Will humans be extinct by 2026?

1. "In the Arctic, vast amounts of carbon are stored in soils that are now still largely frozen. As temperatures continue to rise and soils thaw, much of this carbon will be converted by microbes into carbon dioxide or methane, adding further greenhouse gases to the atmosphere."

2. "vast amounts of methane are stored in sediments under the Arctic Ocean seafloor, in the form of methane hydrates and free gas. As temperatures rise, these sediments can get destabilized, resulting in eruptions of huge amounts of methane from the seafloor."

3. "Without sea ice, storms can also develop more easily. Storms can mix warm surface waters all the way down to the bottom of shallow seas, reaching cracks in sediments filled with ice. This ice has until now acted as a glue, holding the sediment together."

The soils, waters, sea ice, all work to create the situation so dangerous that huge eruptions can happen at any time. We can feel fortunate that extreme explosions haven't happened yet.

"As temperatures continue to rise, the risk that this will happen keeps growing."

Just a reminder that climate change is non-linear. We tend to forget.

The impact of climate change almost certainly increases with warming and, if we can quantify this impact, probably increases non-linearly. In other words, the impact of 3oC of warming is likely to be more than twice as great as the impact of 1.5oC. [emphasis mine]

What if global warming ends up being greater than we thought?

“Loss of ice in the Chukchi Sea is reinforcing a very wavy jet stream, which might account for the winds and fires in California and cold in the central and eastern U.S. right now,” said oceanographer Jim Overland of the Pacific Marine Environmental Laboratory. 

He explained that the current record low sea ice coverage in the Chukchi Sea off the northwest coast of Alaska has provided a lot more heat to the atmosphere.

A new study shows that ocean heat content is the best way to measure global warming.

Ocean temperature as a vital sign revealing Earth's warming

This study shows that the temporal evolution of ocean heat content has a relatively high signal-to-noise ratio; therefore, it requires 3.9 years to separate the global warming trend from natural variability. Similarly, for sea level rise, 4.6 years are sufficient to detect the climate change signal. By contrast, owing to weather, the El Niño-Southern Oscillation and other natural variability phenomena embedded in the global mean surface temperature record, scientists need at least 27 years of data to detect a robust trend. 

The black line is ocean heat content, the pink is CO2 level, blue is CO2 measured at Mauna Loa.

Ruth, is there any notification of sea rise?

Temperature anomaly map for northern hemisphere clearly shows heat from climate destabilization, and two cool spots from Greenland's meltwater.

The entire Amazon is threatened by deforestation on the fringes.

“Our study shows that the ongoing deforestation of the Amazon outskirts may have a negative impact on the entire rainforest”, says Minchao Wu.

The explanation is that deforestation affects the climate both locally and regionally, creating a vicious circle. When the trees disappear from the outskirts of the forest, it creates significant local warming. Furthermore, it changes the air circulation patterns throughout the Amazon area during the dry season.

This chain of events is self-perpetuating and creates a vicious circle with an increasingly higher risk of disrupting the balance of the entire ecosystem. The untouched inner parts of the Amazon rainforest are thus also at risk of adverse effects, even though the actual felling of trees takes place far away in the outermost areas.

“Our results indicate that this has already started to happen in the Amazon rainforest. [emphasis mine]

Deforestation in Amazon basin could disrupt the distant rainforest ...
