Global warming – What role does water vapor really play?

Scientists say man-made CO2 causes global warming; climate skeptics insist that water vapor is responsible. Here’s why both assumptions are true.

Here are the perfect ingredients for a conspiracy theory: water vapor is the most important factor influencing the greenhouse effect but doesn’t feature on the UN’s list of greenhouse gases responsible for anthropogenic global warming.

Critics of the idea of man-made global warming love this simple fact and have turned it into one of their most potent arguments to sabotage decisive climate action.

So why doesn’t the UN’s climate body the International Panel on Climate Change (IPCC) list water vapor as a greenhouse gas? It’s because water vapor does not by itself increase temperatures. It amplifies already occurring warming.

Water vapor’s role in the Earth’s climate system is defined by the very short time it remains in the atmosphere and actively traps heat. While additional CO2 from factories or airplanes can remain in the atmosphere for centuries, extra water vapor will only remain a few days before raining down as water.

The concentration of water vapor in the atmosphere is in equilibrium. The atmosphere can only hold more water vapor if overall temperatures increase. So a small warming effect caused by human CO2 emissions will increase the amount of water vapor in the atmosphere.

The added water vapor leads to even more warming, thus amplifying the CO2 warming effect. Water vapor follows temperature changes, it doesn’t cause or, as climatologists say, ‘force’ them. As a feedback effect, water vapor is comparable to a car’s turbo charger that increases a motor’s power.

However, the amount of water vapor in the atmosphere changes regionally. While there is virtually no water vapor above deserts or the Arctic and Antarctic regions, the air above the equator can consist of up to four percent water vapor.

In humid equatorial regions, where there is already a strong natural greenhouse effect, additional CO2 and water vapor have little impact on local climate. The opposite is true in cold, dry places, which is one reason why warming is much more pronounced in Polar regions.

CO2: Endless warming

Carbon dioxide is the number one reason for man-made climate change. But what is carbon dioxide, and why is it harmful?

Concentration matters

Regional differences aside, the atmosphere contains on average only 0.4 percent of water vapor and ten times less CO2. This relatively small concentration is another argument often cited to refute the idea of man-made global warming. How can CO2 cause rising temperatures, skeptics demand, if it only accounts for 0.04 percent of the atmosphere?

Again the riddle is solved easily.

Oxygen and nitrogen are the most abundant elements in the Earth’s atmosphere and make up 99 percent of it. But neither of the two gases traps or emits heat.

This is why water vapor is responsible for most of the natural greenhouse effect. Scientists estimate that without water vapor average temperatures would be up to 30 degrees Celsius lower. CO2, on the other hand, is responsible for a much smaller but still substantial amount of the natural warming effect.

If things remain like this, we could continue living on a cozy, warm planet. But too much of a good thing is often bad. CO2 levels have increased from 0.028 percent of the atmosphere to about 0.04 percent since the Industrial Revolution. This has led to a temperature increase of about 0.7 degrees Celsius so far.

About half of this warming could be due to feedback warming from water vapor, estimates the IPCC. But it would not have happened without the added CO2 pumped into the atmosphere. CO2 is the guy robbing the bank, water vapor is just the getaway driver.

New Report: Man-made Global Warming Is a Farce

Written by Rebecca Terrell

New Report: Man-made Global Warming Is a Farce

The notion of the “new normal” of extreme weather is a farce, according to a recent report by the environmental group Committee for a Constructive Tomorrow (CFACT). Extreme Weather Report 2012 was presented at the latest UN Climate Conference in Doha, Qatar, but the only press this landmark study received was when British politician and author Lord Christopher Monckton was kicked out of the conference for presenting it.

The report is actually a massive compilation of scientific studies and news articles from both public and private sources, including the National Oceanic and Atmospheric Administration (NOAA). Together they indicate claims of “global warming,” “climate change” and “climate disruption” are nothing but a ruse to usher in massive carbon taxes and crippling regulations. Like Pavlov’s dog, politicians are conditioned to react to any harsh weather event by drooling for higher taxes, notes the study. Naturally, delegates at the UN conference were not interested in the conclusions of the CFACT study.

