The Glasgow climate summit has again brought a lot of promises of future actions in combatting climate change. Nations have agreed to stop deforestation by 2030, to generate carbon-free shipping and to become carbon-neutral generally by 2050 (except for India by 2070). However, so far virtually everything is just talk of future actions. And even the promises fall short of the 1.5oC temperature increase limit, which is the preferred target of the 2015 Paris Agreement. At present, the promises made (for 2030) would limit the temperature increase to 2.4oC.
And these are almost totally just promises. Since the electricity use has increased markedly in the 21st century, the proportion of it produced using renewable sources has increased only about two percentage points, from 37 to 39 %. Many countries, such as Australia are building new coal mines and oil exploration continues virtually everywhere. The social media are filled with climate-denialist propaganda, and what is very worrying is that close to 20 % of the biggest oil product companies are running ads with misinformation about climate change. Many Facebook and Twitter users believe these ads. In contrast, they say that scientists are spreading lies about climate change. It is amazing that after the heat waves, wildfire, storms and floods of this year, about 45 % of people, e.g., in Finland deny that there is any human influence on climate – and Finland is supposed to have high education level.
The fact that it is all promises with little action is shown by a couple of examples. In COP26 an alliance committing to ending oil and gas extraction was formed. As members it has Costa Rica, France, Denmark, Ireland, Sweden, Quebec, Wales and Greenland. None of the countries are significant oil and gas producers and only Denmark has committed to immediately stop issuing new oil and gas licences. The other countries have not set a date to when they will stop permitting new oil and gas projects. In Finland subsidies of peat extraction were not stopped and worldwide subsidies to fossil fuels amount to hundreds of billions of euros. An alliance for generating non-carbon shipping by 2030 has been formed, but present changes from the use of diesel oil to the use of LNG actually increases greenhouse effect, because of the engine type used. The greenhouse gas emissions could be curbed by a different type of engine. However, they would cost more, as they require catalytic converters for removing nitrogen oxides.
It appears that despite their urgency, climate actions are not accepted, if they cost anything. This is a huge problem, since a small cost now could prevent a huge, if not insurmountable cost by 2050.
