James Hansen Wishes he Wasn’t So Right about Global Warming

New study warns climate is warming even faster than some think​

Global ocean heat content anomaly​

Relative to 1981-2010 mean; Annually, 1940-2022
A purple and orange bar chart showing the global ocean heat content anomaly, relative to the 1981-2010 mean. Global ocean heat content is rapidly growing, reaching almost 250 zettajoules above the 1981-2010 mean in 2022.


Data: Cheng, et al., 2023, "Another year of record heat for the oceans"; Note: For the upper 2,000 meters of ocean; Chart: Axios Visuals
A new study warns the Earth's climate is on track to warm significantly more than shown by the U.N. Intergovernmental Panel on Climate Change's (IPCC) projections.
Driving the news: The paper, published Thursday in the peer-reviewed journal Oxford Open Climate Change, is a synthesis of new and previous discoveries across multiple fields. It is peppered with policy prescriptions, unusual for a scientific paper.

• The stark warning comes from ex-NASA scientist James Hansen, who is the lead author of the report. In 1988, he famously and accurately warned that human-caused warming would soon emerge from the background noise of natural variability.

Why it matters: Should the paper's authors be proven correct this time, the globe can expect more severe extreme weather events, species losses and sea level rise than currently projected.

• The paper lands as the planet endures its warmest year on record, with sizzling new benchmarks set on land and sea. Each month since May has set consecutive new milestones.

Yes, but: Hansen has long straddled the line between scientist and activist. In the new paper, he recommends pursuing a range of policy options, from putting a price on carbon to geoengineering.

• In this study, he calls on climate scientists to embrace the responsibilities medical professionals have to their patients. He argues they have been too reticent and conservative to lay out the full ramifications of warming.
• "We are in the early phase of a climate emergency," Hansen writes.

That's a lot of warming!!!!

How many new nuclear reactors should we build?

 

[westwall]

That's a lot of warming!!!!

How many new nuclear reactors should we build?

How many times have they made that claim now?

 

[Toddsterpatriot]

How many times have they made that claim now?

Too many.
I don't even care about their stupid claims, I'm much more concerned about their stupid fixes.

Did they explain how the atmosphere which is 1/300th the mass of the ocean, contains 1/1000th the heat of the ocean and has only increased by 1.5C over 100 years caused this?

Cause someone needs to tell them that's the sun, dummies.

The oceans are the temperature regulators of the atmosphere and thus the earth.

Lots, if we are smart. In fact, we could use this an indicator of human intelligence.

And what warms the Ocean?
You seem to be very confused about Cause and effect.
While the relationship between our GHG emissions and Temperature is well established.
In fact there's 'more ocean' (in heat expanded volume and melt) and more water vapor due to AGW-trapped heat.
Your 'Ocean' theory/god doesn't preclude AGW as the Cause.. and then you have to go to your religion section shlt.

And what warms the Ocean?`

The sun, dumbass, the sun.

The ocean is the largest solar energy collector on Earth. Not only does water cover more than 70 percent of our planet’s surface, it can also absorb large amounts of heat without a large increase in temperature. This tremendous ability to store and release heat over long periods of time gives the ocean a central role in stabilizing Earth’s climate system. The main source of ocean heat is sunlight. Additionally, clouds, water vapor, and greenhouse gases emit heat that they have absorbed, and some of that heat energy enters the ocean. Waves, tides, and currents constantly mix the ocean, moving heat from warmer to cooler latitudes and to deeper levels.

Heat absorbed by the ocean is moved from one place to another, but it doesn’t disappear. The heat energy eventually re-enters the rest of the Earth system by melting ice shelves, evaporating water, or directly reheating the atmosphere. Thus, heat energy in the ocean can warm the planet for decades after it was absorbed. If the ocean absorbs more heat than it releases over a given time span, its heat content increases. Knowing how much heat energy the ocean absorbs and releases is essential for understanding and modeling global climate.

Climate Change: Ocean Heat Content​

 

[ding]

You seem to be very confused about Cause and effect.

Not at all. The sun warms the planet unevenly. This produces weather; wind circulation patterns and ocean circulation patterns which is influenced by landmass distribution.

For any given landmass configuration there will be a resulting climate. The only constant is the sun warming the planet surfaces (land and water) unevenly at all times (i.e. the distance to the sun is not the same for all points on the planet). As wind and ocean circulation changes so does the climate at different locations. Some locations are more sensitive to these changes (i.e. the Arctic) and will have a greater impact on global climate.

So now you back to REFUTING YOURSELF about the Milanki cycles as being the cause!
You're been saying the opposite for months you IDIOT!
BTW, he Sun output has been measured directly for more than 50 years.
It has not increased, yet the Ocean, Air and land temps have.
Welcome to AGW.

What has changed is GHG Trapped heat in direct contact with the ocean surface .. as well as warmer water coming off the land every time it rains anywhere on land or thru the warmer air.
Ooops.

Your STUPID Ocean-as-the-heat-source/caused /God as the driver makes no sense and doesn't work now or historically.

While the relationship between our GHG emissions and Temperature is well established.

Actually it's not. What is well established is how the ocean absorbs and releases CO2 as a function of temperature.

The GHG effect of CO2 is 1C per doubling of CO2. That is well established. The nonsense they are peddling of 3.5C to 4.5C is ridiculous and unsupported by any direct or indirect evidence. It's an artifact of flawed modeling.

 

[ding]

In fact there's 'more ocean' (in heat expanded volume and melt) and more water vapor due to AGW-trapped heat.

Not to the extent they are claiming. It's effectively negligible. It's the sun and how the ocean distributes that heat that is creating warmer temperatures and more water vapor. And that is why they are overestimating the GHG effect of CO2. They should stick to the theoretical calculations using simple physics. 1C per doubling of CO2.

But if they did that they couldn't hop up and down like monkeys screeching ooooh, oooh, ooh!

 

[ding]

First of all it's not my theory. Plenty of papers on the ocean's role in the planet's climate. Secondly, it absolutely does preclude the catastrophic projections of AGW. The theoretical GHG effect of CO2 from simple physics is 1C per doubling of CO2.

But now you say the Sun is the cause Refuting what you said yesterday and previous. when I/others brought up the Milanki factor warming cooling, NOT the Ocean itself.
The Sun also warms the land and air... as does the GHG TRAPPED Heat surrounding the whole planet
You, as usual have a mental block.
You're Sick and need treatment for your logical blackouts and posting frequency/obsession.

Lying, it's what you do.....

Yes, I use to believe orbital cycles played a larger role in the planet's climate. But I now believe their only affect is in affecting wind patterns.

 

[CrusaderFrank]

On average, each year the temperature increases by 50 to 60F for 6 months, then decreases by 50 to 60F. Why would a 1F change over 150 years made a difference, even if it weren't an accounting fiction?

abu afak can you explain how every living thing survives 50 to 60 degrees swing biannually, but 1 degree over 150 years will end all life on Earth?
