A Quote by Richard Lindzen
Future generations will wonder in bemused amazement that the early 21st century's developed world went into hysterical panic over a globally averaged temperature increase of a few tenths of a degree, and, on the basis of gross exaggerations of highly uncertain computer projections combined into implausible chains of inference, proceeded to contemplate a roll-back of the industrial age.

I think future generations will say the late 20th century and the early 21st century was a time of great convulsions and upheavals.
One of the computer models for a four degree temperature rise would give rise to a 10 degree temperature rise in Africa. And bear in mind also that in the depth of an ice age the mean temperature drop compared to the present was five degrees.
Now the 21st century approaches and with it the inevitability of change. We must wonder if the American people will find renewal and rejuvenation within themselves, will discover again their capacity for innovation and adaptation. If not, alas, the nation's future will be shaped by sightless forces of history over which Americans will have no control.
Computer science teaches and nurtures the type of thinking that 21st century citizens will need to address 21st century issues. We cannot know with any certainty what those challenges will be, but we can arm our students with the tools needed to address them.
Earlier this week ... scientists announced the completion of a task that once seemed unimaginable; and that is, the deciphering of the entire DNA sequence of the human genetic code. This amazing accomplishment is likely to affect the 21st century as profoundly as the invention of the computer or the splitting of the atom affected the 20th century. I believe that the 21st century will be the century of life sciences, and nothing makes that point more clearly than this momentous discovery. It will revolutionize medicine as we know it today.
Market capitalism survived and prospered after the boom-bust industrial revolution of the 19th century, and the Great Depression and world wars of the 20th century. It will recover from the financial panic of 2008-09 and Obamanomics.
You really do have to wonder whether a few years from now we’ll look back at the first decade of the 21st century — when food prices spiked, energy prices soared, world population surged, tornados plowed through cities, floods and droughts set records, populations were displaced and governments were threatened by the confluence of it all — and ask ourselves: What were we thinking? How did we not panic when the evidence was so obvious that we’d crossed some growth/climate/natural resource/population redlines all at once?
When future generations look back on the global-warming scare of the past 30 years, nothing will shock them more than the extent to which the official temperature records – on which the entire panic ultimately rested – were systematically “adjusted” to show the Earth as having warmed much more than the actual data justified.
Just because a company's future is highly uncertain doesn't mean an investment in it is risky. In fact, some of the best potential investments are highly uncertain but have little risk of permanent capital loss.
It's nice to know there are some things in early 21st-century post-industrial culture that don't change very fast. I am one of those.
The 21st century is dominated by networks because the introduction of the information age, we can suddenly create, free flow these globally distributed, organic, shaped networks of individuals.
The simple fact is that, since the beginning of this century, the average global temperature has flatlined; indeed, over the past 18 months it has fallen back, and according to the satellite measurements of temperature, it is now basically back at the level it was in 1979, when such measurements started to be taken.
Globally, emissions may have to be reduced, the scientists are telling us, by as much as 60% or 70%, with developed countries likely to have to make even bigger cuts if we're going to allow the developing world to have their share of growing industrial prosperity...The Kyoto Protocol is only the first rather modest step. Much, much deeper emission reductions will be needed in future. The political implications are mind-blowing.
So far the earth has warmed about a degree Fahrenheit globally averaged. That doesn't seem like an enormous amount but it's unlike what we would have expected twenty years ago.
Our early 21st century civilization is in trouble. We need not go beyond the world food economy to see this. Over the last few decades we have created a food production bubble-one based on environmental trends that cannot be sustained, including overpumping aquifers, overplowing land, and overloading the atmosphere with carbon dioxide.
The transition to a low-carbon economy will be one of the defining issues of the 21st century. This plan sets out a route-map for the UK's transition from here to 2020...every business, every community will need to be involved. Together we can create a more secure, more prosperous low carbon Britain and a world which is sustainable for future generations.
