Climate Change

Claim: Climate change now responsible for planes battling stronger winds

You can add this claim to the list of things now affected by Climate Change.

Passengers can expect longer flight times between Europe and America because of the effects of climate change, a new study has found.

Led by Dr Paul Williams, an atmospheric scientist at the University of Reading, the study found aircraft would spend an extra 2000 hours in the air every year as a result of global warming’s effect on the North Atlantic winter jet stream.

Jet streams are fast-flowing air currents within the upper atmosphere that typically flow from west to east, reducing flight time when a plane enters them.

Climate change would accelerate these jet streams, speeding up eastbound flights – but significantly slowing down flights in the other direction.   Read more »

Awesome news. Can we just cancel it now?

The Green taliban are outraged, because they say the Emissions Trading Scheme is so weak now it is ineffective.

An evaluation of the Emissions Trading Scheme shows the Government has “weakened the scheme to the point of ineffectiveness,” says Green Party co-leader James Shaw.

The Government released three technical reports last week, to help New Zealanders engage with a public review of the ETS.

One of those, a Ministry of Environment report into the performance of the ETS, found it provided businesses nearly no incentive to look at how to reduce their emissions.

Shaw said that with expenditure of $40m on setting up the ETS, and despite it being the Government’s main policy for tackling climate change, it was failing.    Read more »

Oh Look, NIWA doesn’t blame global warming for once

Wonders will never cease.

NIWA hasn’t even mentioned global warming or climate change in their release about January temperatures.

Auckland has recorded its warmest January in 70 years, with residents sweltering in unrelenting humid weather.

Warm, humid tropical air flows caused record mean January temperatures in four centres, the National Institute of Water and Atmospheric Research says.

Auckland recorded a mean air temperature of 20.5degC, its highest since 1945.    Read more »

Killing truth by degrees

The last two days in Auckland have been very warm days. There were a few wisecracks around it being global warming. The ‘official’ temperature in Auckland was around 29 degrees. But hang on a minute. It was 31° in Botany and only 28° in Piha. So is 29° an average? No, there is only one recording place. So there were large areas of Auckland that were not 29°. Could 29° be categorised as ‘an average’ for Auckland? We could try but it would not be accurate. We don’t know which areas were 31° and which were 29°. We don’t know how big those areas were. Some places may have been 27°. Some temperatures were recorded at midday others at 3.00pm. Recording temperature is problematic, nigh impossible.

OK, so what if we take one spot and record the temperature every day at exactly the same time wouldn’t that give us a pattern over time?  Yes, but what pattern? Take Botany. Fifty years ago it was open fields. Now it’s all tin roofs, tarseal and concrete. That would distort the pattern.

So let’s take Botany out and use the other recordings around Auckland. Piha might work but Auckland City is also distorted by growing urbanisation. For historical accuracy, using temperature recordings in Auckland is well-nigh useless.

Who cares? Who can ‘feel’ a one-degree change in temperature anyway? Not too many people I guess but a degree difference in global warming land is massive. In the rarefied atmosphere of global warming a tenth of a degree is hugely statistically significant.

Over the last month the climate change enthusiasts have been crowing about 2015 being the hottest year on record. It broke the record by 0.02° F. Wow! One fifth of one tenth of one degree. Did you feel that? Take your shirt off?   Read more »

The madness post-Paris and COP21

Someone has calculated the new power generation required when coal-fired power is turned off and gas to houses is stopped – the numbers are mind boggling.

To meet the COP 21 rules Britain will need 1.5 million more wind turbines or 750 new DRAX sized thermal power stations burning 5 billion tonnes of wood pellets imported from the US.

You can’t make this stuff up.

Plus every street has to be dug up to add the cable to carry these loads…

COP21 Paris climate conference urged that all home heating should move away from gas to be all electric. In the UK the Climate Change Act already assumes this scenario will be put into practice.

Just how realistic is this for the UK?

There are around 16 million (16 × 106) households connected to the gas grid network in the UK.

The average household boiler is rated at 60 kiloWatt

To replace that with electric home heating would still require about the same electrical capacity. (Remember even a single electric shower is 7 kW, and an oven approaching 10 kW).2

Here’s the math(s):

16 × 106 × 60 kW = 96 × 107 =~ 100 × 107 = 109 kW = 106 MegaW = 103 GigaW

or about 1 TeraW of extra power.

