Climate - truthful information about climate, related activism and politics.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Take a look at these quotes from articles from the past 120 years. What can we make from them? Is climate change actually a big of a deal as it's claimed? The fact that "climate change" is such political issue gives me doubt. Any political talking point should always be scrutinized and criticized. Politicians have an agenda and will use anything they can to push that agenda.

I'm not here to argue about climate change being real or not. Rather, I would like opinions about the website I shared

A link to the primary source research. All you have provided is unverified claims about "he said, she said" from a questionable source. That's not science.

It's not about science here or any particular scientific research... it's about how media outlets have been publishing articles by authors who claim the earth is warming or cooling and we are doomed very soon. And that this type of climate fear mongering (also, true or not, it is fear mongering) has been going around since 1900.

You seem to be either looking for someone to agree with you that a website by some scientific nobody casts the predictions about the dire outlook because of climate change into doubt. If so, you are in the wrong community and are definitely sealioning and attempting to spread misinformation.

As I've said repeatedly, informed people don't look at websites like that, because they know they are used to generate FUD.

I've lived the consequences of climate change. I've fought fires burning in rainforest, where it has NEVER before burned. I've seen fires and floods unprecedented in scale. We are seeing warming 5 standard deviations above average. If you know a little about data science as you seem to imply, you know exactly what that means. The warning signs are clear and present. I'm past the point of giving people like Mark Simone the slightest benefit of the doubt.

Despite the narrative from mouthpieces like Mark Simone, the IPCC is actually a VERY conservative body. They have to release information which is able to stand up to rigorous scrutiny and challenge, and not upset established interests like governments and fossil fuel companies too much.

To quote the latest IPCC report (my emphasis added):

Human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming, with global surface temperature reaching 1.1°C above 1850-1900 in 2011-2020. Global greenhouse gas emissions have continued to increase, with unequal historical and ongoing contributions arising from unsustainable energy use, land use and land-use change, lifestyles and patterns of consumption and production across regions, between and within countries, and among individuals (high confidence).

Widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere have occurred. Human-caused climate change is already affecting many weather and climate extremes in every region across the globe. This has led to widespread adverse impacts and related losses and damages to nature and people (high confidence). Vulnerable communities who have historically contributed the least to current climate change are disproportionately affected (high confidence).

Adaptation planning and implementation has progressed across all sectors and regions, with documented benefits and varying effectiveness. Despite progress, adaptation gaps exist, and will continue to grow at current rates of implementation. Hard and soft limits to adaptation have been reached in some ecosystems and regions. Maladaptation is happening in some sectors and regions. Current global financial flows for adaptation are insufficient for, and constrain implementation of, adaptation options, especially in developing countries (high confidence).
