Explain the nonsence in the rationale. There is science and and surely observations. Its a discussion part of ASF.
These are the sorts of comments that are gradually turning people away from this site.

Disagreeing with your non scientific opinion is turning people away from this site?
Good Lord Plod! That's even more ridiculous than your previous post.

Nope. But saying that all the recognised climate scientists are creating false stories about the changes in our climate and the reasons for them does tend to turn off people who respect reality.

Well you do have an interesting take on reality bas.
A reality of alarmist modelling which has consistently failed to materialise.
A reality which is unfailingly mendacious in representing the views of moderates.
Unreal mate, unreal.

And denial like that in the face of a world with repeated record temperatures and evidence of rapid climate change around the globe is one of the basic reasons we are facing a crisis.

And its emerging that the mean temperature of the ocean that scientists had been modelling from is now being proved as eight degress cooler than previously known.
Under/over statments to keep the mulititides content has been the order. However the tide in community awareness is the big one coming to surface.
And I gave the reference a week back but its common knowledge to those paying attention.

This is the latest article which pulls together what is happening with CC and the current and future consequences.
Not pretty but real.

The United States Global Change Research Program recently released a report on the science of climate change and its causes. The report is available for anyone to read; it was prepared by top scientists, and it gives an overview of the most up to date science.
If you want to understand climate change and a single document that summarizes what we know, this is your chance. This report is complete, readily understandable, and accessible. It discusses what we know, how we know it, how confident we are, and how likely certain events are to happen if we continue on our business-as-usual path.
To summarize, our Earth has warmed nearly 2°F (1°C) since the beginning of the 20th century. Today’s Earth is the warmest it has ever been in the history of modern civilization.

While the planet has warmed, the climate and the Earth’s environment has responded. We are observing heating of the atmosphere, oceans, and the Earth’s surface. Glaciers are melting at an alarming rate. Snow cover is decreasing and we are experiencing increased water scarcity, particularly in parts of the world that rely on snowmelt for water.
The amount of ice is decreasing. In particular, the ice that floats atop waters in the Arctic have decreased significantly since measurements began. As a result of melting land ice and thermal expansion, sea levels are rising. Oceans have risen, on average, 7–8 inches. In some places, the rise has been much more. Astonishingly, half of the total rise has occurred in the last 30 years. Currently, oceans are rising faster than any point in time in the last ~3,000 years. Not only that, the ocean rise is causing city flooding to accelerate.
According to the report, seal levels will likely rise somewhere between 1–4 feet by the end of the century, but increases up to 8 feet can’t be ruled out (~2.5 meters). For context, approximately 150 million people around the world live within one meter of current sea level.
If you live away from the shores, you are not immune to the impacts of climate change. The report delves into the increases in extreme weather. For instance, heavy rainfall is increasing across the United States as well as globally. These increases will continue into the future and they are already leading to more severe flooding. The prediction that scientists made that wet areas will become wetter is turning out to be true.
There are more extreme heatwaves as well. Not only are we seeing more heat waves (and severe droughts), but in the next few decades, the authors predict temperatures will rise by ~2.5°F (~1.5°C) in the United States. This is an enormous change in temperature that will reshape the country. Similar changes are occurring and will occur in other countries.
What the report also shows is that the biggest uncertainty in future climate change is us. What will humans do about it? We have the choice of taking action now to reduce future climate change. Or, we can ignore the problem and face the consequences. That choice has tremendous implications. If we take strong actions to reduce greenhouse gases, we may be able to limit global warming by 2100 to 3.5°F (2°C) above pre-industrial temperatures. If we ignore the problem, we will face temperature increases as much as 9°F (5°C). The impact such a temperature change would have on agriculture, sea level, heat waves, droughts, and weather is almost unthinkable.
There is some hope in this report. Even with recent economic growth, the rate at which we emit greenhouse gases has not risen as fast as the past. This means it is possible to have a healthy economy and a healthy environment.
For those who say dealing with climate change is too expensive, they repeat a myth. In fact, ignoring climate change is much more expensive then dealing with it. Had we taken action years ago when scientists first warned us of the problem we would be well on our way to effective mitigation. We’ve lost valuable years to the denialists. The more time we waste, the more expensive this problem will be in both lives and dollars.

