I'll search for the latest scientific evidence on climate change to give you a grounded answer.
I've gathered evidence from NASA and the IPCC — now I'll compile the key findings on whether climate change is happening.
Yes, according to the overwhelming scientific consensus and evidence, climate change is real.
•The scientific consensus is clear: global climate change is real and humans are very likely the cause for this change
•There is unequivocal evidence that Earth is warming at an unprecedented rate. Human activity is the principal cause
Evidence cited by major scientific agencies:
•NASA and NOAA and other leading institutions agree that climate change is occurring and humans are driving it
•The Intergovernmental Panel on Climate Change (IPCC) stated: "It is unequivocal that human influence has warmed the atmosphere, ocean and land."
•According to the 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."
Background and key observations:
•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
•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
•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
•A scientific survey of more than 88,000 climate-related studies found that more than 99 percent of research agrees that climate change is real and primarily caused by human activities
NASA and other agencies point to multiple independent lines of evidence for rapid change, including:
Global Temperature Rise, Warming Ocean, Shrinking Ice Sheets, Glacial Retreat, Decreased Snow Cover, Sea Level Rise, Declining Arctic Sea Ice, Extreme Weather Events, and Ocean Acidification.
