CLIMATE CHANGE AND ITS CHALLENGES

Climate change is one of the most critical global challenges of our time. Recent events have emphatically demonstrated our growing vulnerability to climate change. Climate change impacts will range from affecting agriculture- further endangering food security-, sea-level rise and the accelerated erosion of coastal zones, increasing intensity of natural disasters, species extinction and the spread of vector-borne diseases.

Climate change refers to the variation in the Earth’s global climate or in regional climates over time. It describes changes in the variability or average state of the atmosphere over time scales, ranging from decades to millions of years. These changes can be caused by processes internal to the Earth, external forces (e.g. variations in sunlight intensity) and, more recently, human activities.

In recent usage, especially in the context of environmental policy, the term “climate change” often refers to changes in modern climate which according to the IPCC are 90-95% likely to have been in part caused by human action. Consequently the term anthropogenic climate change is frequently adopted; this phenomenon is also referred to in the mainstream media as global warming. In some cases, the term is also used with a presumption of human causation, as in the United Nations Framework Convention on Climate Change (UNFCCC). The UNFCCC uses “climate variability” for non-human caused variations.

Weather is the day-to-day state of the atmosphere, and is a chaotic non-linear dynamical system. On the other hand, climate — the average state of weather — is fairly stable and predictable. Climate includes the average temperature, amount of precipitation, days of sunlight, and other variables that might be measured at any given site. However, there are also changes within the Earth’s environment that can affect the climate.

Glaciation

Glaciers are recognized as one of the most sensitive indicators of climate change, advancing substantially during climate cooling (e.g., the Little Ice Age) and retreating during climate warming on moderate time scales. Glaciers grow and collapse, both contributing to natural variability and greatly amplifying externally-forced changes. For the last century, however, glaciers have been unable to regenerate enough ice during the winters to make up for the ice lost during the summer months.

Many climate fluctuations, the best known being the El Niño Southern oscillation but also including the Pacific decadal oscillation, the North Atlantic oscillation, and Arctic oscillation, owe their existence at least in part to different ways that heat can be stored in the oceans and move between different reservoirs. On longer time scales ocean processes such as thermohaline circulation play a key role in redistributing heat, and can dramatically affect climate.

Climate Change Outreach Programme

Responding to the needs of the countries and following the request from the UNFCCC Secretariat, UNEP/DEC has initiated and implemented a major programme on climate change outreach that directly supported the UNFCCC New Delhi Work Programme on Article 6 (Education, Training and Public Awareness) The objectives of this project are to provide to Governments additional tools for promoting climate change awareness at the national level. Support efforts by associations and NGOs to provide accurate and accessible messages of IPCC on climate change to their memberships or target audiences, make the youth more aware of the climate change implications and motivated to take relevant climate friendly actions, and raise awareness of general public on climate change problems with easily understandable graphic materials. Project partners include the Governments of Kenya, Ghana , Namibia , Russia , Uzbekistan , Mexico , Albania , Georgia, the UNFCCC and IPCC Secretariats, WWF, TERI, the Government of Norway and other donors.

National Climate Outreach Campaigns

Those campaigns have been implemented in Namibia , Ghana , Kenya , Russia , Uzbekistan , Albania and Georgia . Each campaign identified local needs and priorities for implementing national-level Article 6 activities, promoted collaboration and networking among focal points and key stakeholders, produced popular brochures and booklets in local languages, organized radio and TV presentations on hot climate topics – and much more. In Latin America UNEP/DEC supported publication of a Handbook on Climate Change Communications for local practitioners that was successfully tested at a regional workshop with participants from 10 countries of the region.

Climate Outreach to Youth

UNEP has entered into a partnership with TERI Institute ( India ) to promote environmental education among the school children in India . This programme covered more than 100 schools in 8 states of the country and featured establishing school climate clubs, workshops and seminars for children, arranging climate-related shows and presentations and compiling guide books on climate change for teachers.
