Role of Tourism Sector in Climate Change – A Perspective
Undeniable evidences throughout the globe indicate that tourchaipa global climate has changed compared to the pre-industrial era and is expected to continue the trend through 21st century and beyond. The Inter-governmental Panel on Climate Change (IPCC)1 documented that global mean temperature has increased approximately 0.76°C between 1850-1899 and 2001-2005 and it has concluded that most of the observed changes in global average temperatures since the mid-20th century is ‘very likely’ the result of human activities that are increasing greenhouse gas concentrations in the atmosphere.
As a consequence, we observe various manifestations of climate change including ocean warming, continental-average temperatures, temperature extremes and wind patterns. Widespread decreases in glaciers and ice caps and warming ocean surface temperature have contributed to sea level rise of 1.8 mm per year from 1961 to 2003, and approximately 3.1 mm per year from 1993 to 2003.
The IPCC has projected that the pace of climate change is to accelerate with continued greenhouse gas (GHG) emissions at or above the current rates. IPCC best estimate suggested that globally averaged surface temperatures will rise by 1.8°C to 4.0°C by the end of the 21st century. Even with a stabilized atmospheric concentration of GHGs at the current level, the earth would continue to warm as a result of past GHG emissions as well as the thermal inertia of the oceans.
Future changes in temperatures and other important features of climate will manifest themselves in different fashions across various regions of the globe. It is likely that the tropical cyclones (typhoons and hurricanes) will become more severe, with greater wind speeds and heavier precipitation. This will be associated with continuing increase of tropical sea surface temperatures. Extra-tropical storm tracks are projected to shift towards the pole, with consequent changes in wind, precipitation and temperature patterns. The decreases in snow cover are also projected to continue.
The environmental and economic risks associated with predictions for climate change are considerable. The gravity of the situation has resulted in various recent international policy debates. The IPCC has come out with firm conclusions that climate change would hinder the ability of several nations to achieve sustainable development. The Stern Review on the Economics of Climate Change found that the present cost reducing GHG emissions is much smaller than the future costs of economic and social disruption due to unmitigated climate change. Every country as well as economic sectors will have to strive with the challenges of climate change through adaptation and mitigation.
Tourism is no exception and in the decades ahead, climate change will play a pivotal role in tourism development and management. With its close links to the environment, tourism is considered to be a highly climate-sensitive sector. The regional manifestations of climate change will be highly relevant for tourism sector that demands adaptation by all major tourism stakeholders. In fact, it is not a remote future for the tourism sector since varied impacts of a changing climate are already evident at destinations around the world.
