It’s hard to avoid news of global warming and climate change. At approximately 415 parts-per-million (ppm), many scientists believe that earth’s carbon dioxide (CO2) levels are as high as they’ve been since the Miocene era approximately 15 million years ago¹. At this time, there were trees in Antarctica, equatorial regions were uninhabitable, and our earliest ancestors were not yet walking upright.

The earth’s changing climate may be the cause of severe local weather conditions in North America. In just the past weeks we’ve seen record flooding in Iowa, Illinois, Ontario and Quebec, a national disaster in Nebraska, a bomb cyclone in South Dakota, and a multi-day weather event that saw 52 tornados touch down across seven states putting 50 million people at risk. All this and it’s only May – hurricane season hasn’t even started yet.

Accurate forecasting becomes essential

With more frequent and severe weather events, accurate short- and medium-term weather forecasting will be critical. Aside from weather-related emergency alerts, airlines will need better forecasting to plan flight routes to avoid damaging turbulence and costs due to more frequent weather disruptions. Farmers will need to know when to plant, fertilize, and harvest to optimize crop yields. Utility companies will need better forecasts to help them pre-position assets to address increasingly severe storm damage to critical infrastructure.

How weather modeling works

Weather modeling is essentially a computational fluid dynamics (CFD) problem. Much like simulating airflow over an airplane wing, the basic idea behind weather forecasting

Looking forward to new factions in Battlefield 5? It seems DICE has sneakily slotted in the Battlefield 5 US faction, and the Japan faction in its latest patch.

Thanks to Battlefield dataminer temporyal, we get to see evidence of this, plus pictures of unreleased gadgets, news on being a Battlefield 5 Firestorm respawn feature and more!

US and Japanese factions arrived (secretly)

DICE took first steps towards individual factions for the Pacific and implemented the US and Japanese as seperated parts in the company. Take a look at this image to understand what happened behind the curtain:

Explanation:

Before the patch we had just Allies and Axis depicting UK and Germany. These parts were internally renamed to “Allies – UK” and “Axis – Germany”. Though not visible DICE additionally added “Allies – US Pacific” and “Axis – Japan” next to the existing factions.

Note: The faction titles in the second part of the image were done by myself because the internal names (“Allies – US Pacific”,…) are just too long. We’ll see what DICE is going to choose in Tides of War Chapter

Drone designer Adam Woodworth has done some amazing designs in the past — from Imperial Star Destroyers to F-22 Raptors — but this giant Lego helicopter is clearly his best yet. Check it out in action:

The drone — presented at this year’s Makers Fair in the Bay Area — is amazing for several reasons. First, it looks just like real Lego — with each piece cut and painted to perfection, including the classic minifig pilot. In fact, the drone actually reproduces a helicopter from a real Legoland set, hthe classic set 6396 International Jetport — which Woodworth says it was always his favorite of the Lego helicopters.

Of course, the rotor is just for show. It even moves at the same speed of other motorized Lego helicopters.

The helicopter is ten times the scale of a real minifig. The large scale allowed him to “build it perfectly with 1-inch insulation foam with a couple pieces of depron foam”, an insulation foam
