Jamais Cascio Quotes

My dad joined Langley in 1964 as a co-op student and retired in 2004 an internationally respected climate scientist.

The science is clear that there is an increase in the amount of CO2 in the atmosphere. What is not clear from the science is how much of that increase is caused by human activity; and what also is not clear is what impact those increases have on the climatic cycle.

Computer modelling for weather forecasting, and indeed for climate forecasting, has reached its limits.

The science linking the increased frequency and severity of extreme weather to the climate crisis has matured tremendously in the last couple of years.

Young people, those who think they're experts in science, there's no doubt. They just believe it, and so there has to be an explanation - and whatever man is doing has caused the jet stream to slow down, and that is permitting the polar vortex.

One can't predict the weather more than a few days in advance.

Among all of our uncertainties weather is the most basic. We can’t live without it and we can’t control it.

Our climate is always changing.

The climate is changing; I don't think you can deny that. But climate has always changed.

The climate is changing, but the question is how much - and to what extent human factors are contributing to that.

We see something change in our climate and we blame ourselves ... I don't think we understand what happens. We can watch it happen on the (climate) models, we know it happens, but we don't know for sure how it happens.

It is almost possible to predict one or two days in advance, within a rather broad range of probability, what the weather is going to be; it is even thought that it will not be impossible to publish daily forecasts, which would be very useful to soci.

The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.

The weather records of the U.S.A. are the best kept and most accessible in the world, thanks to consistent government/military taxpayer support. There are longer European data sets, but the U.S.A. data is enough to forecast major extreme events.

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.

We need to remind ourselves that our ultimate goal is not to reduce greenhouse gases or global warming per se but to improve the quality of life and the environment. We all want to leave the planet in decent shape for our kids. Radically reducing greenhouse gas emissions is not necessarily the best way to achieve that.

What most people know but don't realize they know is that the world is almost entirely solar-powered already. If the sun wasn't there, we'd be a frozen ice ball at three degrees Kelvin, and the sun powers the entire system of precipitation. The whole ecosystem is solar-powered.

The global climate is a complex interactive system, with all kinds of nonlinear feedback loops.

I've never been one to bet on the weather.

You can't say for certain what will happen to the weather in the long term.

The climate has been changing since there was a climate.

I think there is a degree of speculation that is satisfied the climate is changing.

I am saying that all predictions concerning climate are highly uncertain.

I would say that, basically, global warming is a non-problem.

Scientists will say we can't blame global warming for any single event. In a sense that's right, but the fact that the frequency and intensity of these events is increasing you can blame on global warming.
