*Nitrous oxide (N2O), a 300 times more porent GHG gas than carbon dioxide, which is responsible for roughly 6-7% of total GHG emissions, is currently being emitted at the worst-case-scenario rate, mostly from agricultural soil management (78% in the US), like the usage of fertilizers

*New earth system model shows self-sustained melting of permafrost even if all man-made GHG emissions stip in 2020

www.nature.com/articles/s41598-020-75481-z

*Thawing permafrost (which makes 24% of the Earth's land surface) is releasing microorganisms, with consequences that are still largely unknown (some microbres are entirely unfamiliar to scientists), as scientist warn that the poles are warming 4 times faster than the rest of the globe. In 2016 perfamrost thaw caused an anthrax outbreak killing 200,000 deers and a child.

www.scientificamerican.com/article/deep-frozen-arctic-microbes-are-waking-up

*Based on the CMIP6 (latest generation of climate models), 'Carbon Brief''s analysis shows that the world will likely exceed 1.5C degrees around 2031 if emissions are not rapidly reduced, and 2C degrees around 2043. In a scenario of modern mitigration, the 2C degrees threshold would be exceeded around 2052.

*Newly identified jet-stream pattern could imperial global food supplies: "They can cause 4% reduction in crop production in affected important region for global food production, with regional decrease up to 11%".

A "Food System Shock" report from 2015 by an insurance giant outlines a plausible extreme shock to global food production involving multiple droughts that could cause rioting, terrorist attacks, civil war, mass starvation and severe losses to the global economy - with odds of this occurring higher than 0.5% per year, or 18% that it'll happen in the next 40 years.

https://blogs.scientificamerican.com/eye-of-the-storm/newly-identified-jet-stream-pattern-could-imperil-global-food-supplies

*Dr. Andrew Glikson says "net zero emissions by 2050" is not enough to slow down global warming, as it overlooks ongoing investments in fossil fuels and accelerated rise of temperarture from land and ocean feedback effects.

https://arctic-news.blogspot.com/2020/12/the-myth-of-net-zero-emissions-by-2050.html

*Temperartures could rise more than previously estimated, up to an 18 degrees rise, if taking into account seafloor methane release, cloud feedback, growing intensity of forest fires, loss of cooling of aerosols and Arctic feedback loops.

It's estimated that at a 3 degrees rise, humans could become extinct, and at a 5 degrees rise most life on earth will disappear, and if the trend continues [a 2019 analysis warns that] Earth could go the same way as Venus.

https://arctic-news.blogspot.com/2020/12/temperatures-keep-rising.html

*New study suggests previous estimations of pre-industrial revolutions temperartures did not take into account some changes in sea surface and ice, resulting in a bigger change in temperartures in comparison with today - 2.3 degrees warmer than then, instead of 1.4 as was previously accepted [January 20201]

www.ecowatch.com/greenhouse-gases-paris-agreement-2649767807.html

*New study suggests that sooner than expected, trees could become carbon sources rather than carbon sinks, as a feedback loop drives them to realse more GHG gases.

The study also claims that 50% of the terrestrial bioshpere (soil and vegetation) could reach temperatures that limit photosynthesis by mid-century, with the most carbon-rich ecosystems reaching the tipping point first (like the Amazon and South-East Asia)

https://insideclimatenews.org/news/13012021/forests-heat-climate-change/

*The planet is dying faster than we thought: A new study says that if current agriculture trend continues, as many as 1 million of Earth's 7 to 10 million planet and animal species could face extinction in the near future, distrupting every major ecosystem on the planet. Natural disasters are predicted to become stronger and more frequent, resulting in 1 billion climate refugees by 2050. Overpopulation will exacerbate numerous societal problems. Delay between cause and effect means that the worst outcome could decades to become apparent. We are currently past meeting the Paris Agreement goals, heading towards a 4.1 degrees temperarture rise - slightly more than halfway towards the UN's worst-case scenario.

*Climate change risks pushing one-third of global food production outside the same climate space. Following the Paris Agreement would reduce this risk considerably (low emission scenario: 8% food crop, 5% livestock, high emission scenario: 31% food crop, 34% livestock) by 2081-2100.

https://au.news.yahoo.com/scientists-warn-australia-catastrophic-risk-humanity-053429390.html

*An new risk analysis examined the interaction between Antarctica and Greenland's ice sheets and the Amazon Rainforest, found that Ice sheets and ocean currents at risk of climate tipping points can destabilise each other as the world heats up, leading to a domino effect with severe consequences for humanity.

The scientists carried out 3m computer simulations and found domino effects in a third of them, even when temperature rises were below 2C, the upper limit of the Paris agreement.

