<i>[ Examine Venus]</i><br>
<b>Earth may seem like a one-of-a-kind planet, but it actually has a
twin</b><br>
APRIL 5, 2024<br>
HEARD ON MORNING EDITION<br>
Regina G. Barber<br>
- -<br>
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.<br>
<p>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.</p>
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.<br>
<br>
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.<br>
<br>
BARBER: Mars isn't exactly a pea, but it is smaller than Earth and
Venus. It cooled off pretty fast, but...<br>
<br>
GILMORE: Venus and Earth are the same size potatoes.<br>
<br>
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.<br>
<br>
GILMORE: By all of our understanding, Venus and Earth should have
been the same.<br>
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.<br>
<br>
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.<br>
<br>
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.<br>
<br>
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.<br>
<br>
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.<br>

<b>Is Global Warming Speeding Up?</b><br>
ClimateAdam<br>
Apr 5, 2024 #ClimateChange #climatecrisis<br>
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?<br>

<b>Global Warming Acceleration: Hope vs Hopium</b><br>
29 March 2024<br>
James Hansen, Makiko Sato, Pushker Kharecha<br>
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.<br>
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. <br>
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.<br>
An alternative is needed to the GCM-dominated perspective on climate
science. We will bear a<br>
heavy burden if we stand silent or meek as the world continues on
its present course.<br>
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.<br>
Accelerated global warming is the first significant change of global
warming rate since 1970.<br>
It is important because it confirms the futility of “net zero”
hopium that serves as present<br>
energy policy and because we are running short of time to avoid
passing the point of no<br>
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.<br>
This is the March update.<br>

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. <br>

<b>Naomi Oreskes: Why we should trust scientists</b><br>
TED<br>
Jun 25, 2014<br>
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.<br>
