Global Warming vs. Solar Cooling: The Showdown Begins in 2020

Global Warming vs. Solar Cooling: The Showdown Begins in 2020
The sun may be dimming, temporarily. Don't panic; Earth is not going to freeze over. But will the resulting cooling put a dent in the global warming trend?
A periodic solar event called a "grand minimum" could overtake the sun perhaps as soon as 2020 and lasting through 2070, resulting in diminished magnetism, infrequent sunspot production and less ultraviolet (UV) radiation reaching Earth — all bringing a cooler period to the planet that may span 50 years. |

The two authors cited by Tehchno work for the Heartland Institute, which is paid by the carbon companies to mis-represent the science of climate change. The comments about temperatures and their accuracy is the first obvious whopper in the story. In fact, temperature records are taken from a vast array of sources, and complex algorithms have been developed to make the data comparable. The denier business has been misrepresenting temperature data for more than a decade. Millions of dollars flow to Heartland to tell these lies. People with no interest in science, but deep suspicion, believe them. |
The exact definition of a closed mind. He will never consider anything opposing what he believes, regardless of the source. Slow down a bit, you are making too many typos (Tehchno), plus there is no hypen in misrepresent, which isn't a typo. |
I’m not going to let you go on this one Techno. You posted something from Heartland Institute staff, and when I said they were not credible and their argument was nonsense you said I had a closed mind. No, I know these guys as liars and whores for tobacco and carbon. Their argument in the article is untrue. If you had paid any attention to their credibility, and looked for the other side of the argument you could have discovered that. Your approach is exactly what I have described as the death of critical thinking. Or, in education, teaching to the test. They get paid $5 million a year to lie for big business, mostly big carbon, afer being caught lying for big tobacco.

Top US scientist Hal Lewis resigned from his post at the University of California after admitting that global warming was a big scam, in a shocking resignation letter.

Where does Malibu Barbie find this ancient fake "news"? The back of his Barbie closet? Wonder what else is in there? |

Bard’s troll sources got most of it wrong. Hal Lewis was a physicist at the University of California Santa Barbara (we are chauvinistic about recent upstarts like UCSB), who worked on nuclear defense. Few peer reviewed articles, none on climate. To be sure, he knew about global warming—but wasn’t sure about the magnitude or how much of it could be natural. Hardly earthshaking. Like dozens of claims by deniers that I have run down, the story is mostly spin, or sourced by a paid denier with no expertise. Interesting article here: https://dotearth.blogs.nytimes.com/2010/10/15/a-physicists-climate-complaints/
Of course this is a conservative media attempt to divert attention from first, the Mueller indictments (and Gates flipping) and second, Republican obstruction in the face of yet another school shooting. |

This is actually news, not 8 years old, and not trolled by deniers who make money from the delay.

The world is far off course from its goals in cutting greenhouse gas emissions — and research published Tuesday illustrates one of the most striking implications of this.
Namely, it finds that for every five years in the present that we continue to put off strong action on climate change, the ocean could rise an additional eight inches by the year 2300 — a dramatic illustration of just how much decisions in the present will affect distant future generations.
“One important point was to reveal that sea level [rise] is not in the far future, it’s now, and because the system is so slow, we just can’t see it at the moment,” said Matthias Mengel of Germany’s Potsdam Institute for Climate Impact Research, the lead author of the study, which was published in Nature Communications. “But we cause it now.”
The study, which also included scientists at institutions in Australia and Austria, takes as its premise that the world will work to achieve the Paris climate agreement’s sharp cuts in greenhouse gas emissions. The goal is to limit warming below 2 degrees Celsius (3.6 degrees Fahrenheit), which requires that the world essentially cease adding any more greenhouse gases to the atmosphere by 2050 or so.
This, in turn, means that global greenhouse gas emissions must reach a peak by either 2020, 2025 or 2030 (or possibly 2035) and then begin to decline rapidly. The longer the wait, the faster the necessary decline after the peak. If we delay longer still, it simply becomes too difficult to bring emissions down fast enough to avoid dangerous levels of global warming.
[The world’s efforts to slow climate change aren’t working]
All of this has major implications for the global sea-level-rise commitment, the study finds. Because emissions today impel rising seas over centuries, the researchers were able to calculate a surprisingly large impact of present choices on sea levels in the distant future.
For every five-year delay in the peaking of emissions, the middle-range sea level projection for 2300 increased by 20 centimeters, or about eight inches, the study found.
“The more cumulative emissions, the more warming, the more sea level,” Mengel explained.
And that’s just the central estimate in the study. At the extreme end of what’s relatively unlikely but still certainly possible, the research found that each five-year delay could mean as much as an additional meter, or over three feet, of sea level rise. That is because of the ever-growing chance of major destabilization of the Antarctic ice sheet. In some small number of scenarios, even with the sharp emissions reductions contemplated by the Paris agreement, the Antarctic ice sheet still gives up meters worth of sea level rise |
Note, scientists. But I guess end times and runaway inflation due to the Trump tax cuts for the rich will end the world before then. |
