About fifty million years ago...geological evidence indicates CO2 levels were several thousand ppm, much higher than now. And life flourished abundantly.
The concentration of atmospheric carbon dioxide has changed greatly since fossilized life began on Earth nearly 600 million years ago. In fact, there is only 1/19 as much CO2 in the air today as there was 520 million years ago. That high CO2 was hardly the recipe for disaster.
Changing the world's oceans to increase their uptake of CO2, as other geoengineering solutions propose, is equally dangerous, as the increased resulting acidity of the oceans kills tiny crustaceans, such as krill, that are the basis of the pyramid of life on the planet as we know it.
Many people believe the whole catastrophe is the oil we spill, but that gets diluted and eventually disarmed over time. In fact, the oil we don't spill, the oil we collect, refine and use, produces CO2 and other gases that don't get diluted.
If we don't start thinking big about the CO2 problem, we may miss our opportunity to stop a climate runaway that will trash the habitable parts of the earth.
C'mon kids! Wake up and smell the CO2! Take over your administration building, occupy your university president's office, or storm in on the next meeting of your college's board of trustees until they agree to make your school carbon neutral.
Concentration of greenhouse gases, especially CO2, have increased substantially since the beginning of the industrial revolution. And the National Academy of Sciences indicates that the increase is due in large part to human activity.
Absolutely love the new campaign from the Optimum Population Trust: do your bit for addressing climate change by having fewer children - or even no children. The lifetime CO2 emissions of a UK citizen amount to 750 tonnes (the equivalent - apparently - of 620 return flights between London and New York), so the extra 10 million by which our population will rise between now and 2074 will, over their lifetimes, emit around 7½ billion tonnes of CO2..."births averted" is probably the most single most substantial and cost-effective intervention that governments could be using
CO2 is a pollutant? Tell that to the plants.
I believe the earth gets warmer, and I also believe the earth gets cooler, and I think history points out that it does that and that the idea that man through the production of CO2 which is a trace gas in the atmosphere and the manmade part of that trace gas is itself a trace gas is somehow responsible for climate change is, I think, just patently absurd when you consider all of the other factors.
Rush Limbaugh is beginning to look more and more like Mr. Big, and at some point somebody's going to jam a CO2 pellet into his head and he's going to explode like a giant blimp. That day may come.
By using vertical space more effectively, you not only make more room for greenery but shorter commutes also mean less pressure on CO2 emission problems and by freeing up time now spent on unproductive commuter trains, people would have more options in their lives.
CO2 emissions have been increasing, but the rise in air temperature stopped around 2001. Climate change is due in large part to naturally occurring oscillations.
Weather patterns over the next 20 or 30 years are going to be determined by the amount of CO2 that is up there now
Attributing global climate change to human CO₂ production is akin to trying to diagnose an automotive problem by ignoring the engine (analogous to the Sun in the climate system) and the transmission (water vapour) and instead focusing entirely, not on one nut on a rear wheel (which would be analogous to total CO2) but on one thread on that nut, which represents the human contribution.
The majority of humankind does not accept this system, despite claims of worldwide support. Even with Russia's ratification, 75% of the world's CO2 is emitted by, 68% of the world's GDP is produced in, and 89% of the world's population live in countries that are not handcuffed by Kyoto's restrictions. Like fascism and communism, Kyotoism is an attack on basic human freedoms behind a smokescreen of propaganda. Like those ideologies of human hatred, it will be exposed and defeated.
NASA's Aqua satellite is showing that water vapor, the dominant greenhouse gas, works to offset the effect of carbon dioxide - CO2. This information, contrary to the assumption used in all the warming models, is ignored by global warming alarmists.
If you didn't auction the [CO2] permits, it would represent the largest corporate welfare program that has ever been enacted in the history of the United States. All of the evidence is that what would occur is that corporate profits would increase by approximately the value of the permits.
In the European Union, a fleet average of 95 grams of CO2 per kilometer will be permitted in 2020. This corresponds to fuel consumption of about four liters (per 100 kilometers; about 59 mpg). We have to continue reducing the fuel consumption of our vehicles and offer hybrid and electric vehicles, or else we will be unable to achieve these values.
Statistics compiled by the German Federal Motor Transport Authority highlight how successfully we have reduced fuel consumption. A few years ago, the CO2 emissions for the BMW brand were at well over 200 grams per kilometer. In 2009, that number was at 159 grams. This puts us below our direct competitors.
Naturally, we will continue to offer very powerful vehicles in the future. Nevertheless, no other manufacturer has reduced the CO2 emissions of its fleet as substantially as the BMW Group.
Beneath the ocean surface, bad things are happening. Increasing CO2 makes ocean water more acid, and that threatens to dissolve the shells of some ocean animals. Ouch, how'd you like to have your shell dissolve?
We the people, so to speak, need to realize that if we can keep ourselves fed, we might get through this long dark tunnel of power down, and mitigate the consequences of CO2.
What is the environmental policy of the Republican Party? When I ask that question, I get a blank stare, if I'm president of the United States, we're going to address climate change and CO2 emissions in a business-friendly way.
A billion homo sapiens are added every 11 years to the planet. The hypertrophy of a single species pushes other life-forms out of bed and into extinction. The decline of biological diversity is real and severe. The alarming loss of soil fertility, forest cover, and coral reef viability and the release of fossilized CO2 that nature put away 300 million years ago in its march toward greater diversity - all these "losses" and many others are the result of one life-form annihilating other life-forms in its immoral confusion of "dominion" with "domination."
