‘It’s happening, it’s now,’ says U.S. government report on climate change

On Friday, the federal government released its most dramatic report yet on the effects of climate change. According to scientists, the country is already experiencing serious consequences from rising global temperatures, including more frequent and severe storms, fires and flooding. John Yang talks to Michael Oppenheimer, professor of geosciences and international affairs at Princeton University.

‘It’s happening, it’s now,’ says U.S. government report on climate change

Climate change is controversial and the subject of huge debate. Complex climate models based on maths helps us understand. How do these models work?

A lecture by Chris Budd OBE, Gresham Professor of Geometry 13 November 2018

https://www.gresham.ac.uk/lectures-and-events/mathematics-climate-change

Climate change is important, controversial, and the subject of huge debate. Much of our understanding of the future climate comes from the use of complex climate models based on mathematical and physical ideas.

In this talk, Professor Budd will describe how these models work and the assumptions that go into them. He will discuss how reliable our predictions of climate change are, and show how mathematicians can give us insights into both past and future.

The Mathematics of Climate Change

  1. Okay let's bookmark this lecture. Current prediction is that 30 years from now that was 2018 when this video was published that all Arctic sea ice will be gone. That's going to be 2048. If by 2048 that doesn't occur are we going to get an apology for climate alarmism? I doubt it.

  2. What a load of presumptuous garbage. "'wider tree rings = warmer temps''? nonsense. Water is by far the most limiting factor.Hocky stick graphs showing cooler MWP? nonsense. It was warmer during the MWP and their are countless papers showing it.

  3. This is what happens when you have a mathematician (Professor of Geometry) who tries to skim over his selective and discredited data to foist his views on the rest of us.
    Michael Mann's "hockey stick" graph has been proven to be incorrect following his failed attempt to sue Professor Tim Ball when Mann was forced by Court disclosure to reveal he had omitted data in his possession in constructing his "hockey stick" graph.
    The arctic ice diagrams are also incorrect. Refer to Professor Fred Goldberg's video on arctic ice.

  4. Good God , what's it like to live in this climate change ignorance…..The best thing for climate change is to burn old Tires,,,,Man , I love the smell of rubber burning in the morning..

  5. We can all rest in the knowledge that thousands of years after the human parasites have been eradicated from the planet that our first toothbrushes will still be here!

  6. At 1.42 into this video the first slide (Earth System Model) shows all these overlapping circles of criteria to consider when attempting to calculate Changes in Climate.
    There is one HUGE omission this model. Where the HELL is the Solar Output measurements? So WTH, science is ignoring the BIGGEST factor in temperatures on Earth?
    At 9:12 in the video the NASA Graph shown shows that the Global Temp Mean has been increasing (no dips in temp) since about 1969ish. THIS IS A LIE! 
    NASA, NOAA and IPCC have been caught tampering with the temperature history records to make this Fake Graph possible! In the 1970's scientists were talking about the current cooling trend could be signaling another Mini-Ice Age as temps were going down. Where is the the "Pause" in temps where it DID NOT get warmer for 16 years? From about 1998 to 2014 the original records (before NASA, NOAA and IPCC changed this data) show no increase in Global Temps.

    Flooding, hurricanes, tornados, drought have nothing to do with Global Warming. We've ALWAYS had extreme weather, it's part of life on planet Earth. The Sun & Earth's magnetic field drive the weather, NOT the number of SUV's on the freeway.

    Our planet has a MOLTEN CORE…… how come nobody really considers that under sea volcanic activity can heat the oceans? I would think that Super Heated Magma causes more heating of ocean water than CO2, as CO2 only comprises 0.054% of our atmosphere.

  7. There is no dispute about climate change, it's going on since time began. FACT. When they earth heats due to the Sun's natural cycle, the oceans release CO2. FACT. CO2 IS NECESSARY FOR LIFE ON THE PLANET. FACT.PLANTS NEED IT TO PRODUCE OXYGEN WHICH WE NEED. FACT. CO2 IS NOT RESPONSIBLE FOR THE RISE IN TEMPERATURE, THE SUN IS. FACT. CARBON TAX IS FRAUD. FACT. WAKE UP PEOPLE YOU ARE BEING LIED TO AGAIN.

