Recently, period underwear has risen in popularity to prevent the unnecessary waste that comes from using these products.

Period panties are a newer form of menstrual care that can both replace the need for disposable hygiene products and be a solution for preventing messy leaks. They're an ecologically smart alternative to single-use period products and a great long-term investment for those who want a more comfortable and easier menstrual solution.

We can learn a lot about climate change from Venus, our sister planet. Venus currently has a surface temperature of 450℃ (the temperature of an oven's self-cleaning cycle) and an atmosphere dominated by carbon dioxide (96 percent) with a density 90 times that of Earth's.

Climate Explained is a collaboration between The Conversation, Stuff and the New Zealand Science Media Centre to answer your questions about climate change.

If you have a question you'd like an expert to answer, please send it to [email protected]

Earth had several periods of high carbon dioxide levels in the atmosphere and high temperatures over the last several million years. Can you explain what caused these periods, given that there was no burning of fossil fuels or other sources of human created carbon dioxide release during those times?

Burning fossil fuels or vegetation is one way to put carbon dioxide into the air – and it is something we have become very good at. Humans are generating nearly 40 billion tons of carbon dioxide every year, mostly by burning fossil fuels.

Let's take a look at the best dry herb vaporizers. Our goal here is to help you find the right portable vaporizer that you can discretely carry to smoke the herb of your choice. Whether buying to use with hemp flower or a more THC-heavy cannabis strain, we can help you find the handheld heating chamber most likely to produce a boundless flow of quality vapor.

We understand there's a big market for desktop vaporizers. And if battery life is a big concern, it's always nice to be connected to a wall for long sessions. But here we are talking about the mighty and small devices you can carry with you. These you can count on for a smooth vape experience.

As you read this, keep in mind there are a number of ways to ingest CBD or THC that don't require smoking or inhaling vapor. Oils, gummies, and capsules may be a better way to take certain cannabinoids. With that in mind, our round-up of the best dry herb vaporizers for sale online.

Top 5 Best Dry Herb Vaporizer List

PAX 3 Vaporizer - Best Overall

Slick Vapes

The PAX 3 heats up to deliver smoke within 15 seconds, and consequent heat-ups come quickly too. That's what makes this product a standout. It keeps heat and gets you to good faster than most dry herb vapes. Pax is a brand known for its vapor quality and durable vape bodies. The brand's portable devices use a conduction heating system and a strong 3500 mAh battery, which will last about ten sessions. Keep in mind, quick heat means the potential for burnt herb, so pay attention as you get started.

Why Buy: works with dry herb and concentrates; comes with a 10-year warranty; connects to your phone via bluetooth; and comes with a free acrylic grinder

DAVINCI IQ2 Vaporizer - Smoothest Flow

Slick Vapes

The DaVinci IQ2 Dry Herb Vaporizer touts better airflow and stronger, faster conduction heating than previous models from the brand. Plus, the anodized aluminum shell is built for durability—whether you're tossing your vape in the center console or in a book bag on the way out the door. The Davinci IQ also promises quick heat ups and a high-quality experience for all vapers when compared to the harsh hit of the water pipes of yesteryear.

Why Buy: adjustable airflow; reasonable price point; strong build quality; replaceable battery; and dual use, meaning its swappable between dry herb and concentrate

Arizer Solo 2 Vaporizer - Easiest to clean

Slick Vapes

Arizer is the best dry herb vaporizer for smoking flower. Where the picks above are great for flower and concentrates, the dual use design of the Arizer Solo 2 is built to be easy to clean. You can pull the glass mouthpiece and tube from the vape to soak in alcohol, which makes it easy to return the vaping experience to new after consistent use. With solid air path and the higher temperatures you want out of a portable vape, the Arizer Solo II beats an old bubbler or desktop vape any day.

Why Buy: lifetime warranty on the heating element, and a 2-Year warranty covering the vape device, excluding the replaceable battery; ease of use; hybrid heating, but mainly convection heating; comparable to the Firefly 2; multiple temperature settings

Plenty Vaporizer - Best for Liquids

Slick Vapes

The Storz & Bickel VOLCANO is a legendary desktop vaporizer. This handheld device from the famous vape brand is a sweet addition to the line. The Plenty comes with three screens, a liquid pad, cleaning brush, Storz & Bickel grinder, user's manual for ease of use, and more. It's lightweight and silent for discrete use, and has an adjustable temperature dial. It also looks pretty cool.

Why Buy: best portable vaporizer for liquid concentrates; trusted brand with a history of quality; curled vapor path; full suite of accessories included

G Pen Elite Vaporizer - Precision Temps

Slick Vapes

With precise temperature settings burnt herb is a thing of the past. The smell, the taste, no more. The G Pen Elite can hold 3/4 of a gram in its ceramic chamber, which, the brand says, is twice most portable vaporizers. But more than the size, it's that high-quality ceramic body that matters. Unlike stainless steel products, this crafty design keeps herb from catching fire.

Why Buy: USB charger; precision temperature settings; quality accessory options; durable ceramic design


How we evaluated portable dry herb vaporizers?

The dab, the bong, that dingy old water pipe smelling up the closet—those are the days of old.

Today the portable vape market is full of options that can be difficult to understand. Convection versus conduction, glass mouthpiece versus stainless steel, which is best?

To make this list we looked at price. We were willing to pay for quality and bluetooth connectivity, but a pocketable product should be affordable—no matter how precise they promise the preset temperature control is.

After price, we read a lot of customer takes on battery life and the accessories, including the charger that came with each product.

The difference between convection heating and conduction heating is interesting in sixth grade science—but more relevant today in the context of how quickly we can heat up material. And if we want it hot fast (conduction) or to not burn up (convection).

Brands are important. We started with brands with a track record. But when it comes down to it we're trying to vaporize marijuana or hemp flower, so portability, air flow, and ease of use were more important.

Conclusion

At 40% bioavailability (more or less), vaporizing flower an effective way to get a daily dose of your favorite flower. But smoking shouldn't be taken lightly. Make sure the product you're inhaling is worth the potential damage to your lungs. Like anything we put into our bodies, particularly something that can directly affect organs as important as our lungs, users should weigh the benefits and risks before buying a portable vaporizer.

Once you have decided vaping is right for you, think about ease of use, how easy a product is to clean, and how quickly it heats material. Maybe temperature control is important to you. Maybe you wand something super portable and discrete. either way, we hope this guide to the best dry herb vaporizers for sale online was helpful.

The excess carbon dioxide emitted by human activity since the start of the industrial revolution has already raised the Earth's temperature by more than one degree Celsius, increased the risk of extreme hurricanes and wildfires and killed off more than half of the corals in the Great Barrier Reef. But geologic history shows that the impacts of greenhouse gases could be much worse.
