Massive ecological change predicted for Canada: NASA

Many parts of Canada are predicted to see massive ecological changes over the next century, according to NASA.

Researchers from the space agency's Jet Propulsion Laboratory and the California Institute of Technology investigated how Earth's plant life is likely to react over the next three centuries to changes in climate brought about by rising levels of human-produced greenhouse gases.

"While warnings of melting glaciers, rising sea levels and other environmental changes are illustrative and important, ultimately, it's the ecological consequences that matter most," said the study's lead scientist, Jon Bergengren, in a news release.

One of the consequences, their computer model predicts, is that most of the land not covered by ice or desert will undergo at least a 30% change in plant cover — changes that will require humans and animals to adapt and often relocate.

Besides significantly altering plant life, the study predicts climate change will "disrupt the ecological balance between ... plant and animal species, reduce biodiversity and adversely affect Earth's water, energy, carbon and other element cycles," NASA said.

They identified ecologically sensitive "hot spots" that will undergo the greatest degree of species turnover, including North America's Great Lakes and Great Plains areas. They also expect dramatic changes in "ecological community types" — such as forest, grassland or tundra — throughout the northern hemisphere, particularly along the boundaries of boreal forests.

While Earth's plants and animals have evolved in response to seasonal changes and even larger climatic events like the end of the last ice age, the study said they are "not equipped" to keep up with the current pace of climate change, accelerated by human activities like agriculture and urbanization.

Bergengren said the research highlights the "global imperative" to speed up the progress of preserving biodiversity by stabilizing Earth's climate.

The researchers' simulations were based on projections in a U.N. report on climate change, which assumes greenhouse gas levels will double by 2100, then level off.

Their findings were published Friday in the journal Climatic Change.

toronto having a warmer climate would be great. no freezing rain, no snow, no ice, no cold weather, etc.

It's predicted by more than just NASA.

I can see a large increase in mining and oil production. Great stuff for the environment.

A sarcastic reponse to a sarcastic post....good on you....at first read I thought it was lost on you cause yours was more subtle...
I like the direct approach myself

I think we should just all wait for Kakato and get his definitive expertise.

The plains will be drier... Tundra will turn to swamp land... Decidious trees will be found farthur north and conifers will also be found farther north... Basically there is probally going to be a big shift

Itís all about changing and adapting that is what the human species has lived with since the beginning of time.

Humans just do not want to change their lifestyles to minimize environmental change they would rather change their lifestyle as the environment dictates.

We have the technology and the know how to build bubbled cities that control the environment within the bubbles but we have not had the need to build them although we are pretty close.

More farms are converting to vertical or greenhouse farming to maximize their crop yields per acre.

One day multi-level green houses will dot the farm country and factory farms will own the high-rise ones.

So some plant life will disappear while new ones will evolve and animal species will cease to exist while other new ones will appear.

Thatís the way itís always been and thatís the way it will always be.

We have to remember that change brings new opportunities and with that you canít go wrong.
