i wonder how normal people dealt with morons before "ignore" was an option ???
you'll never know.
by 'ignoring' others you cannot understand you isolate yourself.
try removing yourself from the tapestry you've wrapped yourself in.

Planet has only until 2030 to stem catastrophic climate change, experts warn

(CNN)Governments around the world must take "rapid, far-reaching and unprecedented changes in all aspects of society" to avoid disastrous levels of global warming, says a stark new report from the global scientific authority on climate change.
The report issued Monday by the UN Intergovernmental Panel on Climate Change (IPCC), says the planet will reach the crucial threshold of 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels by as early as 2030, precipitating the risk of extreme drought, wildfires, floods and food shortages for hundreds of millions of people.
The date, which falls well within the lifetime of many people alive today, is based on current levels of greenhouse gas emissions.
The planet is already two-thirds of the way there, with global temperatures having warmed about 1 degree C. Avoiding going even higher will require significant action in the next few years.
"This is concerning because we know there are so many more problems if we exceed 1.5 degrees C global warming, including more heatwaves and hot summers, greater sea level rise, and, for many parts of the world, worse droughts and rainfall extremes," Andrew King, a lecturer in climate science at the University of Melbourne, said in a statement.
Global net emissions of carbon dioxide would need to fall by 45% from 2010 levels by 2030 and reach "net zero" around 2050 in order to keep the warming around 1.5 degrees C.
Lowering emissions to this degree, while technically possible, would require widespread changes in energy, industry, buildings, transportation and cities, the report says.
"The window on keeping global warming below 1.5 degrees C is closing rapidly and the current emissions pledges made by signatories to the Paris Agreement do not add up to us achieving that goal," added King.
Consequences of past inaction
The report makes it clear that climate change is already happening -- and what comes next could be even worse, unless urgent international political action is taken.
"One of the key messages that comes out very strongly from this report is that we are already seeing the consequences of 1 degree C of global warming through more extreme weather, rising sea levels and diminishing Arctic sea ice, among other changes," said Panmao Zhai, co-chair of IPCC Working Group I.
Even if warming is kept at or just below 1.5 degrees C, the impacts will be widespread and significant.
Temperatures during summer heatwaves, such as those just experienced across Europe this summer, can be expected to increase by 3 degrees C says the report.
More frequent or intense droughts, such as the one that nearly ran the taps dry in Cape Town, South Africa, as well as more frequent extreme rainfall events such as hurricanes Harvey and Florence in the United States, are also pointed to as expectations as we reach the warming threshold.
Coral reefs will also be drastically effected, with between 70 and 90% expected to die off, including Australia's Great Barrier Reef.
Countries in the southern hemisphere will be among the worse off, the report said, "projected to experience the largest impacts on economic growth due to climate change should global warming increase."
The report underlines how even the smallest increase in the base target would worsen the impact of recent natural disasters.
"Every extra bit of warming matters, especially since warming of 1.5 degrees C or higher increases the risk associated with long-lasting or irreversible changes, such as the loss of some ecosystems," said Hans-Otto Pörtner, Co-Chair of IPCC Working Group II.
The report cites specific examples of how impacts of global warming would be lessened with the 1.5 degrees C increase, compared to the 2 degrees C increase:
- Global sea levels would rise 10 cm lower by 2100.
- The likelihood of an Arctic Ocean free of sea ice in summer would be once per century, instead of at least once per decade.
- Coral reefs would decline by 70% to 90% instead of being almost completely wiped out.
Special Report: What it's like at the ground zero of climate change
View ImageThis chart from the IPCC shows how global temperatures would respond to a sudden and drastic reduction of greenhouse gas emissions. Even with immediate action, global temps will still overshoot the goal, but could reduce back to the target over time.
'Possible with the laws of chemistry and physics'
Monday's report is three years in the making and is a direct result of the 2015 Paris Climate Agreement. In the Paris accord, 197 countries agreed to the goal of holding global temperatures "well below" 2 degrees C above pre-industrial levels and to pursue efforts to limit it to 1.5 degrees C.
The United States was initially in the agreement, but President Donald Trump pulled the country out a year and half later, claiming it was unfair to the country.
To limit global warming to 1.5 degree C is "possible within the laws of chemistry and physics," said Jim Skea, co-chair of IPCC Working Group III. "But doing so would require unprecedented changes."
"International cooperation is absolutely imperative to limit emissions and therefore global warming and its impacts, as well as coordinating effective and widespread adaptation and mitigation," said Sarah Perkins-Kirkpatrick, a fellow at the Climate Change Research Center at the University of New South Wales. "The next few years will be critical in the evolution of these efforts."
One key issue will be negative emissions, large scale carbon-scrubbing technologies that can reduce the amount in the atmosphere and act to counter continued pollution.
According to the report, there are two main ways of removing carbon from the atmosphere: increasing natural processes that already do this, and experimental carbon storage or removal technologies.
However, all methods "are at different stages of development and some are more conceptual than others, as they have not been tested at scale," the report warned.
They will also require considerable political engagement globally, as will reducing the amount of carbon being emitted. Despite the report's dire warnings, there is no indication such cooperation will be doable, particularly given the Trump administration's stance on this issue.
"Today the world's leading scientific experts collectively reinforced what mother nature has made clear -- that we need to undergo an urgent and rapid transformation to a global clean energy economy," former US Vice President Al Gore said.
"Unfortunately, the Trump administration has become a rogue outlier in its shortsighted attempt to prop up the dirty fossil fuel industries of the past. The administration is in direct conflict with American businesses, states, cities and citizens leading the transformation."
Yes, it certainly cleans up the thread a lot when you can get rid of the irrational nonsense.
I did ONE single search for ''Optimum define.''

I think Yamaha has created an imaginary friend just to give himself some support in this thread.

You are right especially when it comes to viewpoints that disagree with yours. It's a huge problem right now people on the left and the right are not communicating or respecting one another. This is dangerous because it de-humanizes people with ideas that are different then your own.
However on the internet people abuse their free speech with spam. They steal time by repeating themselves over and over and this destroys any meaningful exchange of ideas. Spam is a form of censorship and that is what has happened in this thread. Someone plugging their ears and saying the same thing over and over disrespects the reader and the person trying to discuss the topic at hand.
Aside from a moderator cleaning this garbage up the ignore button is heaven sent. In this thread particularly because it's impossible to read posts by other members when one person creates pages and pages of spammy shit that must be crawled through to discuss the topic with others.
I almost lost your earlier post in the barrage of gibberish but I was able to read it because of ignore.
For days he's been in here squealing that ''Optimum" doesn't refer to the best biological conditions possible.
I've let it go on for days, because I knew what it meant, and why the term was invented: to describe the very best biological conditions
possible, and that in fact the word was first coined in English, in relation to these warm periods.
And that his insane shrieking of course was going to splatter like a bird hitting a brick wall the first tim I simply typed ''Optimum define.''
I did ONE single search for ''Optimum define.''
He's been in here squealing and swearing for days. Cursing and squealing like some sort of insane person, for days: about something that all he had to do was type the word one time.
Instead he's postured and contorted and slobbered and screamed, all to find out he couldn't have been more wrong.
The word was I.N.V.E.N.T.E.D. as DEFINITION for the VERY BEST BIOLOGICAL CONDITIONS POSSIBLE: For PLANTS and ANIMALS.

The crazy part is that we didn't know this stuff existed until 25 years ago but our lives depend on it. We think we are the focus of life, everything revolves around humanity and what it does. When there is so much we don't know or understand that is essential for our survival.
