Today is Feb 12, 2024. I watched the video talking about the climate change. During this time, I just passed three questions mentioned in the video.
First question: What is the climate change?
Climate change is about the heat being added to the Earth system. Human activities like burning fossil fuels, cutting down forests that have been standing for hundreds of thousands of years create carbon dioxide in the atmosphere. Carbon dioxide is a greenhouse gas. The more greenhouse gas you have in the atmosphere, the more of the sun's heat get trapped in the atmosphere and the warmer the surface gets and that's why it's called greenhouse effect.
2. What are greenhouse gases?
Greenhouse gases exist naturally in the atmosphere. If there's no greenhouse gases in the atmosphere, the world would be too cold for comfort. Greenhouse gases on their own are actually great. It helps to insulate the Earth. The problems we are facing now is the numerous of greenhouse gases being added to the Earth.
3. What are fossil fuels?
All of the systems that underpin our lives. So how we produce food to eat, how we create energy to heat our homes, how we create electricity to power our devices, how we fuel our cars. For the most part, historically, we burn fossil fuels to produce energy. Fossil fuels are essentially from plants and animals from millions of years ago. We burn fossil fuels to create heat and electricity and everything. But then we also produce carbon dioxide as a side effect.

Love this podcast! :) I like everything, the topic, how the interview goes, and the subtitles. I wish I had known it before, although I've been watching BBC but didn't explore this in the past. I have been listening to different podcasts, this one is the best! Wish we could have more of this informative topics! :) I'll keep this on my regular routine! 🙂🙂

What is the first and foremost step that industrial nations take towards climate change?

Winter frost patterns retreating from valleys to mountains in pakistan. Paddy and maize yields falling for hybrid seds. How to reverse it

[xbqhquc]

I am an electric engineering statement and I do believe that there is a permanent source for producing electricity❤

[rodmartin-nlns]

I will tell you what climate change is It is something to say when politicians want to change the subject they do it all time

[A.E.Anowar]

I just love this episode and topic on which the whole vidoes are talked.. There is a still hope to control the adverse effects of climate changes.

[shivakumarv]

Is electricitic cars and scooters cutting the cost of transportation to half in
Tropical countries?

[RovshanShodmonov-flhs]

This is true, we just need to adapted the life about the climate change.the cutting down trees along the forests is the most impact on climate change

[mopuribalu]

Sir, Are the power plants collapsing cooling towers ? nijama?

[natureexplorer]

I am not watching it for school. I am actually a nature lover and concerned about climate change.

Climate change is not "turbocharging weather events".
The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that severe weather events cannot be detected as increasing, nor attributed to human caused climate change:
Increased Flooding: not detected, no attribution.
Increased Meteorological Drought: not detected, no attribution.
Increased Hydrological Drought: not detected, no attribution.
Increased Tropical Cyclones: not detected, no attribution.
Increased Winter Storms: not detected, no attribution.
Increased Thunderstorms: not detected, no attribution.
Increased Hail: not detected, no attribution.
increased lightning: not detected, no attribution.
Increased Extreme Winds: not detected, no attribution.
There is no climate crisis.
The UN's IPCC AR6 report, chapter 11 'Weather and Climate Extreme Events in a Changing Climate' summarises the fact that certain severe weather events cannot be detected as increasing, nor attributed to human caused climate change:
Pages 1761 - 1765, Table 11.A.2 Synthesis table summarising assessments
Heavy Precipitation: 24 out of 45 global regions low confidence in observed trend (12 medium confidence), 43 out 45 low confidence in human attribution.
Agricultural Drought: 31 out of 45 global regions low confidence in observed trend
(14 medium confidence. No high confidence assessment). 42 out 45 low confidence in human attribution (3 medium, no high confidence).
Ecological Drought as above.
Hydrological Drought: 38 out of 45 global regions low confidence in observed trend.
43 out 45 low confidence in human attribution (2 medium confidence, no high confidence).
So the IPCC are saying we didn't cause droughts and we didn't make it rain. How surprising!
There is no objective observational evidence that we are living in a global 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.
How about some quotes from the UN's IPCC AR6?
"There is low confidence in the emergence of heavy precipitation and pluvial and river flood frequency in observations, despite trends that have been found in a few regions."
"There is low confidence in the emergence of drought frequency in observations, for any type of drought, in all regions."
"Observed mean surface wind speed trends are present in many areas, but the emergence of these trends from the interannual natural variability and their attribution to human-induced climate change remains of low confidence due to various factors such as changes in the type and exposure of recording instruments, and their relation to climate change is not established. . . The same limitation also holds for wind extremes (severe storms, tropical cyclones, sand and dust storms)."
There is no objective observational evidence that we are living through a global climate crisis. None.

The real reason for the changed climate is not Co 2.
There is a unique reason for this changing climate .

[tsheringdenkar]

Wats solution for climate change now???

[xychachiniyoyo]

*Are Israel and Palestine conflict & Russia and Ukraine conflict not responsible for increasing global warming ?* ( even little bit )

[hermanp.delacruz]

ITS MORE HARD TO LIVE WITHOUT IMPATHY BY OTHERS...CRUEL WORLD TO CRUEL WEATHER ISNT IT! "

[dennisnorton]

Of course back in the 19th century rivers & lakes use to freeze over in the winter & there were even makets held on the Thames & Matt Taylor of the BBC said it was caused by low sun activity for years but in the last 20 years there has been high activity by the sun, does any body not think that may have something to do with climate change? Of course there have also been over 2000 nuclear bomb test since the WW2 with over 500 emitted into the atmosphere. All of these things have made differences to the worlds climate & I sincerely believe that all that radiation has caused one in two people now getting cancer.

Maximum 2 children policy for every country would have an immediate positive impact on global warming, migrationresources, employment etc. But corporation likebbc of course wouldn't discuss the source of problem...We are human, we all consume and therefore have an impact on everything from A to Z. I don't take anyone who lectures me on global warming seriously without first addressing the issue with global over population.

Hey ppls, I'm 19 yrs old engaged in my studies but at the same time I am taking care of my mother nature by planting tress and looking after for it.
It's our job to save our planet, you ought to do
