President Joe Biden announced a new goal to sharply cut down US greenhouse gas emissions this decade. The country’s new mandate is to reduce planet-heating gases by 50 to 52 percent of what the US emitted in 2005. It significantly ramps up a previous commitment under the Paris climate agreement made by former President Barack Obama, who pledged to slash emissions between 26 to 28 percent below 2005 levels by 2025.

The US hopes to regain respect on the international stage

The urgency for the US to gut its climate pollution has only grown since the Paris Agreement was adopted in 2015. Global carbon dioxide emissions need to drop by half this decade and reach close to zero by the middle of the century in order to hit the goals of the Paris Agreement and prevent some of the most devastating effects of climate change, a landmark 2018 report found. The US has a huge role to play as the second biggest greenhouse gas polluter after China. But it abdicated leadership on the climate front under former President Donald Trump, who briefly pulled the US out of the Paris accord and drastically rolled back environmental regulations in the US. 

Now the US hopes to regain respect on the international stage when it comes to tackling the climate crisis. Biden will hold his own virtual summit on climate today (Earth Day) and tomorrow aimed at encouraging other countries to ratchet up their goals. All countries are expected to update their individual commitments to combating climate change ahead of a United Nations climate conference scheduled to take place in November.

“[The Biden administration is] very cognizant that the US as a credible actor and leader in this space really depends in large measure on having a really robust new target,” says Pete Ogden, vice president for energy, climate, and the environment at the United Nations Foundation.

Major environmental groups like Sierra Club have pushed the Biden administration to target a reduction of at least 50 percent. Hundreds of businesses, including Amazon, Apple, and General Motors, did also.

Michael Mann, a climate scientist at Pennsylvania State University, told the Associated Press that the 50 percent goal “is precisely what is needed ... an actionable goal within the next decade that puts us on the path toward limiting warming below a catastrophic 1.5 degrees Celsius.″  The Paris agreement seeks to stop global average temperatures from rising 1.5 degrees Celsius above preindustrial levels, a threshold that scientists project would lead to catastrophic effects.

Some progressive groups called for deeper emissions cuts, citing the US’s history of contributing more to the climate crisis than any other country. “There exists in my mind no possible ethically justifiable story in which the United States does not do more,” said Tom Athanasiou, executive director of the activist think tank EcoEquity, which is part of a network that has called on the US to reduce its emissions by at least 70 percent below 2005 levels this decade. 

More countries are expected to ratchet up ambitions this week during Biden’s climate summit. The UK announced on April 20 that it plans to cut its greenhouse gas emissions by 78 percent compared to 1990 levels by the year 2035. 

“This is a dire warning.”

Those commitments couldn’t come any sooner as climate pollution continues to grow. After a temporary drop in planet-warming CO2 emissions during the pandemic, annual emissions this year are on course for the sharpest rise since 2010. 

“This is a dire warning that the economic recovery from the Covid crisis is currently anything but sustainable for our climate,” Fatih Birol, executive director of the International Energy Agency, said in a statement about the new estimate for 2021 emissions. “Unless governments around the world move rapidly to start cutting emissions, we are likely to face an even worse situation in 2022.”

Missing classic Mario?

One fan, who goes by the name Metroid Mike 64 on Twitter, just built a full-on 2D Mario game inside Super Mario Maker 2 complete with 40 levels and eight worlds.

Looking at the gameplay shared on Twitter is enough to make me want to break out my SNES, or at least buy Super Mario Maker 2 so I can play this epic retro revamp.

The US might still force TikTok into a data security deal with Oracle.

The New York Times says the White House is still working on TikTok’s Trump-era data security deal, which has been in a weird limbo for nearly two years now. The terms are basically the same: Oracle plays babysitter but the app doesn’t get banned. Maybe it will happen now, though?

Netflix’s gaming bet gets even bigger.

Even though fewer than one percent of Netflix subscribers have tried its mobile games, Netflix just opened up another studio in Finland after acquiring the Helsinki-based Next Games earlier this year.

The former vice president of Zynga Games, Marko Lastikka, will serve as the studio director. His track record includes working on SimCity BuildIt for EA and FarmVille 3.

Vietnam’s EV aspirant is giving big Potemkin village vibes

Idle equipment, absent workers, deserted villages, an empty swimming pool. VinFast is Vietnam’s answer to Tesla, with the goal of making 1 million EVs in the next 5-6 years to sell to customers US, Canada and Europe. With these lofty goals, the company invited a bunch of social media influencers, as well as some auto journalists, on a “a four-day, multicity extravaganza” that seemed more weird than convincing, according to Bloomberg.

Today, 39 years ago, the world didn’t end.

And it’s thanks to one man: Stanislav Petrov, a USSR military officer who, on September 26th, 1983, took the decision not to launch a retaliatory nuclear attack against the US. Petrov correctly guessed that satellite readings showing inbound nukes were faulty, and so likely saved the world from nuclear war. As journalist Tom Chivers put it on Twitter, “Happy Stanislav Petrov Day to those who celebrate!” Read more about Petrov’s life here.

Deepfakes were made for Disney.

You might have seen the news this weekend that the voice of James Earl Jones is being cloned using AI so his performance as Darth Vader in Star Wars can live on forever.

Reading the story, it struck me how perfect deepfakes are for Disney — a company that profits from original characters, fans' nostalgia, and an uncanny ability to twist copyright law to its liking. And now, with deepfakes, Disney’s most iconic performances will live on forever, ensuring the magic never dies.

Thousands and thousands of reasons people love Android.

“Android fans, what are the primary reasons why you will never ever switch to an iPhone?” That question led to almost 30,000 comments so far, and was for a while the most popular thing on Reddit. It’s a totally fascinating peek into the platform wars, and I’ve spent way too much time reading through it. I also laughed hard at “I can turn my text bubbles to any color I like.”
