I speak about climate futures, mitigation and adaptation in the face of the climate crisis. 🇿🇦

This from Shell in 1989.

Shell was given an opportunity to respond to the reporting on this and did not deny the legitimacy of the document See https://www.desmog.com/2023/03/31/lost-decade-how-shell-downplayed-early-warnings-over-climate-change/

And from the researcher who found the documents https://changerism.com/portfolio/dirty-pearls-exposing-shells-hidden-legacy-of-climate-change-accountability-1970-1990/

A classic tale of profits before people and planet. This one is particularly egregious as it effects everyone everywhere.

Here is a great graphic to show you the instruments we rely on to track the changes the planet is undergoing as it continues to heat.

A lot of the data from these instruments is getting close to real-time, which is incredibly important for early warning systems.

Great to see your interest in the topic. It’s an important one!

1) Climate models are mathematical simulations of the physical and chemical processes that affect Earth’s climate, such as the atmosphere, ocean, ice, land surface and the Sun. They are not perfect, but they are based on solid physics and rigorous analysis of observations. They are tested by comparing their projections with real-world historical records, and they are given a score of how well they match reality. A study published in 2020 found that most of the climate models developed between 1970 and 2007 were quite accurate in projecting global average temperature changes. (See https://www.nationalgeographic.com/environment/article/how-climate-models-got-so-accurate-they-earned-a-nobel-prize) Another study published this year found that even Exxon’s climate projections from the 1980s were skilled and consistent with modern models. (See https://www.science.org/doi/10.1126/science.abk0063#core-R38) Of course, there is always uncertainty and variability in climate projections, and some models may perform better than others in different regions or time periods. But overall, the models have been proven to be reliable tools for understanding how global warming works and what its impacts might be.

2) Human flourishing does not necessarily require the use of more fossil fuels and coal. In fact, relying on these sources of energy can and do have negative consequences for human health, security, economy and environment. There are many alternatives to fossil fuels that can provide clean, affordable and sustainable energy for human development, such as solar, wind, hydro, geothermal, nuclear and bioenergy. Many countries and regions have already made significant progress in transitioning to low-carbon energy systems, and there are many benefits to doing so, such as reducing greenhouse gas emissions, improving air quality, creating jobs, enhancing energy security and saving money. My concern over global temperatures is not just observational, but also based on the scientific evidence that shows that human-caused climate change is a serious threat to humanity and the planet. The more we can reduce our emissions and limit the warming, the more we can avoid the worst impacts of climate change, such as extreme weather events, sea level rise, biodiversity loss, food insecurity, water scarcity, conflict and displacement.

Hope that helps!

Yeah so the records that are currently being broken in Spain are happening against a backdrop of overall warming of 1.8°C pre industrial.

This background warming is what is causing the records to fall.

The same goes for all the areas mentioned and more.

The difference between weather and climate is a measure of time.

Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere "behaves" over relatively long periods of time.

This is referring to an “new normal” where these events repeat with ever increasing regularity.

A large area wet bulb event, a large area water scarcity event, multiple food basket failures etc.

We are creeping ever closer to a major climate shock. Record temps I’m March for large parts of India, Japan & China and now in Europe. 😳

The polar regions are some of the closest observed parts of the planet one reason being their direct impact on sea level rise. There is so much equipment trained on these areas it's insane.

This paper on very important research concluded in the Antarctic was just released "Antarctic Overturning Slowdown — Melting ice set to transform our oceans"

"This pattern of bottom water warming is already apparent in observations of change in the ocean's abyssal layers, as estimated by [Sarah Purkey] and [Dr Gregory C. Johnson] , although OBS are outpacing our model projections. So we are likely already 'mid slowdown' today."—Prof Matt England

This has massive implications for the food chain sea life above depends on and also the speed of ice melting that is already taking place.

Here is Prof Matt England's (one of the research authors) high level summary of the data:

We are completely unprepared.

“We find that #India could become one of the first places in the world to experience heat waves that cross the survivability limit for a healthy human being sitting in the shade. Without targeted adaptation action, around 160-200 million people in India could annually bear a 5 percent chance of being exposed to a lethal heat wave as early as 2030, a ~40% cumulative likelihood over the decade centered on 2030.” — https://www.mckinsey.com/~/media/mckinsey/business%20functions/sustainability/our%20insights/will%20india%20get%20too%20hot%20to%20work/will-india-get%20too-hot-to-work-vf.pdf

The instruments we use to track the changes happening to our physical world as we continue to heat are becoming more accurate. (ie satellites, floats, tidal stations, weather stations etc.)

As a result our risk projections are getting smarter which is why we can now say with high confidence that approximately 3.3 to 3.6 billion people live in contexts that are highly vulnerable to climate change.

That’s really weird it link opens on my side 🤔 - maybe try access the post from the Japan Times main page.
