Honestly, i liked the panel and the talk in itself, and i think that actor(idk her name) doesn't know shii.
Hi Nikhil,
I am a chemistry graduate and watched your conversations regarding climate change. I have noticed that Why CO2 sustains more longer period than other gas molecules.
The reason is that breaking CO2 molecules is not easy, because O=C=O bond breaking needs more energy than CH4 (C-H bond).
Hope you understand.
Thanks!
Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.
Extinction rates (1500-2009) peaked around 1900 at 50 per decade. Extinction rates have declined dramatically to around 4 to per decade in the 2000s. So the extinction rate is very low: 900 known lost species for 2.1 million known species in 500 years (IUCN), so from observations there are an average of slightly less than 2 species lost every year. Out of a known species total of over 2 million. That gives an annual percentage loss of less than 0.0001%. That's background extinction. At that frequency it will take over 930,000 years to reach 80% extinction of species experienced at the K-T boundary that saw the extinction of the dinosaurs. Of course, extinction is a natural part of the evolution of life on this planet with the average lifespan of a species thought to be about 1 million years (cf 930,000). It is estimated that 99.9% of all plant and animal species that have existed have gone extinct. It should also be noted that no taxonomic families have become extinct in the last 500 years. In fact marine diversity at the taxonomic level of families is the highest it has ever been in the Earth's long history (see Sepkoski Curve). In a review of 16,009 species, most populations (85%) did not show significant trends in abundance, and those that did were balanced between winners (8%) and losers (7%) (Dornelas et al, 2019). There have been only 9 species of continental birds and mammals confirmed extinct since 1500 (Loehle, 2011). No global marine animals have become extinct in the past 50 years (McCauley et, 2015 using IUCN data).
There is no climate crisis.
The UN's IPCC AR6, chapter 12 "Climate Change Information for Regional Impact and for Risk Assessment", section 12.5.2, table 12.12 confirms there is a lack of evidence or no signal that the following have changed:
Air Pollution Weather (temperature inversions),
Aridity,
Avalanche (snow),
Average precipitation,
Average Wind Speed,
Coastal Flood,
Agricultural drought,
Hydrological drought,
Erosion of Coastlines,
Fire Weather (hot and windy),
Flooding From Heavy Rain (pluvial floods),
Frost,
Hail,
Heavy Rain,
Heavy Snowfall and Ice Storms,
Landslides,
Marine Heatwaves,
Ocean Acidity,
Radiation at the Earth’s Surface,
River/Lake Floods,
Sand and Dust Storms,
Sea Level,
Severe Wind Storms,
Snow, Glacier, and Ice Sheets,
Tropical Cyclones.
If they haven't changed, you cannot attribute them to human activities. There is no climate crisis.
2023 was not the hottest year over large parts of the globe. Asia, Europe, U.S., Oceania, East N. Pacific Region, Hawaiian Region, Arctic, and the Antarctic all enjoyed their highest regional average temperature anomaly in previous years according to data released by NOAA.
Even if there is radical climate change (and that is a very, very big 'if') with the manifestation of numerous tipping points (including permafrost thaw, ocean hydrates dissociation, Arctic sea ice loss, rainforest dieback, polar ice sheet loss, AMOC slowdown, and Indian monsoon variability) the disruption to economic growth and well-being will be minimal. The world's economy will continue to grow making everyone much richer. By 2050 world mean consumption per capita should be $29,100 with tipping points or $29,300 without tipping points - barely noticeable. Apart from it being approximately double what it is now. By 2100 world mean consumption per capita should $71,000 with or without tipping points (Dietz et al, 2021).
This is the most fortunate time to be alive in the whole of history.
All that bro can think of is economics
@explorer29110 It's not that, it's that a little knowledge is dangerous. These people don't understand what they are talking about but they are trying to appear intelligent. Take the comments on ice core data. The correlation between temperature and CO2 if examined closely shows CO2 followed temperature with a lag of about 800 years at the transition from the last ice age to the current interglacial. I.e. the ice core evidence for Pleistocene/Holocene shows temperature rise caused CO2 to rise not the other way around probably due to outgassing from a warmer ocean. In fact, it gets more complicated, when comparing temperature data from Greenland for the Holocene (GISP 2) with CO2 (EPICA ice dome c) the correlation from about 3,500 years ago onwards appears to be negative. The temperature fell first, then CO2 went up.
These individuals are pseudo-intellectuals.
