Can you cite a peer reviewed scientific paper that supports your idea, that Earth will become unlivable, unless we change our ways?If we refuse to address the negative human effects on our environment the earth will become unlivable for the current population as the oceans rise, the weather becomes too unpredictably violent for life and agriculture and the atmosphere heats up.
What we have been doing is not enough if we expect to be able to live at our current standard of living. Either we can change or the earth changes and one-quarter to one third of the population and 1/3 of the species are wiped out by disease, flooding and famine and environmental upheaval.
What does the Science tell us?
The observed data shows that increases in CO2 levels can cause some warming.
A doubling of the CO2 level would force warming of ~ 1.1C, and that first doubling would take about 180 years.
A second doubling, may be possible, but only if we dug up and burned every bit of coal we can find,
AND we do not improve emissions through technology.
I am by no means saying that Humans do not have a negative effect on the environment, we do!
Human effects on the climate is not the same thing, and much more difficult to measure.
Whatever is happening to the climate and for whatever reason, it is having the opposite effect than you claim.
Your claim,
"the weather becomes too unpredictably violent for life and agriculture"
The data!
World Population Growth - Our World in Data
The world population increased from 1 billion in 1800 to 7.7 billion today
We don't need to double world food production by 2050 – here's why
and the global food supply is increasing.
Your first two points are factually incorrect! There are not negative effects, as we are still increasing both population and food supply.
Your second paragraph is almost as wrong as your first,
"What we have been doing is not enough if we expect to be able to live at our current standard of living. Either we can change or the earth changes and one-quarter to one third of the population and 1/3 of the species are wiped out by disease, flooding and famine and environmental upheaval."
our current standard of living is based on easy access to energy. Currently that easy access comes from fossil fuels, but that is unsustainable,
and would not even scale up to the current population.
It is the global warming alarmist, who would demand that we lower our standards of living,
be forced to live in small apartments near public transportation. This may work for people who want that lifestyle,
but not so much for people who want to raise their families outside of the inner city.
So on your second paragraph point,
Can you cite a scientific paper that supports your assessment of the future, and on what criteria is it based?
