🌏 We only have three years left to avert the worst consequences of #climate change, a sobering report from the @UN warned on Monday.

Here are the 5️⃣ solutions that scientists say can make a dent in the #ClimateCrisis right now. 👇

1️⃣ Cities and urban areas make up two-thirds of all global emissions, according to the new #IPCCReport.

🚌 Redesigning urban transportation could cut about one-quarter of those emissions by 2050.

2️⃣ In 2019, energy suppliers produced about 34% of all human-driven emissions worldwide, according to the IPCC report.

🔈Climate scientists' core message: We must stop using fossil fuels as quickly as possible.

3️⃣ Nearly one-fifth of all the energy sector's emissions are methane — a powerful gas with 30 times the heat-trapping potential of carbon dioxide.

💨 A drop in methane emissions can help rapidly reduce the speed of #GlobalWarming.

4️⃣ Landfills are the third-largest source of methane emissions in the US, and food waste is the largest category of garbage.

🥬 Wasting less food is a simple lifestyle change that individuals can make in developed countries.

5️⃣ Trees thrive by absorbing carbon dioxide from the air and storing it in their tissues — a powerful tool to fight the climate crisis.

🌳The IPCC report calls for protecting forests across the planet from deforestation and planting more.

"There are no silver bullets. We need to do it all," @stephanieroe, a lead author on the report and a climate scientist at @WWF, told @thisisinsider.

You've probably heard that sugar is bad for you and that you should cut it out of your diet, but how true are these statements?

We spoke with dietitians Mary Matone and Meredith Rofheart to debunk common myths about sugar. 👇
Think you know everything about sugar? Put your knowledge to the test.

True or false: Sugar is bad for you.
The body needs sugar, Matone said.

"It just comes down to what kind of sugar we need more often and what kind of sugar we should be limiting most of the time," she added.

The message of the most recent @UN climate change report? “Delay means death."

@jake_bittle breaks down a few of the most urgent and important ways governments need to adapt if they want to manage and avoid more climate-driven catastrophes. ⬇️

businessinsider.com/climate-change…
The UN report compiles decades of research on how to adapt to climate change, proposing hundreds of solutions that can reduce the human and financial cost of climate disasters.

1️⃣ Build a better power grid.

Increasingly volatile weather patterns mean that every region of the country needs to invest in beefing up its power grid, experts say.

NASA calls the annual Perseids meteor shower the best of the year, thanks to the many bright meteors that streak across the night sky.

Before the 2021 Perseids shower peaks tonight, learn what you’ll actually be seeing.

Unlike the solar eclipse and aurora, meteor showers occur the same time each year and have been doing so for centuries.

Photo showing the Perseids meteor shower.
While meteor showers look stellar, there are only three ingredients needed to make them: the Sun, Earth, and a comet.

A long-awaited report was published today by The Intergovernmental Panel on Climate Change (@IPCC_CH).

It states that Earth's oceans and ice won't recover from the effects of climate change for millennia.

Here are the main takeaways. 👇

The report suggests that Earth won't be the same again for thousands of years.

Human activities have altered our planet's systems so dramatically that seas will continue to rise and glaciers continue to melt long after the 21st century ends.

🧊 The Arctic permafrost.

The layer of soil that used to stay frozen year-round is thawing due to rising temperatures.

This causes carbon to be released into the atmosphere, where it traps heat and contributes to additional warming.

Three joint space missions are aiming to bring soil samples back from Mars. If they succeed, the dirt will be the most expensive substance known to mankind.

So why is Martian soil so expensive? And what could it reveal to us about extraterrestrial life?

On February 18, 2021, the Perseverance rover touched down on Mars, after a seven-month voyage through 300 million miles of space.

It’s a feat considering only 40% of missions to Mars have been successful.

This first phase cost NASA $2.7 billion.

But landing on Mars is just the beginning of a space endeavor so ambitious and sophisticated that each component must go exactly according to plan.

“Space is a one-strike-and-you’re-out business,” explained Scott Hubbard.

🛰️ @NASA shared an image of dunes surrounding Mars' northern polar cap this week.

The photo has been released to mark the 20th anniversary of the Mars Odyssey orbiter. 👇

🛰 The photo captures a sea of dunes and wind-sculpted lines surrounding the red planet's frosty northern polar cap.

The shot represents an area that is 19 miles wide, NASA said. But the sea of dunes actually covers an area as large as Texas. businessinsider.com/mars-nasa-shar…
🛰️ The photo is a false color image, meaning that the colors are representative of temperatures.

Blue represents cooler climes, and the shades of yellow mark out "sun-warmed dunes," the US space agency said.
