3 de abr. de 2024 · The climate has changed many times during Earth’s history, but the changes have occurred slowly, over thousands of years. Only since the Industrial Revolution have human activities begun to influence climate—and scientists are still working to understand what the consequences might be.

9 de feb. de 2024 · Earth's climate is continually changing. Earth has been covered in ice (snowball Earth) at some points during its existence, while at others, Earth has been ice-free. Earth is now in a warming period, due in part to enhanced human emissions of greenhouse gases.
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. From global temperature rise to melting ice sheets, the evidence of a warming planet abounds.
25 de oct. de 2021 · Scientists and politicians say we are facing a planetary crisis because of climate change. But what's the evidence for global warming and how do we know it's being caused by humans?
A ccelerated human modification of the landscape and human-driven climate changes are fundamentally altering Earth’s surface processes and creating ecological challenges that scientists and policy makers are struggling to address.
