Konstantin Tsiolkovsky Quotes

If you represent the Earth's lifetime by a single year, say from January when it was made to December, the 21st-century would be a quarter of a second in June - a tiny fraction of the year. But even in this concertinaed cosmic perspective, our century is very, very special: the first when humans can change themselves and their home planet.

We have changed our environment more quickly than we have learned how to change ourselves.

Every species becomes extinct; at some point, we will go extinct. The question is, as Homo sapiens, are we going to be able to adapt to the change that we're actually part of? We're causing such dramatic changes to the planet, so yes, you do stop and think, 'I wonder where we're headed.'

If we each take responsibility in shifting our own behavior, we can trigger the type of change that is necessary to achieve sustainability for our race or this planet. We change our planet, our environment, our humanity every day, every year, every decade, and every millennia.

Believe it or not, very little research has ever been funded to search for natural mechanisms of warming... it has simply been assumed that global warming is manmade. Climate change - it happens, with or without our help.

We're the only creature God ever created that doesn't want to adapt. We want to make it stand still. And one thing that's constant is nature is constantly changing.

Climate change is transforming the world in profound ways that continue to evolve.

I'm a staunch believer that we are in an earth cycle. There's no question the planet is changing, and the fact that the Mayans had an end date and their history talks of change, I find that fascinating.

Our conservation laws are based on static ideas about nature—not landscapes that are rapidly changing because of something humans did.

Man has evolved a mutual relationship with nature on earth, but his power to change its surface has grown so tremendously that this may become a curse instead of a blessing.

Climate change is sometimes misunderstood as being about changes in the weather. In reality it is about changes in our very way of life.

In 2007, I received a National Geographic Expeditions Council grant to go around the top of the world and talk to Arctic people about how they've been impacted by climate change.

Some global hazards are insidious. They stem from pressure on energy supplies, food, water and other natural resources. And they will be aggravated as the population rises to a projected nine billion by mid-century, and by the effects of climate change. An 'ecological shock' could irreversibly degrade our environment.

Civilization exists by geological consent, subject to change without notice.

The world is using up its natural resources at an alarming rate, and this has caused a permanent shift in their value. We all need to adjust our behavior to this new environment. It would help if we did it quickly.

The earth's biosphere could be thought of as a sort of palace. The continents are rooms in the palace; islands are smaller rooms. Each room has its own decor and unique inhabitants; many of the rooms have been sealed off for millions of years. The doors in the palace have been flung open, and the walls are coming down.

Human beings are definitely changing the planet, but how much impact they are having on climate, I don't know and I don't care.

With our evolved busy hands and our evolved busy brains, in an extraordinarily short period of time we've managed to alter the earth with such geologic-forcing effects that we ourselves are forces of nature. Climate change, ocean acidification, the sixth mass extinction of species.

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.
