Shell Oil CEO Predicts Oil Shortage Within Seven YearsLast Updated on 2008-02-04 09:36:52
January 25, 2008 Carl Mortished, UK Times
The oil multinational is predicting that conventional supplies will not keep pace with soaring population growth and the rapid pace of economic development.
Jeroen van der Veer, Shell’s chief executive, said in an e-mail to the company’s staff this week that output of conventional oil and gas was close to peaking. He wrote: “Shell estimates that after 2015 supplies of easy-to-access oil and gas will no longer keep up with demand.”
The boss of the world’s second-largest oil company forecast that, regardless of government policy initiatives and investment in renewables, the world would need more nuclear power and unconventional fossil fuels, such as oil sands.
“Using more energy inevitably means emitting more CO2 at a time when climate change has become a critical global issue,” he wrote.
Mr van der Veer is expected to... More »
Change in Species, Diversity, Ranges and Distribution in the Marine FisheriesLast Updated on 2008-02-01 17:49:06Arctic marine fisheries provide an important food source globally, and a vital part of the economy of the region. Because they are largely controlled by factors such as local weather conditions, ecosystem dynamics, and management decisions, projecting the impacts of climate change on marine fish stocks is problematic. There is some chance that climate change will induce major ecosystem shifts in some areas that would result in radical changes in species composition with unknown consequences. Barring such shifts, moderate warming is likely to improve conditions for some important fish stocks such as cod and herring, as higher temperatures and reduced ice cover could possibly increase productivity of their prey and provide more extensive habitat.
Greenlandic Cod and Climate
A striking example of a positive climate-related impact involves West Greenland cod. Under the very cold... More »
Arctic Vegetation Zones are very Likely to Shift, Causing Wide-Ranging ImpactsLast Updated on 2008-01-31 21:43:37Shifting Vegetation Zones
Climate-induced changes in arctic landscapes are important to local people and animals in terms of food, fuel, culture, and habitat. These changes also have the potential for global impacts because many processes related to arctic landscapes affect global climate and resources. Some changes in arctic landscapes are already underway and future changes are projected to be considerably greater. The major arctic vegetation zones include the polar deserts, tundra, and the northern part of the boreal forest. The northern-most zone that covers most of the high arctic is the polar desert, characterized by open patches of bare ground and an absence of even the smallest woody shrubs. Although polar desert vegetation is quite sparse, musk ox and small sub-species of caribou/reindeer are found in this zone. Tundra is characterized by low shrub vegetation.

Gary Braasch covers environmental issues and conservation, biodiversity and field science, climate change and global warming in stock photography and assignments. Photographs of landscape, patterns, forests, Antarctica, the Arctic, cities and travel destinations are used by publications worldwide. His photography grows from a deeply felt connection with nature and an ardent conservation ethic.
In the last decade major articles and portfolios of his photography appeared in Time, LIFE, Discover, Audubon, National Wildlife, Smithsonian, Scientific American, International Wildlife, Natural History, Sierra, Animals, French Terre Sauvage, French Photo, Outdoor Photographer, Photo District News, 2wice, BBC Wildlife and the Swiss Animan magazine.
Most of this work is on conservation or natural history subjects, the coverage of which gained Gary... More »