The ocean currents of the Atlantic Meridional Overturning Circulation (AMOC), of which the Gulf Stream is an important part and keeps western Europe mild, are at their weakest in more than a millennium.

*The nine boundaries humanity must respect to keep the planet habitable:

Climate change, biodiversity loss, ocean acidification, ozone depletion, atmospheric aerosol pollution, freshwater use, biochemical flows of nitrogen and phosphorus, land-system change, and release of novel chemicals.

"If we are to steer our planet away from a devastating new trajectory, phasing out fossil fuels to reach a net-zero greenhouse gas emissions world economy is a key priority.

But even more pressing, experts say, is a change to our food systems, as food production is the biggest driver of biodiversity loss, the primary cause of land-use change, one of the largest sources of nitrogen and phosphorus pollution, it generates huge freshwater demand, and as it generates big carbon emissions, it also adds to the ocean acidifaction. That covers six of the nine planetary boundaries."

*Draft UN report, by far the most comprehensive catalogue ever assembled of how climate change is upending our world: crushing climate impacts to hit sooner than feared.

Climate change will fundamentally reshape life on Earth in the coming decades, even if humans can tame planet-warming greenhouse gas emissions.

Species extinction, more widespread disease, unliveable heat, ecosystem collapse, cities menaced by rising seas—these and other devastating climate impacts are accelerating and bound to become painfully obvious before a child born today turns 30. 

The choices societies make now will determine whether our species thrives or simply survives as the 21st century unfolds

"Life on Earth can recover from a drastic climate shift by evolving into new species and creating new ecosystems," it says.

"Humans cannot."

"We need transformational change operating on processes and behaviours at all levels: individual, communities, business, institutions and governments," it says.

"We must redefine our way of life and consumption."

*16 out of 31 tracked planetary vital signs, including greenhouse gas concentrations, ocean heat content and ice mass, set worrying new records, according to a new study.

“There is growing evidence we are getting close to or have already gone beyond tipping points associated with important parts of the Earth system”

“Policies to alleviate the climate crisis or any of the other threatened planetary boundary transgressions should not be focused on symptom relief but on addressing their root cause: the overexploitation of the Earth."

www.theguardian.com/environment/2021/jul/27/global-heating-critical-measures-tipping-point-study

*The Atlantic meridional overturning circulation (AMOC) is already at its slowest point in at least 1,600 years, but a new analysis shows it may be nearing a shutdown. The complexity of the AMOC system nd uncertainty over levels of future global heating make it impossible to forecast the date of any collapse for now, but such an event would have catastrophic consequences around the world, severely disrupting the rains that billions of people depend on for food in India, South America and West Africa; increasing storms and lowering temperatures in Europe; and pushing up the sea level in t4he eastern North America. It would also further endanger the Amazon rainforest and Antarctic ice sheets.

*Leaked UN report says emissions must peak within 4 years [by 2025], coal and gas-powered plants must close in the next decade and lifestyle behavioral changes will be needed to avoid climate breakdown.

The report underlines the lifestyle changes that will be necessary, particularly in rich countries and among the wealthy globally. Refraining from over-heating or over-cooling homes, walking and cycling, cutting air travel and using energy-consuming appliances less can all contribute significantly to the reductions in emissions needed, the report finds.

Plant-based diets can reduce emissions by up to 50% compared to the average emission intensive western diet.

The publication that leaked the draft said it showed that the global economy must be shifted rapidly away from a reliance on conventional GDP growth, but that the report underplays this.

*-"If emissions follow the trajectory set by current NDCs, there is less than 1 per cent chance of reaching the 1.5°C target set by the 2015 Paris Agreement."

-If policy ambition, low-carbon technology deployment and investment follow current trends, 2.7°C of warming by the end of this century is likely, relative to pre-industrial temperatures. A plausible worst case of 3.5°C is possible (10 per cent chance). These projections assume Paris Agreement signatories meet their NDCs. If they fail to do so, the probability of extreme temperature increases is non-negligible.

-Any relapse or stasis in emissions reduction policies could lead to a plausible worst case of 7°C of warming by the end of the century (10 per cent chance).

*New research says record-shattering heatwaves are becoming much more likely, worse than those seen in North-West American in June 2021. Highl opulated regions in North America, Europe and China were where the record-shattering extremes are most likely to occur. One heatwave scenario showed some locations in mid-northern America having temperatures 18C higher than average.

It found that heatwaves that smash previous records by roughly 5C would become two to seven times more likely in the next three decades and three to 21 times more likely from 2051–2080, unless carbon emissions are immediately slashed. Such extreme heatwaves are all but impossible without global heating.

