When Did Global Warming Start?

If global warming began millions of years ago, the first signs of global warming may not have been seen until much later.

The first signs of climate change may have appeared millions of years ago, even if they're not as dramatic as they seem today.

While scientists debated the causes of global warming, most scientists agreed that more research was needed to understand it better.

In order to answer that question, research activity accelerated with massive data-gathering schemes involving international fleets of oceanographic ships and orbiting satellites.

Soon, the ice-age warnings grew less frequent. Now, scientists were focusing more attention on the effects of human activities on the earth's climate.

Humans are responsible for much of the dust and smog we create in the air, and those particles linger for weeks and even decades.

In the early 1970s, the global annual mean temperature began to rise.

Even though climate change was a relatively recent phenomenon, it was still significant and a major event in our planet's history.

In the early 1970s, the global annual mean temperature began to rise.

The ensuing global warming era was characterized by major events like Flooding, Wildfires, Heat Waves, Hurricanes and droughts.
