520 2    |a The climate of our planet is changing. The climate has always been variable, but today there is a growing concern over climate change issues, perhaps because the magnitude of the change seems to be unprecedented but, more importantly, because there is strong evidence to suggest that humanity might be directly responsible for climate change. Any change in climate would lead to destabilization of environmental and social conditions all around the globe. These disturbances could jeopardize the conservation of natural ecosystems and sustainability of socioeconomic systems. Consequently, climate change will also adversely affect, and indeed is already affecting, the conservation of World Heritage properties, both natural and cultural. Heritage is an irreplaceable source of life and inspiration, it is humankind’s legacy from the past, with which we live in the present and pass on to future generations. Our planet is kept warm due to the socalled greenhouse effect. This effect consists of trapping the energy – radiated by the earth into the atmosphere – instead of allowing it to escape into outer space. The greenhouse gases involved in this regulatory mechanism are usually found in the atmosphere at very low concentrations. Carbon dioxide (CO2) molecules are never found at concentrations higher than a few hundred parts per million (ppm) of air parcels. Nevertheless they play a critical role in the climatic equilibrium of the planet. Prior to the Industrial Revolution, CO2 concentration was 280 ± 10 ppm for several thousand years. But the present atmospheric CO2 concentration is above 360 ppm and such a level has never been reached over the past 420,000 years.1,2 Changing CO2 concentrations in the atmosphere will undoubtedly have an impact on the climate system, but the processes involved are multiple, complex, and feedback on one another. Extensive research is being carried out worldwide to understand better our impact on the changing climate of planet Earth. The Intergovernmental Panel on Climate Change (IPCC) was established under the auspices of the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) to assess, compile and synthesize scientific, technical and socio-economic information relevant to our comprehension of climate change, its potential impacts, and outline options for adaptation and mitigation. The periodic Assessment Reports of the IPCC constitute the best synthesis of the state of our knowledge of climate change. According to the IPCC, global average temperature increase has reached 0.6 ± 0.2 °C over the twentieth century.3 There has been a widespread retreat of mountain glaciers in non- Polar Regions. Northern Hemisphere spring and summer sea-ice extent has decreased by about 10% to 15% since the 1950s. The global ocean heat content has increased since the late 1950s and the global average sea level rose by at least 0.1 m during the twentieth century. The IPCC also develops possible scenarios for anthropogenic emissions in order to project future climate trends. Depending on these scenarios, climate models project that by 2100 atmospheric CO2 concentrations will reach 540 to 970 ppm. The global average surface temperature is projected to increase by 1.4 °C to 5.8 °C over the period 1990 to 2100.4 Global mean sea level is projected to rise by 0.09 m to 0.88 m between 1990 and 2100.5 Global average water vapour concentration and precipitation are projected to increase during the twenty-first century, and larger year-to-year variations in precipitation are very likely over most areas where an increase in mean precipitation is projected. Changes in extreme and/or severe weather events such as heat waves, droughts, extreme precipitations, severe tropical cyclones, can also be expected.
