I would imagine that most here believe in global warming. My question is what effect does the sun have on global warming because the heat increases as it's fuel is consumed.
A typical answer would look like this:My question is what effect does the sun have on global warming because the heat increases as it's fuel is consumed.
Simon Bridge said:A typical answer would look like this:
"...the Sun's output changes so slowly and solar variability is so slight (less than 0.00425% of the total energy per year on time scales of days), that continuous monitoring by state-of-the-art instrumentation is necessary to detect changes with climate significance. Scientists theorize that as much as 25% of the 20th century anticipated global warming of the Earth may be due to changes in the Sun's energy output. Systematic changes in irradiance as little as 0.25% per century can cause the complete range of climate variations that have occurred in the past, ranging from ice ages to global tropical conditions. For example, scientists believe the "Little Ice Age" that occurred in Europe in the late 17th century could have been related to the minimum in sunspot activity (and a correlated minimum in total solar irradiance) that occurred during the same period."Note that this is not due to "heat increases as its fuel is consumed" - the output of the Sun varies anyway.

Give us the best one you got.
And it appears to me that you are misunderstanding what happened in the thread and focusing on a specific word. Basically, the OP in that thread was asking for support against non-scientific arguments. That's not the purpose of PF, as you should have noted in the rules when you joined. We are not here to debunk nonsense.CapnGranite said:"This is not a question of perspective, and we are not a forum about "perspectives" here, we are a science forum. I closed the thread."

This is, to me, an egregious abuse and lack of understanding of the scientific process.
This thread has veered off far away from the causes of global warming and will remain closed.Drakkith said:Thread locked for moderation.
Global warming refers to the gradual increase in the Earth's average temperature due to the buildup of greenhouse gases in the atmosphere. These gases, such as carbon dioxide, trap heat from the sun and prevent it from escaping into space, leading to a warming effect on the planet.
The main cause of global warming is the increase in greenhouse gases, primarily carbon dioxide, from human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release large amounts of carbon dioxide into the atmosphere, trapping more heat and contributing to the warming of the planet.
Human activities such as burning fossil fuels, deforestation, and industrial processes release large amounts of greenhouse gases into the atmosphere. These gases trap heat from the sun and contribute to the warming of the planet. The burning of fossil fuels for transportation, electricity, and heating is the largest contributor to greenhouse gas emissions.
The consequences of global warming include rising sea levels, more frequent and severe natural disasters, changes in weather patterns, and negative impacts on ecosystems and biodiversity. It can also lead to food and water shortages, displacement of communities, and health concerns. These consequences can have significant economic, social, and environmental impacts.
To address global warming, it is essential to reduce greenhouse gas emissions. This can be achieved by transitioning to renewable energy sources, increasing energy efficiency, and implementing sustainable land-use practices. Individuals can also take action by reducing their carbon footprint, such as by using public transportation, eating a plant-based diet, and supporting organizations working towards mitigating climate change.
