Global Climate Highlights 2024 (copernicus.eu)
2024 saw unprecedented global temperatures, following on from the remarkable warmth of 2023. It also became the first year with an average temperature clearly exceeding 1.5°C above the pre-industrial level – a threshold set by the Paris Agreement to significantly reduce the risks and impacts of climate change. Multiple global records were broken, for greenhouse gas levels, and for both air temperature and sea surface temperature, contributing to extreme events, including floods, heatwaves and wildfires.

Fiji is already relocating villages because of climate change (zmescience.com)
Climate migration is no longer a distant fear — it’s a reality. In Fiji, it’s a particularly pressing reality. Rising seas and extreme weather have forced entire communities to move. For this Pacific island nation, the question isn’t whether to relocate people but how to do so in a way that protects lives and livelihoods. Meanwhile, the rest of the world is watching closely as one billion people may find themselves in a similar situation in a matter of decades.

Meltwater from Greenland and the Arctic is weakening ocean circulation (theconversation.com)
A vast network of ocean currents nicknamed the “great global ocean conveyor belt” is slowing down. That’s a problem because this vital system redistributes heat around the world, influencing both temperatures and rainfall.

Humans have caused 1.5 °C of long-term global warming according to new estimates (lancaster.ac.uk)
A new study published today in Nature Geoscience by Dr Andrew Jarvis at Lancaster University and Professor Piers Forster at the University of Leeds shows that humans may have already caused 1.5 °C of global warming when measured from a time genuinely before the industrial revolution and the start of large-scale carbon emissions.

Earth Will Exceed 1.5 Degrees Celsius of Warming This Year (scientificamerican.com)
It is “virtually certain” that 2024 will be the first year to be more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) hotter than in the preindustrial era, before heat-trapping fossil fuels began accumulating in the atmosphere, the European Union’s Copernicus Climate Change Service (C3S) announced today.

Once we pass 1.5°C of global warming, there is no going back (newscientist.com)
It is clear that the world is going to exceed the 1.5°C target for global warming, leading to an increasing focus on plans to cool it down again by removing carbon dioxide from the atmosphere. But there is no guarantee that we will be able to achieve this – and even if we can, some changes can’t be reversed.

Global Catastrophe Looms as Key Ocean Current Nears Collapse, Experts Warn (gizmodo.com)
The collapse of one of the world’s most important ocean currents, a disaster that would wreak havoc on Earth’s ecosystems, is generally considered unlikely. But in a newly issued open letter, leading climate scientists warn that the threat has been underestimated and call for immediate action.

The rate of global sea level rise doubled during the past three decades (nature.com)
Over the past three decades, satellites have provided continuous, accurate measurements of sea level on near-global scales. Here, we show that since satellites began observing sea surface heights in 1993 until the end of 2023, global mean sea level has risen by 111 mm.

Since spring of 2023, the world has been warmer than climate models anticipated (e360.yale.edu)
About 18 months ago, climate scientists began to notice something strange. In March of 2023, global sea surface temperatures started to rise. In a warming world, the seas would be expected to grow hotter, but the rise, which came at a time when the Pacific Ocean was in the neutral phase of the weather pattern known as the El Niño–Southern Oscillation, or ENSO, was unusually steep. In April, 2023, sea surface temperatures set a new record.
