Climate change can affect our health, ability to grow food, housing, safety and work. Some of us are already more vulnerable to climate impacts, such as people living in small island nations and other developing countries.
We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves. Scientists predict global temperature increases from human-made greenhouse gases will continue. Severe weather damage will also increase and intensify.
Global warming causes climate change, which poses a serious threat to life on Earth in the forms of widespread flooding and extreme weather. Scientists continue to study global warming and its impact on Earth. greenhouse gas produced by animals during respiration and used by plants during photosynthesis.
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.
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 ...
2023: A record-breaking year
This follows a warning from the World Meteorological Organisation that 1.5⁰C of warming will start to become the norm in the next five years – and become permanent by the mid-2030s. Meanwhile, the oceans have also been rapidly heating up.
All continents will be affected
Even the majority of the world's warmest and wettest regions have a wet bulb of no more than 25 to 27°C. In 2050, scientists estimate that it will be very difficult to live in South Asia and the Persian Gulf, i.e. countries such as Iran, Kuwait and Oman.
“While we are predicting an uninhabitable planet in 250 million years, today we are already experiencing extreme heat that is detrimental to human health. This is why it is crucial to reach net-zero emissions as soon as possible,” Lo added.
How bad is climate change 2023?
Summer of 2023 was Earth's hottest since global records began in 1880, according to scientists at NASA's Goddard Institute of Space Studies (GISS) in New York.
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.

It seems that life on Earth is adapted to tolerating a changing climate to some degree, and this is evidence that climate changes, but our own experience of climate throughout our lifetimes, along with scientific records, also proves that climate change is happening.
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.
Extreme heat waves, in fact, are expected to last longer and impact more communities as the climate continues to warm. By 2050, the nonprofit assessing climate change risk predicts an “extreme heat belt” to wrap around the southeastern and western United States, affecting over 107 million residents.
Holding temperatures to 1.5 degrees Celsius will require a clean energy transition to be far advanced by 2030. And the 2022 IPCC report made it clear that to keep temperatures to 2 degrees Celsius we have until 2050 to largely decarbonize the global economy.
These catastrophic impacts include sea level rise from melting ice sheets in Greenland and Antarctica that would flood most major global coastal cities; increasingly common and more severe storms, droughts, and heatwaves; massive crop failures and water shortages; and the large-scale destruction of habitats and ...
Yes, the vast majority of actively publishing climate scientists – 97 percent – agree that humans are causing global warming and climate change.
- China. China is the largest emitter of carbon dioxide gas in the world, with 11,336 million metric tons emitted in 2021. ...
- The United States. The U.S. is the second-largest emitter of CO2, with 5,032 million metric tons of total carbon dioxide emissions in 2021. ...
- India. ...
- Russia. ...
- Japan.
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.
Will summer 2024 be hotter than 2023?
“We anticipate that 2024 is going to be an even warmer year because we're going to be starting off with that El Niño event,” said Gavin Schmidt, a Nasa climate scientist. “That will peak towards the end of this year, and how big that is is going to have a big impact on the following year's statistics.”
June-August 2023 was also the Northern Hemisphere's hottest meteorological summer on record, at 2.59 degrees F (1.44 degrees C) above average. The season, which also marks the Southern Hemisphere's winter, was the Southern Hemisphere's warmest winter on record at 1.53 degrees F (0.85 of a degree C) above average.
In a paper published in Nature Climate Change, we show that the Earth has been getting greener over the past 30 years. As much as half of all vegetated land is greener today, and remarkably, only 4% of land has become browner.
In other words, while the island country will likely face worsen effects from climate change, they have proven to be better and more willing to adapt to recover. All five Scandinavian countries – Denmark, Finland, Iceland, Norway, and Sweden – are also listed in the top 10 of the ND-GAIN Index.
