With contributions from Skeptical Science, Blue & Green Tomorrow debunks a different climate change myth each day over the Christmas period.

We dispel the delusion that there are positives to come out of global warming.

The sceptic argument…

“Two thousand years of published human histories say that warm periods were good for people. It was the harsh, unstable Dark Ages and Little Ice Age that brought bigger storms, untimely frost, widespread famine and plagues of disease.”

(Dennis Avery).

What the science says…

Here’s a list of cause and effect relationships, showing that most climate change impacts will confer few or no benefits, but may do great harm at considerable cost.

Agriculture

While CO2 is essential for plant growth, all agriculture depends also on steady water supplies, and climate change is likely to disrupt those supplies through floods and droughts. It has been suggested that higher latitudes – Siberia, for example – may become productive due to global warming, but the soil in Arctic and bordering territories is very poor, and the amount of sunlight reaching the ground in summer will not change because it is governed by the tilt of the earth. Agriculture can also be disrupted by wildfires and changes in seasonal periodicity, which is already taking place, and changes to grasslands and water supplies could impact grazing and welfare of domestic livestock. Increased warming may also have a greater effect on countries whose climate is already near or at a temperature limit over which yields reduce or crops fail – in the tropics or sub-Sahara, for example.

Health

Warmer winters would mean fewer deaths, particularly among vulnerable groups like the aged. However, the same groups are also vulnerable to additional heat, and deaths attributable to heatwaves are expected to be approximately five times as great as winter deaths prevented. It is widely believed that warmer climes will encourage migration of disease-bearing insects like mosquitoes and malaria is already appearing in places it hasn’t been seen before.

Polar Melting

While the opening of a year-round ice free Arctic passage between the Atlantic and Pacific oceans would confer some commercial benefits, these are considerably outweighed by the negatives. Detrimental effects include loss of polar bear habitat and increased mobile ice hazards to shipping. The loss of ice albedo (the reflection of heat), causing the ocean to absorb more heat, is also a positive feedback; the warming waters increase glacier and Greenland ice cap melt, as well as raising the temperature of Arctic tundra, which then releases methane, a very potent greenhouse gas (methane is also released from the sea-bed, where it is trapped in ice-crystals called clathrates). Melting of the Antarctic ice shelves is predicted to add further to sea-level rise with no benefits accruing.

Ocean Acidification

A cause for considerable concern, there appear to be no benefits to the change in pH of the oceans. This process is caused by additional CO2 being absorbed in the water, and may have severe destabilising effects on the entire oceanic food-chain.

Melting Glaciers

The effects of glaciers melting are largely detrimental; the principle impact being that many millions of people (one-sixth of the world’s population) depend on fresh water supplied each year by natural spring melt and regrowth cycles and those water supplies – drinking water, agriculture – may fail.

Sea Level Rise

Many parts of the world are low-lying and will be severely affected by modest sea rises. Rice paddies are being inundated with salt water, which destroys the crops. Seawater is contaminating rivers as it mixes with fresh water further upstream, and aquifers are becoming polluted. Given that the IPCC did not include melt-water from the Greenland and Antarctic ice-caps due to uncertainties at that time, estimates of sea-level rise are feared to considerably underestimate the scale of the problem. There are no proposed benefits to sea-level rise.

Environmental

Positive effects of climate change may include greener rainforests and enhanced plant growth in the Amazon, increased vegetation in northern latitudes and possible increases in plankton biomass in some parts of the ocean. Negative responses may include further growth of oxygen poor ocean zones, contamination or exhaustion of fresh water, increased incidence of natural fires, extensive vegetation die-off due to droughts, increased risk of coral extinction, decline in global phytoplankton, changes in migration patterns of birds and animals, changes in seasonal periodicity, disruption to food chains and species loss.

Economic

The economic impacts of climate change may be catastrophic, while there have been very few benefits projected at all. The Stern report made clear the overall pattern of economic distress, and while the specific numbers may be contested, the costs of climate change were far in excess of the costs of preventing it. Certain scenarios projected in the IPCC AR4 report would witness massive migration as low-lying countries were flooded. Disruptions to global trade, transport, energy supplies and labour markets, banking and finance, investment and insurance, would all wreak havoc on the stability of both developed and developing nations. Markets would endure increased volatility and institutional investors such as pension funds and insurance companies would experience considerable difficulty.
Developing countries, some of which are already embroiled in military conflict, may be drawn into larger and more protracted disputes over water, energy supplies or food, all of which may disrupt economic growth at a time when developing countries are beset by more egregious manifestations of climate change. It is widely accepted that the detrimental effects of climate change will be visited largely on the countries least equipped to adapt, socially or economically.

As a society we are getting much better at taking our obligations to the world and environment around us more seriously. This is undoubtedly a good thing! The effects of climate change are beginning to manifest across the world, and this is turning the issue from an abstract threat into a very real danger. Trying to introduce some greener, more eco-friendly practices into your life isn’t just a great way of doing something beneficial for society and the world around you. It is a wonderful way of engaging positively with the world and carries with it numerous psychological benefits.