The study showed that if emissions start falling immediately and rapidly, the risk of record-shattering extremes is cut by about 80%

*It is generally believed that anthropogenic aerosols cool the atmosphere and offset global warming from greenhouse gases to some extent. This study shows that a reduction in the aerosol SO2 will enhance atmospheric warming, in comparison with present CO2 concentrations, by about 0.5C degrees (in the high latitudes of the Northern Hemisphere).

*Deep ocean methane, usually stable at very specific pressure and temperatures at the Arctic, is likely to be released again to surface water and to the atmosphere, due to melting ice (the ice sheets create pressure that stabilizes the seafloor, which now decreases with the ice melting)

https://phys.org/news/2021-03-arctic-methane-due-ice.html

*The ocean, which makes a carbon sink that offsets the atmosphere warming, could absorb less CO2 as we emit less of it into the atmosphere

*According to Dr. Malcolm Light, the greatest threat to humanity is the escalating Arctic atmospheric methane buildup, caused by the destabilization of subsea methane hydrates. This subsea Arctic methane hydrate destabilization will go out of control in 2024 and lead to a catastrophic heatwave by 2026, by release more than 50 giga tonnes of methane [and precipitate a terminal catastrophic global extinction by the summer of 2027].

The total subsea methane reserves are much greater than the 1400 giga tonnes on the East Siberian Arctic shelf, holding huge amounts of methane that can be released at any moment.

https://arctic-news.blogspot.com/2021/05/extinction-by-2027.html

*New study in Global Biogeochemical Cycles shows per-area GHG emissions from the world's water resrevoirs are around 29% higher than suggested by previous studies.

Much of the increase comes from methane degassing (where methane passes through a dam and bubbles up downstream), which is estmated to occur mostly in tropical climate zones (83%).

Overall, researchers found the world's water reservoirs produce GHG at about 1.07 gigatons of CO2e (compared to more than 36 gigatons of annual man-made GHG emissions). That's more than 2% of the man-made emissions!

*IPCC's sixth assessment suggests methane accounts for 30-50% of current rise in temperartures, about 0.5 degrees!

About 40% of methane emissions come from natural sources such as wetlands, while the rest comes from a variety of sources from human activity, from fossil fuel extraction leaks, to cattle raising, growing rice and garbage management.

Cutting 40-45% of methane by 2030 will shave off 0.3 degrees of temperarture increase by 2040

*Record-breaking Intense blazes, including fires in hotspots in the Mediterranean, North America and Siberia, let off more than 2.7 billion metric tons of carbon over the summer, with July and August both breaking monthly records for emissions from fires. More than half of July's emissions could be put down to fires in North America and Siberia.

https://edition.cnn.com/2021/09/21/world/wildfire-northern-hemisphere-intl-scli/index.html

*Wildfires emit about 8 million tons of CO2 per year, with 106.7 million tons emitted in 2020.

Scientists estimate that wildfires emit up to 5-10% of annual global CO2 emissions yearly.

https://news.ncsu.edu/2021/12/time-lag-could-still-lead-to-climate-tipping-point

*Earth system models project that climate change will lead to a gradual weakening of the ocean carbon uptake rate, but most models do not incorporate the impact of warming and reduced nutrient supply on carbon & nutrient recycling and biodiversity. If these aspects are considered, the there is an even greater weakening of the ocean’s capacity to act as a carbon sink in the future

*Study estimates 85% of methane growth since 2007 came from microbes (such as natural wetlands ro human-raised livestock and landfills), with fossil fuel extraction accounting for the remainer. Antrhopogenic sources were estimated to account for about 62% of total methane emissions from 2007 to 2016 (161.6m tons/year from wetlands, 129.5 from fossil fuel extraction, 103 from livestock, 72.9 landfill and agricultural waste, 37.5 natural geological seeps, 34.2 rice cultivation, 27.7 burning of plant matter and 24.2 from termites and other wild animals).

*Changes in human settlement patterns and agriculture have led to less burning in grasslands, tropical forests and savannahs: Between 1998-2015, the total global acreage burned by fires declined by 24%.

[Fewer and smaller fires on the savanna mean that there are more trees and shrubs instead of open grasslands. This is a significant change in habitat for the region’s iconic mammals like elephants, rhinoceroses, and lions. Regions with less fire saw a decrease in carbon monoxide emissions and an improvement in air quality during fire season. With less fire, savanna vegetation is increasing—taking up more carbon dioxide from the atmosphere.]

