Uh… those are all suggestions about what we need to do more of. They’re not saying “this is fine because we’re doing these things.” They’re saying “this will be fine if we take action like Antonio has been begging you to do for years.”
> TS.D.4.5 Ecosystem-based adaptation measures can reduce climatic risks to people, including from flood, drought, fire and overheating (high confidence). Ecosystem-based adaptation approaches are increasingly being used as part of strategies to manage flood risk, at the coast in the face of rising sea levels and inland in the context of more extreme rainfall events (high confidence). Flood-risk measures that work with nature by allowing flooding within coastal and wetland ecosystems and support sediment accretion can reduce costs and bring substantial co-benefits to ecosystems, liveability and livelihoods (high confidence). In urban areas, trees and natural areas can lower temperatures by providing shade and cooling from evapotranspiration (high confidence). Restoration of ecosystems in catchments can also support water supplies during periods of variable rainfall and maintain water quality and, combined with inclusive water regimes that overcome social inequalities, provide disaster risk reduction and sustainable development (high confidence). Restoring natural vegetation cover and wildfire regimes can reduce risks to people from catastrophic fires. Restoration of wetlands could support livelihoods and help sequester carbon (medium confidence), provided they are allowed accommodation space. Ecosystem-based adaptation approaches can be cost effective and provide a wide range of additional co-benefits in terms of ecosystem services and biodiversity protection and enhancement.

There are signs of looming local catastrophes, that can be mitigated if we do enough. We should be talking about saving those people, that would be a positive twist. A saving mission, what can be more noble and relatable to westerners?
Instead Antonio uses fear. And I agree with one grandma that recently said on TV in relation to republicans banning books: "Fear is not future. Fear is control"
And Antonio using fear is not begging, Antonio is manipulating for control.

They tried the saving mission, and most countries ignored the recommendations at any meaningful scale. You want a positive outcome? Stop making excuses about the source of the messaging and start doing what the scientists recommend instead of claiming we’re already on a positive trajectory.
Edit: it bugged me so I had to address it. 10-20% of global GDP and millions of people is no longer “local.” Moreover, the catastrophes are not “looming,” they’re already happening as articulated by the scientists in your own source.

This BS probably works for you with younger dudes, but I've been in thinking capacity since the time it was called 'global warming', and it has always been about "everybody dies unless we stop fossil in ___ years".
>start doing what the scientists recommend
As far as I'm concerned we're already doing it. And we're already on positive trajectory as compared to those RCP scenarios that were extensively used in 90s and 2000s as mainstream scenarios.

Global warming and climate change refer to different things.
By the way, not everybody dies, just far more people than need to. They literally catalogue how many they anticipate in the source you provided.
> TS.C.6.3 Increased heat-related mortality and morbidity are projected globally (very high confidence). Globally, temperature- related mortality is projected to increase under RCP4.5 to RCP8.5, even with adaptation (very high confidence). Tens of thousands of additional deaths are projected under moderate and high global warming scenarios, particularly in north, west and central Africa, with up to year-round exceedance of deadly heat thresholds by 2100 (RCP8.5) (high agreement, robust evidence). In Melbourne, Sydney and Brisbane, urban heat-related excess deaths are projected to increase by about 300 yr-1 (low emission pathway) to 600 yr-1 (high emission pathway) during 2031–2080 relative to 142yr-1 during 1971–2020 (high confidence). In Europe the number of people at high risk of mortality will triple at 3°C compared to 1.5°C warming, in particular in central and southern Europe and urban areas (high confidence). {6.2.2, 7.3.1, 8.4.5, 9.10.2, Figure 9.32, Figure 9.35, 10.4.7, Figure 10.11, 11.3.6, 11.3.6, Table 11.14, 12.3.4, 12.3.8, Figure 12.6, 13.7.1, Figure 13.23, 14.5.6, 15.3.4, 16.5.2}
See what I mean?

Here's the CO^2 trendline. Where's the dip we'd see if we were doing this action?
Oh, and the 90s and 2000s mainstream scenarios? Here are some examples:

When that was published in 1989, we were at 0.27C increase. When the Kyoto Protocol was signed 8 years later in 1997, it was 0.33C.
> "I am a fundamentally optimistic person, but it is getting more and more difficult, because I see the message of science has not fundamentally changed from when I started working in this field, which was 20 years ago," said Thomas Stocker, a professor of climate and environmental physics at the University of Bern in Switzerland.
> Based on two assumptions — that it is not economically feasible for nations to make emissions reductions of more than about 5 percent per year and that increasing carbon dioxide concentrations have a moderate warming effect — he calculates a 2.7 degree Fahrenheit (1.5 degree Celsius) cap on warming, for which island nations vulnerable to rising sea levels have pushed, is already unrealistic. (That cap is often compared to a speed limit for warming; while some consequences — heat waves, species loss and so on — are expected to occur at lesser levels of warming, the repercussions are expected to become more dire as warming increases.)
> Reductions would need to begin by 2027 for the more widely accepted 3.6-degree F (2 degrees C) cap to be achievable, and a 4.5 degree F (2.5 degree C) cap becomes unrealistic after 2040, he calculates.
We were at 0.65C then.
Now, a year after the industrial world shut down to the point that rivers ran clear, it's 0.89C.
