It takes and hopefully soon we will meet in 3D.

Just last weekend I was able to go to Siam conference

and seeing all friends in person

it was a pleasant experience.

So as I was mentioning in the casual conversation

before the start of the talk,

on the fly when they kindly invited me to jump in

on an opening, I decided to bring this topic

of climate change.

And so the first thing I want to say,

I'm just, I'm not fully involved in it.

I want to jump in, but I hope the talking points

throughout the talk will tell you why

I decided to bring in this topic, the timing of it

and the hope that this community also gets engaged

in the modeling of climate.

So already on slide one, there is a little bit

of an explanation of the why now.

So the left figure has North Texas,

the view of North Texas in February of this year

an unusual winter storm that had never been seen

in this part of the country.

And far down in the talk, I will highlight

one of the very recent papers where the connection

of the main driver of climate in Europe

may have a weakening of that may have something to do

with this unusual cold weather.

On the right-hand side, there is a picture

of the current comparison of temperatures

in the two month window, September,

June to September, 2021, compared to the last 30, 40 years

and red that the underlying is a lot of red.

So that's the warming compared

to historical average temperatures.

In the middle, it was refers a little bit of the time

about 10 years ago where I was, a group of us

applied mathematicians were more involved in a network

that was created, supported by the National Science

Foundation, where the whole idea at that time was something

like we will try to reenergize this.

Those of us who are not fully committed,

we're not doing the large scale scientific computing

can still learn and contribute.

In a similar way as we did, where were we

as we were grounded and the lessons learned

and that was a COVID experience.

So I highlight in this slide, three points.

One is, what we did when we were grounded

on the left, it reflects a little bit of an effort

with an undergrad student to study the COVID-19 in Texas.