  8. We're approximately 33 -34 months away from "The Great Starvation" – Spring 2022. Followed by our
    EXTINCTION by 2026. Of course, those driven by GREED'S needs for "MORE", will want to scream,
    Lie & Deny. Unfortunately: NATURE DOESN'T GIVE A DAMN! And we're S-C-R-E-W-E-D! Period.

  9. CO2 causes mild warming and a large increase in plant growth. It is an immense benefit to the planet, and we should produce more.

  10. Bunch of data opposite to other areas of the world. Makes fatal error of thinking mankind has any sort of control over climate. Climate will as climate does so enjoy the weather along the journey and make adjustments like all the other creatures on the planet. I hear lots of 'ifs' and 'buts' and here we go the devil C02 and not one word about the overall greening of the earth….because of it?…we won't mention that inconvenient fact. We are still coming out of the Little Ice Age and in the looonger time frame this is a pimple on the graph. Arctic sea ice model should have an overlay of Antarctic sea ice levels as they generally run opposite to one another and again in a cyclical fashion.The climate IS actually cooling slightly…right on cue? as of 2019.

  11. I wonder if people understand the tipping points are like …you tease the tiger behind a fence, with a stick.
    But then I remove the fence.
    Methane is the gas that should scare you, since when it's released, you can do whatever to the industrial pollution or car's emission, but that tiger will be difficult to put back behind the fence.
    That's why the level around + 1 to 2 degrees Celsius, increased average temperature is so important.
    Beyond that…it's a run away greenhouse you should worry about.
    The actual number is not exact, but the actual event…release of Methane, is a tipping point.

  12. The salient point arrives @1.27 for those wondering if climate models should be used as FACT to construct global policy WHICH OF COURSE THEY HAVE

    "CLIMATE MODELLING IS REALLY HARD, REALLY UNCERTAIN AND WE LACK MUCH OF THE DATA"

    Which ties in nicely with the IPCC conclusion:

    "𝐰𝐞 𝐬𝐡𝐨𝐮𝐥𝐝 𝐫𝐞𝐜𝐨𝐠𝐧𝐢𝐬𝐞 𝐭𝐡𝐚𝐭 𝐰𝐞 𝐚𝐫𝐞 𝐝𝐞𝐚𝐥𝐢𝐧𝐠 𝐰𝐢𝐭𝐡 𝐚 𝐜𝐨𝐮𝐩𝐥𝐞𝐝 𝐧𝐨𝐧𝐥𝐢𝐧𝐞𝐚𝐫 𝐜𝐡𝐚𝐨𝐭𝐢𝐜 𝐬𝐲𝐬𝐭𝐞𝐦 𝐚𝐧𝐝 𝐭𝐡𝐞𝐫𝐞𝐟𝐨𝐫𝐞 𝐭𝐡𝐚𝐭 𝐭𝐡𝐞 𝐥𝐨𝐧𝐠 𝐭𝐞𝐫𝐦 𝐩𝐫𝐞𝐝𝐢𝐜𝐭𝐢𝐨𝐧 𝐨𝐟 𝐟𝐮𝐭𝐮𝐫𝐞 𝐜𝐥𝐢𝐦𝐚𝐭𝐞 𝐬𝐭𝐚𝐭𝐞𝐬 𝐢𝐬 𝐧𝐨𝐭 𝐩𝐨𝐬𝐬𝐢𝐛𝐥𝐞"

    In other words climate models are little more than casting the runes but a nice talking point at soirees in London, Paris, New York and other expensive shopping cities

    How this spoofery has reached the level of a religion is mind blowing

  13. Update the data… climate has flattened out… prof Happer phd explains why carbon is not the problem and climate models are seriously flawed