Dealing with Global Warming and the destruction of Coral reefs
Perhaps there is a chance to intervene and save our coral reefs to a certain point. Would be a good sign.
New lab-bred super corals could help avert global reef wipeout
Pioneering research on cross-species coral hybrids, inoculations with protective bacteria and even genetic engineering could provide a lifeline for the ‘rainforests of the oceans’
New super corals bred by scientists to resist global warming could be tested on the Great Barrier Reef within a year as part of a global research effort to accelerate evolution and save the “rainforests of the seas” from extinction.
Researchers are getting promising early results from cross-breeding different species of reef-building corals, rapidly developing new strains of the symbiotic algae that corals rely on and testing inoculations of protective bacteria. They are also mapping out the genomes of the algae to assess the potential for genetic engineering.
Innovation is also moving fast in the techniques need to create new corals and successfully deploy them on reefs. One breakthrough is the reproduction of the entire complex life cycle of spawning corals in a London aquarium, which is now being scaled up in Florida and could see corals planted off that coast by 2019.
“It is a story of hope, rather than saying ‘it’s all going to die and there’s nothing we can do about it’,” said Prof Madeleine van Oppen, from the Australian Institute of Marine Science and the University of Melbourne.
The researchers, who presented their cutting-edge work at a conference at the University of Oxford last week, acknowledge that such serious biological interventions on coral reefs could be seen as controversial or risky.
“But it is too late to leave them alone, given the pace at which we are losing corals,” said van Oppen, who said the broad aim is to speed up natural evolutionary processes. “I don’t have any problem with that. We have already intervened in the marine environment tremendously and there is no part where we cannot see human influence.”
Coral reefs are critical ecosystems in the oceans, hosting more than a million species and sustaining natural services worth $10tn a year, including providing vital food for 500 million people. But climate change is heating the oceans and causing corals to bleach: reefs could die out as early as 2050, with perhaps half already gone.

Yep Merridy exmas. As a shearer in the 1960's myself can relate to this bloke:
"Not long after leaving school, I followed the well-trodden path of many farm girls and boys; packing my bags and joining a shearing team. Through 40-plus degree days of skirting fleeces and grinding blades (hot tip, this is not a good way to cool down) on the edge of the pastoral country during a Western Australian summer as a 17-year-old, I had no idea the suffocating heat was rapidly becoming a defining feature of our changing climate. Fast forward more than a decade and as I write this, in Crookwell, NSW it’s 38 degrees and a local sheep farmer has come in from an early morning start – forced to muster his lambs before the inescapable heat stresses livestock, and farmers. Shaking his head as the sweat drips down, he wonders how to adjust to temperatures 14 degrees above average.
For most urban dwellers, summer means time by the pool and flocking to the nearest shopping centre when the heat becomes too much. For Australian farmers, summer means something very different.
A heatwave means never-ending water runs, relishing the chance to clean out troughs in the hope that wet jeans will keep you cool for at least a few minutes.
It’s the sight of working dogs collapsed in the shade of the field bin – seeking just a short reprieve from the inescapable heat. It’s the constant fear of header fires; when everything is bone-dry and the slightest spark from overheated machinery can create a raging inferno; endangering lives and wiping out crops, pastures and infrastructure.
According to CSIRO and BOM data from 1950-2013, heatwaves are more frequent over much of Australia. The first heatwave of each season is occurring earlier, virtually everywhere, and the hottest days of heatwaves are becoming even hotter. Like most farmers, I’m a big fan of our sunburnt country, our land of drought and flooding rains. What I’m less fond of is the flow-on impacts of the increased number and intensity of heatwaves which are rapidly becoming a defining feature of climate change. Fruit, vegetables, grains, and grapes all struggle to cope under hot conditions. Fruit wilts in the paddock and grapes ferment before your eyes; tempers fray as the stress of maintaining farm productivity under unprecedented conditions takes its toll.
For livestock producers, the burden is immense with heatwaves dramatically impacting on the well-being and productivity of beef and dairy cattle, with many struggling to ever return to pre-heatwave productivity levels. Sheep farmers are no better off, with studies demonstrating a drop in ram fertility as a result of heatwave conditions.
What does this mean for productivity on farm, and what can our farmers do to adjust? Many are already leading the way by integrating sprinkler systems into feedlots, going off the grid to ensure reliable energy supplies as our coal-fired power stations melt down in the heat – a heat which they’ve helped to perpetuate. Others are turning to vegetation and even shade cloth for some degree of protection. Meanwhile, our scientists work against time to expand the reach of heat and drought-tolerant crop varieties.
While farmers are sweltering in the paddocks and crops are literally sizzling on the stalks, our federal government has comprehensively failed to develop a credible and cohesive climate and energy policy framework to alter Australia’s climate trajectory. In the air-conditioned halls of Parliament, our leaders are cushioned from the realities of climate change. Our farmers are not."

The oceans are suffocating. If they go, we go.
Oceans suffocating as huge dead zones quadruple since 1950, scientists warn
Areas starved of oxygen in open ocean and by coasts have soared in recent decades, risking dire consequences for marine life and humanity

Ocean dead zones with zero oxygen have quadrupled in size since 1950, scientists have warned, while the number of very low oxygen sites near coasts have multiplied tenfold. Most sea creatures cannot survive in these zones and current trends would lead to mass extinction in the long run, risking dire consequences for the hundreds of millions of people who depend on the sea.
Climate change caused by fossil fuel burning is the cause of the large-scale deoxygenation, as warmer waters hold less oxygen. The coastal dead zones result from fertiliser and sewage running off the land and into the seas.
The analysis, published in the journal Science, is the first comprehensive analysis of the areas and states: “Major extinction events in Earth’s history have been associated with warm climates and oxygen-deficient oceans.” Denise Breitburg, at the Smithsonian Environmental Research Center in the US and who led the analysis, said: “Under the current trajectory that is where we would be headed. But the consequences to humans of staying on that trajectory are so dire that it is hard to imagine we would go quite that far down that path.”
“This is a problem we can solve,” Breitburg said. “Halting climate change requires a global effort, but even local actions can help with nutrient-driven oxygen decline.” She pointed to recoveries in Chesapeake Bay in the US and the Thames river in the UK, where better farm and sewage practices led to dead zones disappearing.
However, Prof Robert Diaz at the Virginia Institute of Marine Science, who reviewed the new study, said: “Right now, the increasing expansion of coastal dead zones and decline in open ocean oxygen are not priority problems for governments around the world. Unfortunately, it will take severe and persistent mortality of fisheries for the seriousness of low oxygen to be realised.”