Being a greener, more ecologically friendly person doesn’t require any dramatic life changes. Breaking or making a few small habits is all it takes to make your life a greener one. In this article we look at one of the easiest, yet most effective green practices to get into: reusing everyday items.

Jars and Containers

Glass and metal are widely recycled, and recycling is a good thing! However, consider whether any containers you buy, whether it’s a tub of ice cream or a jar of coffee, can be washed out and reused for something else. Mason jars, for example, can be used to store homemade pasta sauce and can be washed for future use. Once you start thinking about it, you will find endless opportunities to reuse your old containers.

Soda Bottles

An ice-cold soda is a wonderful treat on a hot day, but buying soda can get expensive, and the manufacturing and distribution of the drinks themselves isn’t great for the environment. However, by holding on to your old soda bottles and repurposing them as water bottles, you can save money on drinks, or use them to measure out water for your garden.

Plastic Bags

Most of the time groceries come in paper bags, which are better for the environment than the plastic alternatives, but they are less durable and thus harder to reuse. Whenever the store places your items in a plastic bag, hang onto it so you can reuse the bags again. If you want to take it one step further, consider looking into buying some personalized recycled bags. These bags are designed to last for a long time and are made of recycled materials. They look striking and unique, they’ll turn heads, and maybe even attitudes!

Seeds

If you’re a keen gardener, then you will already probably know how to reseed your plants in order to ensure a fresh crop after each plant’s lifecycle. If you have space in your garden, or haven’t yet tried your hand at gardening, then consider planting a small vegetable plot. Growing your own veggies means that you’ll be helping to cut back on the emissions generated by their transport and production. The best part about growing your own food in this way is that, by harvesting properly and saving the seeds, you can be set up with fresh vegetables for life!

Reusing and recycling common household items is an easy way to make your world a little bit greener. Once you start looking for these opportunities you’ll realize that they’re everywhere!

The sudden interest in green business is very encouraging. According to recent reports, 42% of all companies have rated sustainability as an important element of their business. Unfortunately, the focus on sustainability will only last if companies can find ways to use it to boost their ROI.

Many businesses get so caught up in being socially conscious that they hope the financial aspect of it takes care of itself. The good news is that there are plenty of ways to go green and boost your net income at the same time.

Here are some important mistakes that you will want to avoid.

Only implementing sustainability on micro-scale

The biggest reason that brands are going green is to improve their optics with their customers. Too many businesses are making very minor changes, such as processing paperwork online and calling themselves green.

Customers have become wary of these types of companies. If you want to earn their business, you are going to need to go all the way. Bring in a green business consultant and make every feasible change to demonstrate that you are a green organization from top to bottom.

Not prioritizing investments by long-term ROI

It isn’t realistic to build an entirely green organization overnight. You will need to allocate your capital wisely.

Before investing in any green assets or services, you should always conduct a long-term cost benefit analysis. The initial investment for some green services may be over $20,000. If they don’t shave your cost by at least $3,000 a year, they probably aren’t worth the investment.

Determine which green investments will have the best pay off over the next 10 years. Make these investments before anything else. Then compare your options within each of those categories.

Implementing green changes without a plan

Effective, long-term planning is the key to business success. This principle needs to be applied to green organizations as well.

Before implementing a green strategy, you must answer the following questions:

  • How will I communicate my green business philosophy to my customers?
  • How will running a green business affect my revenue stream?
  • How will adopting green business strategies change my monthly expenses? Will they increase or decrease them?
  • How will my company finance green upgrades and other investments?

The biggest mistake that too many green businesses make is being overly optimistic with these forecasts. Take the time to collect objective data and make your decisions accordingly. This will help you run a much more profitable green business.

Not considering the benefits of green printing

Too many companies believe that going paperless is the only way to run a green organization. Unfortunately, going 100% paperless it’s not feasible for most companies.

Rather than aim for an unrealistic goal, consider the option of using a more environmentally friendly printer. It won’t be perfect, but it will be better than the alternative.

According to experts from Doranix, environmental printers have several benefits:

  • They can process paper that has been completely recycled.
  • They consume less energy than traditional printers.
  • They use ink that is more environmentally friendly.

You want to take a look at different green printers and compare them. You’ll find that some will meet your needs as a green business.

Poorly communicating your green business strategy to customers

Brand positioning doesn’t happen on its own. If you want to run a successful green business, you must communicate your message to customers as clearly as possible. You must also avoid the appearance that you are patronizing them.

The best approach is to be clear when you were first making the change. I’ll make an announcement about your company‘s commitment to sustainability.

You also want to reinforce this message overtime by using green labels on all of your products. You don’t have to be blatant with your messaging at this stage. Simply provide a small, daily reminder on your products and invoices.

Finally, it is a good idea to participate in green business seminars and other events. If your community has a local Green Chamber of Commerce, you should consider joining as well.
