"The SSPs feature multiple baseline worlds because underlying factors, such as population, technological, and economic growth, could lead to very different future emissions and warming outcomes, even without climate policy. "
'It means that climate change effects on groundwater recharge happening now will not come into full effect until our grandchildren and great-grandchildren are in charge of the planet.'
James Hansen, director of NASA's Goddard Institute for Space Studies in New York, warned the US Congress in 1988 that human-induced global warming was already underway and 'may have important implications other than for human comfort'.
El Nino is a climate pattern that describes the unusual warming of surface waters in the eastern Pacific Ocean.
Every month in 2020 has ranked amongst the top four warmest for the month in question, with January at 0.03°C warmer than any previous January and May at 0.05°C warmer than any previous May. It is also confirmed that September 2020 is another record-breaking month for the C3S dataset. Arctic sea ice extent for the month of September was also notable, at the second lowest on record, both for the daily extent and for the monthly average extent.
Carbon dioxide from human activity is increasing more than 250 times faster than it did from natural sources after the last Ice Age.
"Warming from increased levels of human-produced greenhouse gases is actually many times stronger than any effects due to recent variations in solar activity."
"Trees are supposed to slow global warming, but growing evidence suggests they might not always be climate saviours. "
"Climate change has about 4-9 per cent impact on agriculture each year. As agriculture contributes 15 per cent to India’s GDP, climate change presumably causes about 1.5 per cent loss in GDP , in India."
- B. Venkateshwarlu , former director, CRIDA Hyderebad
"Negative Emissions Technologies take more CO2 out of the atmosphere than they put in. No one single technology can solve climate change, but many have been proposed that could contribute to reducing atmospheric CO2 ."
"If given just one word to describe climate change, then ‘unfairness’ would be a good candidate. Raised levels of carbon dioxide in the atmosphere are expected to cause deadly heatwaves for much of South Asia. Yet many of those living there will have contributed little to climate change."
-Prof. Chris Huntingford, UK Centre for Ecology and Hydrology
"There is no definitive way to determine the best “pre-industrial” reference point. An alternative might be to avoid the pre-industrial baseline altogether, and instead set targets from more recent periods, when we have a better grasp of what the global climate looked like."
"It depends on where, when, and how."
"More rain saturates the soils or if soils are less frequently frozen, the trees will have less stability to withstand storms and damage will increase. The many dead and dying trees will then provide ideal breeding material for insects such as bark beetles to reproduce quickly. At the same time, the trees that are still alive will be weakened and will thus be more vulnerable to insect attacks."
"Local actions to reduce Urban Heat Island (UHI) effect – such as planting more trees or cooling roofs and pavements – could make a big difference in limiting warming and minimising costs."
"It’s a new atmosphere that humanity will have to contend with, one that’s trapping more heat and causing the climate to change at a quickening rate. "
"Climate-smart interventions including laser-guided land leveling of fields, said to conserve 20% of water resources in fields and increase yields by 15% through greater precision in seeding, tillage and measuring the moisture of soils."
"Can a single climate phenomenon really cause all these events? Is the world just a step away from disaster when El Niño conditions develop? What exactly is this important climate phenomenon and why should society care about it? Who will be most affected?"
"China will see yield reductions of about 3.0 percent per 1 degree Celsius increase in global temperature. And India was projected to experience much greater declines of about 8.0 percent. "
"A global warming of 2°C will be substantially more devastating for the planet’s climate than 1.5°C by 2100."
