The current world population of 7.3 billion is increasing by 83 million a year. It will reach 8.5 billion by 2030, 9.7 billion by 2050 and 11.2 billion by 2100, assuming UNPD’s medium variant projection is accurate. If, however, a higher fertility rate prevails this century, there would be 16.6 billion people by 2100, assuming another global doubling is supportable.

India will overtake China as the most populous country in seven years. By then, India's population will have increased five-fold - from 250 million in 1950 to 1.4 billion.

Africa’s population will double in the next 35 years. By 2100, almost 40 percent of the world’s population will live on this one continent. Nigeria, with only 52 million people in 1950 and 170 million today, is projected to reach 400 million by 2050, an eight-fold increase in a century.

By 2100, India could have a population of 1.6 billion, but China’s numbers are projected to decline by about 30 percent to one billion people. However, an increase in average fertility of just 0.50 children per woman this century - as assumed in UNPD’s high variant projection – would see India with 2.6 billion people in 2100, and China with 1.6 billion.

Dealing with climate change is just not that hard! The first step is to isolate all those with a vested interest in the cause, namely those who have a commercial interest in the consumption of dirty carbon creating fossil fuel!

And then set about changing outcomes! And to be fair, allow those using coal and other dirty fossil fuels to sequester the carbon they create.

And given if they sequester it in oil rich carbon absorbing algae, to create a new source of income/profit.

Only the most rigid recalcitrant would make a problem in achieving something called clean coal.

After clean coal there's clean energy, which should include broad scale carbon free solar thermal plants, or very local energy, reticulated within a narrow target market via carbon free thorium reactors, which given energy dependant industrial applications ( steel and aluminum smelting, ship and sub building, car manufacture, miniature truckable power plants) could more than halve the cost of industrial power!

After which we have endlessly sustainable carbon neutral biogas>ceramic fuel cells, which which to power the whole domestic economy, with baseload power for less than quarter what we mugs fork out now. It's just not that hard to decarb an economy, and all while massively improving our economic performance!

Simply put, a climate changed future is so fraught, we simply cannot allow a few very powerful voices to decide our future, with more of the same that created our current problems to begin with!

"Half a century ago, the cause célèbre was dangerous anthropogenic population change. So why is climate alarmism now centre-stage?"

I honestly think you answered your own question.
How many times must I say it?

Armchair, saying it an infinite number of times wouldn't make it true!

I'm baffled as to how anyone could take seriously the allegation that Global Warming's a hoax invented in 1990 by the Club Of Rome. It's an observed phenomenon, and I was aware of it in the 1980s even if you weren't.

What would It take to convince you to abandon the hypothesis that it's coincidence the world's warmed while we've increased atmospheric concentrations of a gas known to cause warming?

Aidan, wrong on ALL counts, Syria's population tripled over the last 40 years, 18 years of global cooling, NO sea level rise & crops increasing in productivity from the extra CO2.

How does 18 years of global cooling equate to 2015 being the hottest year on record??
Am I missing something?
