isn't global warming showing it's signs in the last couple of days?

Answer 1

Yes and no. Global warming is real, and this should not surprize us, but this si not evidence for it. The evidence is below.

CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.

Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest, and 2006 is shaping up to maybe break that record.
(see links below)

How's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.

There has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.

Yes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up.

Just to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.

Answer 2

there's no way anyone can be sure that this is or is not an effect of global warming (although there seem to be a lot of people that are categorically denying it without any evidence).

on a side note, carbon dioxide is definitely the most benign gas we could be spewing into the air (other than N2) and the fact that we could see even ITS detrimental effects shows how much we're generating. a little CO2 wouldn't make any difference, but this much of anything is going to have an impact. can you imagine if a car's natural exhaust were hydrogen sulfide (rotten egg smell) instead? you might not want to leave your house if that were the case.

what are you doing about the problem?

Answer 3

Global warming is showing signs this last decade, but officials from most of the G8 countries and others are trying to act like and emu, and hide its head in the sand.
For them there is no hunger in the world, there is no thirst, and there is no global warming.
Abnormalities in the weather, heat, rains, are not comparable to any written history, so either it is a global warming produces by last two modern centurys with hyper carbon fuel consumption, hyper methane,so2,co2, dumping in the atmosphere, or this is a periodic cycle that happens every few thousend years, only that we do not have a written history so old.
Be prepared, it will be worse. France has last year seen so many deaths of elderly by heat , this year they are more prepared, they have more death sacks.

Answer 4

Not necessarily. I am personally an advocate for the possibility that humans are causing the average temperature of Earth to climb. However, short runs (heat waves) cannot and shouldn't be used as evidence of global warming. Their increasing (if and when the evidence come around) frequency should be. Also, 'Global Warming' is defined as in increase in the temperature in a climatological sense (over a long period of time 20+ years).

Answer 5

Perhaps. But don't try to do science based on anecdotal information. A few days prove or even indicate nothing.

Anyway, how are the temperatures in the southern hemisphere? Are they hotter too?

If people don't stop politicizing global warming it will never be resolved. Both sides are guilty.

Answer 6

um...global warming is a long-term, secular trend, so I don't think we can point to a week or two in the history of the earth to prove definitively that the earth is getting hotter.

I could have stated the opposite this past winter when we in Ohio were freezing our balls off for a few days.

Answer 7

Nope. The northern hemisphere's closer orientation to the sun has been showing it's signs for the last couple of days. In decades past this was often referred to as "summertime."

Answer 8

Nope. It's called summer, not global warming

Answer 9

Yes, because we should definately try to gauge long-term planetary climate changes with a few days worth of annecdotal evidence from a handful of regions.

Answer 10

Yes isn't the weather Crazy--- sign of end times are near...
