Hi - welcome. This is a place to share videos related to my lukebennett13 project. I'm an Emeritus Fellow (previously an Associate Professor in the Department of the Natural & Built Environment) at Sheffield Hallam University in the UK.
I'm co-ordinator of Sheffield Hallam University's Space & Place Group. The Group is very fluid, interdisciplinary and playful. Our members include artists, social scientists, humanities and management studies academics. We come together in ever-shifting permutations for 3-4 events each year, often anchored around an annual theme, such as 'home comforts', 'haunts', 'politics of place', 'exploration'. We often create our events in collaboration with other groups and institutions.
For details of our forthcoming activities, or to suggest a collaboration, please either:
Email Luke at drlukebennett13@gmail.com and he’ll add you to our e-mailing list; or Follow Luke at @lukebennett13 on Twitter or via his blog at lukebennett13.wordpress.com
A classic example of academic myopia. The issue staring us all in our faces is HEAT, and the role of heat in melting global ice, the consequence of sea level rise, and the importance of melting ice in our global cooling system, particularly as we continue to burn fossil fuels and produce ever more heat energy. So, here are the facts, apparently missed in the over 2 hrs. of academic meandering: 1.2 trillion tons of global ice are melting annually (Copernicus), so 3.3 billion tons per day; the 321 million cubic miles of oceans into which that melt water flows are heating to 70 degF in mid-latitudes, and finally being evaporated into 1 trillion tons of water vapor (most potent GHG) every day. This is our planet's AC system, along with radiant loss back into space. So, what? C3S predicts that 2/3rds of the 5 million cubic miles of ice will have melted by 2,100, 76 yrs. hence, and that extrapolates to 2,138 for total loss of global ice, or 115yrs hence. Another source just predicted that 80% of Himalayan glaciers will have melted by 2,100, so all gone by 2.119, leaving south central Asian rivers bone dry. We continue to mindlessly burn 8 billion tons of coal a year, and 100 million barrels of oil a day, generating the bulk of global heat energy production: the equivalent of 13.3 Hiroshima yield nuclear bomb blasts per second (HpS) (ref-Eliot Jacobson), or 1,149,120 per day, where each releases 63 trillion BTUs into the environment. The average American, who can afford it, continues to drive, fly, or cruise off willy nilly burning 13.3 million barrels of oil per day. And, what a surprise (?), the global ice keeps melting at an astronomical rate, the oceans keep heating, and the skies are more filled with clouds of water vapor, as the rain/snow/hail rains down in floods. And, all the while, the "academics" measuring the myopic effects of the melting ice continue to ignore their secondary school physics: one pound of ice absorbs 144 BTUs of heat energy as it melts into water. So, 3.3 billion tons of ice absorbs...BTUs?
@@anthonymorris5084 Hard to refute an argument from someone so uninformed about basic climate science, including thermodynamics. We are just way, way too far apart in basic climate science knowledge to have an intelligent dialog, so goodbye.
It is to me a tragic situation that Greenland - in the pursuit of enabling so-called "green energy" (which is mostly not really "green") - that it will probably openup gigantic mines to go after all sorts of metals needed with huge and potentially devastating environmental consequences.
yes Lise, i ofteh think that the canadian policies of late should unite all the parties and encompass nuuksand become a global refuge as a sensible pact of evolution
best perspective of scale so far, 'muy goat herderfriends dads hereded goats 350 meters up there not to long ago", and i DO want to be that grain that tips the scales friend.
No friend, ...everyone knows what a TRILLION is,.... its alot. No One knows what a gigaton is it sounds like it comes from Space,... Target your audience Thye people that Know the difference you dont have to convince that its "Alot".
Climate change has been here for 4.6 Billion years. All Geologists know this. Even Historians know the little ice age and the medievil warm period happened. If everybody who ever they are looked at the bigger picture you would see there is no Climate problems at all.
Per the second presenter: Canada and Britain under ice 25,000 years ago. All melted. 400 feet of sea level rise. And the current models did not model it correctly. Things that make you go, "Hmm."
@@marcariotto1709 Imagine Canada and northern Europe under ice, and how much land changed to water after 400 feet of sea level rise. No humans involved. Now tell me again about maybe some low island archipelago that is at risk.
@chrimony All joking and acrimony aside. It is not just climate change or the cause of it that are huge problems for humanity. There is a poly crisis with 5 or more major threats to humanity. The thing is, if climate change and these other crises are human caused, humans can adjust and do better long-term through conservation. If you're correct, then it doesn't really matter long term. The saddest part is that conservation aligns with almost everything right-wing people claim to espouse. It's enshrines personal responsibility. It encourages savings and wise efficient use of resources, which decreases inputs while maximizing outputs. It respects others and their needs and looks to pay dividends forward to our inheritors rather than the current can kicking debt avoidance so bemoaned by the right. The only catch is that it's like facing the reconning of credit card debt. It sucks to go through it, but it's fantastic when you're no longer under the bank or whoevers thumb, and you can build a life, family and systems that are growing positively instead of constant pressure and tail chasing. The only ones who really suffer or don't benefit from conservation and long-range planning are people who live for today and the HWT, bankers, and dirt ball profiteers who really are just low life party should never end types anyway. There are tons and tons of small easily obtained savings and waste that we can go after before thinking about massive system changes. I'm not some pie in the sky dreamer greenie. I'm not some idealistic social commie wealth redistributor. I don't think capitalism is evil in itself. I view capitalism as any machine, but more so like an engine. There are very few places, including race tracks, where we will let unbridled power run unregulated and unchecked because it means death and mayhem will ensue. Only elitist capitalists benefit from unchecked, unregulated free markets because they are insulated from the detrimental effects. I'm well aware that total electrification is impossible and undesirable. I'm well aware that oil is an indispensable commodity that allows life for 6-7 billion people who would otherwise starve to death very quickly without it. These are all the more reasons that conservation, especially of oil, is a healthy long-term goal for everyone. Our national parks are a prime example of long-term vision that doesn't have or need a profit motive to create benefits. Ducks unlimited is another that actually creates immense profit side streams. Both do, actually. I'm old enough that I just barely remember the Ohio River burning. I grew up with orange coal creeks and black mountains all around me. Humans don't have to destroy everything through climate. We're doing a great job one little piece at a time, and you don't have to shut the world down to turn that around. It's all about achieving balance between individuals and the group. Swaying too far either way only creates friction that eventually leads to fighting and war, which once again benefits the super rich elitists the most. So, tying back to my opening statements. Conservation and long-term planning help everyone and the planet, including extreme capitalists (although not as grossly), while claiming it's all just natural breeds an F-it, there's no point worrying about it or even trying attitude. In short, there's nothing to be gained but short-term profit in your view even if you're correct. Good day to you!
