Check CO2 and Temperature for up to date blog
Here’s temperature and CO2(carbon dioxide) correlation graph. It is very close relationship.
It also came in cycles and man’s impact was not much in this long term graph.
Irony is though. I would expected that co2 will make plants glow but it does opposite.
So, it is likely that it causes drought during summer and long winter due to more steam/cloud on other hemisphere.
Second graph is shorter term,
You can still see swings before 1800.
I guess what happens is that high temperature MELT the ice. Melting of ice changes the distribution of water from poles to equator as well as lowers the temperature.
I guess this increases tidal energy as well as more mass which cause increase in volcanic activity which probably block the sun a little and lowers temperature.
But you can see that cycle were close to 1000 years before, but now cycling in hundred years.
To me, cooling cause by 2nd stage of global warming is being cancel to large extent by excessive CO2 heating.
So we probably will not have cooling temperature cause by combo of ice melting/lower co2/volcanic activity and only volcanic remain.
So expect dry/drought in summer and longer harsher winter and extreme weather.
There is 11 year sun radiation cycle which got changed past year, we might be heading to 24,000 year low cycle which might be sign of ice age starting.
Sea level changes is not going to stop because CO2 level.
Extreme weather is not going change too much unless CO2 level are drastically reduced, which cannot happen without nuclear fusion power plants.
There are sun cycles etc. as well as comet affecting the weather.
As ice melt there will be change in water distribution and pressure. This also causes more active volcano. Probably at similar or larger to tidal impact level of star alignment.
