Suffer our children unless the world changes
The climate change situation is grim and it is young people who will wear the consequences.Most New Zealanders are not yet directly affected by the negative impacts of climate change – the full effects of the greenhouse gases now in the atmosphere won't be felt for another 30-40 years. However, make no mistake: the dire consequences of today's actions will be passed on to the future generation.
Intergenerational justice is the cry going up from young people around the globe. What's fair is for each generation to leave behind a world that is in a condition at least as good as when its members grew up. That makes the current generation the guardians of our future. It is their responsibility to preserve and protect the world so that we can enjoy the same glaciers, rainforests, abundance of food and level of health and wellbeing that our parents had the opportunity to experience.
The evidence around climate change is compelling. Over the last century, average temperatures have risen by 0.7C globally, and by 0.9C in New Zealand. We are witnessing massive reductions in alpine snow mass and significant retreats of many South Island glaciers and snowlines. Sea level has risen, on average, 17cm in the last 100 years. Nothing we do now can change a further one degree of warming by 2050 and, if business as usual continues, there may well be a rise of more than 4C by the end of the century.
We face the risk of damage to our native ecosystem, a decline in agricultural productivity and more frequent extreme weather events including catastrophic droughts in some areas and floods in others.
The link between climate change and human activity has been widely demonstrated. The level of atmospheric CO2 has risen continuously since the beginning of the industrial era. The emission of greenhouse gases from burning fossil fuels has altered the balance between incoming solar energy and outgoing thermal radiation.
We don't have much time to mitigate the situation before it's beyond our control.
Hydrogen Engine Technology - News
Fuel cells work by splitting hydrogen atoms into negative ions, electricity and positive ions that combine with oxygen to make water. The technology dates back to the beginning of the US space program, so why has it taken so long to come up with an
Hydrogen is best replacement fuel because it checks all the end-user convenience boxes liquid hydrocarbon fuels do, the only real problem is that the supply side of things hasn't been worked out - Honda already has the engine technology and has
The J-2X engine design leverages 50 years of experience in human spaceflight with state-of-the-art technology in design processes, materials and manufacturing to enable further human exploration. The J-2X is a liquid-oxygen/liquid-hydrogen fueled
We're not competing with other fuel cell companies, but with internal combustion engines. [Ours] is a disruptive technology to turbines in power generation.” AFC's is modular system based on 10 kilowatt-hour (kWh) 'blocks.' They're manufactured using
Nearly three-quarters of respondents said they'd be interested in some form of electric alternative by then, such as a hybrid, plug-in hybrid, pure-electric, or hydrogen-fuel-cell vehicle in the future. More people said they would consider
