Snowden and NSA leaders should be brought together face-to-face for questioning in public by a congressional investigatory committee, with both parties allowed to make their points and to counter the assertions of the other. If Snowden is lying, it will come out. If the NSA is lying, it will come out.

Weather systems are natural heat engines, and like all other heat engines, both natural and artificial, they are driven not by temperature per se, but by differences in temperature between one location and another.

No one can prevent hurricanes, but prosperous communities are much better able to withstand them than poor ones.

Some conservatives say that whether it's popular or unpopular, imposing strict limits on immigration is the right thing to do, and it must be defended.

The bedrock foundation of any rational immigration policy should be to benefit America rather than benefiting potential or existing immigrants, or any other specific group, whether favorable or antagonistic to them.

In any economy, the entire population is supported by the part of it that is working. All other things being equal, it thus follows that the most attractive acquisition a society can have is a young adult, whose childhood and education has already been paid for, but whose entire working life still lies ahead.

America is a country defined by a set of ideas, and when people choose to accept those ideas, they should be able to become Americans, as fully so as any - and perhaps more so than most - regardless of how recently they or their ancestors arrived upon our shores. This is the true American tradition, which as conservatives we must defend.

Starting as a few bands of hunter-gatherers, humanity expanded the food resources afforded by the land a thousandfold through the development of agriculture.

I own a small aerospace company that does some business with the U.S. government.

The relationship between carbon consumption and human well-being is causal, not coincidental.

Carbon is the stuff of life, and it's the stuff of everything used by human society. All of our materials are made of carbon or of substances, such as steel or glass, which are produced through the utilization of carbon.

There are many elements needed to secure economic growth. Certainly, people must be politically free to innovate, invest, build, and create things, and they must be incentivized to do so by knowing they can keep the rewards for their efforts.

Human population supplies the labor necessary for the creation of wealth; carbon supplies the matter and energy.

Economic growth must be the central issue because it is only through growth that the devastating threat of national bankruptcy can be averted. Furthermore, it is only by reviving American economic growth that the West's global predominance can be sustained, and peace and freedom kept secure around the world.

Energy powers our economy, both literally and figuratively.

The more that energy costs, the less economic activity there can be.

The policy of the Obama administration is to employ regulatory strangulation to drive up the price of energy. This must be exposed and opposed for what it is: a policy of forced economic contraction.

Ireland never lacked the capacity to feed its people. During the entire 'great famine,' the island continued to produce massive amounts of beef and grain. The Irish just couldn't afford to buy any of it due to the enforcement of rack-renting, high taxation, and suppression of manufactures.

As a result of the carbon-dioxide enrichment of the Earth's atmosphere, plants are now growing faster. Furthermore, global warming lengthens the growing season and increases net rainfall.

What the world needs most for its stability, and what the U.S. needs for its national security, is economic growth, which is driven first and foremost by expanded carbon use.

Nothing could be more regressive than carbon taxes.

Nothing could do more to help the world's poor than to make fossil fuels cheap and plentiful.

Nothing could do more harm to America's national security than a carbon-restricted, depressed economy that would make funding our military impossible.

The revelation that the National Security Agency has been secretly amassing data on countless law-abiding American citizens has aroused great concern about the potential threat such an effort poses to liberty.

The issue comes down to this: The NSA metadata-collection program costs lots of money, and had funds not been expended on it, they could have been used to support other programs that might have been far more effective in saving American lives.

If we are to assess the rationality of government expenditures to protect the lives of Americans through massive domestic surveillance, we need to compare this program to others aimed at saving American lives.

Were the United States to pass a law requiring all cars to be methanol-capable flex-fuel vehicles, or simply repeal EPA regulations that prevent such conversions from being carried out privately, our immense natural-gas capacity could make a dramatic entrance into the liquid-fuel market.

The No. 1 purpose of the federal government is national defense.

The United States should give former NSA contractor Edward Snowden immunity from prosecution in exchange for congressional testimony.

The well-stuffed slave masters currently gorging themselves in Cuba's halls of power need to be held accountable.

The federal government was created to defend the United States, not to wage war upon it.

Like the producers of crops, airplanes, and books, producers of natural gas provide goods to meet the size of their available market. The larger the market, the more they can produce, and the more revenue they can obtain to cover their fixed costs and invest in future development.

The United States has the largest and best navy in the world.

Our European allies need to be able to buy our fuel, or they will fall to enemy domination.

There is nothing 'conservative' at all about Putin's cause. What he is offering is a synthetic ideology called Eurasianism, composed for him by Dugin, as a means of uniting all the anti-Western movements of the world under Kremlin control.

In what was called the second siege of Leningrad, thousands died, but Putin and his partners in crime got rich. Then Putin killed even more Russians when he had the FSB explode bombs in apartment buildings in Moscow in 1999 to give himself the pretext to seize dictatorial powers.

Putin himself made his original fortune in the early 1990s, when he stole the funds that had been entrusted to him to buy food in Europe to relieve the starvation in Leningrad that occurred during the economic collapse following the fall of the Soviet Union.

Government attempts to ban fracking should be aborted. The government should lift the burdensome regulations that have made the construction of nuclear power plants excessively expensive, thereby freeing up even more natural gas for direct use or for methanol manufacture.

The blockade against American natural-gas exports needs to be lifted, and the war on coal needs to be ended, so that, instead of being wasted to replace perfectly good coal-generated electricity, our natural-gas exports can be expanded even further.

The federal government should end its policies of economic warfare against the United States and allow our nation to develop all its energy resources to the fullest, both for domestic use and for export.

The Putin regime's income comes from oil and gas exports. If we could crash the price of these commodities, we could bankrupt the regime.

The 20th century saw three great-power confrontations. Two of them turned into total war. We lucked out on the third. Do we really want to roll those dice again?

Without Ukraine, Dugin's fascist Eurasian Union project is impossible, and sooner or later, Russia itself will have to join the West and become free, leaving only a few despised and doomed islands of tyranny around the globe.

When the government mandates that everyone must buy a product, its sellers can, and will, increase its price, potentially without limit.

Traditional Marxism attempted to argue against free enterprise by saying that capitalism causes poverty and that, therefore, socialism is necessary. That didn't work, because it was false.

The danger facing us comes not from lack of resources, but from people who insist that we have run out of resources. If you embrace their idea of a world where there is only so much to go around, then you are endorsing a program of genocide and a war of all against all.

Instead of forcing everyone to buy health insurance, Congress should pass a law protecting the uninsured from being charged more than the insurance companies are for a given service.

Western environmentalists might value their independence, but their organizations are largely donor driven, and if he wanted to, Putin could have a lot to donate.

Fewer jobs, at lower pay. That's what Obamacare means.

I run a small company with 18 employees on its payroll.
