In a nutshell

Recently. my feeling is going up and down by considering many things. To be honest, I can't keep up with them though, but I often can't break out of my shell. I tend to behave without thinking about prior things.  Should contemplate and articulate more...
Don't you think it's just a waste of my time spending think them by myself and so stupid not to trust friends ?? Absolutely, all of them are my faults and points that I need to improve. So, I mean this week was so restive that couldn't concentrate on my work. whatever, as a routine, I watched "in a nutshell" as well, which title is "誰が気候変動の責任者ですか？ –誰が修正する必要がありますか"？  

Responsibility for climate change cannot be attributed to any individual person or group. Climate change is the result of a complex interplay of factors around the world, affecting many people and activities.

Scientific consensus suggests that human activities have a significant impact on global warming and climate change. In particular, emissions of carbon dioxide (CO2) and other greenhouse gases from the combustion of fossil fuels are considered a major factor. This involves a variety of activities, including industrial processes, energy production, transportation, and deforestation.

Therefore, responsibility for climate change is shared not only by individual people and organizations, but also by governments, businesses, and the international community as a whole. One international framework is the United Nations Framework Convention on Climate Change (UNFCCC), the United Nations framework for promoting climate change action. The Convention aims to promote measures to reduce and adapt to global warming, and countries around the world are participating in it.
