A Quote by John M. Grunsfeld
Here on Earth, we're exposed to asteroids hitting the Earth, eventual changes in the Sun, changes in the Earth's climate, things we're doing to the Earth's climate. If we want to survive, we need to become a multi-planet species. That's further down the road, but the first wave is going to be the explorers.

Climate has always changed. It always has and always will. Sea level has always changed. Ice sheets come and go. Life always changes. Extinctions of life are normal. Planet Earth is dynamic and evolving. Climate changes are cyclical and random. Through the eyes of a geologist, I would be really concerned if there were no change to Earth over time. In the light of large rapid natural climate changes, just how much do humans really change climate?
Earth walks on Earth, Glittering in gold; Earth goes to Earth, Sooner than it wold; Earth builds on Earth, Palaces and towers; Earth says to Earth, Soon, all shall be ours.
All things belonging to the earth will never change-the leaf, the blade, the flower, the wind that cries and sleeps and wakes again, the trees whose stiff arms clash and tremble in the dark, and the dust of lovers long since buried in the earth-all things proceeding from the earth to seasons, all things that lapse and change and come again upon the earth-these things will always be the same, for they come up from the earth that never changes, they go back into the earth that lasts forever. Only the earth endures, but it endures forever.
The Earth is the Lord. Everybody walks on the earth. And nobody respects the Earth. Everybody who walks on the earth, shits on the Earth. Spits on the Earth. Don't respect the Earth. So the Earth didn't like it. So the Earth call for a revolution. And the earth is fighting back. The Earth call for a revolution. The Earth call for justice. And the Earth get justice. 'Cause the Earth release ganja. The Earth release herbs.
Changing the asteroid's velocity changes the time when the asteroid crosses Earth's orbit. After all, just because it crosses Earth's path doesn't mean there is necessarily going to be a collision. It has to cross Earth's path when the Earth is right there.
Our climate is changing. The Earth's climate has, in fact, warmed by 1.1 to 1.6 degrees Fahrenheit since the industrial revolution. People look at this and say: Oh, that is not very much. In fact, it is very much, and it changes the dynamic. It impacts species. It kills some. It diminishes the carbon sink of the ocean. It does a number of things.
Variable behaviour of the sun is an obvious explanation, and there is increasing evidence that Earth's climate responds to changing patterns of solarmagnetic activity. ... If you look back into the sun's past, you find that we live in a period of abnormally high solar activity. ... It's a boom-bust system, and I would expect a crash soon. ... Having a crash would certainly allow us to pin down the sun's true level of influence on the Earth's climate. Then we will be able to act on fact, rather than from fear.
The earth has continued to change, from rapid climatic changes that have caused the glaciers and the ice sheets to basically bulldoze the landscape and cause species compression in the tropics and cause mass species extinction - you know, all these huge changes. In terms of evolution, every species is doomed to eventual extinction. The natural world is constantly changing. So, to deal with "environmental problems," in quotes, totally misses the issue. That is not the way we want to define our problem if we're going to find our solution.
Please remain calm: The Earth will heal itself - Climate is beyond our power to control...Earth doesn't care about governments or their legislation. You can't find much actual global warming in present-day weather observations. Climate change is a matter of geologic time, something that the earth routinely does on its own without asking anyone's permission or explaining itself.
I'd bet almost anything that life from another planet, if formed independently from life on Earth, would be more different from all species of Earth life than any two species of Earth life are from each other.
When we escape from this earth, do we suppose we are going to heaven? Do you suppose you are going to the earth that Adam came from? that Eloheim came from? where Jehovah the Lord came from? No. When you have learned to become obedient to the Father that dwells upon this earth, to the Father and God of this earth, and obedient to the messengers He sends-when you have done all that, remember you are not going to leave this earth. You will never leave it until you become qualified, and capable, and capacitated to become a father of an earth yourselves.
Smile O voluptuous coolbreathed earth!
Earth of the slumbering and liquid trees!
Earth of departed sunset! Earth of the mountains misty-topt!
Earth of the vitreous pour of the full moon just tinged with blue!
Earth of shine and dark mottling the tide of the river!
Earth of the limpid gray of clouds brighter and clearer for my sake!
Far-swooping elbowed earth! Rich apple-blossomed earth!
Smile, for your lover comes!
Just as Mars - a desert planet - gives us insights into global climate change on Earth, the promise awaits for bringing back to life portions of the Red Planet through the application of Earth Science to its similar chemistry, possibly reawakening its life-bearing potential.
It's very clear that global climate change is occurring on earth, but it's also been very clear that that has always happened on earth. We've always had a changing climate on earth. We all know about ice ages. We know when our continent was covered with ice sheets. We know glaciers come and they go. It puzzles me that people forget that.
The health of our home planet and the survival of our species will only be secured through the use of space resources and the expansion of Earth's economic sphere to the Moon and beyond. Creating an off-Earth economy and multi-planet civilization will safeguard the long term prospects of humanity.
I believe the earth's climate is changing, but I think it's changing for natural variation reasons and I think mankind has been adapting to climate as long as man has walked the earth.
