How do scientists predict future in climate

Using trend patterns of a country and their climate (on average over the past 30 years) also Global Warming and the effect of the climate change may change and trend graphs could be used differently

either a donut or a sphere or a pancake or a flat sphere. it depends on where the vertical line is.

if the line goes through the center of the circle and is perpendicular to a diameter containing the center, then you get a flat circle.

if the line and the diameter of a the circle meet in the center of the diameter and at an angle, you get a pancake.

if the line is on the circumference of the circle and is at right angles   to the circle you get a ring.

if the line contains the diameter, you get a sphere.

the the line is parallel to the diameter and touches the circumference, you get a donut.

yes? ? what is your question lol cos this isnt
