Is climate change real?

Is climate change real? I'll gather the latest scientific evidence to give you a clear answer.

Yes — climate change is real, and that conclusion is supported by overwhelming scientific evidence.

> There is unequivocal evidence that Earth is warming at an unprecedented rate. Human activity is the principal cause

What the science shows

1.It is happening now and is well-observed:

Earth-orbiting satellites and new technologies have helped scientists see the big picture, collecting many different types of information about our planet and its climate all over the world. Scientific information taken from natural sources (such as ice cores, rocks, and tree rings) and from modern equipment (like satellites and instruments) all show the signs of a changing climate.

2.The current warming is unusual:

While Earth’s climate has changed throughout its history, the current warming is happening at a rate not seen in the past 10,000 years.

The current warming trend is different because it is clearly the result of human activities since the mid-1800s, and is proceeding at a rate not seen over many recent millennia.

According to the Intergovernmental Panel on Climate Change (IPCC), "Since systematic scientific assessments began in the 1970s, the influence of human activity on the warming of the climate system has evolved from theory to established fact."

3.Human influence is unequivocal:

In its recent summary report, the IPCC stated that, “It is unequivocal that human influence has warmed the atmosphere, ocean and land… climate change is already affecting many weather and climate extremes in every region across the globe.”

The IPCC used its strongest terms yet to assert that humans are causing climate change, with the first line of its report summary reading: "It is unequivocal that human influence has warmed the atmosphere, ocean and land."

The fact that the IPCC has agreed — with the agreement of all 195 member countries — that it is unequivocal that human activity is causing climate change, is the strongest statement that the IPCC has ever made.

The body of peer‑reviewed science and major scientific organizations state unequivocally that recent warming is real and that human activity is the primary cause.

Key evidence of rapid climate change

NASA lists the evidence as compelling, including:

•Global Temperature Is Rising: The planet's average surface temperature has risen about 2 degrees Fahrenheit (1 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide emissions into the atmosphere and other human activities.
•Ocean Warming: The ocean has absorbed much of this increased heat... Earth stores 90% of the extra energy in the ocean.
•Ice and Snow Decline: Greenland and Antarctic ice sheets have decreased in mass, glaciers are retreating almost everywhere, and Arctic sea ice has declined rapidly.
•Sea Level Rise, Extreme Events and Ocean Acidification — From global temperature rise to melting ice sheets, the evidence of a warming planet abounds.

In short, natural climate variability has always existed, but the rapid warming observed since the mid-20th century cannot be explained by natural factors alone (such as solar or orbital changes) and is consistent with the heat-trapping effect of greenhouse gases emitted by human activities like burning fossil fuels and deforestation.