*Combining five types of broad fixes to the food system will give the best chances to fight climate change:

 - Switching to an almost complete plant-based diet (650 billion metric tonnes GHG reduction),

 - Almost everyone eating the right amount of calories for them (410),

 - Using less fertilizers, better managing of soil and crop rotation (540),

 - Increasing yield through genetics and other methods (210),

 - Wasting less food (360),

 And, doing just half of all of these will reduce GHG emissions by 850 billion metric tonnes.

*"There aren't enough trees to offset society's carbon emissions - and there never will be. If we absolutely maximised the amount of vegetation all land on Earth could hold, we'd sequester enough carbon to offset about ten years of greenhouse gas emissions at current rates. After that, there could be no further increase in carbon capture."

Natural forests also store more carbon than plantation forests, due to complex stand structures and accumulation of belowground and in the forest floor. Features that take centuries to emerge.

Researches are in unanimous agreement that land ecosystems have a finite capacity to take up carbon. And, fundamental misunderstandings about carbon capture by land ecosystems can have devastating consequences, paradoxically resulting in loss of biodiversity and an increase in atmospheric CO2 concentrations.

*Climate stresses on forests, such as heat, drought, fires, pests and pathogens, are increasing a lot faster than expected. New research suggests that droughts, rather than the amount of CO2 in the air and photosynthesis, may have the biggest impact on how quickly trees grow in the future. Lowering GHG emissions could have a huge impact for avoiding damage to forests form wildfires, drought and insects.

Together, the two studies suggest that the benefits of CO2 for tree growth won't be nearly as large as people thought, which has huge implications on using forests as carbon offsets.

*Rate of ice loss is now in line with the IPCC's worst case scenario, as about 28 trillion tonnes of ice between 1994-2017 (equivalent to about 35 millimetres of sea leve rise), which is enough to cover the entire UK with an ice sheet 100 metres thick. The greatest quantities were lost in the Arctic sea, raising the risk of a feedback mechanism known as albedo loss.

*Evidence of Pine Island Glacier (which is two thirds the size of England) in Western Antarctica's tipping point is confirmed in a new research - with ocean temperartures reaching 1.2 degrees celsius.

The Western Antarctica Ice Sheet contains enough ice to raise sea level by over three metres.

"Should the glacier enter unstable irreversable retreat, the impact on sea level could be measured in metres, and as this study shows, once the retreat starts it might be impossible to halt it".

*Water explusion mechanism in the West Anarctica ice sheet could raise sea levels by up to 30% more than previously thought. This means an extra meter added to the sea-level rise predictions of the next 1,000 years: 4 meters rise instead of 3.2.

The global rate of species extinction today is higher than the average rate over the past 10 million years.

A reform of food systems is a matter of urgency and should focus on three interdependant actions:

*Global dietary patterns need to move towards more plant-heavy diets

*More land needs to be protected and set aside for nature

*We need to farm in a more nature-friendly, biodiversity-supporting way, limiting the use of inputs and replacing monoculture with polyculture farming practices

*The desert's fragile "living skin" (the biocrust, which covers 12% of the planet's surface), home to fungi, lichen and bacteria that protect the deserts from erosion like a glue that holds the soil together, is being destroyed by climate change and human activity. The biocrust could be nearing a tipping point, as it has an upper heat limit, that we don't fully understand yet. Without it, there will be no soil, as it will have been blown by winds into rivers and our lungs. The biocrust prevents the horrible dust storms and bowls like we saw in the 1930s, absorbs water, provides stability for plant growth, increases soil fertility, aids in carbon storage, reduces mudslides and impacts the hydrological cycle in the region, protects municipal groundwater sources, and prevents dust from lowering the albedo of nearby glaciers

*Opinion: Carbon pricing is not sufficient to mitigate climate change, as it has five central weaknesses:

1) problem framing and solution orientation, 2) policy priorities, 3) innovation approach, 4) contextual considerations, and 5) politics.

Suggested instead is 'Sustainability transition policy' that tackles climate change as a system problem, instead of a market failure.

*Covid-18 led to a 7% drop in carbon dioxide emissions, the biggest ever, caused mostly by reduction in the transportation section, with aviation and road transport falling by almost a half at peak times.

While pandemic lockdowns are a temporary respite, according to the UN the world needs to continue a 7.6% yearly reduction in CO2 emissions by 2030, to reach the more ambitious temperature limit of 1.5 degrees celsius, above pre-industrial-revolution temperatures.

Greenhouse Gas Emissions by Sector pie by The Environmental Artist

The purpose of this pie is to give an idea on which industries contribute most to climate change.

It is important to remember that the numbers shown here are not 100% accurate, as often times different sectors overlap in their influence, and therefore the pie surpasses 100%.
