/[ Examine Venus]/
*Earth may seem like a one-of-a-kind planet, but it actually has a twin*

The twin is Venus — the hottest planet in our solar system. Our series 
on The Science of Siblings, examines how these two planets started out 
so similar but end up so different.

GILMORE: If you were an alien visiting our solar system 4 billion years 
ago, you would see three rocky planets, each of which have oceans.

BARBER: Their locations and sizes affected all three planets. Let's talk 
about size first. Size determines if that planet stays hot from its 
initial creation. When Gilmore is talking to her class, this is how she 
puts it.

GILMORE: It's like Thanksgiving. You have a hot potato, you know, a 
baked potato, and you've got peas. And you want to eat that potato, but 
it's too hot. But the peas - they're ready to go, because they have 
radiated out their heat because they're small.

BARBER: Mars isn't exactly a pea, but it is smaller than Earth and 
Venus. It cooled off pretty fast, but...

GILMORE: Venus and Earth are the same size potatoes.

BARBER: They both were about the same temperature to start. They both 
were made of pretty much the same stuff. They both had active volcanoes, 
and these were releasing greenhouse gases like carbon dioxide to create 
an atmosphere. And they both had oceans that could store any excess 
carbon dioxide.

GILMORE: By all of our understanding, Venus and Earth should have been 
the same.
BARBER: ...But they're not. And that's because of one big difference. 
Venus is a bit closer to the sun. Think of twins separated at birth, 
growing up in very different environments. Venus got too hot being too 
close to the sun. Its oceans dried up.

GILMORE: And once you get rid of an ocean, you turn off the major 
mechanism to store carbon dioxide in rock. And therefore, it just stays 
in the atmosphere, and the greenhouse effect takes over.

BARBER: You may have heard of the greenhouse effect. Scientists think 
about it a lot because of its role in global warming on Earth. So 
studying Venus can show us what happens when this effect gets out of 
control. Gilmore has so many other questions when it comes to Venus. Can 
Venus show us how our planet operated billions of years ago, before 
plate tectonics altered volcanoes, mountains, seas and climate? Can it 
tell us what to look for as we search for habitable planets across the 
galaxy? She likens Venus to dozens of exoplanets like Earth that 
scientists have found outside of our solar system.

GILMORE: I mean, those are, like, our long-lost cousins that you find 
when you go on, like, AncestryDNA or whatever, you know, 23andMe. And 
you're like, what? Who's that? (Laughter) That's those exoplanets.

BARBER: We won't be able to visit those distant planets in the near 
future, but we can actually visit Venus. With three upcoming missions to 
Venus from NASA and the European Space Agency, we might soon be able to 
answer these questions.

/[ The speeding-up of the heating-up - Acceleration  ]/
*Is Global Warming Speeding Up?*
ClimateAdam
Apr 5, 2024  #ClimateChange #climatecrisis
Thanks to climate change, 2023 has shattered heat records, and 2024 is 
continuing where last year left off. With this devastating heat driving 
extreme weather - from heatwaves to downpours to wildfires - across the 
globe, scientists are increasingly asking if global warming could be 
accelerating. So what does the evidence show? Is the heating up of our 
planet speeding up? If so, what does this climate change mean for our 
future? And can we still hit the brakes and halt global warming?

*Global Warming Acceleration: Hope vs Hopium*
29 March 2024
James Hansen, Makiko Sato, Pushker Kharecha
Accumulating evidence supports the interpretation in our Pipeline paper: 
decreasing human-made aerosols increased Earth’s energy imbalance and 
accelerated global warming in the past decade.
Climate sensitivity and aerosol forcing, physically independent 
quantities, were tied together by United Nations IPCC climate 
assessments that rely excessively on global climate models (GCMs)and 
fail to measure climate forcing by aerosols. IPCC’s best estimates for 
climate sensitivity and aerosol forcing both understate reality.
Preservation of global shorelines and global climate patterns – the 
world humanity is adapted to – likely will require at least partly 
reversing global warming. Required actions and time scale are undefined. 
A bright future for today’s young people is still possible, but its 
attainment is hampered by precatory (wishful thinking) policies that do 
not realistically account for global energy needs and aspirations of 
nations with emerging economies.
An alternative is needed to the GCM-dominated perspective on climate 
science. We will bear a
heavy burden if we stand silent or meek as the world continues on its 
present course.
Our paper, Global Warming in the Pipeline, was greeted by a few 
scientists, among the most active in communication with the public, with 
denial. Our friend Michael Mann, e.g., with a large public following, 
refused to concede that global warming is accelerating. We mention Mike 
because we know that he won’t take this notation personally.
Accelerated global warming is the first significant change of global 
warming rate since 1970.
It is important because it confirms the futility of “net zero” hopium 
that serves as present
energy policy and because we are running short of time to avoid passing 
the point of no
return. We will focus on advancing our research now and completing 
Sophie’s Planet in 2024, so we must limit our interactions this year. We 
will send out updates every other month for the remainder of this year, 
as described in a recent note.
  This is the March update.

In this Our Changing Climate climate change video essay, I dive into the 
worst-case climate change scenarios that could possibly lead to societal 
collapse. Specifically, I understand what the literature says will 
happen above four degrees of global warming in turns of natural 
disasters, as well as how that will unfold across our economic and 
social webs.

*Naomi Oreskes: Why we should trust scientists*
TED
Jun 25, 2014
Many of the world's biggest problems require asking questions of 
scientists — but why should we believe what they say? Historian of 
science Naomi Oreskes thinks deeply about our relationship to belief and 
draws out three problems with common attitudes toward scientific inquiry 
— and gives her own reasoning for why we ought to trust science.

April 6, 2000: Predicting the controversies that would define the George 
W. Bush administration, New York Times columnist Bob Herbert observes, 
"Mr. Bush's relationship to the environment is roughly that of a doctor 
to a patient -- when the doctor's name is Kevorkian."