The Pavlov analogy is appropriate, nevertheless, as this small sampling of items from the report illustrates:

• Extreme Weather Events are Killing Fewer People Than Ever Before — Reason Foundation, September 22, 2011.

• Recent historically low global tropical cyclone activity: In the past 5-years, global tropical cyclone activity has decreased markedly — Geophysical Research Letters, 2011.

• Downward trend in strong (F3) to violent (F5) tornadoes in U.S. since 1950s — former NASA scientist Dr. Roy Spencer, May 24, 2011.

• Drought Trends, Estimates Possibly Overstated Due to Inaccurate Science: Study suggests that there has been little change in drought over the past 60 years — CBS reporting on findings published in the journal Nature, November 19, 2012.

• Are US Floods Increasing? The Answer is Still No: A new paper out today shows flooding has not increased in U.S. over records of 85 to 127 years — University of Colorado environmental studies professor Roger Pielke, Jr., October 24, 2011.

• “These recent U.S. ‘extremes’ were exceeded in previous decades…. The expression of ‘worse than we thought’ climate change as documented in [James] Hansen’s OpEd does not stand up to scrutiny.” — Alabama State Climatologist John R. Christy, Ph.D., in testimony before the House Energy and Power Subcommittee, September 20, 2012.

Other citations show the hypocrisy of climate alarmists such as Al Gore, who is on record in 2009 blaming global warming for vanishing snow and ice even at Earth’s poles. A mere two years later he published on his blog “increased heavy snowfalls are completely consistent with what [scientists] have been predicting as a consequence of man-made global warming.” Doha delegates were sure to feel that sting of reproach since the UN’s Intergovernmental Panel on Climate Change (IPCC) published warnings in 2007 in its Fourth Assessment Report (AR4) of “fewer cold outbreaks” and “fewer, shorter, less intense cold spells/cold extremes in winter.” Northern Hemisphere countries have endured unusually harsh winters since AR4 hit the newsstands.

Perhaps the most provocative citation in the report is the November 29 open letter from 125 scientists to UN Secretary-General H.E. Ban Ki-Moon, rebuking the UN for its claims that mankind is responsible for suffering caused by extreme weather events. “The hypothesis that our emissions of CO2 have caused, or will cause, dangerous warming is not supported by the evidence,” noted the authors, who also begged, “We ask that you desist from exploiting the misery of the families of those who lost their lives or properties in tropical storm Sandy by making unsupportable claims that human influences caused that storm. They did not.”

The letter went on to point out NOAA’s State of the Climate in 2008 report declared it would take 15 years of no observed warming to prove climate models and alarmist predictions wrong. Yet the U.K. Met Office recently reported “no statistically significant global warming for almost 16 years,” during a time when NOAA says atmospheric carbon dioxide concentrations rose by nearly nine percent and now make up 0.039 percent of the atmosphere.

Mark Morano of Climate Depot, who compiled the CFACT report, summed up the nature of popular climate science on Fox News (see video below): “Mayor Bloomberg said we need to take immediate action to prevent bad weather. This has now reached the level of the Mayan Calendar and Nostradamus. The New York Times has a picture of the Statue of Liberty under water and warning of the end times. This is not science! This is doomsday stuff of the Mayan calendar, and we have no business masquerading it as science.”

Hong Kong’s hollow leadership

Sunday, 10 March, 2013, 2:43pm

Comment›Insight & Opinion

HONG KONG

Sin-ming Shaw

Hong Kong’s Chief Executive Leung Chun-ying has been dogged by scandal from his first days in office, and his personal integrity is routinely impugned by much of the public. So it is no surprise that his popularity is plummeting.

Leung has only himself to blame. He seems incapable of connecting with ordinary Hong Kong citizens, instead coming across as a shifty politician who often dodges direct questions, offers vague answers, and evades responsibility for major failings by apologising for minor shortcomings.

Leung staked his reputation on being able to tame Hong Kong’s absurdly inflated property market, and has failed miserably. Indeed, Hong Kong is now the most expensive city on the planet. It takes at least 13.5 years of mean household income to buy an average flat, according to one recent international survey. The comparable figure for London and New York is 7.8 years and 6.2 years, respectively.

