The potential consequences of climate change are great and the actions
taken over the next few decades will determine human influences on the climate for centuries.
Not exact matches
The idea did not
take hold in Europe, but it made its way to the U.S.
over the
next few decades.
Over the
next few decades, a revolution began to
take shape.
These
next - generation «massively - parallel» sequencers can achieve in just a
few days what once
took over a
decade to accomplish.
I can understand that approaching equilibrium
takes a long, long time, while TCR gives a better measure of what will happen
over the
next few decades (and that technology and society may be very different in 200 years time); but on the other hand, I thought nations had agreed to try to limit global warming to less than 2 degrees C overall, and not just to limit it to less than 2 degrees C by 2100.
My father is somewhat of a climate «sceptic» and insists that the prediction of 0.3 C cooling is based only on solar irradiance and does not
take into account increased cloud cover caused by low sun activity (he beleives that we are going to be facing extreme global cooling
over the
next few decades).
CO2 is
taken up in higher latitudes, mostly in the Southern Ocean, but while the uptake rate is a non-linear function of the chemistry, ocean biology and circulation, it isn't going to «saturate» any time soon (though it may slow
over the
next few decades).
Because natural gas is a considerably more expensive fuel than coal, it
takes a substantial CO2 cost to overcome this fuel cost disadvantage — about $ 30 / ton, on current fuel price expectations in the U.S.. On the other hand, consider pending investments to add new generating capacity in the United States
over the
next few decades.
I.e. solar activity was high in most of the 20th centiry and then peaked in about 1985, together with a 20 - 30 year heat lag (since it remained high until 1996 as well), and oceans
take a
few decades to equilbrate, (the same as summer
takes about 6 weeks to reach maximum temperature after the summer solstice, and every day it
takes a
few hours after noon to reach maximum temperature), so the earth has
taken a
few decades to reach maximum temperature after the long high in solar activity during the 20th century, and will now go down in temperature
over the
next few decades, with now both a negative PDO, and reduced solar activity.
I can understand that approaching equilibrium
takes a long, long time, while TCR gives a better measure of what will happen
over the
next few decades (and that technology and society may be very different in 200 years time); but on the other hand, I thought nations had agreed to try to limit global warming to less than 2 degrees C overall, and not just to limit it to less than 2 degrees C by 2100.
