The BBC's analysis department examines whether the UN goal of limiting global warming is still achievable.
The UN Secretary-General caused a few laughs at COP27 when he started reading the wrong speech.
His staff quickly provided him with the correct paperwork and explained that he would be meeting with a group of youth delegates later that day and that this speech was for that event.
The former British Prime Minister said he was in a "supporting role" to current Prime Minister Rishi Sunak at the COP27 climate summit.
Boris Johnson was asked if he was concerned when Sunak initially said he would not be attending the conference in Egypt on November 17 due to the UK government's budget preparations.
Johnson replied: "The Prime Minister is here. I'm glad he's here. He gave a remarkable speech the other day. He is absolutely on the right track."
He added that he attended the conference as "a Conservative Party foot soldier and spearman, just in a supporting role to remind the world of what we did in Glasgow".
Scientists say climate change is making more than half of all infectious diseases worse; and the World Health Organization says humanity must "prepare" to combat this threat to global health security.

According to the UN, around 11 million tons of plastic waste enter the oceans every year.
On the International Day Without Plastic Bags, People correspondent Stephanie Hegarty questions the effectiveness of plastic recycling efforts.
She notes that even in countries where a lot of plastic waste is collected, only a fraction of it gets recycled. Some may be sent to a developing country where they meet an unknown destination. Some, for example in Germany, can be burned.
And when a plastic bottle is recycled, it can be turned into products like food trays or fabrics that are much less likely to be recycled at the end of their life.

It is claimed that large expanses of ocean must be protected from human activity in order for them to regenerate.
