I keep hearing that CCS has always been a failure and is continuing to be a failure.

So what are some promising technologies that you know to remove CO2 from the atmosphere that you think are scalable enough to help?

Thanks.

1. Coral Bleaching: One of the most immediate consequences of warming oceans is coral bleaching, which occurs when corals expel the symbiotic algae that give them their vibrant colors and provide them with energy. This process weakens the coral and leaves it more vulnerable to disease and death. Studies have shown that coral bleaching events are becoming more frequent and severe as ocean temperatures rise.

2. Changes in Marine Ecosystems: Warming oceans can also disrupt marine ecosystems by altering the distribution and abundance of marine species. Some species, such as fish and sea turtles, may move to cooler waters, while others may struggle to adapt to the changing conditions. This can lead to declines in biodiversity and changes in food webs that can have far-reaching effects on marine ecosystems.

3. More Extreme Weather Events: Warming oceans can also affect global weather patterns by altering the circulation of air and ocean currents. This can lead to more frequent and intense weather events, such as hurricanes, droughts, and floods. Studies have shown that ocean warming is linked to an increase in the frequency and intensity of tropical storms, as warmer waters provide more energy for these storms to form and intensify.

4. Rising Sea Levels: Finally, warming oceans can contribute to rising sea levels, as warmer water expands and glaciers and ice caps melt. This can have significant consequences for coastal communities, as higher sea levels can lead to increased flooding, erosion, and loss of habitat for coastal species.

Overall, a sudden spike in ocean temperature can have far-reaching consequences for marine life and global weather patterns. While the exact impacts will depend on a variety of factors, including the duration and severity of the warming event, scientists agree that we need to take action to address climate change and reduce greenhouse gas emissions in order to mitigate the effects of ocean warming on our planet."

There are several marine heat waves or ocean warming spots that don’t fit an El Nino pattern, such as those in the northern Pacific near Alaska and off the coast of Spain, he said.

“This is an unusual pattern. This is an extreme event at a global scale” in areas that don’t fit with merely an El Nino, said Princeton University climate scientist Gabe Vecchi. “That is a huge, huge signal. I think it’s going to take some level of effort to understand it.”

*Stopped in the sense that farmers couldn't even sow the rice.

For example one of the criteria to diagnose ME is to have Pots, which is a disease with very specific symptoms.

Pots is a disfunction of the autonomic system and it is often associated with gastroparesis.

I repeat, you are endorsing a very obsolete theory about ME.

This "believes" were entertained for a long time about ME but we have enough scientifical evidence that they were false.

Historically, this happened with multiple sclerosis, people with ms were labelled as fakers and ms was called "faker's disease".

Let's not go again to those horrible times today.

For an ample literature about ME I Invite you to visit the open medicine foundation website (the centre that studies ME at Stanford).

If you're recording a live opera it's a problem but then you usually have much higher quality gear without the limitations of a DSLR.

No, you are a loser who can't read reality. If you have a private jet you are just ignorant, in the sense that you ignore what is happening on this planet.

That's a cultural shift that we need to happen swiftly.

Of course, saying "we are doomed" is the easiest way to continue to do what we are doing. It's just a defensive mechanism at this point.

We should be stopping the production of plastic and replace it with bioplastics immediately.

Difficult? Yes. Impossible? No.

The car instead has a negative effect on our health and the infrastructure is much more costly and require much more maintenance, the pollution it creates has negative effects on our health too.

I am not opposed to nuclear, I think that anyone who is does not understand the severity of the climate crisis.

Problem will also be drought which will affect hydroelectric, we had this problem in Italy this summer.

The fact that economics hasn't still catch up with simple physics and biology is mind boggling. I mean that the religion of infinite growth on a finite planet has to stop.

Of course, we will "save trillions" if our ecological systems won't collapse.

We will save trillions of lives upon which we depend. We will also avert many food crisis due to drought (already happening here in Italy with -30% of the total agricultural production due to a drought).

And it's just the first step.

Not a small problem,you know...

Also some t shirts from the 90 are still looking good, which is kinda incredible.
