What are some signs that climate change/global warming is occurring now?

Answer 1

The melting icebergs, the destructive hurricanes, tsunamis, earthquakes and other natural disaster's. Also the hotter summers. The UV rays that are so much powerful and dangerous.

Answer 2

There is no solid evidence to prove that global warming is occurring or that it is being caused by humans. The scientific community accepts that the earth is over 5 billion years old and that the last ice age occurred like 11000 years ago. We have only been able to monitor the atmosphere with some accuracy for about .000000025% of the time the earth has existed (for those of you who don't know that is not long enough to establish a baseline or trend). We know that the temperatures have fluctuated over time, hoverer climate change is not the end of the world that we make it out to be. The sky is falling, the sky is falling, give me a break, it's been falling for 5 billion years. There is no reason to panic about it now. Even if the sky was falling (global warming) we wouldn't be able to tell for like 1000 years. Where do you see humans in 1000 years?

Answer 3

We have been measuring changes in earth's atmosphere for several decades. We have also measured increases in atmospheric carbon dioxide.

We have also measured the amount of carbon dioxide (depleted) pumped into the atmosphere by volcanoes. Volcanoes have existed throughout geologic history--billions of years. Volcanic activity is no greater now than in past ages.

We have also measured how much carbon we have reintroduced into the atmosphere from mining fossil fuels. These production records are readily available. And, monitoring stations detail seasonal fluctuations in CO2. The present level is twice what it was 50 years ago, when monitoring first began, and we know the extent to which we are responsible for this change.

Over 2000 scientists authored a report on climate change submitted to the UN. They conclude about 80% of the change is the result of human activity, and 20% is natural (orbital cycles, solar activity, and other natural effects).

If we take concerted effort, it is possible we might slow the inevitable change down a little bit. But that appears less and less likely as time goes on. It is like a smoker with emphysema insisting that cigarettes improve his ability to breath.

Answer 4

The most obvious sign is that temperatures are rising faster now than has ever been known before, even taking into account the extremely fast rise in temperatures that brought about the most recent glacial retreat (what many people refer to as the end of the last ice age).

100 years ago to average global temperature was 13.71°, it's now risen to 14.53°C. This is many, many times faster than has ever before been known. Contrary to a previous answer we have extremely accurate temperature records dating back to the mid 1600's, accurate records dating back over half a million years and reasonably accurate records dating back over half a billion years. Any further back and it's not possible to obtain reliable info as the only life on earth was single celled organisms (we need oxygen isotopes to obtain temp info).

A few of the effects of rising temperatures include...
> More rain globally but less rain in some places
> A probable increase in the number of storms and their intensity (GW isn't necesserily the only reason for the 80% increase in the last 30 years)
> Similarly huricanes and tornadoes occuring over a larger area.
> Heavier rains and droughts in turn lead to soil erosion, famine, drought etc.
> Desertification due to changing climate patterns.
> Rising sea levels resulting in the loss of agricultural land
> Rising sea levels threatening coastal towns and cities
> Melting permafrost resulting in the creation of agricultureal land
> Melting of the Polar ice caps (note that Arctic melting doesn't affect sea levels because the ice is floating and displaces it's own mass of water, Greenland and Antarctica aren't floating and any melting here adds to the seas ond oceans).
> Rising temperatures of the seas and oceans. This cuases expansion which leads to rising sea levels.
> Population due to the above. Already many island communities have been displaced.
> Acidification of the world's seas and oceans which affects corals and plankton and so has a knock on effect on the marine food chain.
> The greening of parts of Antarctica which now have grass growing on them.
> Migration further from Equatorial regions with the annual animal and bird migration having moved several km towards the Polar regions, hundreds of km in the case of butterflies.
> Earlier springs, animals are appearing earlier each year and plants and flowers are blooming earlier in the season.
> Glacial retreat faster now than has ever before been known.

There's lots more, I've just listed a few. You can find more details and citations for all of the above on a webpage I've created here - http://profend.com/global-warming/pages/effects.html

Answer 5

The storm that just occured in the Northeast. Global warming causes redistrabution of moisture so that when storms happen they dump lot more rain or snow in a short amount of time. It rained about 8 inches in the Northeast on Monday, there's tons of flooding!

Answer 6

well there is no global waring the ice thats melting is going through a natral proses its breaking off in chunks melting then re freasing again if it were just melting couse globalwarming it would melt simalar to a ice cube left out in a glas see just whater coming of not breaking peaces of ise you know the thing the titantic hit it was a natral part of the prosses i just explaned

Answer 7

lol, There aren't any. Only speculation and conjecture. No one knows if its human interferance or just normal cycle the earth goes through. You can site glaciers melting, but then you need to also look at the ones that are building.....You can site droughts in normally fertile valleys, but you must also see that at one time even Ethiopia wasn't a desert....do you see the problem here?

Answer 8

Just wait until the summer.. you'll feel the signs
