Yes, the climate has always changed.

But, the speed of recent change is unprecedented.

More importantly, we understand why.

Burning fossil fuels & deforestation adds carbon dioxide to the atmosphere which warms the planet.

Simple physics. Understood for more than a century.

Sí, el clima siempre ha cambiado y cambiará.

Pero mire las escalas temporales.

Pero la velocidad del cambio reciente no tiene precedentes.

And everyone who offers the argument that it is the natural course of things is a liar or incredibly stupid. Most of the latter are delusional, thinking some guy in the sky created this and knows what "he" is doing and we should keep on f-ing it up because that is "his" plan. They should have NO place in policymaking. They should be institutionalized. Maybe deep sea vent creatures will survive, unless Earth becomes Venus. Might take 1000 years, but once past the ponr, it's over.

Hmm, that's both odd (picking neither a base around the sole "Invention of the Steam Engine" event singled out, nor a pre-industrial average) and surprising (it certainly doesn't look like that from the graphic.)

@ed_hawkins The debate is not whether the climate change is real or not, but how we tackle fossil fuel emissions without destroying the economy which runs on fossil fuels and avoiding social turmoil. i.e. Sri Lanka (top ESG score before the collapse).

Keep in mind that most solutions proposed by climate change advocates are long term scams, delaying the transition to sustainable renewable energy and enriching legacy petrochemical corporations e.g. Green Hydrogen, Biomass, bio-fuels, carbon credit, etc.

@ed_hawkins Also, "the climate is always changing" implies high climate sensitivity, so it's a reason to be even more worried.

@ed_hawkins we are, in a couple of centuries, undoing millions of years of natural carbon sequestration. The result is relatively rapid climate changes, and rapid change means high adaptation costs. We can mitigate those costs by moderating our fossil carbon consumption. I really don’t understand what is the least bit controversial about those statements.

Only problem for most conservatives in the US is that they believe the ignorant and willfully uninformed former President Trump and disbelieve state-of-the-art science.

@ed_hawkins What explains the Cambrian period, where CO2 was higher, climate was warmer, and Flora, and Fauna thrived. Including many giant species. Don't get me wrong, pollution and our lack of response to it is disappointing. Surely, that motivates us to really nail down our science. Hypothesis is support by observation until just one observation breaches the hypothesis. It seems we have many breaches, so I am struggling to remain convinced by the science.

@RickTimmis @ed_hawkins What do you mean? Back in the Cambrium, no life existed on land yet. Did you mix it up with another period? CO2 levels have been higher in the past - but the change has never been as abrupt, and we humans were never alive. Also, what breach do you mean?

Apologies I meant the Holocene, also called the Flambrian period.

https://en.m.wikipedia.org/wiki/Holocene

The breached I am talking about are the modelling. We have had several predictions including it's going to get cold (1970's) This makes me question the quality of the science. Don't get me wrong, I am not saying we should not be responsible and take good care of our world 🌎.

I guess I just want there to be an open dialogue, of discovery and, where we are united, rather than divided.

@RickTimmis @ed_hawkins The prediction that the future would be colder than the present from the 1970's is exactly that - it's from the Seventies, climate change only has been widely understood since the 1980's. Since then, the models have become more and more accurate. And by now, effects are easily visible just from data gathered in the last decades, without any models involved.

@Geo @ed_hawkins Well OK, but I'm still scratching my head when I watch the daily weather forecast. Probability would be just as good. I just worry that in our Race to Slow the rate of carbon generation, we bring about something much worse. Wiping massive swages of land out of agriculture to deploy solar panels, for example.
I think we need a collective mindset to simplify our lives, and reduce consumption. This is not the same as a global agenda on carbon. 🥰

@RickTimmis @ed_hawkins I don't understand your question. What explains when the earth was warmer? You just described a similar situation except that our current change is happening extremely rapidly due in part to the release of millennia worth of sequestered CO2. We're driving the change now.

Radical altering of environment, of the "life envelope" we live in.

The Canadian "Wildfire season" has NOT YET STARTED. More trees burned than any fire season in known history, and the fire season HASNT YET STARTED.

Canadian wildfire season starts in 2 weeks, and more hectares have burned than in any previous year.

New York City, hundreds of miles away has the worst air in its history, from smoke of a burning continent.
