Dos vidanya, Apophis!

That reads almost like an article out of the Onion.

Issue:

Further studies ruled out the possibility of an impact in 2029, when the asteroid is expected to come no closer than 18,300 miles (29,450 kilometers) above Earth's surface, but they indicated a small possibility of a hit on subsequent encounters.

In October, NASA lowered the odds that Apophis could hit Earth in 2036 from a 1-in-45,000 as earlier thought to a 1-in-250,000 chance after researchers recalculated the asteroid's path. It said another close encounter in 2068 will involve a 1-in-330,000 chance of impact.

Response:

Without mentioning NASA findings, Perminov said that he heard from a scientist that Apophis is getting closer and may hit the planet. "I don't remember exactly, but it seems to me it could hit the Earth by 2032," Perminov said.

"People's lives are at stake. We should pay several hundred million dollars and build a system that would allow to prevent a collision

Him not even knowing the year we calculate the fly-by doesn't leave me feeling confident about his ability to do this right.

My worry is that we could wind up making things worse. You have to hit that thing with a pretty high level of precision to ensure the course adjustment being made won't ultimately increase the probability of impact with Earth.

Curious, I posted the exact same link at another site and it still works fine.

(fixed it, thanks)

I'm pretty sure you copy/pasted from the post output (not the post edit window) and the ellipsis got carried over here when posting. In fact, I grabbed the link from your post at that other site. :wink:

Hello Amadish,

We're already discussing that over here:

Take care.

thanks for the post, interesting information.

But it is not only about how much the Earth is warming, it is also about how fast it is warming. There have always been natural climate changes – Ice Ages and the warm intermediate times between them

Global Warming as a chain of events:
1. Permafrost: Currently the measured effect of global warming as caused by the greenhouse effect on the planet overall is approximately a 1 degree Celsius increase over the last 50 years. that one-degree of heat made you take off a sweater, segments of the Earth known as permafrost began a meltdown. Permafrost is a condition whereby sections of the Earth’s surface have remained at a temperature below freezing (0 degrees Celsius) for at least two years.
2. Tundra: Tundra describes the soil above permafrost that is frozen for most of the calendar year but thaws for allowance of small amounts of vegetation growth. Areas of Tundra throughout the world serve as sinks for absorption of massive amounts of Carbon.
3. Polar meltdown: The Next is the warming of our polar caps and oceans. An increase in overall temperature for the troposphere allows that segment of the atmosphere to absorb more water vapor. A 1% increase in water vapor is a huge increase to the overall amount of greenhouse emissions.
4. Ocean Temperature and Positive Feedback: Our oceans digest most of the carbon footprint needing to be absorbed into our ecosystem. Currently greenhouse gas emissions from production of energy and internal combustion engines results in a 36% increase in carbon dioxide over that which the planets normal balance can support. The CO2 then slightly raises the Earth’s temperature resulting in an endlessly looping progression. This situation and scenario is known as positive feedback and this is the real danger inherent as global warming.
5. Environmental cause: Not all of global warming is the result of greenhouse gases and the ensuing greenhouse effect. As the population of the earth has increased mankind has brought civilization which includes buildings, highways, land cleared for agriculture, cities built where once stood deserts. Almost everything that we build absorbs more heat than its natural predecessor. It doesn’t mean that we tear down all of our houses to plant a forest of trees and carve up the superhighways and replace them with lovely green meadows. What we do need is an awareness of our situation. We need to realize that every move we make as a result of industrialization has a corresponding consequence.

I see no relation between this and the original topic. This has been copy/pasted from at least two other websites.

I know that this will appear as a little off-topic, so I hope it will be permitted to be posted.

In my opinion, and I admit to not having much to back this up - that the members here will accept, at least. Even so, I believe the name of the asteroid has been proposed and recorded incorrectly, and really should have been 'Apopohis', rather than Apophis.

I do have my reasons for making this observation, some of which effectively extend back to ancient Egyptian theology, yet I have no way of verifying how folk in those times would have pronounced the relevant original name.
