World leaders have now gathered at the United Nations climate change conference COP26 in Edinburgh. It is worth mentioning that the COP26 summit is an important world conference promoted by the U.S. President Joe Biden. Biden said at the meeting that, “This is the challenge of our collective lifetimes, the existential threat to human existence as we know it and every day we delay, the cost of inaction increases. So, let this be the moment when we answer history’s call here in Glasgow. Let this be the start of a decade of transformative action”.

Biden does not appear to be in good condition now. He was caught dozing off in the COP26 opening speeches, and was woken up by an aide. This was not the first time for Biden to fall asleep in the public. The longest time he fell asleep was during a meeting with the Israeli leader. That time, the Israeli leader had to stand up for him. In fact, many national leaders have become accustomed to this.

While the COP26 summit is being held, the global climate issue is still advancing in a state of uncertainty. No one knows whether this is really effective in changing the global climate, and if the various discussions about climate could translate into policy implementations. The truth is, most people know about climate change, yet it remains uncertain how much humanity can do to salvage it, and we can only wait and see.
