Climate Concerns

The "CLIMATE CONCERNS" group is dedicated to discussion regarding the topic of the ever present and serious issue of changes to our climate due to the introduction into the atmosphere of human induced effects which prove harmful to the environment and which eventually may prove destructive to our planet.

Lake Erie Bloom 

Comment by Joan Denoo on September 27, 2017 at 3:53pm

Lake Erie Abloom

"On September 26, 2017, the Operational Land Imager (OLI) on the Landsat 8 satellite captured these natural-color images of a large phytoplankton bloom in western Lake Erie.

"According to the National Oceanic and Atmospheric Administration, the bloom contains microcystis, a type of freshwater cyanobacteria. These phytoplankton produce toxins that can contaminate drinking water and pose a risk to human and animal health (skin irritant, respiratory distress) when there is direct contact.

"A few days earlier, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured a wider view of the lake. Blooms tend to thrive in Lake Erie during summer, sustained by warm water temperatures and nutrients from farm runoff. This year, the bloom has been ongoing since mid-July.

Humans' Great Filter

“Peter Ward, a charismatic palaeontologist among those responsible for discovering that the planet's mass extinctions were caused by greenhouse gas, calls this the 'Great Filter': 'Civilizations rise, but there's an environmental filter that causes them to die off again and disappear fairly quickly,' he told me. 'If you look at planet Earth, the filtering we've had in the past has been in these mass extinctions.'

“The mass extinction we are now living through has only just begun; so much more dying is coming.”

Peter Douglas Ward, paleontologist and professor at the University of Washington, Seattle, and Sprigg Institute of Geobiology at the University of Adelaide.

"Scientists are currently debating whether we are now in the midst of the Earth's sixth mass-extinction event or approaching it. Either way, the situation is dire — the existential risks posed by a worst-case climate-change scenario are real.

"If those risks become serious enough to act as humans' Great Filter, it may be too late for us to communicate with anyone else in our universe."

Thanks for the refusing to stand for the national anthem link, Joan. About our 30 year existential threat, it's funny how class, race, and gender injustice issues have become inextricably entangled with climate concerns. I don't see us coming out of this Great Filter climate destabilization situation without embracing equality. 

Sometimes I imagine that if scientific models predicted existential threat next month, 95% wouldn't give it enough credence to embrace more than comfortable incremental change. Certainly not solutions that include class, race, and gender equality.

As Ken Ward put it,

At a moment when we should be striding forward with the strength of prophets proved right, we wander ... without effective plan, purpose or voice.

Tragically, those who have been concerned (but not too concerned) about climate change demanded this arrangement, voting for chipper milquetoast "climate solutions" with each donation. Our organizations responded.

Scripps says climate change may represent "existential" threat to h...

"Other people have used the word catastrophic, but I have resisted doing so until now,” said the study’s lead author, Veerabhadran Ramanathan, a renowned climate scientist who helped influence Pope Francis to urge the world to fight global warming in 2015.

“I changed my mind because, over the past five years, I have gone back and reviewed data that we began collecting from satellites in the 1980s and data from aircraft and changes in the intensity of storms, and studies about the possible health affects of rapid global warming."

"The school published a paper that said there is a 5 percent chance of catastrophic change within roughly three decades, and a smaller chance that it would broadly wipe out human life."

"One does not need another person to agree in order for a fact to be true."

Not standing for the national anthem is a legal form of peaceful protest, which is a First Amendment right.

When a national figure refuses to stand for the national anthem, it shocks people into paying attention and generates conversation.

When one realizes the US does not live up to its ideals of freedom, liberty, and justice for all, refusing to stand for the national anthem is appropriate and justified.
