Ever-increasing CO2 levels could take us back to the tropical climate of Paleogene period. A new study has warned that unless we mitigate current levels of carbon dioxide emissions, Western Europe and New Zealand could revert to the hot tropical climate of the early Paleogene period -- 56-48 million years ago.

Its getting hotter every day and I would hate to think that science fiction becomes a reality to the point that drinking water is more valuable than gold.

Global warming is real. Scientists believe we have around a decade to take drastic action or the climate will change towards a path that cannot be undone. My own thoughts tell me that we are already there and it will just get worst.

Try living here in California, 40+ people dead from just the other day from a fire that I think is still burning right now.
We have the science and technology to create alternate sources of energy, seriously what are we doing about it? If the people in power want to put financial profit over the safety of the planet then maybe we need to do something about those in power. They want to be rich on a dead world maybe we should launch them all to the moon.
To answer the question it's man-made. Unfortunately we all aren't doing enough to stop global warming Some examples of what we could do are driving restrictions, cutting less from forests. Furthermore we need to invest more in renewable energy in such a way that it becomes way cheaper to produce.

Renewable energy is already relatively cheap to produce, with new onshore wind and photovoltaic generation being cheaper than new gas or coal infrastructure. The concern is more about whether it is reliable for nights and poor weather conditions. When you have to account for battery storage along with the renewables, it becomes more expensive. There are some workarounds, such as retrofitting existing hydroelectric dams to work in conjunction with solar arrays and run the water only during peak hours.

Can we limit global warming to 1.5 °C? Efforts to combat climate change tend to focus on supply-side changes, such as shifting to renewable or cleaner energy. Researchers now argue that demand-side approaches can play a crucial role given the aspirational target outlined in the Paris Agreement. Source 7s.
Could an anti-global warming atmospheric spraying program really work? A program to reduce Earth's heat capture by injecting aerosols into the atmosphere from high-altitude aircraft is possible, but unreasonably costly with current technology, and would be unlikely to remain secret. Those are the key findings of new research which looked at the capabilities and costs of various methods of delivering sulphates into the lower stratosphere, known as stratospheric aerosol injection (SAI).
