Solar activity was low in recent years, but its increase can actually change global mean temperature by about 0.4 centigrade ( between solar minimum and maximum). The next Solar Maximum is expected in 2025. Camp, C. D., and Tung, K. K. (2007), Surface warming by the solar cycle as revealed by the composite mean difference projection, Geophys. Res. Lett., 34, L14703, doi:10.1029/2007GL030207
On 13 June 2022 long duration solar flare erupted producing large Coronal Mass Ejection which partly only reached the Earth surface. Apparently this day 125 millions of Americans were under heat warning. large part of US been affected, temperature feels like reached over 40 Centigrades. Sunspots number in Summer 2023 was reaching 200 and severity of heat related phenomena increased.
During very low Solar Activity known as Maunder Minimum , a period of significantly reduced solar activity from 1645 to 1710. the total solar irradiance decreased by 0.22%, leading to a drop in the average terrestrial temperature in the northern hemisphere by 1.0 – 1.5 °C (1.8 – 2.7 °F). That was five cycles in raw so if it would be one cycle would make 0.3 centigrade change. The same value change should be expected between Solar Minimum and Maximum, This resulted in frozen rivers, and colder winters and summers1.Additional facts:
Ozone hole in 2021 was relatively large and long-lasting. I suppose that its presence is actually triggered by weather pattern. Antarctic is encircled during winter by strong low pressure systems (finaly cyclones) therefore the air is pushed away from the center (above Antarctic), there is not enough oxygen to form ozone. Higher temperature of ocean in relation to low temperature of Antarctic drive this pattern. It means that in warmer world we can see more ozone layer loss. Recent winter was many deep lows (cyclones) in Northern Hemisphere ass well. Apparently it is high concentration of methane in upper atmosphere that make thing worse. It could be a vicious circle as ozone presence is needed in atmosphere for hydroxyl radical to occur which according to scientist's is shortening methane live in atmosphere. Recent research published in nature: Climate Change favours large seasonal loss of Arctic ozone, published in 23 June 2021 doi.org/10.1038/s41467-021-24089-6 shows that Earth rising temp makes ozone loss worse.
China announced its goal of zero CO2 emission in 2060 which seem to reflect timeframe within their own coal proven reserves finish https://www.worldometers.info/coal/china-coal/#coal-reserves it is not an answer to the climate emergency. They had to invest a lot in coal power plants in the past years as generated 250% more power from coal in 2011 than in 2000, has it at risk of stranded assets - not bringing expected profits, so they are reluctant of cutting emission for now. Industry in China is consuming the most of energy. FROM 1979 TO 2017 CHINA ATTRACTED 2 010 BILLION USD (OVER TWO TRILLION US DOLLARS) of foreign direct investments. China could reduce much of its 10Gt (billion tons) CO2 emission if investors would install photovoltaic or wind power systems to meet their energy demand. Around 60% of total yearly foreign direct investments in China are coming from Hong Kong - global financial centre. Other big investors are EU, Japan, Singapore, USA, Virgin Islands. Half of it is manufacturing could be funded by venture capital VC or private equity PE possibly by companies listed here equalocean.com/analysis/2020022013686
Installation of the photovoltaic power system would help manufacturers cut costs in the long term so it should be in their interest. It could speed up the transition. It may work elsewhere as well.

If you live in a big city, you can check out my video – it is a short trip - 15 min quest to beaver's pound.
The forest I know the biggest in my country it is mainly pine, somehow these trees have no much branches. Is planted dense (then gradually cleared)- it could be not enough light and water, therefore low branches dried. It could be too dense for birds to access trees affected by pests - possibly sawfly but could be pine processionary. As II can see now after two years of drought pine is drying losing part of its needles, spruce is less common but is usually thriving. This is state forest and trees are for timber purpose. They could choose pine as it has fewer branches (it could mean less laborious in processing) anyway comparable to spruce, but recent drought made this forest start dying. Taking into account the problem of CO2 concentration you have to rethink how this forest is managed as spruce is more resistant to drought it would be better to plant it, have it more in this forest. Oaks leaves are commonly dried. Additionally, some small water pounds dried out as well as small streams so some animals may need travel longer distance to find water. Nearest weather station recorded 30% less rainfall in 2020 than in 2000 from January to August (160 litres less rain per square meter, in 2019 it was 244 litres less in the same period ) it could not be without impact on the trees. In near future, a wildfire could happen. As elsewhere these were almost unstoppable here can be the same. The fire spread faster if drier it is so even having enough resources it quickly becoming a life risk for firefighters to suppress it. If we stop emission there would not be an excessive concentration of CO2 during winter which is causing radiation forcing to raise and the dry condition persists (here 46% less precipitation from January to March). Therefore drought and wildfires in future can be less extensive but only if we cut noticeably emission.
Wildlife have they say about peoples destructive way of life. Woodpecker excavated holes in the wooden bottom part of the roof's side in surrounding buildings as it was disturbed by partial logging - consisting of many single trees in effect making it less dense. This bird has very good hearing so the noise of chainsaw is probably horrible for him and of course, is worried that his habitat is under threat. https://www.weatheronline.co.uk/weather/maps/city?FMM=1...
