Let’s Begin…
As the Earth’s surface temperature gradually rises, it has become vital for us to predict the rate of this increase with as much precision as possible. In order to do that, scientists need to understand more about aerosols and clouds. Jasper Kirkby details an experiment at CERN that aims to do just that.

Science is never settled; it is always open to modification if new observations or experiments contradict the prevailing understanding. Do you think this lack of certainty is the strength or weakness of science, and why?

The openness of science to change is a strength. It means that as new evidence comes in, our thinking can improve. While this can create some bad stuff at times, it helps us change and critical thinking. In this, this movement helps us better fight issues, like climate change, leading to more correct knowledge and solutions.

I personally believe it's a strength of science. Science being open to modification if new discoveries are made means that it's an evolutionary process over time that helps us to understand our surroundings and ourselves, too.

The lack of certainty in science is a strength. It means science is flexible and can change when new evidence comes in. This adaptability helps us learn more and improve our understanding of the world. Being open to change is what drives progress and discovery.

Science changes with fresh data, demonstrating its ability to progress rather than a flaw. Changes can be difficult, yet they help us improve our understanding. Recognizing this process and based on proof updates helps to preserve confidence in scientific results.

In my opinion this lack of certainty is a weakness, because we can learn informations and then they can get modificated and we might don’t understand them. Also we can believe something thanks to opinion that isn’t 100% agreed, then we can make theories that aren’t true. Modificated theories can also disagree with some observations and then we can’t use informations that were confirmed earlier. That can make all scientist opinions wrong. People usually believe in scientists’ theories and they can disagree with new/ modificated theory. It’s really difficult when something gets modificated and we don’t know what opinion we should believe.

I think the lack of certainty is a weakness because if we get our calculations for the future wrong and act as per the wrong calculations then things could change drastically.

I think this lack of certainty is a strength, considering the fact that there's more and more to delve into and more to discover. If a scientist thinks they know everything about any given topic, there's seemingly no room to grow into when there might actually be a lot.

I think this is a strength because we will always have new things to learn and we will always be exploring new things.
