Is the ocean broken?

If photosynthesis slows while respiration increases with temperature, then would there be less plant building processes in tropical rainforests then in temperate forests?
"tropical rain forests are some of the oldest ecosystems on earth, they are home to a diverse population of plants and animals. In fact, around 50% of the world’s plants and animals can be found here—with new species still being discovered."
Rain Forest Rescue https://www.arborday.org/programs/rainforest/animals-and-plants-of-the-rain-forest.cfm
Over 200,000 plant species live in tropical rain forests.

"Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C)"

These studies you list seem to be mostly observation of current phenomenon (perfectly legitimate) put together in speculative projection graphs based on what if this were to increase or that was to be true or one possible explanation is... . I'm not arguing that they are wrong, just that they aren't presenting real and solid evidence that they are right. They can do better.

They are slippery, slithering speculative conjectures. Scaremongering.

 

Are you finding tropical trees like mahogany, rosewood, teak and cocobolo mysteriously growing in your sugarbush?

I think they are saying that the species of trees and other vegetation growing in each particular biome are approaching a critical biological temperature.

In what way do you think they can do better?

 

Yes, but not from me.

 

Oh good. You're the only one who worried me.

 

United Airlines Commits to 100% Green Carbon Neutral by 2050

• United Airlines believes carbon offsets don’t go far enough to address the emissions caused by their operations
  
• They are working towards a sustainable fuel made from renewable resources and waste byproducts, with a smaller carbon footprint of up to 80%
  
• They are making a multimillion-dollar investment in a Direct Air Capture plant to capture, remove and store 1 million metric tons of CO2

How about hydrogen peroxide rocket fuel. That should be carbon neutral.

From Wikipedia: "High-test peroxide (HTP) is a highly concentrated (85 to 98 per cent) solution of hydrogen peroxide, with the remainder consisting predominantly of water. In contact with a catalyst, it decomposes into a high-temperature mixture of steam and oxygen, with no remaining liquid water. It was used as a propellant of HTP rockets and torpedoes, and has been used for high-performance vernier engines."

Sounds exactly like what a safety-conscious industry wants (NOT):

Safety

Since many common substances catalyze peroxide's exothermic decomposition into steam and oxygen, handling of HTP requires special care and equipment. It is noted that the common materials iron and copper are incompatible with peroxide, but the reaction can be delayed for seconds or minutes, depending on the grade of peroxide used.

Small hydrogen peroxide spills are easily dealt with by flooding the area with water. Not only does this cool any reacting peroxide but it also dilutes it thoroughly. Therefore, sites that handle hydrogen peroxide are often equipped with emergency showers, and have hoses and people on safety duty.

Contact with skin causes immediate whitening due to the production of oxygen below the skin. Extensive burns occur unless washed off in seconds. Contact with eyes can cause blindness, and so eye protection is usually used.​

 

The production of H-O-O-H uses energy. No free ride.

 

"Bell Aerosystems began development of a rocket pack which it called the "Bell Rocket Belt" or "man-rocket" for the US Army in the mid 1950s.[1] It was demonstrated in 1961 but 5 gallons of hydrogen peroxide as fuel for 21 seconds of flight time did not impress the army and development was cancelled. This concept was revived in the 1990s and today these packs can provide powerful, manageable thrust. This rocket belt's propulsion works with superheated water vapour. A gas cylinder contains nitrogen gas, and two cylinders containing highly concentrated hydrogen peroxide. The nitrogen presses the hydrogen peroxide onto a catalyst, which decomposes the hydrogen peroxide into a mixture of superheated steam and oxygen with a temperature of about 740 °C. "

Range?

 

The "RB 2000" essentially reimplemented Wendell Moore's design using light alloys (titanium, aluminium) and composite materials. It featured increased fuel stock and increased power, and the maximum duration of flight was increased to 30 seconds.

Carbon Engineering’s Tech Will Suck Carbon From the Sky

Canadian firm Carbon Engineering is designing and building a “direct-air capture” facility in Texas. At its pilot plant in British Columbia, Carbon Engineering combines the pure CO2 with hydrogen to produce synthetic crude oil. The facility can capture 1 metric ton of carbon dioxide per day; by comparison, the Texas operation is expected to capture over 2,700 metric tons daily. At the larger site, the captured gas will be injected into older oil wells, both sequestering the CO2 underground and forcing up any remaining oil.

Zurich-based Climeworks is expanding across Europe. At Climeworks’ pilot site in Iceland—which is powered by geothermal energy—the company’s partner Carbfix reacts the concentrated CO2 with basaltic rock to lock it below ground.

Dublin’s Silicon Kingdom Holdings plans to install its first CO2-breathing “mechanical tree” in Arizona. Each tree will have stacks of 150 disks coated in a carbon-adsorbing material; as wind blows over the disks, they trap carbon on their surfaces. The disks are then lowered into a bottom chamber, where an “energy-efficient process" releases the CO2 from the sorbent

ExxonMobil expanded an agreement with Global Thermostat to help scale the startup’s technology. Global Thermostat’s machines are the size of a shipping container and capture CO2 using amine-based adsorbents on honeycombed ceramic cubes, akin to a car’s catalytic converter.
