Here maybe a great hope over the next hundred years... Carbon Capture... using none fossil fuels for power... Why nations are not nationalizing this tech and building the plants....

CO₂ removal can be done in two ways. The first is by enhancing carbon storage in natural ecosystems, such as planting more forests or storing more carbon in soil. The second is by using direct air capture (DAC) technology that strips CO₂ from the ambient air, then either stores it underground or turns it into products.
Engineers have built machines to scrub CO₂ from the air. But will it halt climate change?
Machines using giant fans and filters can literally suck carbon dioxide out of the air. Sounds great – but the technology faces many challenges.

MIT has one..
news.mit.edu
snip...
The device is essentially a large, specialized battery that absorbs carbon dioxide from the air (or other gas stream) passing over its electrodes as it is being charged up, and then releases the gas as it is being discharged. In operation, the device would simply alternate between charging and discharging, with fresh air or feed gas being blown through the system during the charging cycle, and then the pure, concentrated carbon dioxide being blown out during the discharging.
MIT engineers develop a new way to remove carbon dioxide from air
A system developed at MIT can efficiently capture the greenhouse gas carbon dioxide even from ambient air, and release it in pure, concentrated form. The carbon capture work was led by Sahag Voskian and T. Alan Hatton.

I found this Carbon Dioxide mixed with Hydrogen... make jet fuel....
www.fastcompany.com
Dimensional Energy plans to begin its process with CO2 captured from industry—for example, cement plants, which produce carbon dioxide as part of the chemical process even if they’re able to run on renewable energy. Eventually, as direct air capture technology scales up to pull CO2 from the atmosphere, it could also be a source for the fuel, making it essentially carbon neutral. (Direct air capture also produces water, which could be used to make hydrogen in the process.) Other sources are also possible. New technology that captures CO2 from trucks as they drive, for example, could theoretically be the source for new fuel for those trucks.

This is why we are not Venus, yet... Our oceans...
Ocean warming reaches new record over the past five years due to climate change. Ocean warming has risen to record highs over the last five years: just in 2019 the heat released into the world's oceans was equivalent to that of 5-6 atomic bombs per second. The culprit, no doubt, is climate change

Maybe, not nuclear winter but quickening of global warming...
If one nuclear exchange as described above occurs over the next 30 years, the net carbon emissions due to nuclear weapons proliferation caused by the expansion of nuclear energy worldwide would be 1.1–4.1g CO2 per kWh, where the energy generation assumed is the annual 2005 generation for nuclear power multiplied by

Our oceans will be hotter by 2050... Think of the Hurricanes that will be coming think how far up the east coast will be ravage by Hurricanes...
Oceans are getting hotter. Will the world be faced with dead oceans?
0.8°C
This pathway predicts a rise in global sea surface temperature of 0.8°C by 2050, and 1.2°C by 2100, relative to 1870–1899 temperatures.
www.statista.com
In 2020, the global ocean surface temperature was 0.76 degrees Celsius warmer than the 20th-century average. Oceans are responsible for absorbing over 90 percent of the Earth's excess heat from global warming. Departures from average conditions are called anomalies, and temperature anomalies result from recurring weather patterns or longer-term climate change. While the extent of these temperature anomalies fluctuates annually, an upward trend has been observed over the past several decades

According to a simulation of planetary warming trends, failure to drastically cut greenhouse gas pollution within the next half century could choke Earth's oceans for the next 100,000 years. With warmer temperatures reducing its ability to absorb oxygen, much of the water would become barren and lifeless. Oceanic food chains could be profoundly disrupted

.
If the world’s greenhouse gas emissions stay at the present rate, that means a 17% loss of biomass — the total weight of all the marine animal life — by the year 2100, according to Tuesday’s study in the Proceedings of the National Academy of Sciences. But if the world reduces carbon pollution, losses can be limited to only about 5%, the study said.

Global warming may reduce fish and other sea life by 17% by the year 2100
The world's oceans will probably lose about one-sixth of their fish and other marine life by the end of the century if climate change continues on its current path, a new study says.

AS the Glaciers go, the droughts will come... multitude of millions of people will suffer...
Asian glaciers will bring havoc as they melt away...
www.irishtimes.com
The impact of Himalayan glacial melting is significant because the region provides water to about 800 million people across Asia, who depend on seasonal run-off when the ice melts in the spring.
A different study, published last month in Nature, found that the level of meltwater production from Himalayan glaciers is about 1.6 times greater than the rate that would keep the glaciers in “balance”.
Here I show that seasonal glacier meltwater is equivalent to the basic needs of 221 ± 59 million people, or most of the annual municipal and industrial needs of Pakistan, Afghanistan, Tajikistan, Turkmenistan, Uzbekistan and Kyrgyzstan.

Summary: Beneath the cold, dark depths of the Arctic ocean sit vast reserves of methane. ... In its gaseous form, methane is one of the most potent greenhouse gases, warming the Earth about 30 times more efficiently than carbon dioxide.
New research, published on today in Geology, indicates that during the last two global periods of sea-ice melt, the decrease in pressure triggered methane release from buried reserves. Their results demonstrate that as Arctic ice, such as the Greenland ice sheet, melts, similar methane release is likely and should be included in climate models.
