For continuing to bring forth the important information well beyond the shiny object of the day. WE can accomplish this, it has been known for a long time now how simple things like family planning can have giant impacts on our Earth.

Cheap clean energy became a reality faster than anyone expected, let that be an example of what can be accomplished when WE just push ahead toward a unified goal. Nothing should be done out of fear — I have been talking about that for a while. There are some interesting concepts highlighted in this article, some that I have been dabbling with myself as I experiment with scaling back my own personal footprint on the planet. However, in and of themselves, I have to hold onto my pessimism that they can change the trajectory we are on when it comes to reversing scary things like climate change.

This substitution logic ignores the reality that the substitute will also impact the ecosystem in some way as well.

Perhaps it will not be in the same way that the original method did, but it will have an impact. And as the economy continues to grow, the impacts will grow proportionally. And increasing efficiency usually means more to invest in growth needed to produce more stuff. And converting sunlight to electricity via a solar panel in and of itself does not release greenhouse gases, but building the new solar infrastructure will require mining of materials like sand, aluminum and copper, which will more than likely still require the use of fossil fuels to power the mining equipment and convert the raw materials into usable panels.

Building the solar farms will require land to place the panels on, and this land will not be available for the plants and animals or people that used to live or grow there. How many solar panels will we need and how much land will be needed to place them on and where will all this land come from? I also think it is an error to assume that releasing large amounts of propane or ammonia into the atmosphere to replace fluorocarbons would not have some future affect; in the same way it is naive to assume that releasing large amounts of carbon dioxide or methane into the atmosphere would not have an effect on climate.

And making lightbulbs more efficient, only means people have more money to install more lights that can now be turned on for less money.

I believe that climate change is a symptom like other symptoms of dead zones in the oceans, impaired rivers and lakes, or extinctions of large number of plant and animal species of how our culture sees itself in relation to the planet, and how that appearance influences how we interact with the ecosystems that make up the planet. It may give an initial appearance of making them go away, but in the end the failing system that drives it all will show though the falling paint.

I think at the core what is needed first is that we need to revise this view of how we see ourselves in relation to the planet. A much more realistic, but perhaps still naively simplistic model would be to at least admit that we live on planet with finite dimensions. Human beings and human society is simply one part of many complex systems that depend on this planet in order to exist.

And that allowing an economic system that requires continuous growth to dominate our behaviors on this finite planet is like waiting for a pipe-bomb to explode in a closed room. It will take a re-evaluation of our relationship to the planet and how we live on it. It will take us to stop asking what is it that we want from our economic markets, and instead ask what is that we need to thrive on this planet we call home. Jumping on the band wagons of substitution or more efficient technologies will only hasten our fall over the upcoming cliff.

The earth has been slowly warming since the end of the Little Ice Age. It will cool again as it has several times in the past. You must be logged in to post a comment.

The IPCC operates by consensus. Accusations to the contrary are simply an attempt to re-write history. CO2 limits won't cool the planet, but they can make the difference between continued accelerating global warming to catastrophic levels vs. Natural cycles superimposed on a linear warming trend can be mistaken for step changes, but the underlying warming is caused by the external radiative forcing. All of the statements made in the IPCC report regarding the figure in question are correct and supported. Ljungqvist's temperature reconstruction is very similar to other reconstructions by Moberg and Mann.

Removing CO2 would cause most water in the air to rain out and cancel most of the greenhouse effect. Loehle and Scafetta's paper is nothing more than a curve fitting exercise with no physical basis using an overly simplistic model. Many thanks to Dr. The Consensus Project Website.

The Physical Science Basis. Kilimanjaro's ice loss is due to land use" Most glaciers are in rapid retreat worldwide, notwithstanding a few complicated cases. Climate reacts to whatever forces it to change at the time; humans are now the dominant forcing. In the last 35 years of global warming, sun and climate have been going in opposite directions. The warming trend is the same in rural and urban areas, measured by thermometers and satellites. Global warming will cause mass extinctions of species that cannot adapt on short time scales.

Satellites measure Antarctica losing land ice at an accelerating rate. The vast majority of climate papers in the s predicted warming. CO2 didn't initiate warming from past ice ages but it did amplify the warming. Net positive feedback is confirmed by many different lines of evidence. Worry about global warming impacts in the next years, not an ice age in over 10, years. Ocean acidification threatens entire marine food chains. Recent studies agree that recent global temperatures are unprecedented in the last years. A number of investigations have cleared scientists of any wrongdoing in the media-hyped email incident.