Drax, in Yorkshire England (which was the UK’s biggest and most efficient coal fired power station), generates about 4 GW, therefore to generate this extra 1 TW we would need to build about 250 Drax sized power stations, or erect half a million 5 MW (in reality, 2 MW) wind turbines [for reference: current requirement in the UK is a mere 40 GW, that is 0.04 TW].

“Record-breaking” blizzard in USA in the “hottest year on record”

A winter storm has dumped nearly 58cm of snow on Washington DC and Baltimore, before moving on to Philadelphia and New York, paralysing road, rail and airline travel along the US east coast.

At least 10 states declared weather emergencies on Saturday (Sunday NZ Time), aiming to get a handle on highways made impassable by the drifting snow and to shore up coastal areas where the blizzard conditions raised the danger of flooding.

High winds battered the region, reaching 110km per hour in Wallops Island, Virginia, late on Friday (Saturday NZT), said meteorologist Greg Gallina of the National Weather Service.

Hang on, I thought we just ‘celebrated’ the warmest year on record?

Apparently global warming isn’t that bad. After all, if it was really real and as catastrophic as has been suggested, we wouldn’t be getting headlines about the pending snow-pocalypse about to descend on the US.

One in seven Americans will get at least half a foot of snow outside their homes when this weekend’s big storm has finished delivering blizzards, gale-force winds, whiteout conditions and flooding to much of the eastern United States.

The first flakes of what could become two feet or more of wet, driving snow began falling in Washington Friday afternoon, sloshing in from the Ohio River Valley looking just like the forecasts promised.   Read more »

Now hang on a minute, this doesn’t make sense

Apparently climate change is to blame for a lake in Bolivia drying up.

Or so a scientist says. What this is, in reality, is another manipulative alarmist article blaming something on climate change that is unsupported by the facts.

Overturned fishing skiffs lie abandoned on the shores of what was Bolivia’s second-largest lake. Beetles dine on bird carcasses and gulls fight for scraps under a glaring sun in what marshes remain.

Lake Poopo was officially declared evaporated last month. Hundreds, if not thousands, of people have lost their livelihoods and gone.

High on Bolivia’s semi-arid Andean plains at 3,700 metres (more than 12,000 feet) and long subject to climatic whims, the shallow saline lake has essentially dried up before only to rebound to twice the area of Los Angeles.

But recovery may no longer be possible, scientists say.

“This is a picture of the future of climate change,” says Dirk Hoffman, a German glaciologist who studies how rising temperatures from the burning of fossil fuels has accelerated glacial melting in Bolivia.

As Andean glaciers disappear so do the sources of Poopo’s water. But other factors are in play in the demise of Bolivia’s second-largest body of water behind Lake Titicaca.

NASA: “Impossible to deny climate change”; Nobody is denying it, we’re just not convinced it’s humans who are to blame

Nobody is denying it, we’re just not convinced it’s humans who are to blame.

It’s impossible to deny climate change following the record breaking temperatures last year, a scientist from the American space agency NASA says.

Compton Tucker told RNZ News there was every reason to believe that 2016 would break last year’s record.

“We’re starting to see the death of climate change denial, that is the evidence accumulated from multiple sources.

“The evidence is overwhelming and there are people who are wilfully ignorant about climate change and they invoke a wide variety of mechanisms which are pretty silly.”

New Zealand climate scientist James Renwick said countries needed to start getting on top of greenhouse gas emissions.

He said the global economy was built on fossil fuels and that couldn’t be changed overnight.

“There are very rapid changed changes in renewable technologies, electric vehicles and so on and that’s great, but to really change the direction of the global economy in terms of how energy’s produced is a big ask and it will take time. The thing is we really need to start.”

Dr Renwick said there had been talk about this problem for 25 years and nothing had happened – but he said wasn’t too late to turn things around.

He said New Zealand’s emissions profile was unusual, with almost half coming from the agricultural sector.

However, the biggest growth areas for emissions came from the transport and energy sectors.   Read more »
