Is the global warming climate change things for real or a hoax?

The overwhelming scientific evidence and consensus indicate that global warming and climate change are real and not a hoax. Here are some key points that support this conclusion:

Temperature Records

Global temperatures have risen significantly since the late 19th century. The Earth's average surface temperature has increased by about 1.8°F (1.0°C) since 1880, with most of this warming occurring in the past 40 years14.

Multiple Lines of Evidence

Several lines of evidence confirm global warming:

• Rising global temperatures recorded by weather stations worldwide.
• Melting of mountain glaciers and ice sheets, such as those in Greenland and Antarctica.
• Decline in Arctic sea ice and Northern Hemisphere snow cover.
• Increase in global sea levels.
• Changes in migration patterns of birds, earlier blooming of plants, and shifts in the habitats of marine species14.

Human Cause

The scientific consensus is clear that human activities, particularly the emission of greenhouse gases like carbon dioxide, methane, and nitrous oxide, are the primary cause of the current warming trend. The increase in CO2 levels from about 280 parts per million in 1800 to over 410 ppm in 2019 is largely due to fossil fuel burning and other human activities124.

Scientific Consensus

Numerous studies and surveys have shown a near-unanimous agreement among climate scientists that human activities are causing global warming. For example, a 2021 study found that more than 99.9% of peer-reviewed scientific papers agree that climate change is mainly caused by humans25.

Natural vs. Human-Induced Changes

While Earth's climate has always changed naturally, the current rate of warming is unprecedented and cannot be explained by natural cycles alone. The rapid increase in greenhouse gases and the resulting warming are clearly linked to human activities, not natural processes134.

In summary, the evidence from temperature records, multiple lines of observational data, and the consensus among climate scientists all confirm that global warming and climate change are real and primarily caused by human activities.
