of the conference of parties serving as the meeting of the parties to the Kyoto Protocol concluded on 8, December 2012 at the Qatar National Conventional Center in Doha Qatar. the conference was hosted by the government of Qatar and supported by the UNFCCC Secretariat



Overall Summary of COP 18

Final Decision 

(1) COP 18 opened in November 26 and ended in December 8,. It held in Doha, Qatar. Representative from almost 200 countries  participated in the conferences.

(2) Concluded working-level negotiations at the Ad-Hoc Working Group on the Durban Platform for Enhanced Action (ADP), the Ad-Hoc Working Group on Further Commitments for Annex I Parties under the Kyoto Protocol (AWG-KP), and the Ad-Hoc Working Group on Long-term Cooperative Action under Convention (AWG-LCA) as well as meetings at two subsidiary bodies, and further ministerial-level discussions at the High-Level Segment from December 5 through 7, the following COP and CMP decisions were adopted as the “Doha Climate Gateway”. The COP and CMP decisions on other issues were also adopted.
1.      (A) COP decisions including the ADP work plan
2.      (B) CMP decision concerning Amendments to the Kyoto Protocol
3.      (C) COP decision concerning the agreed outcome of the AWG-LCA
4.      (D) A series of COP decisions concerning climate finance
5.      (E) COP decision concerning loss and damage associated with climate change impacts
(3) Accordingly, the AWG-KP and the AWG-LCA concluded their works and terminated their activities while the arrangements for negotiations in the ADP from next year onwards were agreed (Cf. “3. Outcomes of the conferences” below). As a result, the Government of Japan has achieved its goal of sending a message that “basic arrangements for negotiations have been set up toward an agreement by 2015 on a new legal framework beyond 2020”.
