Is climate change for real?
Yes, scientists agree that the warming we are seeing today is entirely human-caused. Climate has changed in the past due to natural factors such as volcanoes, changes in the sun's energy and the way the Earth orbits the sun. In fact, these natural factors should be cooling the planet.
Is climate change real? The natural phenomena described above demonstrate that it is, but this is not the whole story. Human activities also affect climate, and a consensus of scientists are sure that the impact of these activities is playing an ever-greater role in determining what form Earth's climate takes.
Changing our main energy sources to clean and renewable energy is the best way to stop using fossil fuels. These include technologies like solar, wind, wave, tidal and geothermal power.
Each increment of warming results in rapidly escalating hazards, such as more intense heatwaves, heavier rainfall, and other weather extremes that increase risks for human health and ecosystems. Climate-driven food and water insecurity is expected to increase with increased warming.
Earth's temperature has risen by an average of 0.14° Fahrenheit (0.08° Celsius) per decade since 1880, or about 2° F in total.
Yes, the vast majority of actively publishing climate scientists – 97 percent – agree that humans are causing global warming and climate change.
The early 1980s would mark a sharp increase in global temperatures. Many experts point to 1988 as a critical turning point when watershed events placed global warming in the spotlight. The summer of 1988 was the hottest on record (although many since then have been hotter).
The answer to the question, “Is global warming real?” is yes: Nothing other than the rapid rise of greenhouse gas emissions from human activity can fully explain the dramatic and relatively recent rise in global average temperatures.

Without major action to reduce emissions, global temperature is on track to rise by 2.5 °C to 4.5 °C (4.5 °F to 8 °F) by 2100, according to the latest estimates. Thwaites Glacier. Credit: NASA. But it may not be too late to avoid or limit some of the worst effects of climate change.
Accelerating Clean Energy Ambition
While climate change cannot be stopped, it can be slowed. To avoid the worst consequences of climate change, we'll need to reach “net zero” carbon emissions by 2050 or sooner. Net zero means that, on balance, no more carbon is dumped into the atmosphere than is taken out.
How bad is climate change 2023?
2023: A record-breaking year
The past year has been a time of climate firsts, mainly for the wrong reasons. There have been over 38 days this year that were more than 1.5⁰C hotter than average – higher than any other year on record.
The authors point to four reasons why scientists disagree about global warming: a conflict among scientists in different and often competing disciplines; fundamental scientific uncertainties concerning how the global climate responds to the human presence; failure of the United Nations Intergovernmental Panel on ...

Some reject the idea that human-caused climate change exists; others have argued that human-made climate change is occurring but that the extent to which climate is changing and the precise impact of human activity is uncertain.
“The extraordinary global November temperatures, including two days warmer than 2C [3.6F] above pre-industrial (levels), mean that 2023 is the warmest year in recorded history,” Samantha Burgess, deputy head of C3S, said in a statement.
Over millions of years, Earth's climate has warmed up and cooled down many times. However, today the planet is warming much faster than it has over human history. Global air temperatures near Earth's surface have gone up about 2 degrees Fahrenheit in the last century.
At least five major ice ages have occurred throughout Earth's history: the earliest was over 2 billion years ago, and the most recent one began approximately 3 million years ago and continues today (yes, we live in an ice age!). Currently, we are in a warm interglacial that began about 11,000 years ago.
According to the poll, just over half of scientists (51%) believe in some form of deity or higher power; specifically, 33% of scientists say they believe in God, while 18% believe in a universal spirit or higher power.
Burning fossil fuels, cutting down forests and farming livestock are increasingly influencing the climate and the earth's temperature. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
Today, we have a clear understanding that our climate is changing rapidly, and that human activities are responsible for the vast majority of that change. NASA continues to send new satellites into space, and they also use aircraft, boats, as well as scientists on the ground, to gather important data.
Even after those first scorching millennia, however, the planet has often been much warmer than it is now. One of the warmest times was during the geologic period known as the Neoproterozoic, between 600 and 800 million years ago. Conditions were also frequently sweltering between 500 million and 250 million years ago.
Who was the woman who discovered global warming?
Eunice Newton Foote, who discovered the greenhouse effect and was a pivotal figure in women's rights movements, is the focus of today's Google doodle. The discovery of the greenhouse effect is often attributed to physicist John Tyndall, who carried out a series of experiments in 1859 looking at how heat affected air.
Climate shifts like heat waves could restrict the ability of people to work outdoor, and, in extreme cases, put their lives at risk. Under a 2050 climate scenario developed by NASA, continuing growth of the greenhouse emission at today's rate could lead to additional global warming of about 1.5 degrees Celsius by 2050.

Our oceans are dying
Half of the world's coral reefs have died in the last 30 years, and two thirds of the Great Barrier Reef have been damaged by coral bleaching – this happens when the sea temperature is too high. Whales, dolphins, porpoises and sea lions all suffer from bycatch from global fishing.
Over the last 100 years, the average temperature on Earth has warmed by 1°C. In our day-to-day lives, we may not notice much of a difference if the temperature went up by one degree, but this temperature rise has had a significant impact on the planet.
