Abstract
Improved knowledge of glacial-to-interglacial global temperature change yields Charney (fast-feedback) equilibrium climate sensitivity 1.2 ± 0.3°C (2σ) per W/m2, which is 4.8°C ± 1.2°C for doubled CO2. Consistent analysis of temperature over the full Cenozoic era—including ‘slow’ feedbacks by ice sheets and trace gases—supports this sensitivity and implies that CO2 was 300–350 ppm in the Pliocene and about 450 ppm at transition to a nearly ice-free planet, exposing unrealistic lethargy of ice sheet models. Equilibrium global warming for today’s GHG amount is 10°C, which is reduced to 8°C by today’s human-made aerosols. Equilibrium warming is not ‘committed’ warming; rapid phaseout of GHG emissions would prevent most equilibrium warming from occurring. However, decline of aerosol emissions since 2010 should increase the 1970–2010 global warming rate of 0.18°C per decade to a post-2010 rate of at least 0.27°C per decade. Thus, under the present geopolitical approach to GHG emissions, global warming will exceed 1.5°C in the 2020s and 2°C before 2050. Impacts on people and nature will accelerate as global warming increases hydrologic (weather) extremes. The enormity of consequences demands a return to Holocene-level global temperature. Required actions include: (1) a global increasing price on GHG emissions accompanied by development of abundant, affordable, dispatchable clean energy, (2) East-West cooperation in a way that accommodates developing world needs, and (3) intervention with Earth’s radiation imbalance to phase down today’s massive human-made ‘geo-transformation’ of Earth’s climate. Current political crises present an opportunity for reset, especially if young people can grasp their situation.
My basic summary (I am NOT a climate scientist so someone tell me if I’m wrong and I HOPE this is wrong for my children), scientists had dismissed hotter climate models due to the fact that we didn’t have historical data to prove them. Now folks are applying hotter models to predicting weather and the hotter models appear to be more accurate. So it looks like we’re going to break 2C BEFORE 2050 and could hit highs of 8C-10C by the end of the century with our CURRENT levels of green house gases, not even including increasing those.
Omg you’re a fucking idiot. This has been well studied get educated
You fucking idiot, stop reading studies that only support your world view. If everyone goes vegan we’ll have to farm a LOT more of monocultures and specific things like peanut, soy and tofy that are very harmful for the environment. A cow eats about every grass you feed it, there’s no monoculture required unless you’re mass producing meat based on industrialized cattle feed.
The solution for the food problem is simple: evolve lab produced meat processes so they became cheap and environmentally friendly. Cutting meat from our diet will be harmful for us and that’s mostly proven by now. From woman who lose their period when they stop eating meat to anemia, and muscle wasting everything happens. Substitutes are different kinds of proteins that while may work to some degree aren’t as good.
Who the fuck said everyone had to be a vegan you fucking muppet
What do you suppose they already grow to feed the majority of the meat animals we eat?
We already produce more than enough food to feed the planet, and we’d have 10x more if we ate what we feed industrially farmed animals.
You can’t eat that or that alone and what you can and need is way worse for the environment.
Who suggested eating it alone? We already eat a wide variety of food that isn’t animal based, this would continue if we replaced meat with soy.
Way worse for the environment? How so?
