No global problem has ever been more exaggerated than climate change. As it has gone from being an obscure scientific question to a theme in popular culture, we’ve lost all sense of perspective.
Here are the facts: in Europe, emissions in 2020 were 26% below 1990 levels. In the United States, emissions in 2020 were 22% below 2005 levels. Emissions are likely to start declining, too, in developing nations, including China and India, within the next decade. Most nations’ emissions will be bigger this year than last, due to post-Covid economic growth. But global emissions are still likely to peak within the next decade.
And the result will be a much smaller increase in global average temperatures than almost anyone predicted just five years ago. The best science now predicts that temperatures are likely to rise just 2.5-3°Cabove pre-industrial levels. It’s not ideal, but it’s a far cry from the hysterical and apocalyptic predictions of 6°C, made just a decade ago. A 3°C increase is hardly an existential threat to humanity.
Not that you’d know it, if you had half an eye on the headlines this summer. The floods, fires and heatwaves that plagued the world were, for many observers, proof that the impacts of climate change have already become catastrophic. In Europe, more than 150 people died in flooding. In the United States, wildfire season started earlier and lasted longer, razing hundreds of thousands of acres. Around the world, hundreds died from heatwaves.
But again, it’s worth reminding ourselves of the facts: there has been a 92% decline in the per decade death toll from natural disasters since its peak in the 1920s. In that decade, 5.4 million people died from natural disasters. In the 2010s, just 0.4 million did. Globally, the five-year period ending in 2020 had the fewest natural disaster deaths of any five-year period since 1900. And this decline occurred during a period when the global population nearly quadrupled — and temperatures rose more than 1°C degree centigrade above pre-industrial levels.

Greta Thunberg rejects all ideas of the enlightenment. Despite what she wails, she is now living in the best times ever to be a child on planet Earth. She can actually go to FLOP26, something that few of us would want to do. Would she prefer to live in the worst of times when there was panic, suffering, environmental damage, death and no hope which she claims exists today?
We now eat better, are less affected by natural disasters and are able to cope with extremes of weather and climate. During the last 4 of at least 20,000 generations of humans, child mortality has decreased and global human longevity increased from 25 to 79 years. The climate moaners need to get some perspective from history.
The worst years to live since the time of Jesus were 535-550 AD because massive volcanic eruptions, perhaps Kamchatka or Alaska in 535-536 AD and Ilopango in El Salvador from 539-540 AD. The Northern Hemisphere atmosphere with filled with dust and acid sulphate clouds. These volcanic eruptions were coincidental with extraterrestrial impacts in March 536 AD in the Gulf of Carpentaria and elsewhere in August 536 AD. To make matters worse, these were at the time of a Solar Minimum.
The Sun was dimmed for 18 months, a white sulphuric acid aerosol cloud enveloped Europe, global temperature dropped by 1.5 to 2.5°C producing worldwide crop failures and death by starvation. There was migration (e.g. Slavic speaking people), political turmoil and the collapse of empires (e.g. Sasanian Empire in Persia). Tree rings show almost no growth for a few years.

Last year, wind and solar only produced 7.7% of India’s electricity. Coal on the other hand provided 72.1%.
12 GW of new wind and solar capacity have been added in the last 12 months, the equivalent of 16 TWh a year. However overall electricity consumption has been increasing at a rate of about 60 TWh a year, which means that coal generation will need to supply most of the gap..
This is a similar situation to China, where the construction of wind and solar farms cannot keep up with rising demand.
In FY 2020/21, a further 4.9 GW of thermal capacity (nearly all coal) was added, increasing existing capacity by 2%. This should generate about 30 TWh a year.