There is increasing evidence that hurricanes are getting stronger due to global warming. Al Gore's book is quite accurate, and far more accurate than contrarian books. A local cold day has nothing to do with the long-term trend of increasing global temperatures.

Extreme weather events are being made more frequent and worse by global warming. A variety of different measurements find steadily rising sea levels over the past century. Globally averaged temperature now is higher than global temperature in medieval times. Thick Arctic sea ice is undergoing a rapid retreat. The strong CO2 effect has been observed by many different measurements. Ancient natural cycles are irrelevant for attributing recent global warming to humans. The natural cycle adds and removes CO2 to keep a balance; humans add extra CO2 without removing any.

Rising CO2 increases atmospheric water vapor, which makes global warming much worse.

Polar bears are in danger of extinction as well as many other species. The benefits of a price on carbon outweigh the costs several times over. There are many lines of evidence indicating global warming is unequivocal. Other parts of the earth got colder when Greenland got warmer. Greenland on the whole is losing ice, as confirmed by satellite measurement.

There are multiple lines of direct observations that humans are causing global warming. Mars and Jupiter are not warming, and anyway the sun has recently been cooling slightly. There is long-term correlation between CO2 and global temperature; other effects are short-term. Mid-century cooling involved aerosols and is irrelevant for recent global warming. Global temperature is still rising and was the hottest recorded.

When CO2 was higher in the past, the sun was cooler. Early 20th century warming is due to several causes, including rising CO2. The most recent satellite data show that the earth as a whole is warming.

Aerosols have been masking global warming, which would be worse otherwise. A cold day in Chicago in winter has nothing to do with the trend of global warming. El Nino has no trend and so is not responsible for the trend of global warming. Most glaciers are in rapid retreat worldwide, notwithstanding a few complicated cases. Multiple sets of independent observations find a human fingerprint on climate change.

We see a clear "short-term hot spot" - there's various evidence for a "long-term hot spot".

Can global warming really be reversed? Maybe so, and Paul Hawken shows how

Weather and climate are different; climate predictions do not need weather detail. The 2nd law of thermodynamics is consistent with the greenhouse effect which is directly observed. The greenhouse effect is standard physics and confirmed by observations. Those who contribute the least greenhouse gases will be most impacted by climate change. Evidence is building that net cloud feedback is likely positive and unlikely to be strongly negative.

Sea level rise is now increasing faster than predicted due to unexpectedly rapid ice melting. The oceans are warming and moreover are becoming more acidic, threatening the food chain. Direct measurements find that rising CO2 is trapping more heat. Humans emit times more CO2 than volcanoes. When Greenland was 3 to 5 degrees C warmer than today, a large portion of the Ice Sheet melted. Methane plays a minor role in global warming but could get much worse if permafrost starts to melt. Excess CO2 from human emissions has a long residence time of over years.

CO2 levels are measured by hundreds of stations across the globe, all reporting the same trend. Multiple lines of independent evidence indicate humidity is rising and provides positive feedback.

Arguments from Global Warming Skeptics and what the science really says

Jupiter is not warming, and anyway the sun is cooling. Hundreds of flowers across the UK are flowering earlier now than any time in years. CO2 is increasing rapidly, and is reaching levels not seen on the earth for millions of years. The 'decline' refers to a decline in northern tree-rings, not global temperature, and is openly discussed in papers and the IPCC reports. Warming leads to increased evaporation and precipitation, which falls as increased snow in winter. The sun has not warmed since and so cannot be driving global warming. The ocean is absorbing massive amounts of CO2, and is becoming more acidic as a result.

Monckton used the IPCC equation in an inappropriate manner. An Independent Review concluded that CRU's actions were normal and didn't threaten the integrity of peer review. The actual data show high northern latitudes are warmer today than in Antarctic sea ice has grown in recent decades despite the Southern Ocean warming at the same time.

Humans are small but powerful, and human CO2 emissions are causing global warming. Microsite influences on temperature changes are minimal; good and bad sites show the same trend. If the dropped stations had been kept, the temperature would actually be slightly higher. Scientific studies have determined that current technology is sufficient to reduce greenhouse gas emissions enough to avoid dangerous climate change.
