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.

Cattle have numerous impacts on Earth’s climate and natural environments, despite misconceptions. (science.feedback.org)

Summary.

Studies have shown that cattle farming operations – even ones that are perceived to be ‘better’ like pastured operations – have negative climate and environmental impacts. Numerous cattle pastures in Brazil, for example, are created through deforestation. Cattle production can also drive land degradation, soil acidification, and overabundance of nutrients that disrupt the balance of aquatic ecosystems. Planet-warming greenhouse gases are also emitted throughout the entire cattle-product lifecycle, from farming operations to final product. Beef products, for example, have the highest carbon footprint of any food product (per kilogram produced). Several mitigation measures have been proposed by scientists for these issues; however, viral online misinformation continues to mislead people to greatly underestimate the impacts above.

cattle populations grew from 942 million to 1.5 billion globally – a roughly 63% increase.

~~No, that's roughly a 47% increase.~~

Lol, I can't math either. Should be 36%, which is still (too) much.

942 mio × (1 + x) = 1500 mio
0.942 × (1 + x) = 1.5
x = (1.5/0.942) - 1
x = 0.59

Using this formula I got a 59% increase, which may very well be within truncation error range (1.535 mio is 163% of 943 mio).

Did you get to 36% by calculating the change starting from the increased value? When talking about percentage increase the increase is usually given relative to the previous value.
