Buzz Aldrin Quotes

As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet.

The first thing that is not obvious to people is global warming is a less-than-1% effect. It's like being shortchanged at the bank by a penny every dollar. Over a long period of time with lots of transactions, that piles up.

I'm absolutely convinced that the very small global warming we are experiencing is the result of natural causes. It's a cyclical phenomenon in the history of the Earth. The role of man is very small, almost negligible.

In the 1970s, the scare was about global cooling.

The climate has been changing since there was a climate.

Climate does fluctuate. It goes from hot to cold. We have ice ages.

Climate change is not the fault of man. It's Mother Nature's way. And sucking greenhouse gases from the atmosphere is too limited a solution. We have to be prepared for fire or ice, for fry or freeze. We have to be prepared for change.

You want calamities? What about the Ice Age?

The basic science is very well established; it is well understood that global warming is due to greenhouse gases. What is uncertain is projections about specifics in the next few decades, by how much will the climate change.

Some people call it global warming; some people call it climate change. What is the difference?

The oceans that surround the world produce 185 billion tons of CO2 per annum. Man per annum only produces six billion tons, so what could possibly be the concern?

We now know that we cannot continue to put ever-increasing amounts of CO2 into the atmosphere. Actions have consequences. In fact, the consequences of past actions are already in the pipeline. Global temperatures are rising. Glaciers are melting. Sea levels are rising. Extreme weather events are multiplying.

Ice ages have come and gone. Coral reefs have persisted.

There is no significant man-made Global Warming underway and the science on which the computer projections of weather chaos are based is badly flawed.

The number of hypotheses and theories about climate change are numerous. Quite naturally they have caught the public attention, as any proof of past climactic change points to the possibility of future climate change, which inevitably will have significant implications for global economics.

The risks brought about by climate change are a major concern. It goes without notice—unless people find out that 12 of the last 13 biggest climatic disorders have occurred in the last 10 years.

It turns out that as the climate changes, the distribution of that water is changing very fundamentally. So now we have too much, too little, wrong place, wrong time. It's salty where it should be fresh; it's liquid where it should be frozen; it's wet where it should be dry; and in fact, the very chemistry of the ocean itself is changing.

Is global warming causing more extreme weather events of greater intensity, and is it causing sea levels to rise? The answer to both is an emphatic 'no.'

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 earth's climate has been changing since God created it, with or without man. On that, we should all agree.

The earth's history over the past several million years is that for every 100,000 years, we go through a dramatic climatic cycle where we get 90,000 years of ice age and 10,000 years of a warm period. I think people today just have the expectation that we deserve a perfectly benign climate forever.

We have no choice: we must protect Arctic ice, enable it to continue to act as an essential temperature regulator for the planet, avoid the catastrophic rise in sea levels that would result from the ice melt, and stop the disappearance of permafrost releasing irreversible quantities of greenhouse gases back into the atmosphere.

Climates always change. The question is, how are we going to adapt to climate change? Now, it may be true that we are accelerating it inadvertently by messing with our atmosphere, but regardless of that, the climate will change.

Climate change is real. Climate change is being substantially increased by humans and the carbon we put into the atmosphere. And it appears to be speeding up. If science has made any mistakes, science has been underestimating it.

Climate is always evolving, and natural disaster have always existed.
