A Quote by James Hansen

In view of the immense power of natural weather and climate fluctuations and the great buffering capacity of the Earth, especially the ocean, it is easy to be skeptical about whether small anthropogenic changes of atmospheric composition can have important practical impacts.

People ask: Why should I care about the ocean? Because the ocean is the cornerstone of earth's life support system, it shapes climate and weather. It holds most of life on earth. 97% of earth's water is there. It's the blue heart of the planet - we should take care of our heart. It's what makes life possible for us. We still have a really good chance to make things better than they are. They won't get better unless we take the action and inspire others to do the same thing. No one is without power. Everybody has the capacity to do something.

Sylvia Earle

A sensible climate policy would emphasize building resilience into our capacity to adapt to climate changes - whether cooling or warming; whether wholly natural, wholly man-made, or somewhere in between.

Steven F. Hayward

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.

Dianne Feinstein

There is no need for the Russian state to hold such large stakes and we do intend to put our plans into practice. It is not about whether we want it or not, it is about this being practical or not and the best timing. In general, it is practical from at least one point of view - from the point of view of structural changes in the economy.

Vladimir Putin

This influential, yet controversial idea requires that the mixture of species on Earth at any moment acts as a collective organism that continuously (yet unwittingly) tunes Earth's atmospheric composition and climate to promote the presence of life... But I'd bet there are some dead Martians and Venusians who advanced the same theory about their own planets a billion years ago.

Neil deGrasse Tyson

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?

Ian Plimer

We're facing enormous changes in our planetary life, with climate change and the adaptations that all natural systems are going to have to make to these climate changes, and so it's extremely important to bear witness to what's happening.

Alison Hawthorne Deming

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.

Robert B. Laughlin

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.

John M. Grunsfeld

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

Paul Polman

I think that an advanced planetary civilization will modify their own planets to be more stable, to prevent asteroid impacts and dangerous climate fluctuations.

David Grinspoon

I believe that climate change is real, is driven mainly by human activity and that it is driving real-world changes such as extreme weather events, hotter temperatures, rising sea levels and ocean acidification.

Jeff Van Drew

If we return abruptly to a Miocene-like climate, it's reasonable to think that we would experience a lot of extinctions, and maybe even a mass extinction in the long term. Would the life on Earth be radically different? Of course we can't say for sure, but I think a lot of it would look familiar. Like a lot of people, I worry a lot about whether marine mammals would survive, especially whales. Ocean acidification is one of the major killers in climate change events, and that makes the ocean a very inhospitable place.

Annalee Newitz

Climate changes are caused by solar radiation and other natural phenomena, so I don't worry one bit about that. Nothing we do can change anything in the climate.

Varg Vikernes

The Ocean Health Index is like the thermometer of the ocean. It will allow us to take the temperature to know what is going on at the global level, trying to integrate different impacts, including overfishing, invasive species, coastal development, and climate change.

Enric Sala

The idea that we have the capacity to change or stop the climate, I'm just skeptical.
