Climate Change Explained

A straightforward explanation of Climate Change: the heat from human emissions is roughly equal to exploding 400,000 Hiroshima atomic bombs every day. Historically, every time carbon dioxide levels increase in Earth’s atmosphere, the average surface temperature increases, ice melts, and the seas rise.

  1. Why doesn’t anyone do anything? Everyone is always so worried yet nothing is done to stop the horrible chaos going on!

  2. Most men in the US and Europe could be infertile by 2050, according to a new study. … Sperm count in men from North America, Europe, Australia and New Zealand declined by 50-60% between 1973 and 2011, according to a new study from the Hebrew University of Jerusalem.Infertility is becoming a public health issue in Europe. Declining birth rates over the past 50 years mean that Europe is only producing 1.6 children per woman – hardly satisfactory to compete on the global stage against increasing populations of fit and able youth from the emerging economies of India and Africa and South America.A prominent reason for reduced fertility is the age-related decline in the number and quality of eggs as women in all European countries wait longer to have their first birth.Mass infertility is the 'logical conclusion' to the current patterns, according to one expert. "If the data on sperm counts is extrapolated to its logical conclusion,European men will have little or no reproductive capacity from 2060 onward," wrote Chris Barratt, Professor of Reproductive Medicine at the University of Dundee Europe Infertility testing and treatment market generated a revenue of $5874 million in 2016 and is anticipated to contribute $9874 million by 2025, growing at a CAGR of 6.01%. Europe has the largest market share of In-vitro fertilization market. Variation in skin color is the most noticeable of human polymorphisms. As visually dominant mammals, we readily notice differences in skin color in each other. As primates who uniquely use language to create categories, we readily give names to these differences. Since the mid-18th century, skin color has been the single most important physical trait used to define human groups. The prevalence of skin cancers is highest in lightly pigmented people who experience chronic or intense episodic exposures to strong UVR in places far from their ancestral homelands (MacKie et al., 2009). Skin cancers are mostly a consequence of modern human migrations and resulting mismatches between skin pigmentation and geography or lifestyle.dark skin pigmentation in humans had evolved primarily to prevent reduction of fertility due to the photolysis of folate present in cutaneous blood vessels (Jablonski and Chaplin, 2000). We presented evidence that folate depletion by UVR would precipitate folate deficiencies that would, in turn, lead to potentially fatal birth defects such as neural tube defects (NTDs). Dark skin pigmentation in humans evolved primarily to prevent reduction of fertility due to the photolysis of folate present in cutaneous blood vessels and destruction of DNA (Jablonski and Chaplin, 2000).Folate is important especially in rapidly dividing cells, such as those of the embryo and seminiferous tubules. Thus folate deficiencies caused by UVR would potentially affect both female and male fertility. Low folate levels cause derangements of folate-mediated 1-carbon metabolism that lead to serious diseases and birth defects. Folate deficiencies cause faulty DNA replication due to strand breaks caused by misincorporation of excessive uracil into DNA (Han et al., 2007; Stover, 2009). Studies from Africa have demonstrated that black people have higher vitamin B12 (cobalamin) levels than do white people. The dark skin of humans naturally arose because women who were darker skinned carried more normal fetuses to term than those who were light skinned. In dark skinned populations the MC1R locus is extremely conserved, suggesting powerful selective constraints which prevent sequence variation. No matter the phylogenetic relationships between dark skinned populations there is a consensus sequence which seems to have been selected for deep in the human past which remains the norm across these groups (i.e., though Melanesians and Africans are both very distantly related their dark skin is the end product of the same genetic architecture). But counterbalancing the need to block sunlight due to reduction in folate levels is the fact that vitamin D synthesis requires a minimum level of radiation to be catalyzed. Reduced vitamin D levels in caucasians not only result in bone deformations (i.e., rickets), but a heightened sensitivity to a host of diseases.

  3. Pure propaganda. CO2 only comprises 0.04% of the atmosphere and has a specific gravity that is heavier than oxygen and nitrogen so its impossible for it to rise in the atmosphere. End of discussion.

  4. think that making a video about conserving and lowering carbon footprint also probably made more carbon dioxide go into the air. Burning fossil fuels to make electrical energy to edit and research this.

  5. It can be safely assumed that homosexuality is the primary cause for the recent climate change issues, ever since the gay appeared on earth, there has been a spike in heat. This is because homosexuals emit more carbon dioxide into the environment and actually produce 42 different greenhouse gases by simply existing. During my trip to the 6th dimension, I discovered a man by the name of Niklas Vuranda. Vuranda was a gay man who showed me the ways of the gay. Vuranda was able to emit methane gas, sulfur hexafluoride, carbon tetrachloride and many more. This is an extreme danger to our planet, and even Vuranda told me to eliminate the gay from earth before it is too late.

  6. Climate change hoaxers! Humans are making the planet warmer? What are we causing next? Next thing you know they will be telling us were causing a zombie apocalypse.

  7. Thank you. “… there does exist at present a striking degree of agreement among experts in relevant fields about the cause and impact of climate change,..” “Sound scientific results, obtained through the employment of sound scientific methods, produce knowledge that can be acted upon …” ~ Universal House of Justice, Baha'i Faith

  8. Our planets climate has always changed, ever since it had a climate. There have been times far hotter and far colder than now. Mankind's impact on the climate is absolutely tiny and probably zero.
