The ten hottest years ever recorded all happened since 2010 and the hottest one of all was 2016.
declares that fluctuations in solar activity do not correlate with
the rapid increase in global temperatures over the last few decades.
A report from the Intergovernmental Panel on Climate Change (IPCC) in 2007, which was based on the work of some 2,500 scientists in more than 130
countries, concluded that humans have caused most if not all of the current global warming.
More specifically, the official scientific opinion on global warming is that it is occurring right now, and that it is more than 90% certain that human activities are causing it due to greenhouse gas emissions (according to the IPCC's Fourth Assessment Report in 2007).
Although the media will give the illusion that there is still a debate on climate change, 97-98% of climate scientists affirm
the tenets of anthropogenic global warming (this data originates from the Proceedings of the National Academy of Science which took into account 1,372 scientists). What is more, the study shows that the average expertise of
the 2-3% who deny man-made climate change was much below that of their colleagues, based on
both publication and citation rates.
Since climate change will affect the biosphere, every single ecosystem and every single species therein will be affected in one way or another.
As a matter of fact, more than a million species could face extinction.
Climate change will cripple economies worldwide by causing several billions of dollars in damages from natural disasters such as droughts and hurricanes; sea levels arise could cause trillions of dollars in damages alone.
A positive feedback effect could make global warming uncontrollable
after a certain point.
Scientists predict that a 1 meter sea level rise is well in the range of possibilities. This sea level rise is due to both thermal expansion of water as well as melting ice (land ice in Greenland and Antarctica mostly). One estimate is that the range of sea level rise may be between 0.3 and 2.5 meters, depending on how much climate mitigation is done.
The Arctic could become ice free by as early as 2035 (Source).
Temperatures have risen by at least 1.1 degrees Celsius since preindustrial times, according to NASA's Goddard Institute for Space Studies. Carbon dioxide levels have reached at least 420 ppm (Source).
In Alaska, western Canada, and eastern Russia, average temperatures have
risen at twice the global average, according to the multinational Arctic
Climate Impact Assessment report which was compiled between 2000 and 2004. Greenland and the Arctic are being even more affected.
In the Northern
Hemisphere, freezes begin a
week later and thaws come out a week earlier in spring.
Coral reefs, which are very sensitive to even small changes in water temperature, have been severely affected. Coral reefs are affected by ocean acidification. Coral reefs are not just pretty; they play a vital role in the ocean's ecosystems. When they bleach, the entire marine food chain will be ultimately affected.

There is a difference between climate change and global warming, despite the two terms being used interchangeably by the media. The former term is the more accurate and scientific one as it includes changes in sea levels, precipitation, and wind patterns.
China and the United States are the biggest emitters of carbon dioxide worldwide.
Canada is the only country to have backed out of the Kyoto Protocol and the United States temporarily left the Paris Climate Agreement under the Trump Administration but re-entered promptly under the Biden Administration.
In 2007, the Nobel Peace Prize was awarded to both Al Gore and the IPCC "for
their efforts to build up and disseminate greater knowledge about
man-made climate change, and to lay the foundations for the measures
that are needed to counteract such change."
Spreading Awareness: A Moral Duty
In a world where mass media is often unreliable, please take note of the important facts on climate change mentioned above.
Nowadays, there is a plethora of disinformation regarding this important issue at hand. Unfortunately, many people have not heard of the real facts on climate change listed in this page.
If we are to find a way to solve the climate crisis, we need to not only collaborate in taking action, but we need to join forces in spreading awareness on mankind's greatest challenge.
Please, take the time to share this crucial information.
Millions of lives and over a million species are a stake. Choosing to make climate change mitigation a number priority is not merely a political choice; rather, it is a moral duty.
