Is gravity affected by global warming, and will it attract an asteriod to earth?

Question

I am not science savy.

Answer 1

No gravity is affected by mass and there is no such thing as global warming as most people define it. Over th past 5 billion years, the earth has experienced many warming and cooling epochs (the Ice Ages come to mind); it is a natural phenomenon.

Answer 2

Oh my god there is some really bad science being thrown out here in some of these 'answers'. At least the Asker admits to not being science savvy.

Ok, gravity is caused by two factors - mass and density, nothing else. Global warming is an issue regarding changing weather patterns. Heating up or cooling down of the Earth will have no affect on either the planet's mass or density.

As for asteroids, we're in danger of that all the time. It has happened before and will happen again, just like super-massive volcanic eruptions. In the event of an asteroid strike, we'd actually get much, much colder due to the the debri shot into the upper atmosphere. All that dust and ash will block out sunlight, causing something akin to 'nuclear winter'.

Answer 3

In a very small way, the Earth's gravitational pull will increase if the amount of energy in the Earth system increases. Since heat is a measure of energy and energy has a mass equivalent, more heat equals more mass equals more gravity. We're talking a tiny, miniscule amount though. Probably not enough to measure, certainly not enough to pull in an asteroid or comet that wasn't already going to get attracted by the Earth's gravity without any additional global warming heat.

Answer 4

The balance of gravity can be affected.

Our current variation of seasons across the planet is due to the Earth's tilt caused by the effect of Moon's gravity.

If glaciers melt in a runaway Global Warming, the existing gravity balance of dynamic objects like Moon, Oceans, and Glaciers are distorted.

Forget about asteroids, the Moon itself can crash into Earth, or leave us for good. Either possibility will add more disasters to impact of Global Warming in isolation.

Answer 5

No, Global Warming is refering to clime and environmental changes, the gravity is a consequence of the mass and that is not changing, however it was mentioned that global warming could create a disorder that change the earth axis if this is the case maybe some other space interactions can be modified.

Answer 6

no gravity is caused by the rotation of the earth around the sun.. an asteriod would be cause by the gravitional pull from another planet swinging the asteriod inton the earth.. global warming is cause by greenhouse gasses and is unrelated to both

Answer 7

Gravity is force and is affected by masses and distances. Global warming has nothing to due with force.

Answer 8

Is global warming raising the mass of the Earth? If not, then no.

Answer 9

no, gravity is not affected by temperature, only by mass

and even if the gravity of the earth was so high that our own weight would squash us, that extra gravity would not have much affect on probability of significant asteroid strike

remember, many of the other planets have much higher gravity potentials than earth and the sun has much much much higher gravity

Answer 10

I don;t know where you live but up here in the north we're getting tired of shoveling global warming
