Climate Journalists now out of line with scientists

Judith Curry has reviewed the major climate stories of 2012. She notes

The theme of these seems to be dangerous impacts of climate change, bypassing of course the issue of attribution of these events.  Maybe the big story is that a critical mass of bad weather events happened in the U.S., so we are experiencing in the U.S. another round of what we experienced post Katrina in terms of elevating concern about global warming.

The leaked draft AR5 SPM Page 3 Lines 46-47

Changes in many extreme weather and climate events have been observed, but the level of confidence in these changes varies widely depending on type of extreme and regions considered.

The leaked draft AR5 SPM Page 4 Lines 10-11

There is low confidence in observed large-scale trends in drought, due to lack of direct observations, dependencies of inferred trends on the index choice, and geographical inconsistencies in the trends

The leaked draft AR5 SPM Page 4 Lines 14-16

Tropical cyclone data provides low confidence that any reported long-term changes are robust, after accounting for past changes in observing capabilities. This is a revision from previous IPCC Assessments Reports…

Are the commentators going to come into line with the consensus of scientific opinion, or will it be the other way round? Maybe, like in the disaster movies, they will continue to insist to believe that the world only consists of USA.

For those who still think that extreme weather is still increasing, check out the Wattupwiththat “Extreme Weather” page. In particular take a look at Ryan Maue’s accumulated cyclone energy graph.

Kyoto Protocol is now dead – DNR

The first stage of the 1997 Kyoto Protocol officially comes to an end today. We should say DNR – Do Not Resuscitate

The underpinnings of the Kyoto Protocol used benefit-cost analysis to achieve a compromise solution. To achieve is goal it needed ALL of the following assumptions to be true.

  1. CO2 causing a massive increase in global warming.
  2. For that warming to have massive catastrophic consequences.
  3. For economic theory to provide a theoretical solution with benefits ≥ costs.
  4. The actual solution matches the theory.
  5. There are no unintended consequences of actual policy implementation need to be taken into account.
  6. That the Kyoto Protocol was originally estimated at being 97% useless in constraining temperature rises.

CO2 causing a massive increase in warming.

If you still believe the hype that CO2 is going to cause a massive increase in global warming, you are now at odds with the latest estimates from the IPCC. David M. Hoffer at Wattsupwiththat shows why.

Massive catastrophic consequences

Where is the evidence of accelerating sea level rise; increasing tropical storms; desertification; accelerating rate of polar ice melt; disappearing Himalayan glaciers causing water shortages; or massively reduced crop yields in Africa leading to famines? Where is all the talk of reaching climate “tipping points”, which must be avoided at all costs? You will not find them in the latest AR5 SPM, because there is no half-decent scientific evidence to support these claims,

Support from economic theory?

William Nordhaus, the world’s leading climate change economist, calculates that the benefit-cost ratio is 1/7. Nordhaus accepts the first two points, but still calculates that on economic terms you should not touch the scheme with a bargepole. More recently, Dieter Helm has described emissions trading schemes as the most expensive way of reducing emissions. Both advocate a carbon tax.

Actual scheme matches theory

Kyoto proposed that countries adopt an emissions trading scheme. In the EU it did not work because credits were issued at too low a cost.

Unintended Consequences

The emissions trading schemes have essentially collapsed, mostly because there has been no commitment to extend Kyoto. Given that there have been numerous fraud scandals from the large through to the small, this is no bad thing. The schemes are open to abuse, yet the investment banks that run them make billions of dollars annually.

Kyoto is Limited

The Kyoto Protocol, if it has been fully implemented would have only constrained a projected 2 celsius rise in CO2 by 2050 by just 0.06 degrees. At the outset policy-makers knew it would be 97% worthless, yet still went ahead anyway.

Continued support for Kyoto must disregard the latest opinions of climate science, economic theory, and the practical problems of public policy-making. Continued support must implicitly support the investment banks to make profits at the expense of ordinary folk, and numerous fraudsters. You must also support a policy that was pretty close to useless at the outset, and now is positively harmful.

AR5 First Order Draft Summary for Policymakers – a few notes on pages 1 to 8

Alec Rawls has taken the brave step of releasing the first order draft of the UNIPCC AR5 Report. Anthony Watts has republished at Wattsupwiththat.

Although Alec Rawls published in breach of signed undertakings, I comment and quote the report in the public interest. There is more than a single, unequivocal, interpretation of the data. To claim otherwise is dogma. This dogma is being used to justify policies that promote net harm to western economies, particularly the poorer and more vulnerable sections of society. In the name of this dogma, impartiality is being annulled and dissenters called nutters.

I have started with some initial observations on the first eight pages on the Summary for Policymakers – the only bit that people ever read. Like utterings from the Kremlin on the 1970s and 1980s, the coded language says as much or more than the actual words.

Major points

  1. No admission of lack of recent rise in the surface temperature record.
  2. But the lack of recent rise is accounted for by a step change in the warming in the Southern Oceans.
  3. AR4 got it wrong on decreasing precipitation in the tropics (which underlay Africagate), and they got it wrong on increasing hurricanes.
  4. Sea level rise is not accelerating. In fact the recent rise since 1993 is similar to the 1930-1950 period.
  5. Global glacier melt is not accelerating. Himalayas do not even get a mention.
  6. Medieval Warm Period gains more recognition than the AR4. However, recent studies will render AR5 out of date before it even published.

