As a result, beef is five times more damaging to the climate than white meat, and 11 times more than wheat, rice and potatoes. Baby steps are fine. You don't have to never eat red meat again, just be conscious of it.

Spiders are threatened by climate change – and even the biggest arachnophobes should be worried

But again, if you want to play this on hard mode, going vegetarian makes a huge difference. In July, Science magazine published optimistic research saying climate change could be neutralized for around 20 years if we planted enough trees on all the unused land around the world. Since then, though, other scientists and experts have said that planting trees alone won't fix the problem. So while we sadly can't plant all of our problems away, planting a tree will still help. A tree can be expected to absorb around 28 pounds of carbon dioxide a year and around a metric ton during a year lifespan.

Every pound counts! If you've got nowhere to plant a tree, maybe swap Google for Ecosia. Eating fruits and vegetables is good for you, but consumption of out-of-season fruits and veggies can also be bad for the environment, even if not as damaging as red meat.

The challenging politics of climate change

Big supermarkets stock the same produce all year round but, as you know, fruit and vegetables are seasonal. There are two main ways sellers get around this: Import food from overseas, or pay local farmers who use huge amounts of water and electricity to grow them out of season. You can mitigate both of these contributors by finding out, with a quick Google search, what food is seasonal in your country or region. For instance, in Sydney, where I live, it's spring right now, which means pineapples, mandarins, asparagus and much more are very hot right now.

The annoying part can be finding a grocery store that you're sure buys its produce from local farmers. But once you do this recon, you'll end up with more environmentally friendly produce. Throwing away your food means wasting the carbon dioxide used to produce it. Not only that, but discarded food ends up in landfills where, due to it decomposing without the presence of oxygen , it causes emissions of methane into the atmosphere.

Waste less food and you'll buy less food, which is helpful for both Mother Nature and your wallet. But this is a harder sacrifice to make, since there are often no real alternatives to flight. We've put this last because this is the biggest sacrifice on the list, at least financially. Wind and solar energy are cheap and getting cheaper, but setting up the infrastructure required to funnel energy from the sun to your PlayStation can be expensive.

The size, shape and age of your roof can also be restrictive factors.

But you'll be a winner over time, since you'll save more and more money each year. Here's a guide for what you can expect to spend in the US. Originally published Oct.

We really may have just 11 years to save the climate

Belgium 4. Canada 6. Ireland 7. Estonia 8. Malta 9. Finland Norway Switzerland Australia Hong Kong Netherlands and Analysis of future emissions trajectories indicates that, left unchecked, human emissions of greenhouse gases GHG will increase several fold during the 21st century. Consequently, Australia's annual average temperatures are projected to increase 0.

Average precipitation in southwest and southeast Australia is projected to decline during this time period, while regions such as the northwest may experience increases in rainfall. Such changes in climate will have diverse implications for Australia's environment, economy, and public health. A technical report on climate change in Australia jointly published by Commonwealth Scientific and Industrial Research Organisation CSIRO and the Bureau of Meteorology provided climate change projections accounting for a number of variables, including temperature, rainfall, and others.

The report provided assessments of observed Australian climate changes and causes, and projections for and , under a range of emissions scenarios.

The Government of Australia acknowledges the impacts of changing climatic conditions, and its Department of Climate Change and Energy Efficiency has established the Australian Climate Change Science Program ACCSP , which aims to understand the causes, nature, timing, and consequences of climate change so as to inform the Australian response.

Firefighting officials are concerned that the effects of climate change will increase the frequency and intensity of bushfires under even a "low global warming" scenario. Globally, the World Meteorological Organization has claimed that extreme weather events are on the rise as a result of human interference in the climate system, [] and climate models indicate the potential for increases in extremes of temperature, precipitation, droughts, storms, and floods.

There are a number of issues that could cause a range of direct and indirect consequences to many regions of the world, including Australia. These include large-scale singularities — sudden, potentially disastrous changes in ecosystems brought on gradual changes. Coral reef ecosystems have a narrow temperature range, meaning that they can rapidly change from being a healthy system to being stressed, bleached, or at worst, eradicated.

Call to declare a climate emergency

Ecosystem changes in other parts of the world could also have serious consequences for climate change for the Australian continent. Evidence from carbon cycle modeling suggests that the deaths of forests in tropical regions might increase the net concentration of carbon dioxide in the atmosphere, by converting the terrestrial biosphere from a carbon sink to a source of CO 2.

Recently, scientists have expressed concern about the potential for climate change to destabilize the Greenland ice sheet and West Antarctic Ice Sheet. Such deterioration could cause significant environmental and economic consequences through regional climate shifts in Australia and elsewhere, resulting from change in the global ocean circulation. Immense quantities of ice are held in the ice sheets of West Antarctica and Greenland, jointly containing the equivalent of approximately 12 meters of sea-level rise.

Deterioration or breakdown of these ice sheets would lead to irreversible sea-level rise and coastal inundation across the globe. The CSIRO predicts that additional singularities caused by a temperature rise of between 2 and 3 degrees Celsius will be:. Projections for Australia's changing climate include: []. Australia has some of the world's most diverse ecosystems and natural habitats, and it may be this variety that makes them the Earth's most fragile and at-risk when exposed to climate change.

The Great Barrier Reef is a prime example. Over the past 20 years it has experienced unparalleled rates of bleaching. Small changes caused by global warming , such as a longer growing season, a more temperate climate and increased CO 2 concentrations, may benefit Australian crop agriculture and forestry in the short term. However, such benefits are unlikely to be sustained with increasingly severe effects of global warming. Changes in precipitation and consequent water management problems will further exacerbate Australia's current water availability and quality challenges, both for commercial and residential use.

Healthy and diverse vegetation is essential to river health and quality, and many of Australia's most important catchments are covered by native forest, maintaining a healthy ecosystem.

Climate change will affect growth, species composition and pest incursion of native species and in turn will profoundly affect water supply from these catchments. Increased re-afforestation in cleared catchments also has the prospect for water losses. The CSIRO predicts that the additional results in Australia of a temperature rise of between only 1 and 2 degrees Celsius will be: [].

Global warming could lead to substantial alterations in climate extremes, such as tropical cyclones, heat waves and severe precipitation events. This would degrade infrastructure and raise costs through intensified energy demands, maintenance for damaged transportation infrastructure, and disasters, such as coastal flooding. The CSIRO describes the additional impact on settlements and infrastructure for rises in temperature of only 1 to 2 degrees Celsius:. Climate change will have a higher impact on Australia's coastal communities, due to the concentration of population, commerce and industry.

Coleman, T. Proceedings of Living with Climate Change Conference. Canberra, 19 December. Tourism of coastal areas may also be affected by coastal inundation and beach erosion, as a result of sea level rise and storm events. At higher levels of warming, coastal impacts become more severe with higher storm winds and sea levels.

A report released in October by the Standing Committee on Climate Change, Water, Environment and the arts, studying the effects of a 1-metre sea level rise, possible within the next 30—60 years, concluded that around , properties around Australia, including 80, buildings, would be inundated. A 1-metre sea level rise would have massive impacts, not just on property and associated economic systems, but in displacement of human populations throughout the continent. Queensland is the state most at risk due to the presence of valuable beachfront housing.

The escarpment is cut by a number of very rugged gorges such as the Morialtta Gorge and Waterfall Gully.
