In general, it is true the global climate is getting warmer because humans are emitting greenhouse gases (GHG). The use of timescales may help address this problem. The climate systems of the El Niño-Southern Oscillation or volcanic eruptions events use interannual scales to monitor the variability of their patterns over the course of years. However, human GHG emissions are rising above natural fluctuations, and temperatures continue to increase, so monitoring needs to be continuous. This is not a matter of economic interest or conspiracy. All the data is available for everyone to see; these two points are not controversial in the scientific community but are more of a topic of popular science and political hurdles. The issues that scientists are exploring now are how much warmer the future will be, what consequences the warming will have, and how should we respond. There is no consensus on these specific issues, but a large number of reviews and comparative studies and multinational research are being conducted to form a consensus from reliable resources. For each scientific study, researchers are not studying the topics of global warming or climate change; but the cloud formation process, the atmospheric trace gas inversion, or the marine plankton dynamics in the atmosphere. There are experts on subjects like the remote sensing of land vegetation or glacial dynamic models, but no one is an expert on global warming expert. Fortunately, the understanding of global warming or climate changes only requires scientific common sense. Various disciplines already have evidence on the effects of warming in recent decades. People have a negative outlook believing it to be irreversible and it will lead to catastrophic consequences. This topic has only gradually become a concern. In order to predict and respond accordingly, people have to organize scientist-government communication platforms, like the IPCC, create new interdisciplinary projects, or be informed by professional magazines like Nature Climate Change. Resolving this issue requires negotiations on a multinational level. As a political issue, intergovernmental cooperation can stimulate public imagination by turning it into a media topic (mainly in Europe and the United States). At the same time, there will be some interest groups that will attack and discredit each other, to create conspiracy theories.
The dust has settled at COP27, the 27th United Nations Climate Conference at Sharm El-Sheikh in Egypt where a record 45,000 people registered to attend. The longest running summit of all the conferences, agreements made in the final moments has left us all with hope but also doubts.
