IPCC report — climate change impacts are a fact of life
Adapting to a new environment
The trans-boundary nature of climate change means that successful adaptation strategies will take time and will require coordination at local, national, regional, and international levels.
Professor Jacqueline McGlade
The IPCC report, 'Climate Change Impacts, Adaptation and Vulnerability', is the second of three major reports planned by the UN panel of international scientists. The report says climate change is already affecting the global environment and that drought, flooding and changes to seasonal patterns will increase as global temperatures increase. However, the extent of the impacts will be closely linked to the increase in temperature.
The report underlines the fact that many of the most vulnerable regions are in developing countries in Africa, Asia as well as island communities around the globe. However, the entire global community will be affected. As a result, effective adaptation measures must be coordinated, according to Professor McGlade.
'The trans-boundary nature of climate change means that successful adaptation strategies will take time and will require coordination at local, national, regional, and international levels,' she said.Professor McGlade stressed, however, that the focus must still remain on controlling and reducing increases to the global climate as a first priority.
'We can delay and reduce some of the effects of climate change by cutting emissions of greenhouse gases — the drivers of global temperature increases. However, real cuts must start now as there will be a lag time before reductions have a positive effect. Failure to do so could lead to major adverse, possibly irreversible impacts that are beyond the capacity of many regions to adapt to,' she said.
The IPCC report presents observed and projected changes that include:
- Increasing global ice melt leading to enlargement and increased numbers of glacial lakes, with increased risk of outburst floods
- Increasing ground instability due to thawing in high-Alpine mountain and other permafrost regions
- Growing risk of ice and rock avalanches in mountain regions
- Enhanced run-off and earlier spring peak discharge in many glacier and snow-fed rivers
- Lake and river warming — affecting thermal structure and water quality
- Earlier spring events: leaf unfolding, bird migration and egg-laying, for example:
- Shifting ranges of plant and animal species
- Changing Arctic and Antarctic flora and fauna with far-reaching disruptions of the food chain.
The IPCC report also shows that some adaptation is already occurring. However, more extensive adaptation is required in vulnerable regions and sectors (such as water resource management; human health; agriculture; building sector).
