The Bush administration has made no secret of its intent to complete the endangered species changes quickly.
As I indicated above, in order to successfully uplift another species, changes are going to have to be made to the DNA at the embryonic level, if not earlier.
The effects of rising global temperatures are widespread and costly: more severe storms, rising seas, species extinctions, and changes in weather patterns that will alter food production and the spread of disease.
We don't yet know which species will benefit, and which will suffer in response to the changes, but because each species plays a specific ecological role on the tundra, the downfall of one species or proliferation of another could have a domino effect that disrupts the tundra's delicate food web.
Darwin showed in detail how life changes over the course of time by the process of natural selection, but failed to explain how those changes can take different courses, dividing a species in two and thus multiplying the number of species.
The species that have persevered, scientists say, are adaptable to sporadic changes in rainfall.
At the simplest level Future Earth must answer fundamental questions about how and why the global environment is changing, what are likely future changes, what the implications are for the wellbeing of humans and other species, what choices can be made to enhance resilience, create positive futures, and to reduce harmful risks and vulnerabilities, and how this knowledge can support decisions and sustainable development.
Rising water temperatures have led to sudden and dramatic changes - with the plankton breeding at the wrong time, and in the wrong place, threatening species like cod.
The story beginning overleaf assesses the implications for marine biodiversity of transgressing planetary boundaries, due to human-induced changes to the climate system, pollution and ocean acidification, as well as more direct threats like invasive species, overfishing and habitat destruction.
This would mean that we have not only failed to make short-term changes to save biodiversity, but that we have also not made the underlying institutional and behavioral changes that would take us off the long-term course we are on toward the catastrophic loss of species and ecosystems by the end of the century.