Treating the civil service as a potential enemy was clearly stupid, as only the civil servants know how the government actually works

Rising property prices are making middle-class flat owners multi-millionaires, while their children – even with a good university degree – can hardly afford private housing without parental help. Leung has advocated that young people leave Hong Kong to work in less expensive countries.

Leung came into his job with a self-destructive attitude. Like his mentor, Tung Chee-hwa, Hong Kong’s first chief executive after its return to China, Leung harbours a deep antipathy toward the British and the professional civil service, a legacy of colonialism. He adheres to the Maoist idea that a country consists of “the people” and “enemies” (never mind that he was the youngest and first Chinese partner in a British property-surveyor firm in Hong Kong, and that Tung studied nautical engineering in the United Kingdom).

But treating the civil service as a potential enemy was clearly stupid, as only the civil servants know how the government actually works. Neither Tung nor Leung had any operational government experience, which was most clearly demonstrated in their indifferent attitude toward public appointments. The anti-corruption police arrested Mak Chai-kwong, Leung’s first Secretary of Development, only 12 days after he was appointed. His successor, Paul Chan Mo-po, was soon exposed as a one-time owner of slum housing.

The information that undermined both officials had been buried deep in official documents, and could have surfaced only because someone, or some group, in the civil service with access decided that it would be best to leak it. In Tung’s administration, two cabinet secretaries also had to quit following damaging disclosures. With a couple of notable exceptions, the mediocrity of most of Leung’s appointees elicited sighs even from his political allies.

The same incompetence is at the root of his failure to deflate the property bubble. While he has announced grandiose plans to increase the future supply of land for development, and has hiked the stamp duty twice, the market has figured out that he does not understand that he needs to manage expectations by removing obstacles in the current development pipeline. His measures have increased prices while shrinking the number of transactions – precisely the opposite of what is needed.

One major roadblock that Leung fails to appreciate is caused by an obscure 1981 UK Privy Council ruling, Hang Wah Chong Investment Co. Ltd v. Attorney General of Hong Kong, which gave the government unlimited authority to behave as a revenue-maximising private monopolist. Thus empowered, the civil service has been behaving without regard to the public interest, as delays shrink supply while boosting prices. A substantial amount of floor space would have been available already if government authority were exercised responsibly.

Yet the same law could allow the Chief Executive to instruct the civil service to act to minimise social damage. Maximising public revenue is not always consistent with the goal of social and economic stability. After all, Hong Kong is facing a clear and present danger that the property bubble will end in tears for many.

Dissatisfaction with this state of affairs is not confined to the powerless. Victor Li Tzar-kuoi, the son of Hong Kong’s most powerful property baron, Li Ka-shing, astonished the public recently, saying in court testimony that it was a “painful experience” to deal with the government’s imperious Urban Renewal Authority.

Another roadblock is the Hong Kong dollar’s exchange-rate peg to the US dollar under the antiquated currency-board arrangement, a colonial relic still used by Gibraltar, the Falkland Islands, and St Helena (territories with a combined population of roughly 40,000). Under this system, the Federal Reserve in Washington, DC, sets Hong Kong’s interest rates and money supply.

The mantra since the handover to China in 1997 has been that this system has served Hong Kong well. But the high rate of asset inflation in Hong Kong is due partly to an undervalued currency, set at HK$7.8 to US$1 since 1983 (though allowed to trade within a narrow band between 7.75 and 7.85 since 2005). Market forces have set the real effective exchange rate by jacking up asset prices.

Hong Kong, a trading economy par excellence, thrives on market forces. Yet its policymakers remain frozen on the issue of the exchange rate. The betting in Hong Kong today is that, unless Leung can somehow reboot his administration, he is likely to follow Tung in leaving office before his term expires.

Chance to host Formula E electric car race missed as pollution soars

Chance to host prestigious Formula E event for electric vehicles is missed on same weekend that near-record levels of smog are recorded

As pollution levels approached the worst ever recorded in Hong Kong, the government has snubbed a bid to bring one of the world’s most environmentally friendly and high-profile sporting events to the city.

The air pollution index at the roadside station in Causeway Bay peaked at 202 yesterday, the second highest level since recordings began 18 years ago.

