How do we Know Human are Causing Climate Change?

AI Overview

Yes, the vast majority of scientists agree that human activities are the Primary driver of current climate change. Specifically, burning fossil fuels, deforestation, and agricultural practices release greenhouse gases into the atmosphere, trapping heat and causing the planet to warm. This increase in greenhouse gases is amplifying Earth's natural greenhouse effect, leading to a warming trend.

Here's a more detailed explanation:

• Greenhouse Gas Emissions:
  .Opens in new tab
  Burning fossil fuels (coal, oil, and gas) for energy, transportation, and industry releases massive amounts of carbon dioxide (CO2) into the atmosphere. Deforestation and land-use changes also release CO2 and other greenhouse gases like methane. Agricultural practices contribute to emissions from livestock and fertilizer use.
• • The Greenhouse Effect:
    .Opens in new tab
    Greenhouse gases trap heat in the Earth's atmosphere, preventing it from radiating back into space. This natural process is crucial for maintaining a habitable planet, but human activities have significantly intensified it, leading to a warming trend.

  • Evidence of Warming:
    .Opens in new tab
    Scientists observe a clear correlation between increased greenhouse gas concentrations and rising global temperatures. Data from weather stations worldwide, satellite measurements, and climate models show a consistent warming trend, with average global temperatures rising by about 2 degrees Fahrenheit (1 degree Celsius) since the late 19th century.

  • Human Influence:

    Studies have shown that human activities are responsible for nearly All global warming over the past 200 years. The rate at which CO2 from human activities is increasing is much faster than natural sources, such as after the last Ice Age.

How bad will it get?

How bad will it get?

MY opinion, Not you and the deniers/'skeptics", is being affirmed.
It's getting warmer .. and warmer faster as CO2 rises and "we are in the oven waiting to cook through."
With Both TCR AND ECS of the last 100, 50, 10 years, not only kicking in, but growing with CO2 PPM increases every year.

Hard to predict exact years (a suckers ploy) as there is no precedent for our 100-200x faster PPM increase than natural causes, but it's worrisome for the educated. Alarming to Hansen who's issued new accelerated predictions.

What's the worst thing that will happen?

 

[jc456]

Yes, I believe they are and that we are headed for 500PPM by 2050.
But even if they were the same or down 20%, or even 50%, the PPM would still be increasing as CO2 is basically Cumulative at these Carbon Cycle busting levels.
(Not to mention the similar increase of 80x more powerful CH4/Methane.)