The analysis, published in the journal Science, is the first comprehensive analysis of the areas and states: “Major extinction events in Earth’s history have been associated with warm climates and oxygen-deficient oceans.” Denise Breitburg, at the Smithsonian Environmental Research Center in the US and who led the analysis, said: “Under the current trajectory that is where we would be headed. But the consequences to humans of staying on that trajectory are so dire that it is hard to imagine we would go quite that far down that path.”
“This is a problem we can solve,” Breitburg said. “Halting climate change requires a global effort, but even local actions can help with nutrient-driven oxygen decline.” She pointed to recoveries in Chesapeake Bay in the US and the Thames river in the UK, where better farm and sewage practices led to dead zones disappearing.
However, Prof Robert Diaz at the Virginia Institute of Marine Science, who reviewed the new study, said: “Right now, the increasing expansion of coastal dead zones and decline in open ocean oxygen are not priority problems for governments around the world. Unfortunately, it will take severe and persistent mortality of fisheries for the seriousness of low oxygen to be realised.”

2017 was the hottest year on record without an El Niño, thanks to global warming
Climate scientists predicted the rapid rise in global surface temperatures that we’re now seeing

2017 was the second-hottest year on record according to Nasa data, and was the hottest year without the short-term warming influence of an El Niño event:

1964–2017 global surface temperature data from Nasa, divided into El Niño (red), La Niña (blue), and neutral (black) years, with linear trends added.
In fact, 2017 was the hottest year without an El Niño by a wide margin – a whopping 0.17°C hotter than 2014, which previously held that record. Remarkably, 2017 was also hotter than 2015, which at the time was by far the hottest year on record thanks in part to a strong El Niño event that year.
For comparison, the neutral El Niño conditions and the level of solar activity in 1972 were quite similar to those in 2017. 45 years later, the latter was 0.9°C hotter than the former. For each type of year – La Niña, El Niño, and neutral – the global surface warming trend between 1964 and 2017 is 0.17–0.18°C per decade, which is consistent with climate model predictions.

This thread is a vestigial indulgence for the few remaining warmist zealots. Incited by their political commissars, whilst it is convenient for the background Leftist narrative.
Australians aren't silly. They will examine their electricity bills. Especially in South Australia, which now has the most expensive electricity in the world.
As for the Aus BoM, caught out falsifying the minimum temperature readings for Goulburn and Canberra. They are part of the problem. Minimal credibility.

2017 Was the Third Hottest Year on Record for the U.S.
Only 2012 and 2016 were warmer than last year

Last year was the third hottest on record in the United States, with an average temperature of 54.6 degrees Fahrenheit—2.6 F above average.
Only 2012 and 2016 were warmer than 2017, according a new report from NOAA. The five hottest years on record in the country have been in the last decade, based on 123 years of record-keeping.
The record heat means that every year since 1997 has been warmer than average in the United States. And in 2017, every state had a warmer-than-average year, and 32 recorded one of their 10 hottest years on record, according to NOAA.
"In 2017, every state in the Lower 48 had an average temperature that was above average, and this is the third consecutive year that has been the case," said Jake Crouch, a climate scientist at NOAA's National Centers for Environmental Information. "It's a continuation of what we saw in 2016, what we saw in 2015, and we also saw a continuation in 2012, so the warmth in 2017 really was observed coast to coast."
Five states—Arizona, Georgia, New Mexico, North Carolina and South Carolina—had their warmest years on record, according to NOAA. Alaska had its warmest December ever, 15.7 F above the average, for a statewide average of 19.4 F.
After two-thirds of the contiguous United States experienced a blast of Arctic air and low temperatures in the single digits in December, President Trump tweeted that more global warming might help make the weather less cold.
"Perhaps we could use a little bit of that good old Global Warming that our Country, but not other countries, was going to pay TRILLIONS OF DOLLARS to protect against," he wrote, in reference to the Paris climate agreement.
Scientists have long explained that winter and record cold snaps will not disappear as a result of climate change, and that cold spikes may get worse as a result of shifting weather patterns under global warming.
"We do live in a warming world, but we do have very cold poles, and we still have the weather systems that pull cold air away from those poles into areas where we live," said Deke Arndt, chief of climate monitoring at NOAA's National Centers for Environmental Information.
NOAA and NASA will release their global temperature report next week. Based on data recorded this year, they will likely announce that 2017 is the second- or third-warmest year on record.

And the deniers will just turn up the air con another notch and pretend everything is ok.
