My post counted food crop decimation and coastal displcement.Nope that wasnt made clear where you referred to 'worldwide' concensus / wtte.
What you've missed there was your previous reference to your many 'billions' in lower latitudes. In contrast your reference above details
"Those who once lived on coastlines will face displacement and resettlement bottlenecks as they seek habitable places inland, according to new research".
That says nothing about your statement that there would be 'displacement of billions of people due to the reduced habitability through food production of many lower latitude nations' .
The point being the far greatest density of people is not in lower latitudes which you are going on about. You also need to check what your graphic says about climate change theoretically improving agricultural outputs worldwide ...
The above comes with the provisio that "The science however is far from certain on the benefit of carbon fertilisation". So like a lot of scientific projections then.
It also clearly states that:
This Map represents the case of beneficial carbon fertilisation processes
You may wish to compare that map based projection with the areas considered the major crop production areas across the globe ....
6 out of 8 of the most populated countries on the planet are projected to have their crops decimated - covering 4.1 billion people. 14 out of 20 of the most populated - covering 5.4 billion people (with 3.2 billion in the countries whose crops are decimated).
As requested, here is a contrast of current world crop yields versus the map showing crop decimation:
Huge areas of productive crop production will be decimated.
As usual, you never bother doing your own bloody research - just piss at others efforts and demand more.0 -

The effcts of climate change decimate crop production primarily in lower latitudes (mid to lower, to be more precise) - affecting mostly poorer nations:
And on the displacement of billions:Rising seas could result in 2 billion refugees by 2100https://www.sciencedaily.com/releases/2017/06/170626105746.htm
Date:June 26, 2017Source:Cornell UniversitySummary:In the year 2100, 2 billion people -- about one-fifth of the world's population -- could become climate change refugees due to rising ocean levels. Those who once lived on coastlines will face displacement and resettlement bottlenecks as they seek habitable places inland, according to new research.
The scientific consensus I referred to is that humans are pushing climate change.
Interesting article. I noted the following quote:
"Earth's escalating population is expected to top 9 billion people by 2050 and climb to 11 billion people by 2100, according to a United Nations report. Feeding that population will require more arable land even as swelling oceans consume fertile coastal zones and river deltas, driving people to seek new places to dwell." As you say those populations that are most at risk from the effects of climate change are located in the low latitudes (0 - 30 Degrees N/S).

Population is highest in the northern hemisphere at 25-26 degrees North latitude and 77-78 degrees East Longitude.

From the following article: https://www.foreignaffairs.com/articles/world/2018-11-29/climate-shocks-and-humanitarian-crises
"..throughout 2018, weather events also had devastating humanitarian consequences in developing countries, from immense floods in the Indian state of Kerala to an intense drought in Afghanistan that affected millions." ...
"Over the past decade, academics and policymakers have vigorously debated the question of whether climate change poses a security threat, with particular emphasis on whether it causes internal conflict. "
.."several risk factors make some countries more vulnerable than others to the consequences of climate change. Three stand out in particular: a high level of dependence on agriculture, a recent history of conflict, and discriminatory political institutions. Research suggests that in countries that display some or all of these risk factors, climate extremes are especially likely to lead to disastrous outcomes, including violence, food crises, and the large-scale displacement of populations."
"Countries facing the three aforementioned risk factors will struggle to deal with climate shocks. And one of the most serious of these shocks—especially in countries that depend on agriculture—is likely to be drought and water shortage. "
"The risk factors we identify are, naturally, not the only conditions that can contribute to instability and humanitarian crises. But unabated climate change is likely to amplify the challenges of these high-risk countries in decades to come. They will see more extreme consequences, and their already fragile governments will become even more hard pressed to manage violence and feed their populations. Understanding where instability is most likely to occur is an important first step to reducing risk."
The source might not be to everybody's taste.
"Foreign Affairs is an American magazine of international relations and U.S. foreign policy published by the Council on Foreign Relations, a nonprofit, nonpartisan, membership organization and think tank specializing in U.S. foreign policy and international affairs."
" Using data from the International Labor Organization, we defined a country as having a “high” level of agricultural dependence if at least 40 percent of its population worked in agriculture—a threshold that 66 countries met. In some countries, such as Malawi and Somalia, over 80 percent of the workforce is employed in agriculture."

Wow the alarmists are really digging deep with a wealth of old theoetical projections
We are all going to die or something !!!! Or maybe not ...
The moral of the story - dont listen to the usual alarmist rhetoric...
Thankfully we dont have to look too far to find some sanity. This in reaction to another extreme alarmist. Roger Hallam ...Many temperate regions will likely see increased crop yields under future climate, due to warmer temperatures and the CO2fertilization effect. Depending on the extent of global trade and cooperation, these yield increases could help to partially ameliorate decreases experienced elsewhere. Many agricultural impact projections don’t include the CO2 fertilization effect, due to uncertainty, but in reality this effect will probably help soften the blow of climate change to some extent. (For example, global wheat production may be more likely to increase than decrease; Liu et al. 2018 Global Change Biology1.)...
For example, over the historical period of global warming, technological advancements have increased yields by 100-200% in spite of any negative impact of climate change. Even if this yield trend were to reverse, the total production of calories might not be affected if economic forces cause more land to be used for agriculture. In other words, if yields were to be reduced by 10% that does not translate directly into 10% less food available. It is likely that the reduction in yield would stimulate increased land use for agriculture. In this example, if 10% more land were used for agriculture, total production would remain unaffected...
All these factors would need to be reckoned with before one could make any credible projection of reduced food production in the future,

"A quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25."
https://climate.nasa.gov/news/2436/co2-is-making-earth-greenerfor-now/
However it would be hubristic for an individual to use that information as a means to metaphorically crush their imagined opponents in a verbalistic joist before reading on:
"The beneficial impacts of carbon dioxide on plants may be limited, said co-author Dr. Philippe Ciais, associate director of the Laboratory of Climate and Environmental Sciences, Gif-suv-Yvette, France. “Studies have shown that plants acclimatize, or adjust, to rising carbon dioxide concentration and the fertilization effect diminishes over time.”
Perhaps then, on reflection they might realize that the path to truth lies not in vainglorious belief in their omniscience but rather humility and acceptance of their own fallibility and in that way they might find that we are all on the same path and absolute truth will forever elude us.