Readings taken in Central and Mong Kok reached highs of 182 and 146 respectively.

Other stations in Hong Kong also recorded very high levels, and the Environmental Protection Department told people to limit their activities on busy streets as roadside air pollution was severe.

But the bad news did not end there. Formula E Holdings, promoter of the Formula E Championship, also made public its preliminary list of eight cities selected to host races next year – omitting Hong Kong.

The races will feature cars powered exclusively by electric energy. Hong Kong had been regarded by organisers as an ideal venue, but the government was not interested.

“Hong Kong will not be hosting a race next year. We can only hope the government will be more motivated in the future,” said Alejandro Agag, chief executive of Formula E.

“We were just left waiting and had to make a decision.”

Agag said his organisation provided government consultants with all the relevant details – such as the cost and how long streets would need to be closed – but heard nothing back. “It’s hard to consider Hong Kong as a venue when they don’t express their interest or contact us,” he said.

The lawmaker for the tourism sector, Paul Tse Wai-chun, said the government had missed out on an opportunity to improve the city’s image internationally.

“It would have been perfect to announce we were hosting a Formula E race here after the recent pollution problems. But all we have is even more bad publicity.”

Cities included in the Formula E preliminary calendar are London, Rome, Los Angeles, Miami, Beijing, Putrajaya (in Malaysia), Buenos Aires and Rio de Janeiro.

A spokesman for the Tourism Commission said that at this stage it was premature for them to comment on whether it was feasible for an event like Formula E to be staged in Hong Kong and whether it would receive government support.

“We work to attract mega events and activities to Hong Kong to enrich our overall tourism appeal and reinforce our status as the event capital in Asia,” he said.

Meanwhile pollution levels here are destined to remain high. Light winds mean the smog will not subside for a few days.

An Environmental Protection Department spokesman advised people with heart or respiratory illnesses to avoid staying in areas with heavy traffic.

“Everyone is advised to avoid prolonged stays in these areas and to reduce physical exertion in such areas,” he said.

Causeway Bay API soars above WHO safety guidelines

Government urged to curb vehicle emissions as calm weather lets exhaust gases linger  Environment officials came under pressure to cut vehicle emissions after dangerous pollution levels were recorded in one of Hong Kong’s busiest shopping districts yesterday.

In Causeway Bay, the air pollution index (API) hit 198, the third-highest level since recording began 18 years ago. Central’s highest reading was 187.

Those levels are described as “very high” under the city’s pollution forecast and warning system. People with respiratory or heart disease were advised to stay indoors.

In Causeway Bay, the air pollution index (API) hit 198, the third-highest level since recording began 18 years ago

The dominant pollutant in yesterday’s air was nitrogen dioxide, which comes from vehicle exhausts or reactions among various pollutants.(CTA: AND SHIPS which contribute more than 30%)

Nitrogen dioxide reached 291 micrograms per cubic metre of air at 3pm in Causeway Bay – nearly 50 per cent more than the World Health Organisation safety guideline of 200.

The level of PM2.5 – tiny particles that can penetrate deep into the lungs – was 72.4 micrograms at 3pm. The WHO’s recommended safety level is 25 micrograms, on average, over 24 hours. The city’s worst recorded roadside pollution was a “severe” API reading of 212 in Central last August.

Dave Ho Tak-yin, principal environmental protection officer, blamed calm weather for the dangerous pollution. “We expect air dispersion will remain poor and the API readings will remain at very high levels in the next couple of days,” he said.

Kwong Sum-yin, chief executive officer of the Clean Air Network, called the pollution alarming and urged the government to take prompt action.

“I hope [new measures] can be rolled out at a much quicker pace, and that steps will be taken rather than just talked about,” she said.

Officials’ top priority, she said, should be retrofitting franchised buses and ageing LPG vehicles with pollution filters.

But a spokesman for the Environmental Protection Department said the government had no timetable for seeking funding from lawmakers to subsidise bus and taxi operators for such a retrofit. (CLEAR THE AIR SAYS : “why in hell do that ? make the regulations stricter and make them comply or get off the bloody roads !)
