AGW Theory - Discussion

Years of false predictions, decades really, and yet the alarmists still tout the "science" card like they've predicted everything correct all along.

Makes me laugh.

Some predictions are made, sometimes they are close, other times they are off. If you know there's a 50/50 chance of flipping a coin and getting heads, that doesn't mean that getting 3 or 4 in a row invalidates that 50/50 chance.

Can you point to one study over the past 30 years that's gotten today's temp right?

Can you point to 10?

The extra snowfall that began 10,000 years ago has been slowly accumulating on the ice sheet and compacting into solid ice over millennia, thickening the ice in East Antarctica and the interior of West Antarctica by an average of 0.7 inches (1.7 centimeters) per year.

But it might only take a few decades for Antarctica’s growth to reverse, according to Zwally. “If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same rate they’ve been increasing for the last two decades, the losses will catch up with the long-term gain in East Antarctica in 20 or 30 years -- I don’t think there will be enough snowfall increase to offset these losses.”

“The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away,” Zwally said. “But this is also bad news. If the 0.27 millimeters per year of sea level rise attributed to Antarctica in the IPCC report is not really coming from Antarctica, there must be some other contribution to sea level rise that is not accounted for.”

To get away from the slapfight for a moment, I'm interested in hearing speculation on where this extra water is coming from.

The dude from NASA didn't say anything, so they're likely not in a position to say anything concrete. If I had to venture a wild guess, I'd say melting land ice and permafrost from arctic locations like Alaska, Russia, Greenland, and Canada.

Hmm, not gonna say anything concrete huh? Sounds like they're..... skeptical.

It's also outside the scope of the study so they shouldn't be expected to offer anything concrete. It's a topic for future research.

Whoops looks like Antarctica isn't really loosing ice at all and gaining it instead.

Just chalk it up on that long list of doomsday predictions that aren't coming true.

Remember when alarmists screamed that loss of ice was proof positive that panic was justified? Good times.....

"Antarctica is loosing ice" has been a staple of the AGW crowd for at least 10 years. Now we find out that whoops it's actually been gaining ice.

The alarmists were flat out wrong. Again.

Why is plotting the average of 102 models valid as an comparison?

Relentless emissions of heat-trapping gases are endangering the planet, the World Meteorological Organization says

GENEVA, Nov 9 (Reuters) - Greenhouse gas levels in the atmosphere reached a record high in 2014 and the relentless fuelling of climate change is endangering the planet for future generations, the World Meteorological Organization said on Monday.

"Every year we say that time is running out. We have to act NOW to slash greenhouse gas emissions if we are to have a chance to keep the increase in temperatures to manageable levels," WMO Secretary-General Michel Jarraud said in a statement.

His annual plea for the world to do whatever it can to cut greenhouse gas emissions - which come mainly from burning fossil fuels and from agriculture, cement production and deforestation - comes weeks before negotiators from over 190 states convene in Paris to try to agree a new U.N. climate deal.

Graphs issued by the WMO, a U.N. agency, showed levels of carbon dioxide, the main greenhouse gas, climbing steadily towards the 400-parts-per-million (ppm) level, having hit a new record every year since reliable records began in 1984.

Carbon dioxide levels averaged 397.7 ppm in 2014 but briefly breached the 400-ppm threshold in the northern hemisphere in early 2014, and again globally in early 2015.

"Next year we will be reporting much higher concentrations because of El Nino," WMO atmospheric research chief Oksana Tarasova told Reuters, referring to the Pacific Ocean warming phenomenon.

Soon 400 ppm will be a permanent reality, Jarraud said.

"It means hotter global temperatures, more extreme weather events like heat waves and floods, melting ice, rising sea levels and increased acidity of the oceans. This is happening now and we are moving into uncharted territory at a frightening speed."

The rise in carbon dioxide levels is being amplified by higher levels of water vapour, which are in turn rising because of carbon dioxide emissions, the WMO said.

Levels of the other two major man-made greenhouse gases, methane and nitrous oxide, also continued a unrelenting annual rise in 2014, reaching 1,833 parts per billion (ppb) and 327.1 ppb, respectively. Both rose at the fastest rate for a decade.

For the Paris conference later this month, more than 150 countries, led by top greenhouse gas emitters China and the United States, have issued plans to limit emissions beyond 2020.

But the plans revealed so far will not curb emissions enough to meet a target agreed in 2010 to limit global warming to within 2 degrees Celsius (3.6 Fahrenheit) of pre-industrial levels.

"Two degrees will be bad enough but it will be better than three degrees," said Jarraud. "Of course it would have been better to have 1 degree... But 1 degree is not possible any longer. It's just not feasible. Too late." (Reporting by Tom Miles; Editing by Mark Heinrich)

Some good news on the global warming front for a change.