Page 3 Lines 21-25.
On temperatures there is a cover-up of the recent lack of warming. They cannot admit that global average temperatures have not changed for 15 years.

Page 3 Lines 38-40. Precipitation in the tropics likely increased over the last decade, reversing a previous trend from mid-70s to mid-90s. The AR4 prediction of some African countries experiencing up to a 50% reduction in crop yields by 2020 (Africagate) was based upon a belief increasing extreme drought.

Page 3 Lines 46-48

Changes in many extreme weather and climate events have been observed, but the level of confidence in these changes varies widely depending on type of extreme and regions considered. Overall the most robust global changes are seen in measures of temperature {FAQ 2.2, 2.6} (see Table SPM.1).

Translation – Saying that an extreme weather events are evidence of global warming has no scientific validity. Best measures are of global temperature, which we can’t admit have been failing to rise.

Page 4 Line 14. An admission that previous IPCC reports got it wrong on tropical cyclones getting more extreme.

Page 4. Lot of stuff on Trenberth’s missing heat being in the oceans. Oceans have been warming since 1971. The lack of warming of air temperatures since the mid-90s could be accounted for by this comment on lines 36-37

It is very likely that the Southern Ocean has warmed throughout the full ocean depth since the 1990s, at a rate of about 0.03°C per decade.

The lack temperature rise is explained by the heating up of the oceans. Global warming is now confined to the Southern Ocean. It is imperceptible, so on the Southern perimeter it is not sufficient to have stopped the increase in Antarctic sea ice from extending slightly.

Then this

Warming of the ocean accounts for more than 90% of the extra energy stored by the Earth between 1971 and 2010. Upper ocean (0–700 m) heat content very likely increased at a rate between 74 [43 to 105] × 1012 W and 137 [120 to 154] × 1012 W for the relatively well-sampled 40 year period from 1971 to 2010. Warming has also been observed globally below 4000 m and below 1000 m in the Southern Ocean, in spite of sparse sampling (see Figure SPM.1). {3.2, Box 3.1, Figure 3.2, Figure 3.3}

The very likely heating of the Southern Ocean, is based on sparse sampling?

Page 4. Line 46. Seas have very likely become saltier. That is has become less alkaline. On Page 6 lines 30-31, Ph decline is 0.015 to 0.024 per decade over last 3 decades. Call becoming less alkaline “acidification”, which is inaccurate. Oceans are heading towards Ph neutrality.

Page 5. Glaciers are globally still shrinking. No mention of Himalayas, and no mention of global acceleration. Range is “210 [145 to 275] Gt yr–1 to 371 [321 to 421] Gt yr–1“. Omit to convert these to sea level rise. 210 Gt = 0.64mm. 421 Gt = 1.29mm (Oceans = 326.2m km2 & 1 Gt water = 1 km3). In old money, glaciers are contributing 2.5 to 5.1 inches per century.

Page 5 Lines 47-49. Sea levels

It is virtually certain that over the 20th century the mean rate of increase was between 1.4 to 2.0 mm yr-1, and between 2.7 and 3.7 mm yr-1 since 1993. It is likely that rates of increase were similar to the latter between 1930 and 1950.

Translation. Sea levels are rising but not accelerating. If sea levels are a lagged response to rising surface temperatures, then (using the HADCRUT3 surface temperature data) we would expect the rise in sea levels to level off in the next few years, unless there is continued warming in the oceans.

Pages 6 to 7 Long-Term Perspective from Paleoclimatic Records

There was a medieval warm period, despite what Micheal Mann and others said in 1998 and 1999. But the MWP is less than the temperatures at the end of the twentieth century. However, due to time schedules for acceptance into AR5, they ignore Christiansen and Ljungqvist April 2012 and Ljungqvist et al 2012. The later, despite including discredited proxies such as Briffa’s notorious Yamal data, quite clearly shows rom 120 proxies that the 10th century had higher temperatures than at the end of the 20th century.

Similarly the Esper et. al 2012 of summer temperatures in Northern Scandinavia will render this part of the report out-of-date prior to it being published.

In 2006 the UNIPCC could bring themselves to bend the rules to allow in a corrupt scientific paper that suited their purposes, but this time they ignore two strong cases that undermine their case. If there is an AR6 around 2020, the UNIPCC will have to face the scientific evidence.

Page 8 The last IPCC report overestimated the impact of aerosols. The net impact of greenhouse gases and aerosols rises from 1.72 W m-2 to 2.40 W m-2. Negative forcings dramatically fall. The positive forcing impact falls, despite the major contributor, CO2 rising from 1.66 W m-2 to 1.82 W m-2. The net impact of CO2 reduces from 100% to around 75% of warming impact. It is no longer possible to talk of “rising CO2″ as a shorthand for anthropogenically-caused rising greenhouse gases.
