The earth is warming. The previous seven years are on observe to be the seven warmest on report. The emissions of greenhouse gases from human actions are accountable for roughly 1.1°C of common warming because the interval 1850-1900.
What we’re experiencing could be very totally different from the worldwide common. We experience extreme weather — historic droughts, unprecedented heatwaves, intense hurricanes, violent storms, and catastrophic floods. Local weather disasters are the brand new norm.
We have to confront climate change now. But, we received’t really feel the affect of our efforts for many years. It’s laborious to mobilize motion for one thing up to now sooner or later. However we should know our future in the present day — see it and really feel it — so we will act with urgency.
To make our future a actuality in the present day, simulation is the answer.
To develop the very best methods for mitigation and adaptation, we want local weather fashions that may predict the local weather in numerous areas of the globe over many years.
In contrast to predicting the climate, which primarily fashions atmospheric physics, local weather fashions are multidecade simulations that mannequin the physics, chemistry, and biology of the ambiance, waters, ice, land, and human actions.
Local weather simulations are configured in the present day at 10- to 100-kilometer resolutions.
However larger decision is required to mannequin modifications within the international water cycle — water motion from the ocean, sea ice, land floor, and groundwater by the ambiance and clouds. Modifications on this system result in intensifying storms and droughts.
Meter-scale decision is required to simulate clouds that mirror daylight again to area. Scientists estimate that these resolutions will demand tens of millions to billions of instances extra computing energy than what’s at present accessible. It might take many years to attain that by the extraordinary course of computing advances, which speed up 10x each 5 years.
For the primary time, we’ve got the know-how to do ultra-high-resolution local weather modeling, to leap to lightspeed, and predict modifications in regional excessive climate many years out.
We will obtain million-x speedups by combining three applied sciences: GPU-accelerated computing; deep studying and breakthroughs in physics-informed neural networks; and AI supercomputers, together with huge portions of noticed and mannequin information to study from.
And with super-resolution methods, we might have inside our grasp the billion-x leap wanted to do ultra-high-resolution local weather modeling. Nations, cities, and cities can get early warnings to adapt and make infrastructures extra resilient. And with extra correct predictions, individuals and nations will act with extra urgency.
So, we’ll dedicate ourselves and our important assets to direct NVIDIA’s scale and experience in computational sciences, to hitch with the world’s local weather science neighborhood.
NVIDIA this week revealed plans to construct the world’s strongest AI supercomputer devoted to predicting local weather change. Named Earth-2, or E-2, the system would create a digital twin of Earth in Omniverse.
The system could be the local weather change counterpart to Cambridge-1, the world’s strongest AI supercomputer for healthcare analysis. We unveiled Cambridge-1 earlier this yr within the U.Ok. and it’s being utilized by quite a few main healthcare corporations.
All of the applied sciences we’ve invented as much as this second are wanted to make Earth-2 attainable. I can’t think about a larger or extra essential use.

Jensen Huang based NVIDIA in 1993 and has served since its inception as president, chief govt officer, and a member of the board of administrators. In 2017, he was named Fortune’s Businessperson of the Yr. In 2019, Harvard Enterprise Evaluate ranked him No. 1 on its listing of the world’s 100 best-performing CEOs over the lifetime of their tenure.
