The Guardian surveyed the world's top climate scientists and found hundreds believe that the global temperature will reach 2.5 Celsius creating disastrous conditions for humanity. Many expressed feeling hopeless as government officials are not acting despite clear scientific evidence.

Oceans' record heat streak reaches 13 months

... April's global average sea surface temperatures have checked in as the warmest on the books, per the Copernicus Climate Change Service, meaning the ocean's surface has notched 13 straight months of record heat.
The big picture: For years, the world's water bodies have been warming in deeper depths and at the surface, but the ongoing streak is breaking previous milestones. ...
@#7 ... Thanks crypto-miners! ...

When did scientists first warn humanity about climate change? (2021)
www.livescience.com
... Scientists first began to worry about climate change toward the end of the 1950s, Spencer Weart, a historian and retired director of the Center for History of Physics at the American Institute of Physics in College Park, Maryland, told Live Science in an email. "It was just a possibility for the 21st century which seemed very far away, but seen as a danger that should be prepared for."
The scientific community began to unite for action on climate change in the 1980s, and the warnings have only escalated since. However, these recent warnings are just the tip of the melting iceberg; people's interest in how our activities affect the climate actually dates back thousands of years. ...
So, maybe any "thanks" should go to the GOP for denying to do anything about it since, well, always?
All that aside, the oceans are the warmest they've been in a long time.
@#11 ... Has it not already done that? ...
Climate change: The 1.5C threshold explained (February 2024)
www.bbc.com
... But have we not passed the 1.5C threshold already?
The year 2023 is on track to be the hottest on record. It brought the world's hottest July in 120,000 years, and September was also the hottest on record by a large margin.
The global average daily temperature was more than 1.5C more than the preindustrial average for roughly one-third of days in 2023. Needless to say, this was a record number of days above the 1.5C daily limit.
But there is a big difference between the global temperature on individual days, and the long-term average. The latter is what's meant when the 1.5C threshold is discussed in negotiations like COP28 -- 1.5C warming is an average figure over a decadal time scale. This is a hard thing to measure, says Allen, and we know the global decade-to-decade average to within about a tenth of a degree at best.
Just as if you look at individual days rather than long-term averages, if you zoom in on particular regions of the world, we can also see that the 1.5C is being breached on local and regional levels.
The Arctic has warmed nearly four times faster than the rest of the world since 1979. Africa, too, warmed by around 0.3C per decade between 1991 and 2020, faster than the global average and faster than the 0.2C per decade in the 30 years before that.
When might we pass 1.5C on our current track and how will we know?
Earlier in 2023, the IPCC calculated that by the mid-2030s there would be a 50% chance of the world commiting itself to a rise of 1.5C. However, a new analysis taking into account more recent data suggests we could reach this threshold sooner " as early as 2029. ...
